Did going all-electric cause our mould?
We spent 2025 and 2026 getting off gas — heat pump hot water, a multi-head air conditioner replacing the ducted gas heater, and finally an induction cooker. Then we found mould on the bed slats. Was it due to electrification? We first found this same mould, on these same slats, in December 2024 — fourteen months before the air conditioners went in, while the gas ducted heater was still doing all the heating. Whatever causes it was here first, and it was here while the gas was. Gas cooking turns out to actually make it worse. Burning gas makes water: roughly 1.6 kilograms of water vapour for every cubic metre burnt. That is on top of the water coming out of the food or boiling water, which happens whatever you cook on. Going induction removed the extra moisture. Not to mention the benzene, which is a known carcinogen. What did change is the ventilation. The old ducted system leaked, and those leaks quietly brought in outside air. Reverse-cycle doesn't leak. Better heating, staler air.…

Our heating doesn't breathe
Last post we found the mould. This one is about where the water was coming from. I assumed the ensuite — showers, obviously. That is a real part of it, though not quite as I pictured. The door stays shut and the fan runs while we shower. It's afterwards that the moisture gets out: the fan goes off, the door opens, and the wet walls, floor and towels carry on evaporating into the house for hours. But it wasn't the whole story, and working out the rest meant unlearning how I thought our heating worked. Here's the misconception, and I held it for years. You switch on the air conditioner. The big fan in the unit outside starts spinning. Air blows out of the head on the wall inside. Obvious conclusion: that fan is pushing outside air into the house, warming it on the way in. Wrong. No new air comes in at all. The outdoor unit and all that white insulated pipework only move refrigerant gas, and the gas never enters the room. It just makes a hot surface inside, and the head blows the room's…

Does size matter? Tesla Model Y vs YL.
A six-seat Tesla Model YL turned up at the Worldwide Light Show meet — parked right next to our red Y, captain's chairs and all. Tesla had loaned it to Garry from TOCA (Tesla Owners Club of Australia), Victoria for a few days to bring along to events like this one, so we got to climb all over it before the show started! Likes: - The captain's chair armrests in the second row — cleaner than the bench in our Y. - The sub-trunk lid that magnetically clings to the back of the seat when you flip it up. Lovely bit of engineering. - V2L! We would love to have vehicle to load on our EV, like most models now have. If only we could cook food on our induction cooktop, while camping, from the massive battery in the car. The Tesla Model Y L and new Model Y Performance both have V2L. Unsure: - Six seats vs our five. The third row is tight — elevated floor, very little leg room. I had to stick a leg out into the aisle just to half-fit. Climbing in and out takes some practice. - The captain's-chair…

Why ducted air conditioning is inefficient
Ducted air conditioning (or heating) is inefficient. Let me explain, and see what you think. I am not a fan (pun intended) of ducted. It seems to be very inefficient. But only one in five air con sales reps seem to agree with my reasoning. At our previous home, in Saratoga NSW, we had a large (10kW) ducted air con system upstairs, which included all the bedrooms. When we just wanted to cool or heat one room, we tried to close the door of that room. But the door would slam shut and whistle, as the air would try to escape. The ducted air con had one or two outlets in each room’s roof. It had one shared return vent in the hall. Turning on the air con in a single room, the air needed to return to the hall to circulate. Closing the door blocked that path and made the pump work extra hard. The thermostat was also in the hall, as part of the control unit. We could set the target temperature of a room to say 22°C, but the room might cool down to 18° before the hall thermostat would register…

Goodbye gas — disconnecting the ducted heating
Goodbye gas! I finally organised disconnecting the ducted gas heating at our home. If only we could see the burnt gas pouring into the air, all the time, and not just when the condensation highlights it (as in the photos). Pumping carcinogens and greenhouse gases into the air that we breathe. It’s nuts. It was costing us up to $528 per month to run the heating in winter. Our replacement air conditioning will be closer to free, thanks to our solar and battery. We recently also replaced our gas hot water with a heat pump. Our one remaining gas appliance is our stove top. Once that’s gone, we will save $35 per month just for the connection fee. And no more gas! We’re replacing the gas heating with some split air conditioners. For those who might say “what about in a blackout”? Note the power point connection on the old gas heating. Our old gas hot water heat pump had one too. They both needed electricity to run. In fact, in addition the gas consumed, the heating used about 1kW of…

Multi-head air conditioning installation, stage 1
The original plan was to install a multi head system, with five heads (one in each of five rooms), and one shared compressor, outside. Due to a change of plans (see “Problems” below), we end up with three heads on our multi-head system, covering our downstairs living area (lounge, dining, kitchen), master bedroom, and guest room. Configuration: Shared compressor: 18kW (though much lower in actual use) Head 1: Master bedroom: 2.8kW Head 2: Guest room: 2.8kW Head 3: Living area: 8.4kW Cost: The original quote was for a five head system, including two more 2.8kW heads and a slightly larger 20kW compressor. $14,776 Emerald 20kW with 5 x heads -$7,140 VEECS discount -$386 EOY Sale $7,250 Total inc GST Inclusions: Removal of Gas ducted system 1 (no duct removal) Double storey We paid about 20% deposit up front, and the rest on completion.

First Tesla service call: a new wheel
First service call for our Tesla Model Y. Replacing our loaner wheel with a new wheel. As you can see in our posts from a few weeks ago, we hit a pothole, damaging our left rear wheel. At the time, we only knew that we had a slow leak. We logged the problem in the Tesla app. They arranged for roadside assistance to come to us, in about an hour, to install a loaner wheel, and take ours away to diagnose. Today, Tesla replaced the loan wheel with a new wheel, costing a whopping $1319. I asked them to clean the damaged wheel and put it in the back of the car. In the photos, you can see the buckle and crack. I am wondering if it is fixable. When I booked this service in the app, I also asked them to fix the water in the light bar, and some issues with the steering wheel buttons. They replaced both. I’ll discuss the steering wheel buttons in a separate post. All covered under warranty. I had a bit of trouble figuring out where to leave the car. Several after me also mistakenly parked in…

Oli burger and FSD on the Hume Highway
Lunch stop at Oliver's, just outside Gundagai. I recommend the Oli burger 🍔. Tesla Model 3 with stripes parked near us. FSD along most of the Hume Highway. It does a great job, and avoids human fatigue. A few complaints, though, including it repeatedly thinking that the speed limit is 100, even when it’s actually 110 (pictured). Occasionally it dropped to 80 or 40, presumably after seeing some random sign off the highway. Pretty good driving efficiency with FSD, too, about 14kWh per 100km. See screenshots.

Savic test rides through the Dandenongs
While driving in our town of Emerald to get some Emerald Thai for dinner, I did a double take when I saw a Savic Motorcycles sign, randomly on the footpath. It turns out that they were running test rides today “winding through the beautiful Dandenong Ranges”. What a great idea! Test drives at dealerships and even EV shows tend to be within urban sprawls, which doesn’t offer much of a driving or riding experience. We’ve seen Savic at a few EV shows, including the recent Everything Electric in Melbourne (pictured). I wish I had known it was on, and that we weren’t recovering from a cold right now. Hopefully next time. Savic is an Australian company building electric motorcycles.

Solar, battery and electrification — series intro
A few neighbours and friends have asked us lately for advice about solar panels, house battery, EVs etc. Here’s our real life experience, starting a series of posts on different topics. We installed solar and battery when we moved into our house (Emerald, Victoria) about two years ago. We already had an EV (electric car). This week, we finally got around to replacing our gas hot water with an electric heat pump. Next month we’re replacing our gas ducted heating with a multi head split air conditioning system. Overall, our solar and battery provide more electricity than we use. We’re also connected to the electricity grid so we can import when we need more, or export when we have a surplus. We aim to produce all the power that we need. On the rare times that we import electricity from the grid, our retailer bills us. More often, we export our surplus electricity to the grid, for which they give us a credit. Overall, we have more credit than debits, so we don’t have to pay anything. All…

A solar-powered coffee stop at Glenrowan BP
Coffee stop, just north of Glenrowan, at the BP service centre. The Tesla/Google navigation only knew the south bound service center here, so the directions tried to send us over the highway 🤪. Thanks to the nearby solar farm that provides the power to the grid that found its way to our car. We overheard someone paying $1100 for fuel, presumably a semi trailer. Wow. 😮 Home baked Anzac slice (thank you Krissy) was the perfect accompaniment for the coffee and thermos of tea. The small birds begged us for crumbs. On towards Wagga.

Why we ordered a Model Y 'Juniper' launch edition
Back in January, we took the plunge and ordered a new Tesla Model Y “Juniper” launch edition. “Ultra Red”, white interior, 20” wheels (which was the only option for the launch edition). We chose the same battery and drive as our Model 3: RWD (rear wheel drive), LFP battery (no nickel or cobalt), 0 to 100km/h in 5.9s. The main reason for the upgrade is for the greater ease of getting in and out of the car, which has been increasingly painful on Fran’s arthritic hips. As those of you who follow our Tesla Tripping blog will know, we have looked at and test driven quite a lot of other options. The best contender was the XPeng G6. In the end we stuck with the Tesla Model Y because of the huge storage space, driving performance and the tech. The Tesla app has guided us through the whole process up to now, with registration, trade-in, insurance. Today is delivery day. The final `Start` button is still disabled in the app. I’m guessing it will enable at exactly 3pm, when we’re at Tesla…

Kia EV6 vs Tesla Model Y, test drive
Feb 1: Test drive of a Kia EV6. Forgive the dust in the photos. Highlights, comparing to Tesla Model Y: - Good acceleration. Handles okay. - More physical buttons (good or bad, depending on preference). - Manual, not auto, adjusting steering column. - Much less storage. - Smaller main screen. Blind spot camera is on an additional smaller screen, behind the steering wheel … in a blind spot! At least, I couldn’t get a good view of it, which defeats the purpose. - HUD (heads up display) was a new discovery for me. It’s terrific to see your speed within the field of view of the windscreen. - 240V V2L outlet in the car, which is great. Apple Car Play. Missing in a Tesla.

Our 25-minute Model Y 'Juniper' test drive
Our first (and only) test drive of the new Tesla Model Y “Juniper”, at Tesla Mulgrave. We only had 25 minutes in the car, which isn’t much to fully test it. Not enough time to drive to some winding country roads, but we did manage to find a tightly curved on-ramp to a highway. Driving at speed around it, we definitely noticed more body roll compared to our sportier Model 3. This did freak out my passengers. They also found the acceleration more noticeable in the back seat, which seems to tilt down. Tim described the acceleration as prolapsing his sphincter. The Model Y absorbs bumps much better, finding a good median between sport and comfort. This new model has the same acceleration as our Model 3, 0 to 100km/h in 6s., one second faster than the previous Model Y. This is the RWD (rear wheel drive) model, standard range, not the AWD long range. We prefer the RWD because it has an LFP battery, which has no nickel or cobalt, and a longer life span. It’s also cheaper. But slower…

XPeng G6 — second test drive
We took another test drive of an XPENG G6, this time from a new dealership in Berwick, Victoria, which is closer to us. Nice interior, comfy seats, great tech. The handling wasn’t bad on some windy roads, but not as sporty as the Tesla Model Y. Disappointing storage. The auto driving hesitated quite a bit around bends. The lack of full stop on one pedal driving is annoying, but they will reportedly solve that in a few weeks via an OTA (over the air) software update. The G6 includes auto parking and lane change, which costs extra in a Tesla. It has vehicle to load, but it requires some adapter plug into the external charge port, which wasn’t available. We had a chance to play with Apple CarPlay, which is great to have. But the XPeng doesn't seem to support pinch and zoom in Apple Maps, which makes it very limited. Acceleration was terrible (doesn’t move for a second), until I turned in “launch mode”. I couldn’t figure out how to enable launch mode and regenerative braking (x-pedal) at…

XPeng G6 — first look at the Everything Electric Show
The Xpeng G6 is a strong competition against the Tesla Model Y. We viewed both at The Everything Electric Show (Everything Electric) in Sydney. A few weeks earlier, we took a G6 for a test drive at the XPENG Port Melbourne showroom (also pictured). The Xpeng G6 and Tesla Model Y both have great tech, great efficiency, ventilated and heated front seats. The G6 doesn’t have frunk storage, has small subtrunk storage, smaller boot, no glovebox, but has a bit more rear passenger room and probably more comfy seats. It has Apple Maps and Vehicle to Load (V2L). It is $10k cheaper, but requires paid regular servicing and and has longer warranty. It includes auto lane change (extra purchase on the Tesla). The Tesla has faster acceleration, sportier handling, one pedal driving comes to a full stop without the brake, and has more fast charging options. It has a screen for rear passengers and powered rear seat folding. It has much more storage overall, including huge sub trunk, boot and frunk. It…

Tetris-ing four people, a fridge and luggage into a Model 3
We know our Tesla Model 3 can fit a 50L camp fridge. And we know it will take a large travel suitcase, or four people and some luggage. But we didn’t know if it would take all that at the same time. It took a fair bit of Tetris-ing, and the boot strained at the seams, but we managed to get everything in. I think we might need a bigger car. First stop at Eumundi Markets. We parked in the shade and later opened the boot so the fridge had some outlet for the hot air. Second stop along the highway at Burpengary for some fast food lunch. Then we delivered Erin and Isaiah to their accommodation in Brisbane before their flight back to Airlie Beach tomorrow.

Borrowing Nico's Jaguar i-Pace
On our way from Krommenie to Maastricht. We picked up Nico’s Jaguar i-Pace. Very swish. 0 to 100km/h in about 3.5s. Luxury interior trim. Neat console. It has fast DC charging but only does 3.6kW AC charging (compared to our Tesla’s 11kW). It’s about twice the cost of our base Tesla Model 3 at home. Jaguar had it for a few days to replace the battery. This is the first real example I’ve seen of someone actually needing to replace their EV battery, despite all the hype about it from naysayers. Fortunately, it was all covered under warranty. Our first stop was in Breukelen at a service center. Well, we actually stopped at two of these, because of mixed up convoy instructions. Next to the Shell petrol station here is a FastNed charging bay, with solar panels on the roof. Most service centres seem to have these, which is terrific. It kills me to stop for fuel like this. Stopping specifically for fuel (charging) is something I try to avoid. I prefer to just charge when I’m parked for some…

We bought a Mammotion robot mower
We bought a new EV! It’s all wheel drive, includes full self driving, with proximity sensors and just a front facing stereo camera. But it takes about four hours to fully charge and the acceleration is pretty slow 😉. It’s a Mammotion Tech Luba 2 robot lawn mower. We could have bought it online direct from Mammotion, but opted to buy it through a local service centre, Robotech Australia, just in case we need support or maintenance. Our lawn is about 1500 square metres. We bought the Luba 2 AWD 3000 model, which is rated to mow 3000 square meters, allows up to ten mowing areas, and handles extra step inclines. The base model does 1000 square metres, and allows less separate mowing areas. There are also 5000 and 10000 models. I followed the fairly simple hardware instructions to screw in the camera (which looks like Wall-E), screw the charging station into the ground, and assemble the transmitter (RTK) onto a pole. We have named the robot “Marvin” (the mower). To misquote Hitchhiker’s…

Preheating the house from John's Hill Lookout
After a beautiful morning drive in the Dandenong Ranges, with our last stop at John’s Hill Reserve Lookout, we decided to head for home, about 20 minutes away. It was 6°C outside but warm and toasty in the Tesla. Our house was going to be cold 🥶. If only there was a way to heat it up remotely, before we got home, like we can with the Tesla 🤔. Fortunately, there is! We bought a Sensibo remote control. It communicates with the air conditioner via infrared, and communicates with our phones via the Internet. It even works with our ten year old Panasonic air con. So, we can be in bed, or many kilometres away and say “Siri, turn on the air conditioner”, to have a warm lounge room waiting for us. We can also control the temperature, fan speed, schedule and so on. We could even set it up to turn on the air conditioner automatically when we’re within 20km from home, via geofencing. Nice 😊 We opted for the “Air Pro” version, which also monitors air quality. I’ve noticed that it sometimes shows…

First delivery to the new home
Our first delivery to our new house – a congrats savoury box from The Hamper Emporium from Mortgage Choice in Tumbi Umbi. Thank you John and Amanda. What a nice surprise 😋 . John sorted out the loan for our previous house in Saratoga NSW, and now this one in Emerald Victoria. It’s been a long road, figuratively and literally. We packed up and left our old home on December 1 last year. We’ve been road tripping most of the time since then, and hope to finally move into our new home in a couple of weeks. We didn’t intend to take that long to find a new house. Our “pre approved” home loan with ING turned out to require additional financial info, which was difficult to do while we were on the road. I recall voicing our frustrations over the phone while driving through some country road out the back of nowhere. In any case, that pre approval expired after six months and banks started limiting new pre approvals to just three months. I’m not sure how they expected buyers to find a home in…

A bug-spotted windscreen, with no clean-up
Final leg to the NSW Central Coast today. First stop for bladders, so we pulled into the next service center along the Hume Highway. A fresh spotting of bugs adorned the windscreen. But there’s no cleaning facilities at the chargers 😞. We pulled into the adjacent service station. I opted for the least busy section, which was for trucks, planning to get out quickly. I grabbed the handle of the cleaner from the bucket, and wiped the windscreen a few times. When I went to dry the drips from my hands, I realised that the handle was covered in grease! And now also my right hand. It took some time and effort to get that off, so as not to wipe it on the white interior of our car.

Tyre rotation — and a recommended replacement
Slightly overdue for another tyre rotation (16,700km since previous check, but due at 10,000km intervals). So, I booked one in via the Tesla app, which quoted $71.28. Mobile service came to me. Amar, the Tesla technician, was very friendly, efficient and helpful. All his tools were in the trunk and frunk of his Tesla Model S service vehicle. He showed me that the tyres had unevenly worn, so the inside tread (on the right in the photo) was below spec on all tyres, requiring the replacement. He said he could cancel today’s call-out (so, no cost to me) and book in a tyre replacement at the Tesla service centre (big cost). I asked him to make it so.

Windscreen replaced at Tesla Mulgrave
We followed the instructions in the Tesla app to bring our Model 3 to the service centre at Mulgrave. Great system. We were getting the windscreen replaced, because the chip is larger than the 2.5cm limit of repairs and we had elected the extra windscreen cover with NRMA Insurance. Glad to see that a loan vehicle is standard issue, from Tesla. At the drop off desk, we requested a Model Y, so we could try it out for the day. We explored the bigger storage space and potential sleeping/camping space. When we first hopped in, it felt like a mini van compared to the Model 3. It felt very high. Easier to get in and out. More visibility out the front window, due to the height. Less visibility out of the rear window, partly due to the smaller area (which actually wasn’t so bad) but more due to the extra tinting on the rear window. The roof window visibility is great. We watched some kind of air show (perhaps the Roulettes?) flying over Melbourne while we waited in traffic. The Model Y is…
Formerly: Tesla Tripping
Come along on our EV road trips around Australia and Europe, and follow as we progressively electrify our home in Emerald, Victoria.
Join us on the road. We set off in late 2022 and drove eastern Australia in our Tesla Model 3 — Sydney, Dubbo, Armidale, Brisbane, Cape Tribulation, then down through Queensland and back. We've since upgraded to a Model Y.
We've kept exploring — Uluru, the Snowy Mountains and Gippsland, and a longer run through Europe in 2024. There's plenty more on the map, so come along for the next leg.
At home in Emerald, in Victoria's Dandenong Ranges, we're progressively electrifying everything: rooftop solar, a home battery, a hot water heat pump, air conditioned heating and cooling, and EV charging straight from the sun. We're going fully electric, off the gas.
Got questions, or insights of your own? We'd love to hear them — please drop a comment on any post.
