Goodbye gas — disconnecting the ducted heating
Show 0 more photos Show 6 more photos Hide additional photos
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 electricity for the fans, which is about what our air conditioner used to maintain a warm temperature, once reached. Our battery provides backup power during a grid outage.

So I doubt your word.
Only reason MUST be you have shares in the fossil fuel industry.
Why else would you be trying to protect it? There is no other logical reason for it at all
Seriously, claiming that RCAC doesn't work in the Dandenong really cements the fact you have NFI. It's not that cold you fucking bottomfeeder.

The gas heater has a condensing burner, it’s about the most efficient way of using the gas to heat.
I think your mind can’t process the basics behind these principles
Report
You will also never get free reticulated gas, whereas the government is bringing in 3 hours free electricity available for most of the country, so even if the efficiency was the same you could still save money with electric heating.
Anything you're unable to understand there?

He then go on about the Dandenongs being cold, so "cold" means for him "no heat".
No one in the industry will be so stupid.

Electric and induction are two different things
Report
Gas is lit.
Report
Are you 21 now?
Induction, at homes, is pretty new.
It uses to be very hard to run induction at home. It was expensive and required 3 phase.
You might wanna try again.
Just to know what the options are.
Report
Report
But yeah, induction is completely different to electronic element.
It's not heading transfer, but magnetic energy that vibrates the imperfections in the metal, leading to heat created directly in the pan/pot.
That's why it's so quick and efficient.
It also allows for very accurate control over the heating and cooking.
Plus, no gas.

"Cold" doesn't mean " no heat".
Also, you'll be stocked to hear they have electric element to boost if needed.
Being cheap to run, at can run all day to heat the water for evening showers even when it's "cold" outside.

Since you asked: Our Tesla car has been fantastic. Zero smell, quiet, super fast, practically no maintenance. And we mostly fill up the “tank” for free from the sun. But that’s the same with most EVs.

We also have 2 split system heater/cooler air cons, a heat pump hot water and induction cooktop, no gas at all. Our 2025 electricity bill including charging the EV for about 25,000kms a year (some days solar) and also the 6.6kw solar array and a Tesla PW2 house battery, for the ENTIRE YEAR was $424 and the year before was $509 as I drove the car probably closer to 35,000 kms that year.
This is with OVO energy.

I’m all for saving money but don’t we need to consider the capital outlay repayment, loss of potential earnings on capital outlay or interest expense if funds are borrowed?
All good to say you don’t have a bill, but what has it cost to not have that bill? And when is the projected break even?

But, you are right, that there was capital expense up front.

You said one need to consider ROI.
I said it's normally 6-7 years.
Report
Simply mentioning ROI without any analysis is pointless, not all investments are successful.
Report
It might be a bit less it a bit more, but it's still around this area.
No one think solar is free, but if someone goes all electronic, the ROI changes dramatically due to the native efficiency gain over other domestic energy sources.
Report
Yes, I paid for a new car.
Which I would have regardless.
The investment in new solar and battery, $23k in my case, not directly hugely contribute to the saving since I normally charge from the grid over night at 8c/kWh (unless it's going to be a fully sunny day), but the fact I have EV, allows me to charge the battery at 8c, even if tomorrow is gonna be miserable.
It's pretty hard to estimate the saving over time, but it's huge.
Getting rid of gas will save $1.5k-$4k a year, depends on how cold the winter is.
One thing is clear, the ROI is huge over the life of a system

The 10kwh for $10k made no sense.

Facts are, most people won't ever pay off the battery and solar in their life time as they sell the house within the calculated pay off period.

Strange.
1. Induction cooking uses energy to heat the vessel rather than heat transfer from burning stuff.
Many times more efficient and quick.
2. Big enough battery and invertor (10kw is the norm for 1 phase) keeps the whole house running, lights, a/c oven, induction. Easy.
3. The new battery systems design to provide instant blackout protection.
It works while the grid is out.
The switch is so quick, you don't even know the power is out.
But you do you.
You know better.
I guess today's power outage that I didn't know about until I got the battery system notification was not real.

1. Two years ago, we installed 13kW solar and 13.5kWh battery. It was an up front investment which has saved us thousands of dollars so far.
2. It initially just covered our basic electricity. But now, every additional gas system we move to electric incurs no additional ongoing cost for us, so running them is effectively free.
3. We haven’t been charged for any net grid electricity since then.
4. During a grid outage (a blackout), the battery fully powers our home, and recharges from solar each day.
5 Our longest grid outage so far was nine days. We ran extension cords to our neighbours to keep them going too.
6. The reasons I am not off grid all the time are: Sometimes I want to draw additional electricity from the grid during cheap times (eg when wind farms are pumping on a dark day); When I have excess energy and the grid price is high, my system exports, so I get paid for my contribution.
7. I can monitor our electricity usage in real time via connected apps. That’s how I can tell you that our living room air con used about 1kW to maintain temperature. It uses more initial to reach that temperature.
We have posted about each step along the way, successes and failures, on our Tesla Tripping blog.

The government are paying for more than half of your battery and solar set up and he’s still just breaking even is solar and battery were more cost-effective. They wouldn’t need to subsidise 
Report
The amount that the government subsidises the fossil fuel industry is eye watering, and that money mostly goes off shore. I’d much rather have my tax dollars subsidise Australians to make their own power.
