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.

Seriously, why do you go around posting on things you know nothing about?
Do you have a lot of money invested in natural gas or something?
Why would you care what other people do to reduce their costs?
The 540 came from the author….
It’s ok, you have post numbers, they are bogus….
It pays for itself pretty quickly by eliminating our fuel bills (car and house). In the past two years, we haven’t yet had to pay an electricity bill, or petrol bill. And soon, no gas bill.
Some of our battery experience:

Not sure where you bring this idea from
Normally it's 6-7 years.
That’s not my point champ.
Cold climate, with a bill that large a poorly sized heat pump system will not work, unless your idea of warm is 15-18 degrees.
This isn't a climate where you get shit tons of snow.
Seriously, you're clueless about this subject.
How many shares do you have in natural gas? Why do you care so much that people are choosing a cheaper option?
Is that what you're saying?
Because you definitely know nothing about RCAC and what temperatures they can operate under.
In places like Texas where you get sub zero temperatures for periods is where you have problems. Not in Australia.
Time to hang up the boots and go work at Woolies.
I think it’s time you jump into NDIS cobba, you clearly are delusional and need help
Yeah changes nothing champ.
Hang up your boots. You have NFI.
Why do you jump on this sort of stuff huh?
You hate EVs too I have seen. Anti-renewable too.
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.
Spider…
The venom has gone to your little head…
I get energy free 11-2pm from the grid which heats my house and runs my cars
And I'm a rocket scientist
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
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.
During last winter, in the months where we avoided turning on the gas, we ran an old 7kW air con in the living room, and still had no net electricity bill for the year.
Stuff using elec cook tops. Annoying asf
Hot water? Hmmm instant hot water with gas.. my bills are less then 80 a month

Electric and induction are two different things
Gas is lit.
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.
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.
That's including all house usage and fully change the EV.
I pay only connection fee and not using any imported electricity.
I have almost 40kwh battery, so it's enough for everything.
I don't include solar pay because it's piss nothing.
I never import outside of the 00:00 - 06:00 super off peak.
Started with 24kwh, but the additional modules to go up to 38 was funny money, so went up.
I'm not using it even if I try.
Still export heaps.
I remember living in the tropics, you can't have enough power! Still, great result getting to 90% self sufficiency. Chasing the last dollar can be too expensive actually.
I guess you never used one?
I dunno, my hot water in the tap are the same hot that everyone else.
Only cost me fraction of the price.
But you do you.
"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.

Got showers and saving 1000$ a years just on not having gas.
I have one. It works. Exactly as advertised.
I'm pretty sure reality tells a different story than a random cooker on Facebook
Do you have other calculations you have on mind?
He has the best energy source, why go back to a less effective one?
https://www.facebook.com/share/p/17xtnGjv2E/
I preferred cooking with gas until I tried an induction stove – cooks faster, more controllable, no smell.
And I guess you never tried induction.
Love it.
Enjoy.
Enjoy them bills.
This time, we’re getting a multihead split system. I’ll also post about how that’s going.
- Gassftter to decommission heater
- Mechanical services for ductwork
-Full refrigeration for multi head system
-Sanitary plumber for any drains connected to sewerage such as sinks etc.
-Roofing for all roof penatrations
-Electrician for all wireing
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.
We love fires and floods.
It'll be a very long wait for the crying part.
In the meantime, it looks like you're crying right now, cooker.
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 invest, pay less, return the money and start saving.
Simple economical concept.
You said one need to consider ROI.
I said it's normally 6-7 years.
Simply mentioning ROI without any analysis is pointless, not all investments are successful.
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.
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.
My 48kwh for about $6k did.
ROI is not the only consideration.
Couple of weeks ago the heat pump and the induction cooktop went in, the gas guy came to cap the gas (I'll get abolishment soon).
Big battery and solar array.
Will save close to $5k a year with this change
Spend thousands in BAL compliance and Gas bottles are good to go!
Poor argument.
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 
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.
