COMPARE GAS HEATER AND AC RUNNING COSTS
There are no end of myths about this but at the end of the day what we’re comparing here is thermal energy. How much of it is produced, by what and how much does it cost.
About as close a comparison as you can get is the Braemar THM623 ducted gas heater. This is the only 6 star gas heater in the world, so you know efficiency is right up there. It produces 22.5kW of thermal energy when running flat out during which time it will consume 88MJ of gas.
Against this we’ll put the new Daikin FDYQ200L, the latest in a long line of quality products from the world’s leading air conditioner manufacturer. This system, when running flat out, produces 22.4kW of thermal energy and consumes 6.17kW of electricity.
So, assuming we’re running on the AGL Freedom 3+ plan for gas and using the second band, as the first will likely be used by cooking and hot water, one hour of running the Braemar THM623 will cost $1.70
Against this the Daikin FDYQ200L will consume 6.17kW of electricity. The cost here is not quite so simple as there are several different tariffs on the AGL Freedom 3+ electricity plan.
- On peak rate the cost would be $3.19
- On shoulder rate the cost would be $1.30
- And on off peak it would be $0.80
So, a real world example? Let’s use the same example for the Braemar THM623 as I used on the ducted gas heating running costs post…
So, it’s going to be a really cold night and Mum turns the Braemar THM623 ducted gas heater on at 3.30pm; she sets set point at 20C and makes sure all external doors and windows are closed.
