OPEN-PLAN SPACES AND AIRCONDITIONED ROOMS
For heating large areas Mitsubishi Electric national product manager, Atesh Mani says a reverse-cycle airconditioner is a sound choice, especially for the hip pocket.
“A medium-sized reverse-cycle airconditioner has an average hourly running cost of 48 cents, meaning 500 hours costs around $238, whereas a medium gas heater’s cost will be about $300,” he says. Newer units are even better. “Airconditioning units made as recently as 2002 run up to 40 per cent less efficiently than new models,” he says. “Consumers can expect this to continue to improve as new developments lead to even more efficient appliances.”
Open-plan living is another challenge to heating modern homes, but Atesh says technology has an answer for that.
“This is where zone control functionality can play a big part. Even the biggest rooms will feel the benefit of having the rest of the house closed off and the warmth funnelled into one space,” he says, adding that some ducted systems let you control four to eight different zones.
Keep in mind that for every extra degree on the thermostat, your bill will rise about 10 per cent.
