If you’ve ever bought a heating appliance only to find it woefully inadequate for the task at hand, you need Christian Hoerning’s advice. A technical expert at EECA Energywise, he tells us how to stay toasty without getting burned by the end-of-month bill:
For larger rooms you want to heat regularly, it’s worth paying a bit more upfront for a fixed heater with lower running costs and more heat output than a small electric heater can provide.
Electric heaters may be enough for smaller rooms and rooms you only heat occasionally.
Avoid unflued gas heaters (either portable or with pipes fixed to the walls) that release toxic fumes and moisture, and open fires that are draughty and inefficient.
Match the size of your heater to the space. An oversized or undersized heater won’t work effectively, and can cost more to run.
To minimise the environmental impacts, choose a heating option that uses renewable energy, like wood, wood pellets or electricity (which is about 80 per cent renewable on average).
Choose the most efficient model for the job, and use and maintain your heater properly – for example, have heat pumps serviced and regularly clean the filters.
Fireplace: The expert advice
One reason wood fires have fallen somewhat out of favour is increasing clean air regulations in our cities. But wood is a renewable resource – and a real wood fire has romance on its side. So if you’re a sucker for the crackle and the ritual of stoking the logs, look for one that is clean air approved for urban areas.
For large, open-plan rooms you can’t go past double-sided fireplaces as room dividers. They visually connect two spaces, and add intimate zones to the setting.
