Heating makes your home healthier and more comfortable to live in. Heating also reduces the growth of mould, mildew and dust mites. The World Health Organisation and New Zealand’s Ministry of Health recommend these temperatures in your house:
- a minimum of 18˚C during the day, or a minimum of 20˚C for more vulnerable groups like children, the elderly and people who are ill
a minimum of 16˚C in your bedroom overnight.
For larger rooms that you want to heat regularly, like a living room, a fixed heater with lower running costs and more heat output is recommended.
Electric heaters may be enough for smaller rooms and rooms you only heat occasionally, like bedrooms. Avoid unflued gas heaters (with pipes fixed to the walls or portable) which release toxic fumes and moisture, and open fires which are draughty and inefficient.
Match the size of your heater to the space you want to heat. An oversized or undersized heater will struggle to heat your room effectively, and can cost more to run. Ask your heating supplier for advice about what size heater will suit your needs.

Unflued gas heaters and portable LPG heaters
Unflued gas heaters, including portable LPG heaters, don’t have vents or chimneys to carry away emissions like water vapour, nitrogen dioxide and carbon monoxide. These emissions can make your house damp and harm your health, especially if there isn't enough fresh air ventilation. Portable LPG heaters can also be a fire risk.
If you do use an unflued gas heater, keep at least one window open to allow fresh air to enter the room and waste gases to escape. Never use them in bedrooms.
Portable LPG heaters are also the most expensive form of heating. If you can’t afford an effective, fixed heating option, consider portable electric heaters. They’re cheap to buy, cheaper to run and much safer than portable LPG heaters. For more information, click on the link below:
