Heating your home

When you’re choosing the right heating for your home there are several factors you need to consider, including the amount of heating you need, the running costs and the environmental impacts of the different options.

Healthy temperatures

The World Health Organisation and New Zealand’s Ministry of Health recommend these temperatures for the rooms 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.

Insulating first

Before looking at heating options, sort out your insulation - you'll be able to use a smaller heating system and your home will be cheaper to heat and cool.


Heater size

It's important to match the size of your system to the space you want to heat. Ask your heating supplier for advice about what size heater will suit your needs.

Running costs

Running costs can vary a lot depending on your fuel price and how well you use and maintain your heating appliance.

Environmental impacts

To minimise the environmental impacts of your heater:

  • choose a heating option that uses renewable energy and produces fewer greenhouse gas emissions
  • choose the most efficient model for the job
  • use and maintain your heater properly.

Heater type

How you use a room will help decide the type of heater that’s most suitable - for rooms you use regularly it’s well worth investing in fixed heaters, but for rooms you use occasionally electric heaters may be enough.
