Your home

There are many things you can do to make your home warmer, healthier and more energy efficient. Generally homes in New Zealand waste energy. They can be badly designed and constructed, have inadequate insulation or use a lot of energy to heat and run. 

Key elements of a warmer, drier and healthier home

To really make your home warmer, drier and healthier to live in, it is important to think about how insulation, heating, ventilation and tackling dampness work together as a system.

By thinking of each element as one part of the whole puzzle, it's easier to see how getting each part sorted contributes to a more comfortable and healthy living environment.

Tackling sources of excess moisture and dampness and insulating your home are jobs that only need doing once, and are worth doing properly. The initial costs are more than paid back in better comfort and health for your family and reduced energy bills.

Heating your home properly is easy and relatively cheap once you have good levels of insulation installed and have a correctly sized and installed, efficient type of heater in your home.

Ventilation is often neglected, but getting into the habit is essential for creating a healthy home.

And, when it comes time to replace things, good choices will give you systems that meet your needs using a lot less energy.
