Solar Heating for Homes in
Newfoundland and Labrador


[Return to Policy Summary Page]

Residents of Newfoundland and Labrador spend $300 or more per month (equal billing) for electric heat. This is $36,000 over the next ten years and possibly much more if electric rates rise.

Switching to cheaper fuels such as wood pellets, or more efficient electric heat (heat pumps) can reduce these costs but a far better solution is to design new homes so that this purchased heat isn't needed. Why spend money to cut heating costs by 25% to 50% when you could permanently eliminate the expense with better design?

Homes that can be heated from sunshine do have increased construction costs due to the extra insulation required, but this is a one time investment that is far cheaper than buying fuel forever.

Solar passive homes warm up significantly during the sunny days and store some of the excess heat in cement floors and masonry. At night, heat is released from walls and floors limiting the temperature drop. If there is enough insulation in a home and North facing windows are eliminated, the heating needs during cloudy weeks can be provided by occupants,and activities like cooking, waste heat from lights and small supplemental heaters.

The video below takes this solar home concept one step forward with seasonal storage. Excess heat from the Alaskan summer is stored and used to heat the home during the dark winter months.

Anyone planning to build a new home would be well advised to spend two hours to watch this. The typical construction methods used for new homes in Newfoundland and Labrador are primitive and ill conceived from an operating cost perspective. For those of you with limited time, here are some highlights:

There is no reason we cannot build homes like this in Newfoundland and Labrador, and it should be government policy to mandate this kind of construction. A housing stock (moving forward) that dispenses with heating costs not only enriches the population (e.g. $300 extra spending money or alternatively, not being miserable when you cannot afford heating oil) but also allows the province to live of the existing hydroelectric resources. The small amounts of electrical power required for LED lighting, refrigerators and electronics could be provided with a small solar array.
