Solar Space Heating

SolarOntario can, and does, design & install solar space heating systems. The systems work and people are happy with them. However, we want people to know that solar space heating can only supply a portion (typically a small portion) of the space heating load. These systems are not inexpensive and the payback is very long.

SolarOntario.com Ltd. favours the use of water-based solar space heating systems over air-based solar heating systems. Many of the components used in solar space heating applications are also found in solar domestic water heating systems.

There are air heating solar collectors designed to deliver heat directly into a living space when the sun is shining. These products do not (and cannot) incorporate any for of heat storage - so when the sun goes  down, they  can no longer deliver heat.

25 - 30 years ago, air collectors were built with rock heat-storage systems. There were many issues with moulds and heat leakage that caused the concept to be abandoned. The cost of running the fans used for moving the heat around also tended to cancel out a large part of the savings.

Water or anti-freeze based solar space heating systems are often incorporated into radiant floor heating systems.
