Hot Water Boilers
Boilers are very common in the older parts of Ottawa. Most Boilers in Ottawa heat water in order to distribute heat throughout the home using radiators, or Radiant Heat provided by heating and entire surface. Hydronic Heating Systems can transfer 3500 time more heat per volume than air. These are ideal systems for Very Large Custom Homes.

Heat Pumps are basically Air Conditioners that can reverse, but there is more to it than that. Heat Pumps of today can operate with high inefficiencies as low as -30C.

Indoor Air Quality
Heat Recovery Ventilators HRV / ERV
Good indoor air quality starts with eliminating the source of common indoor air quality problems like moisture which can lead to mold, mildew and other unhealthy contaminants. An HRV or ERV Air Exchanger eliminates contaminated air, while bringing fresh air into your home, but recovers up to 95% of the heat.
