  • OVERVIEW: Frozen pipes: Tracing, thawing, preventing.

    As weather patterns change we are getting longer colder periods than traditionally in many areas of the country -- and with that, more and more complaints of water pipes freezing. Finding the frozen point can be difficult, thawing it can be problematic but if you have done those two, go one step...
  • WHAT INTERESTING HEAT PUMP VARIATIONS WILL WE SEE IN THE FUTURE?

    Heat pumps of the future will be the key to effective use of "low-grade heat".-- They will be included in the exhaust of HRV ventilation systems to extract that last little bit of usable heat before throwing the stale air out. The exhaust air will probably leave the house colder than the wint...
  • OVERVIEW: Portable Air Conditioners - single or double ducts?

    All air conditioners have a passage for room air to flow into the unit, flow over the cold side of the compressor coil and return to the room. This both cools the air and condenses some of the moisture out of the room air, which makes the room dryer, more comfortable and easier to cool. Wit...
  • Compare: Ground Source Heat Pump vs. Propane Furnace

    An e-mail from Roger in Cambelleville Ontario:We have just started to build our home (3300 sq. ft.) and I recently found out that natural gas is not available. So the great debate begins on what fuel source to use. I have narrowed down my selection to radiant heat using a propane to heat the ...
  • WHAT ARE THE LIMITATIONS OF A HEAT PUMP?

    -- Air-source heat pumps derive their heat from a radically varying heat source -- outside air. The colder it gets outside the less efficient they get, declining rapidly from 0 degrees C and generally being unable to heat a house at minus 15 degrees C. Therefore, they require a backup heate...
  • HEAT PUMPS - an introduction

    Heat pumps do not create heat. They simply pump it from one place to another, either raising the temperature or lowering it in the process. It's much like a water pump: that doesn't create water, it just move it to wherever you need it. Heat pumps are valuable because it takes less energy...
  • WHAT IS A CANADIAN BREED HEAT PUMP?

    Heat pumps, although not invented in the United States, were highly developed there for air conditioning. It was discovered that they could be operated in reverse and provide heat to houses in winter as well. For these reasons it is not surprising that certain design characteristics reflect...
  • Tri-Energy Controller -- a step further towards energy efficiency

      ABC Hybrid Inc. has really broken the code on heating comfort and economy.  Your existing furnace goes totally on or totally of according to the demand of the thermostat.  That is very much like having a stick shift car with only neutral and third gear – you would be in high gear, or out of ge...
  • WHAT ARE WATER-SOURCE AND GROUND-SOURCE HEAT PUMPS?

    Water-source heat pumps work the same as any other heat pump in principle, but instead of having a radiator sitting outdoors, a pump pulls water out of some underground water source or lake, runs it through a radiator inside your basement, and dumps it into a second well in the ground or back int...
  • Is a Dual Energy electrical rate program worthwhile?

    Many electrical utilities across the country offer a "Dual Energy" rate program. Before trying to decide if it is appropriate for your house, you should understand why the utilities have created this system. Peak demand control Electrical utilities have to be able to supply all the electricity...
