    As winter approaches people are asking how to get more heat out of those very old hot water radiators. A few tips. Bleed the air out anytime they don't feel hot enough.

  • WHAT'S AVAILABLE IN NEW FURNACES?

    The field of energy efficient heating systems is advancing rapidly and constantly and I cannot evaluate all the new products here.

  • 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...
  • Automatic bleeders for radiators

    For various reasons, hot water heating systems can accumulate pockets of air in the top of the radiators. When there is too much air, the water doesn't flow any more and the heat slows down and stops. For that reason most people have to "bleed" the radiators regularly: open a little valve in the ...
  • WHAT IS AN AIR-TO-AIR HEAT EXCHANGER, HRV and ERV?

    Air-change ventilation systems exist that take stale air out and bring fresh air in so as to not rely on cold air drafts for the entry of fresh air to the house.

    There are several non-destructive ways that we can see what is going on inside the walls, ceilings and roofs of our homes. Simply watching the melting patterns of a light snow on the roof will tell you where you have insulation and where you have heat losses. In the first photo this was an unheat...
  • Important precautions for installing large tiles

    The world of tiles is changing rapidly.  Twenty years ago we generally had a range of tile sizes from 1 ft x 1 ft down to tiny mosaic tiles.  This made tiling relatively simple because slight changes in the flatness of the surface could be adjusted for at the next grout line.  In fact that is...
  • Adjusting the Posi-Temp temperature control shower valves.

    Dan from Toronto, Ontario writes: "I saw your show about installing the Moen Positemp shower system. We had two installed, one upstairs and one in our basement shower. Both work fine for controlling the "shock" factor, but we can't seem to get enough hot water out of the upstairs one. Is there a ...
  • Hiring a Home Inspector

    Is there real value to having a generalist come in and perform a complete home inspection? Yes! I wrote this entry in 2007, and in 2016 I added this note from my Newsletter: “There is a brand new CSA standard for home inspections -- an industry that has been plagued by inconsistency and the abs...
