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 ...
When the contractor installed a new furnace, he put in a great big air duct from outdoors right into the furnace room. This tends to freeze the basement floor. Can I close it off?Response:This duct is necessary in most modern homes and even in well sealed renovations to assure adequate air f...
Stale, humid air must be exhausted from the house, both to allow for fresh air and to maintain a high neutral plane. For this reason we need a planned-hole-high-in-the-house, but the air going out must come into the house from somewhere. If you carefully seal all the leaks in the house to m...
Yes -- if the cold-air input is uncontrolled. In fact, uncontrolled cold-air drafts are the reason for dryness in older houses. Damper control of the cold-air intake (not the hot-air exhaust) will allow you to maintain whatever level of humidity you want.If your furnace combustion air is provid...
It is harder to down-size an old gas furnace than an oil furnace, but it can be made to operate more efficiently.-- Increase the fan speed to draw more heat out of the furnace.-- Increase the "fan-on" time before and after operation to draw more heat out of the furnace.-- Install an electronic pi...
Open fireplaces are not heating systems. They have traditionally been built on an outer wall, creating sealing problems for air barriers and wasting lots of heat through the back of the chimney. Fireplaces should always be built on the inside walls -- if you build one at all. The problem w...
A combustion furnace or boiler (gas, oil, coal or wood) requires air to burn and air to maintain a proper draft in the chimney. In a leaky old house with the furnace in an open basement this is never al problem. As the house becomes better sealed, several problems can arise:-- An automatic v...
Joan from Armstrong, BC is having trouble adjusting the ventilation system in her new home to keep condensation off the windows. She told us the kind of system she has and said that it was required by the building code. Actually no specific system is required by any of the building codes. ...

Many years ago, because of the prairie enforcement of the gas code provision that you had to supply fresh air to a furnace, an inventor in Alberta began marketing the Hoyme damper. This is a motorized damper that closes off that combustion air duct from the outdoors that dumps cold air into ...
