OLD BASEBOARDS
Baseboard electric heaters are notorious for providing uneven heat -- cycling hot and cold -- with thermostats that are quite unreliable. Whether looking at them for the whole house or topping up the heat in difficult to reach corners of the house, most contractors see baseboar...
More and more people are asking for powerful kitchen range hoods or bathroom exhaust fans. The logic appears simple, increase the power of the exhaust fan and get rid of pollutants quicker.

One morning the oil furnace and boiler companies woke up to discover they were the Canadian bad guys -- everybody was condemning oil burning heating and the government was even paying people to scrap them.

Traditional furnace rooms are nothing more than a partition designed to hide an ugly furnace. They are neither sealed nor insulated, and they obtain combustion air from the house through door or wall grills of the open floor joist area.

The best way for air to move through a duct is to have a straight duct with a smooth inside wall and a round form will have the smallest surface area to cause the air to slow down. That straight smooth round duct is what is considered the benchmark for good ducting.

When you just can't get enough hot air to come out of that back bedroom floor grill and you have tried everything (like balancing your heating system), there is still hope.
We took a look at two fans on the market designed to boost that hot air.
The first, and the easiest to install and use is ...
In my experience, heating ducts that run through attics cause serious problems in snow country. Don't let a contractor talk you into it.
In warm climates it is common practice to run heating and air conditioning ducting through attic spaces simply because it is easy to do. Unfortunately this ...
The only research done that I have found on duct cleaning, outside of the duct cleaning companies themselves, has been by the Canada Mortgage and Housing Corporation -- EFFICIENCY OF RESIDENTIAL DUCT CLEANING -- CMHC Project No. : 93-2-001 January 1994.
Basically they found that when the ducts ...
In the spring of 2004, a young and dynamic company in Quebec got a new radiant heating cable out of the laboratory and onto the market that has almost no electromagnetic radiation. "FlexTherm" from Longueuil, Quebec came out with what they call their Green Cable.
