They sure made it look easy. I'm pretty sure that plumbing mains had to be disconnected. Copper pipe might flex 1" upwards, but I'm pretty sure that cast iron drain pipes wouldn't budge. I'd find my...

This is one concern of mine as well. The tighter I make my basement, the closer I get to having to add fresh air intakes for the furnace, water heater, and clothes dryer. I don't want to just let...

Sealing the basement

Well, I am currently in the sealing and insulating phase of energy-proofing this old house. I figure the best place to start is the basement. There are quite a few projects down there that can give...

That's usually a sign that the fire is burning too hot with not enough air, OR that too much air is being fed to a cool fire. You said that it had a combustion air fan, correct? Is there a damper or...

What is the problem with the combustion? Are all the flames going up the flue, or is there a lot of smoke coming from the chimney?

We need specifics! :)

I think the trick is to tune to system and changeover temp to always use the cheaper source of heat. That is one advantage of a dual-fuel system. As mentioned before, at my gas and electric rates the...
