I have been getting quotes on a new LP Forced air system. My house currently has an ancient boiler system, so that means no existing duct work. The house is open and 1800 sq feet of living area. One of the contractors suggested electric radiant heat installed from the crawl under the flooring with individual room thermostats. Everything he says makes since since it is very hard and expensive to heat. I have replaced the windows and insulated as best I can. The installation of this is much less than the ductwork and furnace installation. But I am concerned about the electric part in the long run. Does anyone have good/bad experience with this type of retrofit heat?
I would replace your "ancient" boiler with a new high efficiency one. Besides already having all the piping there, hot water heat is way more comfortable than forced air. You could also do radiant with the hot water. Electric is very expensive to run!!!!!! What part of the country are you in?
I live in Indiana. LP is going sky high. I did ask re: new boiler but when they found out all of the problems with the existing registers and piping both contract. said new installation would be necessary. They would have to tear out existing and replace. My old system did work it was just so expensive. I have checked out a few sites regarding radiant heat. It all sounds very positive and it would appear that it would be a nice fix for my house. But as you said ELECTRIC can be very expensive. The sites indicate that they use low voltage and because they radiate heat into objects, one can keep the thermost 2-3 degrees lower than a forced air system. (but they are trying to promote their product)
I still think a new energy efficient boiler would be the way to go. You can still do underfloor radiant. And yes, it is said you can keep the thermostat a little lower. Unless your electric is about .03 cents a Kw/H, it would probably be cheaper for propane. What is your propanr price??
Propane is currently 1.50 but Last year during the cold months it got up as high as 1.89 gallon. The local papers are saying expect 5-7% increase over last season. Electricity is around .07 cents Kw. Perhaps I will call a few others and find someone interested in installing new pipe and registers. Two of the three were anxious to install LP forced air systems and advised against the new installation. I must say I agree with the guy who wanted to quote the radiant that LP forced air wouldn't be very efficient for my house. Maybe he wouldn't mind the installation of the copper etc. I am just surprised at how many people just want the easy way out whether it is good for the customer or not. I try to do most everything myself, but this one is a little out of reach for me. Thank you for your advice!
