Currently have a propane forced air 92% 80,000 btu furnace heating/cooling our 2200sq ft story 1/2 colonial. This is in central ohio so big fluxuations in temps. Burned about 1,000 gallons of propane last year, which also included a fireplace we use to help heat the large kitchen because it's a very cold room and is lacking in the duct department. This issues will be resolved regardless.
Currently getting ready to renovate the kitchen, blow-in insulation to the exterior walls, and new siding installed this summer. We're laying about 400 sq ft of 100 year old t&g oak flooring in the kitchen and were wanting to heat it. After finding this isn't that easy to do with nail down flooring, this has evolved into thinking I may want to switch the entire first floor over to radiant heating. About half of the first floor is crawl space, the other half basement. Am I crazy to think about installing a fuel-oil hot water system for the downstairs and keep the propane just for upstairs? Obviuosly need to keep the air system for cooling and my wife doesn't want visable radiators which is why I was planning to keep the forced air heat upstairs.
Also, can this boiler typically be used for domestic hot water as well? Currently have electric hot water heater (electric is about .10/kwh). Propane averaged me $1.36/gallon last year. Diesel is probably about the same price. Who knows what will happen next winter:)
Also, do the new boilers have to be vented? I tore out all the exhaust from the basement during renovation of that section of the house.
How would you recommend finding a qualified installer? Very little hyrdonic heat in this area. How much should a fairly simple 1 zone system run?
I don't think your crazy to want to do it. Radiant, in my opinion, is the best heat there is. You could run a system off a boiler, or even a hot water tank, if it is allowed in your area. With a boiler, you can use a Indirect water heater and get rid of your electric one. Since you already have propane, you could use to fuel your boiler. If the flooring isn't down yet, you could go with a sandwich (over the floor) system- or you could use underfloor stapleup. It might not be easy underfloor if you have a million nails protruding underneath. Cost really varies depending which installation method you choose and what type of controls you want.
