I have a leak in my old peerless and was told need to replace. It is in a small space in a closed small area in my garage. I have 3 heating zones in my home and they are the zone valves are all located under the house in the crawl space.... Dumb!! I have 2 oil tanks in my garage as well and one person said because they at least 25 years old to change them too because they showed me that you can see a darker area on the tanks a nod this could very well mean that they are rusting from the inside out and could be a problem if they start to leak. Never was told this by my own company who was in that garage many times last winter to replace a circulator and a expansion tank. Someone came and said get propane in the long run it is cheaper. 8900 installed for a visas an is not great for me right now and I was looking at a badarus unit with a becket or riello burner ? I hVe no idea where to turn for good advice. And really am trying to educate myself. How do I know if I also need to replace the two oil tanks that have been garaged their whole life? What do I look for because i don't want a problem but I really can't afford the extra expense. Also they mentioned a cold start unit can be turned on and off in the summer so I do not have to let it run just to make hot water to save money on the oil. Does the badarus come in a cold start model? Thanks for all this help and advice!

how do you heat you domestic hot water?
buderus make an excellent unit.
they have devices taht can measure how thick the metal is on your tanks. at 25 years old, i would not worry about them.
heating oil around here is selling for 167 per gallon while propane is double that.
a buderus wall hung gas boiler will run about 10% more efficient than an oil fired unit.
oil will require a yearly tune up while gas needs to be cleaned about every 3 years.
oil will need a chimney although it can be side wall vented.
gas can have a PVC flue and make up air.
if it were me, i would stick with oil..
look for big rebates. around here there is a 1700 dollar rebate for oil.
lastly.. just about all heating equipment come as 'cold start'...

i agree with packy stick with oil, propane will cost you both arms and legs, i have a friend here in southern michigan who heats his 2,000 sq ft ranch style home with propane, costs him average $1,200 per month!
