I'm looking to replace my circa 1960's oil boiler. I have a old victorian home (about 1800sf) in New England and am looking to replace the boiler (before it dies) with something more efficient. I have the cast iron radiators, which I will probably continue to use. I also have a gas line ready and waiting for a gas boiler if I go that route. I am also looking into pellet stove boilers, etc, as I would like the most cost effective solution (efficiency is key). Tired of the $600/month oil bills! :) Anyone who has done this or plumbers out there, looking for your advice. Thanks in advance!
Natural gas (NOT propane!) is extremely cheap. Fracking is unfortunately here to stay, but it's making gas very,very affordable even in the long run. Get rid of that oil burner ASAP. Remember that pellet stoves are not covered under federal energy tax breaks. This is a major financial factor in making your decision since the tax breaks are significant.
I would go with a modulating, condensing, gas boiler. They can run up around 98% efficient. It only required minor maintenance every couple years. Just get multiple quotes now before it dies and you are good. FYI, $600 a month is insane. That new boiler would pay itself off in a couple years.
i do no longer see any authentic problems. the recent oil fired boiler will probable have a circulating pump geared up. If no longer, one would be needed interior the pass pipework. you will possibly be able to might desire to line the flue and in wonderful condition an approved terminal. you will of direction want an oil tank, bund and linked pipework. no remember if that's suited you are able to bury the tank at present.
I would be inclined to go along the gas route and also replace the old cast radiators as the modern steel ones contain a lot less water. Less water = less gas to heat them up+ less water means they heat up faster which means you get warm quicker and more importantly 'cheaper'.
i would fit a condensing combi boiler. you mention you have cast iron radiators. you may also have an old one pipe system. if you want to keep the radiators cos they suit your decor i would have your system changed to a two pipe system which will make the system more efficient.
