Looking for Advice on new boiler system
Hello all. New to the forums. I've been researching boilers for the last couple of months. I had some gas lines ran to the home to switch from oil heat to gas heat. I have to make a decision this year or I have to pay for the credit UGI gave me for the line install.
I've been looking at all sorts of boiler types, and I am having a hard time making up my mind on some things... I definitely want a direct vent. By the time I get a chimney vent with the lining of the chimney, it'll cost about the same or even more then just getting a high efficiency boiler.
I was researching condensing combo boilers but I don't like the idea of how I have to drain out the condensation, and being in the basement I would need a pump to pump it up and out. Then I have to worry about the drain pipe freezing. My least likely option, but the prices are cheap and I could sell my hot water heater to get back even more of my money.
Are there non condensing combo boilers? I found a NRCB180DV 180,000 BTU Combi Boiler and no where in the description does it mention being a condensing boiler. But it looks small compared to a heat only boiler. Are they a good option? I would hope that I could take a shower and not experience cold water if the heating system had to kick on lol.
The other option is just getting a heat only HE gas boiler. I had there boilers I was looking at:
PVG3, 52,000 BTU Output High Efficiency Cast Iron Boiler
GV90+3 56,000 BTU Output High Efficiency Gas Boiler
GV90+4 84,000 BTU High Efficiency Gas Boiler
I really don't think I would need 84k BTUs with the Well Mclain. I live in one of my units of a multi unit home, and this apartment is only around 650-700 SQ FT minus the basement. I think 52-56k would be enough for such a small home. The current system is 120k but it used to supply more units before I cut those lines off.
I really like the idea of a combo boiler that doesn't condensate. But again, not sure if the one I posted condensates or not, if it doesn't then I think I might go with that one. But with domestic hot water heating, how many BTUs should you have to be able to take a shower while the boiler also heats your heating water? I thought 180k would be more then enough but I saw some reviews about combo boilers not being good for more then 1 hot water line at a time. Suggestions? Thanks!
