Reposting as new thread, instead of on an old one. We're in PA - about 25 miles North of Philly. We've got a 10 year old Weil Mclain boiler that is way oversized - 240K. The crooks who sold/installed it to the previous owner put in a full 2 gallon nozzle! It was there when we bought 4.5 years ago. We can finally get gas now and I've placed the order w/ PECO - finally we'll have a gas cooktop.
I've done several detailed heat loss analysis workups and I get about 82000, while trying to be at least a bit conservative. I'm not factoring in heating water in this at all - it's strictly a heat loss analysis of the structure (build 1875 - mostly brick, except for an addition put on the back about 40 years ago). We did a lot of air sealing and insulating this year, starting in the spring (we did a full energy audit w/ blower test). This past summer was much more comfortable than prior years. Total sq footage is 2950, 4 levels and 3 zones (zone a is front of house, zone b is middle of house and zone c is rear - only 2 floors not 4). Rear of house also has very new fujitsu split heat pumps, that kept it comfortable solo (that zone was drained out for last 18 months).
I'm trying to get some quotes from local guys here and would appreciate some basic figures, parts and labor separately - if we go with the following:
- Carlin EZ conversion
- Outdoor reset
- (optional) indirect water heater, perhaps a 40 or 50 Amtrol? They seem to be less expensive and ppl say good things about them (current boiler doesn't seem to have integrated connections for this so if we do go w/ one vs. a standalone gas water heater we'd need a small separate circuit built for that). There is plenty of room next to the boiler.
Also - does anyone have really good figures on recovery value for an indirect water heater vs a high recovery 50 gallon stand-alone gas water heater? We can get a Rheem 42vr50-40f for under $600 delivered.
That aside, if we did go with simply "a new gas boiler" that can be directly vented (to avoid lining chimney), any cost estimates? (there is an external wall in basement for direct venting).
One last thing ... let's say that I kept the boiler as is - and downsized the nozzle to put out say 100K btu (acceptable nozzles are listed on the side of the boiler and this falls into the range) - how much oil might I save if I did NOT mess with anything at all for the boiler?
Thanks very much in advance, for your assistance!
