Budgeting the installation of a high efficiency gas boiler in Boston
I want to know if I should proceed here, or if I'm just wasting HVAC contractor's time in getting this re-quoted:
Last weekend, I started thinking about having a modulating/condensing boiler installed in Boston. I have forced hot water heating. I conservatively calculated my heat loss at 50k BTU, and read up on boilers. I was optimistic at first, seeing how boilers like the Viessman Vitodens 100 or a Triangle Tube Prestige 110 can be ordered for $3k over the Internet. (Of course, that is not what I want to do -- I want this installed by someone who has done one before.)
I was surprised to have a HVAC contractor quote the job at $12k for a fairly straight-forward direct venting setup - no indirect DHW tank, one zone. I'm not "cheap" but I just can't afford that right now. I was figuring about half this given the material cost and my expectation of labor costs (10 hours, 2 guys, guesstimating $150/hour per person = $300/hr total).
Should I bother getting additional quotes? Have other people in the Northeast been able to get this type of boiler installed for around $6k, or is my budget way off?
(If folks like jadnashua want to chime in, I've read through the old posts and see that you've gone through this in the past -- experience and thoughts are welcome!)
