system cost

Hey all, I'm looking into installing either a tarm or econoburn boiler with 600 gallons of storage in my new house. I've gotten a price from a local mechanical contractor (who I work with a great deal as an architect) and the system is running in the $18k range before boiler purchase. I've already run all of the radiant tubing for two floors and the lines to the second floor (for a couple of pieces of baseboard for "radiant dump" as he called it) so there is no manhours for them on those items, they'd simply be setting up the boiler, tanks, controls and tuning the system. To me, the price seems high but having never done one of these systems before I really have no idea what to expect. Before we started, I had roughly expected $18k as the total cost, not the $28k we're currently looking at.

Please let me know what you think!

Thanks.

that's what I thought, I guess I need to get another price.

I'm ok with (but not thrilled about) the 18-20k range but 28k really makes me swallow hard. I'm just thankful that I've been able to build the house myself so that now I'm even considering a nut this large because my social and economic standing definitely are at odds with the price tag.

I'm building in Edgecomb which is in the wiscasset/boothbay/damariscotta area. I'm sure I could build one of the storage tanks but once it comes to plumbing and wiring I'm completely lost (those are the only two areas that I hired out). A local company has do-it-yourself storage tank kits for semi-do it yourselfers like me which I might try (waiting for a call back from them now) but I will not touch the controls side of things.
