In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
My plumber told me that my 1000 square foot house doesnt need more than 30000 BTU. My last boiler was a lot more. He told me he did a heat loss calc and it came to 20000 BTU. I spoke to other plumbers and they all say I need 100000 BTU. By the way I am only heating the house with this boiler, nothing else.
