I wish to replace my 1967 weil-mclain E-7 series 2 boiler. input capacity is 201,000 btu and output capacity is 167,000 btu. house is 1.5 stories 2,200 square feet with moderate insulation, new windows and full basement in Philadelphia, PA. Before I contact plumbers, etc. can I get input on sizing? I am thinking since new gas boilers are so much more efficient I will be able to go with a boiler with alot lower btus.
