    Mod Con Boiler vs Heat Pump – Nassau County, Long Island

    Dana, I understand you are proposing UFT-80w as primary heating, and mini-split heat pump as cooling and secondary heating. Question on energy consumption. Say post-insulation heating load to be 30,000 BTU/hr for design temp range of 55F (between +70F and +15F). For average seasonal temp...

    Mod Con Boiler vs Heat Pump – Nassau County, Long Island

    A follow-up on gas unit cost. $1.58/therm is based on Sept. 2016 billing (my first bill since moved in). I just found out the unit cost from Nov. 2015 thru March 2016 ranged from $0.91 to $1.20/therm. That makes it about $10.80/MMBTU vs $21/MMBTU for electric. I thought winter gas cost...

    Mod Con Boiler vs Heat Pump – Nassau County, Long Island

    Thanks. Lots of info to digest, especially on solar. Quick takeaway is heat pump has about 30% higher operating cost than gas condensing boiler using the efficiency and model units you assumed. But I can save a bit on upfront installation cost with heat pump because its 2 units in 1. Adding...

    Mod Con Boiler vs Heat Pump – Nassau County, Long Island

    BadgerBoiler, I have contacted a local supplier as NY_Rob suggested in his post, who can place an order for me, be shipped in a month, but does not stock any replacement parts. That makes an experienced contractor even more critical, not just for installation, but future servicing and repair...

    Hi Rob, If you can ask your contractor, it will be great. I am new to this forum so I am not sure what's the best way to exchange contacts privately. I just sent you a message. Thanks, Jerry
