We have a boiler and some resistive heating. We are going with whole house (6500 sqft total) heat pump system. Ends up being several large commercial Fujitsu units that are efficient down to -20F (Colorado weather). We expect to dramatically cut our energy consumption with this move and be totally off natural gas. Combined with the solar and battery system we are getting we should be completely energy independent and net producing electricity which is cool :)
