Biomass boiler for Climate Zone 5a, CT
I am hopeful that I am getting to the final stages of planning my HVAC system. To recap: The decision has been made to go all electric with a PV array to be added in the future to offset cost of operation. My home is 1400 sq ft, 15.7 ACH 50, but will be getting new Alpen double pane casement windows and loads of new insulation in the attic and rim joists.
In addition to the ASHP or AWHP (of the two, I am leaning toward a Chiltrix AWHP), I found in my notes “pellet boiler.” After additional research, I found that biomass boilers have similar start-up costs, lower running costs, can run at lower temps than HPs, release little to no CO2 into the environment (unlike HPs), can heat DHW and radiant panels, are quieter than HPs, run off of solar (if desired) and have great rebates for every NE state but mine.
Can anyone offer advice about this system, or as it compares to the AWHP?
