The Vermont Comprehensive Energy Plan, CEP, has a goal to install about 35,000 air source heat pumps, ASHPs, by 2025, and projects:
About 63% of building space heating* and domestic hot water, DHW, from renewable electricity (wind, solar, hydro, biomass, etc.)
About 34% of building space heating and DHW, from wood burning (cordwood/pellet) and bio liquids.
About 3% of building space heating and DHW, from fossil fuels burning.

Ground source heat pump systems, GSHPs, are becoming the preferred way to electrically heat and cool a house, an apartment building, or a university campus, or a medical center, etc. This is especially the case in northern European countries, such as The Netherlands, Denmark, Germany, Norway and Sweden. See Appendix.
The big plus for nearby people (and flora and fauna, and forests), due to not burning trees and fossil fuels, will be no…Continue

This article explains in detail how the efficiencies of wood stoves are calculated using the higher heating value or lower heating value of the fuel. In case of condensing wood stoves, the higher heating value must be used.
The US uses higher heating value, HHV, as the basis for calculating efficiency, Europe uses lower heating value, LHV.
This leads to European stoves having calculated efficiencies greater than US stoves, which deceives lay people in the US,…Continue
