> What is the benefit of storing the heat of wood pellet or gas? Can't you just use those on demand? Burners scale badly to lower power. Also, automatic pellet feeders are prone to breaking down, which you absolutely do not want to happen when it's -15C on the outside. Thus a thermal buffer is needed. > Also hot firebricks was my proposed solution. Water has comparatively low energy density Water actually has about four times more energy density than bricks. > I understand that there isn't a ton of sun in winter months but maybe you could over provision your PV Prohibitevily expensive in both money and area needed > store summer or fall solar energy Impossible. Where and how would you store enough?
