On another forum I stumbled across this http://www.hydro-to-heat-convertor.com/index.html and would like your opinion. I have a very efficient home that at peak requires 21k btu. Most boilers are to big but this seems hopeful. I already have solar dhw and a PV array. I am heating about 2600 sq ft with about 2 1/2 cords of wood. Currently I use a Woodstock fireview which I love.
Thx,
Jim
