Solar evacuated tube collector heating house in subzero weather
This is my solar evacuated tube collector. I use this to heat in the daytime and I have plastic tubing in the basement floor of the house that stores some heat in the floor. Also, copper pipes running to baseboard radiators throughout the house for the system. I have an oil furnace that is currently not connected to the chimney unless for emergency. During normal heating days(when the outside temperature is not below zero)the solar evacuated tube system heats enough even on cloudy days, so that I can start the wood stove at about 5 to 7 p.m. and put the final load of wood in at about 10 or 11 p.m. and then repeat the next afternoon the same. It cuts down on the amount of wood burned and cost is maximum of about 760 dollars per season. I changed the way the heat exchanger is connected so now it transfers more heat into the house. The inlet and outlet for the solar evacuated tube collector is now at the ends of the heat exchanger and the inlet and outlet for the house heating system is now at the sides of the heat exchanger.
