plastic hot water tank with heat pump backup
Hi to all
My solar hot warer tank is maded from a 1000L PP plastic tank used for chemichal produts, inside I have 4 pieces of beer keg 50L each, 10cm insulation, the top of the tank is used for storing. The heat pump is a 24000btu R22 external unit with a direct heat in the tank with a copper coil 40m long, diam. 9.52mm. I made a test to heat the tank to 60 deg Celsius and it works fine, I must test this at low temperatures 0 deg C. From 40C to 46 in 1h I will made the controller for the heat pump with arduino, the solar controller is maded with arduino with data loged on xively I will put picture and links later, I'm to new hear. |
