ABSTRACT:
A heat exchanger which is adapted to an existing water tank to allow it to be heated or cooled using a hot or cold toxic or non-toxic liquid. Solar collectors and heat pumps can provide hot or cold liquids. To transfer this heat cheaply and economically to an existing hot or cold, water tank requires a simple efficient heat exchange, which can be easily adapted to the existing tank. The invention recited fills this need by simply screwing into the existing hot or cold, water tank and allow heat or cold to be added or extracted via a simple fluid loop, which is single wall isolated for non-toxic heat exchange fluids and double wall isolated for toxic heat exchange fluids.
