The thermal-expansion tank for domestic water heaters, sized right, is the only logical answer to the growing problem of thermal expansion in water heaters protected by BFP, check valves or pressure- reducing valves. A simple installation to the supply side on the water heater, this small tank will eliminate the dangerous condition so that the relief valve will not open during normal heating cycles.
