I installed a mixing valve in my grandparents house. The domestic hot water is heated in the boiler i believe it has a small reserve tank inside. The valve is located a few feet above the boiler with no thermal trap. My problem is that the hot water coming out at the fixtures only comes out for a short period. Much shorter than when there was no mixing valve. will a thermal trap fix this problem?
