ABSTRACT:
In a three-way, variable position, automatically controlled diverting valve that is provided in the return line to the boiler of a hydronic heating system between the heating loop return and the boiler return, the valve having its input from the heating loop return, its through output to the boiler return and its diverted output to the heating loop supply, so that the valve diverts some of the cooler return water to the boiler hot supply water, diluting the supply water to reduce the temperature of supply water that feeds the heating loop, a method and means of adapting the diverting valve so that the valve cannot be positioned so that the diverted water flow therefrom is closed, including a stop plug inserted into a housing of the valve that reduces the range of said variable positioning.
