Radiant heating system

A method of distributing a heat transfer medium to a heat distribution system, the method comprising:

• activating a heat source under control of a thermostat;
• in a first manifold, mixing a first heat transfer medium received from the heat source with a second heat transfer medium received from a heat distribution system;
• forcing the mixed heat transfer medium from the first manifold to a second manifold using a circulator, wherein the circulator is mounted below the first manifold and below the second manifold,
• receiving the forced heat transfer medium from the circulator at the second manifold;
• distributing a first portion of the received heat transfer medium to the heat distribution system from the second manifold;
• and
• distributing a second portion of the received heat transfer medium to the heat source from the second manifold.

A method of installing a radiant heating system, the method comprising:

• mounting a first manifold in a mounting location, the first manifold comprising a first body;
• an outlet port mounted to the first body;
• a first heat distribution port mounted to the first body;
• and
• a supply port mounted to the first body;
• mounting a second manifold in the mounting location, the second manifold comprising
• a second body;
• an inlet port mounted to the second body;
• a second heat distribution port mounted to the second body;
• and
• a return port mounted to the second body;
• connecting a circulator between the outlet port of the first manifold and the inlet port of the second manifold, the circulator adapted to force the heat transfer medium from the first manifold to the second manifold;
• connecting a heat source between the return port of the second manifold and the supply port of the first manifold, the heat source adapted to transfer heat to the heat transfer medium;
• and
• connecting a heat distribution system between the first heat distribution port of the first manifold and the second heat distribution port of the second manifold.
