System and method for creating multizones from a single zone heating system

A multizone conversion system configured for converting a single zone into a plurality of zones, wherein the multizone conversion system comprises:

• an input device configured to attach between a hot water pipe and a first end of a heating element, wherein the input device comprises an RF circuit, a battery compartment with one or more batteries, and a switching valve;
• a bypass pipe configured to attach on a first end to the switching valve of the input device;
• an output device configured to attach on a first side to a second end of the heating element and a second end of the bypass pipe and also configured to attach on a second side to a hot water pipe;
• and
• a thermostat located in each room within a single zone heating system, wherein the thermostat comprises a temperature sensing device, temperature setting controls, an RF circuit and a display, wherein the thermostat is configured to control the input device located in the same room by wireless communication.

A method of converting a single zone system into a multizone system, wherein the method comprises the acts of:

• retrofitting an existing heating element in at least a first and a second room by adding an input device at one end of the heating element, the input device including one input proximate a first end, and two outputs proximate a second end, said input device configured for receiving an RF signal from a thermostat for causing said input device to fluidly couple one of said two outputs to said input, the input device coupled to an existing hot water pipe at said input on said first end and to the heating element on one of said outputs on said second end;
• installing a bypass pipe, coupled to the other of said two outputs of said input device on the second end, for generally providing a hot water path parallel to the heating element;
• installing an output device, the output device coupled proximate a first end to the bypass pipe and the heating element and coupled proximate a second end to an existing hot water pipe;
• installing a central thermostat in the first room, wherein the central thermostat comprises a temperature sensing device, temperature setting controls and an RF circuit, the RF circuit for providing the input device RF control signal and for receiving RF signals from peripheral thermostats, said central thermostat configured for providing the input device RF control signal for the input device controlling heat in said first room, and responsive to said temperature sensing device in said central thermostat and to an RF signal from one or more peripheral thermostats, for providing a signal to said boiler causing said boiler to provide hot water to said single zone heating system;
• and
• installing at least one peripheral thermostat in the second room, wherein the peripheral thermostat comprises a temperature sensing device, temperature setting controls and an RF circuit, the RF circuit configured for providing the input device RF control signal and for providing an RF signal to said central thermostat indicating heat is required in an area adjacent said peripheral thermostat.
