## Abstract

A boiler regulation system for diverting energy from a boiler to hot water production having a housing with a thermostat dial, a sensor connection, and a plurality of connections on the housing; a step down transformer, a first general-purpose relay coil, a close-on-rise thermostat, and a first normally closed contact relay corresponding to a heating zone valve/pump each in the housing; wherein when the close-on-rise thermostat senses a rise in temperature when hot water is in demand the close-on-rise thermostat closes sending a first signal to the first general-purpose relay coil and the first general-purpose relay coil energizes causing the first normally closed contact relay to open, discontinuing power to the heating zone valve/pump thereby enabling boiler energy to be used for hot water.

## Claims

### Claim 1

A boiler regulation system (100) for diverting energy from a boiler to hot water production, said boiler regulation system (100) comprising:
(a) a housing (110);
(b) a thermostat dial (120), a sensor connection (130), and a plurality of connections (140) each disposed on the housing (110), the connections (140) each comprise an in port and an out port wherein the in port is operatively connected a close-on-rise thermostat (250) and the out port is operatively connected to a heating zone valve/pump, the sensor connection (130) is operatively connected to a domestic hot water pipe;
(c) a step down transformer (205), a first general-purpose relay coil (210), the close-on-rise thermostat (250), and a first normally closed contact relay (310) corresponding to a heating zone valve/pump each disposed in the housing (110);
wherein when the close-on-rise thermostat (250) senses a rise in temperature when hot water is in demand the close-on-rise thermostat (250) closes sending a first signal to the first general-purpose relay coil (210) and the first general-purpose relay coil (210) energizes causing the first normally closed contact relay (310) to open, discontinuing power to the heating zone valve/pump thereby enabling boiler energy to be used for hot water;
wherein when the close-on-rise thermostat (250) senses a drop in temperature when hot water is not in demand the close-on-rise thermostat (250) opens and the first generally-purpose relay coil (210) de-energizes allowing the first normally closed contact relay (310) to close and power to resume to the heating zone valve/pump.

### Claim 2 (depends on 1)

The system (100) of claim 1 further comprising a vent (105) disposed on the housing (110).

### Claim 3 (depends on 1)

The system (100) of claim 1, wherein the step down transformer (205) is a 120 v/24 v transformer.

### Claim 4 (depends on 1)

The system (100) of claim 1 further comprising a second general-purpose relay coil (220) disposed in the housing (110) and a second normally closed contact relay (320) corresponding to a heating zone valve/pump disposed in the housing (110), when the close-on-rise thermostat (250) senses a rise in temperature when hot water is in demand the close-on-rise thermostat (250) closes sending a first signal to both the first general-purpose relay coil (210) and the second general-purpose relay coil (220) and the general-purpose relay coils (210, 220) energize causing both the normally closed contact relays (310, 320) to open, discontinuing power to both the heating zone valves/pumps thereby enabling boiler energy to be used for hot water; when the close-on-rise thermostat (250) senses a drop in temperature when hot water is not in demand the close-on-rise thermostat (250) opens and the generally-purpose relay coils (210, 220) de-energize allowing the normally closed contact relays (310, 320) to close and power to resume to the heating zone valves/pumps.

### Claim 5 (depends on 1)

The system (100) of claim 1 further comprising an indicator light (280) disposed on the housing (110), the indicator light (280) is operatively connected to a normally open contact relay (340) disposed in the housing (110), wherein when the coil (210) is energized the coil (210) sends a second signal to the normally open contact relay (340), supplying power for the indicator light (280) and when the coil (210) is de-energized power stops to the indicator light (280).
