Claims
- 1. Apparatus for efficiently utilizing heat energy from an auxiliary source that includes
- a flow line for circulating a heat transfer fluid through a loop,
- a pump connected into said flow line for moving said fluid through the loop in a given direction,
- first, second and third automatic three way diverting control valves connected in series in said flow line in the direction of flow and each of said valves being arranged to pass fluid circulating in said loop directly between an inlet connection and an outlet connection when said valve is energized whereby fluid passing through the valve is not diverted from said flow line,
- said first and second valves in the series being arranged to pass fluid between said inlet connection and a bypass connection when said first and second valves are deenergized whereby fluid moving in the line is diverted from the flow line,
- said third valve in the series being arranged to pass fluid between a bypass connection and said outlet connection when the valve is deenergized whereby fluid previously diverted from the line is returned to the loop,
- an auxiliary heating unit connected in series flow relation between the bypass connection of the first valve and the inlet of the second valve,
- a primary heating unit connected in series flow relation between the bypass connections of the second and third valves,
- a fluid storage unit connected in series flow relation between the outlet connection of the second valve and the bypass connection of the third valve, and
- control means for independently energizing each of said valves so that a selected one of said units is placed in fluid flow communication with either one of the remaining two units whereby fluid can be exchanged between any two of the three units.
- 2. The apparatus of claim 1 wherein said primary heating unit further includes a hydronic loop through which said heat transfer fluid is passed.
- 3. The apparatus of claim 1 that further includes heat sensing means for determining the temperature of the heat transfer fluid in the auxiliary heater and the storage tank and automatically energizing the valves in response thereto.
