A heater system for heating a piece of equipment. The heater system includes a reversing valve, a refrigerant compressor fluidly coupled to the reversing valve, an evaporator fluidly coupled to the condenser and the reversing valve, a condenser fluidly coupled to the reversing valve, the evaporator, and the piece of equipment, and a controller. The controller is configured to cause the reversing valve to operate between a first mode and a second mode. In the first mode, the piece of equipment utilizes a refrigerant, circulating in a first direction and heated via the evaporator, to keep the piece of equipment within a desired temperature range, and in the second mode, the evaporator utilizes the refrigerant, circulating in a second direction opposite the first direction and heated via the piece of equipment, to defrost the evaporator.

Heater systems

An energy consumption controller may be communicatively coupled with a plurality of alternative energy sources and an engine. The controller may be configured to manage energy consumption from the alternative energy sources interconnected with the engine and to keep the engine within a desired temperature range. Within the desired temperature range, the engine will start and run at a full load more rapidly than if the engine cooled excessively. The controller may change the selected energy source as required, based on factors such as cost, engine maintenance and testing and/or imminent need of the engine.

Engine heater control system

A fluid heater is disclosed and which has a heater, pump, and a plurality of temperature sensors which are electrically coupled with first and second temperature controlled relays, and wherein the fluid heater is operable to maintain a source of fluid used by an object of interest within a predetermined temperature range and further, is operable under given temperature conditions to discontinue operation so as to protect the object of interest and the heater from becoming damaged through overheating of the fluid which is utilized by same.
