Gas heating system for a parts washing machine, and to the method of converting an electric parts washing machine to a gas parts washing machine

A parts washing machine for cleaning a part, said parts washing machine comprising:

• a parts washing machine housing having a zone, said zone having a reservoir and a dispenser, said reservoir having a first heater hole and a second heater hole, and is adapted to contain a medium that is selectably dispensed from said reservoir within said zone;
• and
• a heating assembly having:
• a tankless heater, said tankless heater configured to heat water;
• a heat exchanger, said heat exchanger being received in said reservoir;
• and
• plumbing comprising a main circulation loop, a main circulation loop pump, a zone loop, and a zone loop pump, said main circulation loop being outside of said reservoir and said zone loop interconnecting said main circulation loop with said heat exchanger through said first heater hole and said second heater hole.

A method of converting an electric heated parts washing machine to a gas heated parts washing machine, and then using the gas heated parts washing machine, the method comprising the steps:

• providing a parts washing machine housing having a zone, said zone having a reservoir and a dispenser, said reservoir having a first heater hole and a second heater hole, the parts washing machine containing an electric heater associated with the first heater hole, and is adapted to contain a medium that is selectably dispensed within the zone from the reservoir;
• removing the electric heater from the reservoir;
• providing a heat assembly with a tankless heater outside of the reservoir, and with plumbing having a zone loop, a first adapter, a second adapter, a heat exchanger, a sensor and a controller;
• placing the heat exchanger within the reservoir;
• fastening the first adapter to the washing machine at the first heater hole, fastening the second adapter to the washing machine at the second heater hole, and connecting the zone loop to the first adapter and the second adapter;
• and
• operating the zone loop when the sensor senses that temperature within the reservoir falls below a certain level to provide hot water to the heat exchanger via the zone loop.
