Hatco PMG-100 Powermite Gas Booster Water Heater, 105,000 BTU, 24.8 kW Output, 4.75 Gal., Natural or LP Gas
A gas-fired booster that heats 241 gallons per hour through a 40°F rise to the 180°F sanitizing rinse, sized to sit near the dishmachine.
The Hatco PMG-100 Powermite gas booster water heater takes 105,000 BTU per hour of gas input and delivers 84,800 BTU per hour, equal to 24.8 kW. Its three tube type burners use primary and secondary air for consistent ignition. It has a finned tube copper heat exchanger and a 4.75-gallon stainless steel tank. Hatco designs it to fit under the dishtable near the dishwasher, cutting the heat loss of a remote heater. Natural gas is standard and propane is optional, so tell us the gas type and your elevation when you order.
Plan the vent run and gas line with a qualified installer before the heater arrives; installation must follow the National Fuel Gas Code or local codes.
Recovery is 321 GPH at a 30°F rise, 241 GPH at 40°F, 193 GPH at 50°F, 161 GPH at 60°F and 138 GPH at 70°F.
A stainless steel tank and finned tube copper heat exchanger, with stainless steel front and top and powder-coated sides and back.
A blended phosphate water treatment system and a shock absorber come standard, along with the pressure reducing valve and two temperature/pressure gauges.
A low-water cut-off, temperature/pressure relief valve and manual reset high limits protect the tank and heat exchanger.
Spark to light ignition with a standing pilot fires three tube type burners. Hatco factory presets the electronic temperature control at 190°F.
Match the GPH your dishmachine final rinse uses to your temperature rise. The PMG-100 heats 241 GPH from 140°F to 180°F (40°F rise) and 138 GPH from 110°F to 180°F (70°F rise).
Natural gas is standard; propane is an option. Natural gas needs 5" to 10.5" WC at the inlet, propane 11" to 13" WC.
Yes. The controls and forced draft run on 120V and use 3.0 amps (360 W). Hatco calls for a 120V, 15 amp supply.
It uses a forced draft system with a 4" vent pipe adapter, straight or 90°. Check with your local code authority or gas supplier before installing the vent.
Water over 3.0 grains of hardness per gallon must be softened first. A blended phosphate water treatment system is standard, but failure from liming or sediment is not covered by the warranty.
Hatco covers gas booster tanks for 1 year parts and labor plus 9 more years parts only; other parts carry Hatco's standard 18-month limited warranty. Register within 90 days of factory shipment to qualify for added coverage.
