Low Hot Water Pressure With a Hardy Furnace

Appliance Use

• Although the Hardy outdoor heater can produce up to 250,000 BTUs in heat per hour and comes with a stainless steel pump, the heater is not meant to supply hot water to several appliances at once. If you are using hot water simultaneously for different items, such as a shower, kitchen sink, dishwasher or washing machine, the water supply and pressure may drop. Reducing the number of appliances using hot water at the same time increases water pressure.

Cleaning

• Since the heater burns wood for fuel, the Hardy heater needs cleaning on a regular basis for proper performance. Turn off the heater and allow the unit thoroughly cool, and then open it and clean out the ash bin. Open the primary access door and use a long-handled chimney brush and clean out the damper blower passage opening and the blower wheel. Check the heater stack and clean it with the chimney brush removing creosote and ash build up. Restore power and give the heater several minutes to heat up and warm the water to the set thermostat temperature.

Voltage

• The minimum power supply necessary for the Hardy heater to heat and transfer water is 115 volts. If the connecting electrical outlet is not sufficient, the heater’s pump is not be able to provide the correct water pressure and supply. Contact an electrician if you are not sure about your voltage, if the outlet is less than 115 volts or reconnect the power cord into an outlet with higher voltage.

Distance

• The Hardy heater is designed to be installed within 10 to 100 feet away from the primary home. If the heater is installed farther than 100 feet away from the house, expect a loss of heat and water pressure. Note that all water lines are installed underground, so once the heater is installed, moving the unit is difficult and requires total reinstallation. Contact Hardy for assistance if this and other troubleshooting efforts do not resolve the problem.
