THE HARDY OUTSIDE WOOD FIRED HYDRONIC HEATER
How does an outside heater heat my home?
The Hardy outside wood fired hydronic heater is designed to save the most energy and
provide the most comfortable heating available. It heats your home by heating a
stainless steel tank filled with water, which surrounds the firebox of the outside heater.
The heater is a non pressurized boiler with an atmospheric vent. This hot water is then
circulated through underground hot water pipes to a water coil inside your existing
central duct system. The Hardy Heater can be connected to any existing hydronic
heating system that operates at 170 degrees Fahrenheit or less.
How does THE HARDY heat water for household use?
A plate heat exchanger (optional) is installed in the hot water circulator line. When you
open a hot water faucet inside your home, the cold water passes through the other
side of the heat exchanger and the water going to your hot water heater is preheated.
The only additional energy required is maintaining the hot water temperature. The
plate heat exchangers can be used for pools, dairies and other domestic hot water
needs.
How do the Thermostat Controls work?
The only visible addition to the heating system inside your home is the thermostat
which is located next to your existing thermostat. The two thermostats are installed so
that if the outside wood burning heater is not in operation, your existing unit can be
used to maintain your household temperature. The wall thermostat which regulates the
heat from the outside heater turns the blower on inside your central unit to force air
across the hot coil. This forces hot air into your central duct system. The outside
heater has a Process Control Module which senses the water temperature of the unit.
This module cycles the heater on and off in order to maintain a preset water
temperature.
Where should the Hardy Heater be located?
The outside unit should be located at least 10 feet from your home, other structures or
any other combustible materials so that all fire danger is removed. The unit may be
installed as much as 100 feet away. If the unit is located more than 100 feet away, you
may experience some heat loss on the water supplying your water heater. Locate the
outside wood burning heater where it will be convenient for refueling. All water and
power lines are installed underground between the house and the outside wood
heater. Additionally refer to the Best Burn Practices section in this manual.
