THE HARDY OUTSIDE WOOD-FIRED HYDRONIC HEATER
How does The Hardy work?
The Hardy Outside Wood-Fired Hydronic heater is designed to save the most energy
and provide the most comfortable heating available. It heats your building by heating a
stainless steel tank filled with water, which surrounds the firebox of the outside heater.
The heater is basically 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 Hydronic Heater can be connected to any
existing hydronic heating system that operates at 180 degrees or less.
How do the thermostat controls work?
The only visible addition to the heating system inside the building is a thermostat which
is located near the existing thermostat. The two thermostats are installed so that if the
outside wood heater is not in operation, your existing unit will automatically take over to
maintain the building temperature. The wall thermostat which regulates the heat from
the outside heater performs two functions; when it senses the need for heat, it turns
the water pump on to circulate the hot water through the coil and also 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 hot water thermostat which senses the
water temperature of the unit. If the water is not as hot as the thermostat setting then
the combustion air intake is automatically opened and remains open until such
temperature is attained.
What are acceptable installations?
These units are designed and approved for installation in light commercial
environments. In accordance to Federal New Source Performance Standards (NSPS)
for New Residential Hydronic Heaters these units are not for sale, installation, or
operation in a residential application.
Where should The Hardy be located?
The outside unit should be located at least 10 feet from the building be served so that
all fire danger is removed. The unit may be installed as much as 100 feet away and still
heat the building . If the unit is located more than 100 feet away, you may experience
some heat loss and require larger supply and return lines to maintain proper flow rates.
Locate the heater where it will be convenient for refueling and wood storage. All water
and power lines are installed underground between the building and the heater.
