90%+ HYDRONIC HEATING SYSTEM
The QVM 9 provides 2 different heating functions that operate independently from the same water heater. One
mode provides space heating water to heat the home. The other mode provides a continuous circuit of hot
water for domestic use e.g., bath, laundry, etc. Both circuits are separate and operate at different temperature
ranges.
The space-heating water is controlled by the FR-5 thermostat. A special thermostat has been provided that
enables the user to either set the room temperature required or set the heating water temperature. In some
cases this thermostat may not be suitable for multi-system applications(The installing contractor will make this
determination and install suitable alternative controls).
The domestic hot-water is controlled by the user. Because the QVM 9 is a multi-purpose design, it can
provide hot water on demand. There is no storage tank to hold hot water, when there is no use for it. The
QVM 9 will only produce hot water when you use it : instantaneously. The modulating gas burner allows water to
heat up evenly as it is being used. The QVM 9 will continue to heat the water until the source or sources are shut
off. This on-demand-use also helps to prevent water being held in the water heater for long periods of time.
IMPORTANT :
A thermostatic mixing valve should be installed on the domestic water supply pipe to control the supply water
temperature and prevent any possibility of scalding.
The QVM 9 prioritizes domestic hot water over space-heating water and will immediately stop producing
space-heating water the moment a hot water faucet or valve is opened anywhere in the home. Once the faucet
or valve has been turned off, the water heater will return to the home-heating function again.
The QVM 9 is designed with a special sealed-combustion venting process. Both sides of the combustion
process(inlet oxygen and outlet carbon monoxide) are isolated from each other and are totally sealed-off from
the air supply within the home. Infiltration, is reduced by as much as 90% making the QVM 9 one of the safest,
most comfortable and clean-burning water heater in the world.
