Tests have shown that with a QW Damper thermostat 5kg of fuel will last 57% longer, increasing the burn time from 5.25hrs to 8.25hrs. That is, the thermostat automatically reduces or increases the air-flow proportional to the desired setpoint as needed to maintain the correct temperature. The QW does this by controlling the flow of air into the appliance by moving a flat damper plate at the end of the control arm relative to the air intake port of the appliance in response to variations of temperature at the sensor. The QW from Teddington Appliance Controls is a Thermostatically Controlled Damper Valve which regulates the temperature of a solid fuel system so that the system's temperature is maintained near a desired setpoint temperature, chosen by the user. Whilst this works, it is not the most economical or effective way to control the temperature. Shut the door halfway and back up rubbing your eyes because smoke is now filling the room. Typically, most solid fuel appliances are controlled by manually choking the air supply. Make a careful cradle with kindling and copious amounts of newspaper. Trials have clearly demonstrated that by controlling the air supply to maintain an even temperature, any solid-fuel stove or range can reduce it's CO2 footprint and fuel consumption, optimising efficiency. Gain up to 55% increased economy, simply by managing the burn rate of the fuel. In this way, your firebox will be adequately heated, making your firewood burn more efficiently. Close the door of your fireplace and keep the door close from 6 to 40 hours, depending on the size of your firebox. Reduce the fuel consumption of any solid-fuel stove or range. fire officials about restrictions and installation inspection requirements in your area. Heat your flue gas and let it reach about 700 degrees.OPEN AIR CONTROL (AND DAMPER WHEN FITTED) BEFORE OPENING FIRING DOOR. Works with Coal, Antracite, Wood - or any solid fuel. DO NOT STORE FUEL WITHIN HEATER INSTALLATION CLEARANCES.QW makes your solid-fuel last 57% longer.
