When to use a flue thermostat on a boiler?
A Flue Thermostat is used to sense when your boiler stove is running and then switch on your heating pump. This, among other things, stops the stove in effect becoming a radiator when it is not running which is what can happen if you just use a thermostat on the flow pipe coming from the stove.
Where is the probe on a flue thermostat?
A flue stat is a wonderful bit of kit and it can do the world of good for your solid fuel heating system. A flue stat has a probe which is mounted on or near the flue pipe of your stove.
What should the temperature of the flue gas be?
On boilers with risk of high probe temperatures above 300oC (common on over combusting boilers), the probe should be fitted underneath the flue, with a distance-plate in-between. Never place an unprotected probe directly in the flue-gases. See figure 1. Note: Firing with the damper open can give flue-gas temperatures of 600-700oC.
Can a probe be placed in a flue gas duct?
NEVER install probes or immersion directly in the flue gas duct. The thermostat probe must NEVER be exposed to temperatures greater than 300oC. At FIRST firing, check the temperature of the probe by checking for the “clicking noise”. Turn the thermostat knob back and forth when the boiler operates at full power.
When does the flue thermostat start the boiler?
The flue thermostat starts the pump as soon as the temperature of the smoke pipe rises to a predetermined level, after firing starts. In wood-fired boilers with self-circulation valves, it pre- vents cold water cooling the bottom of the boiler when firing starts.
What should the thermostat be on a Goldbird boiler?
1.1 Goldbird Models Thermostat Control The recommended minimum thermostat setting is 65 °C. Below this ‘cold water corrosion’ is likely to occur which can reduce the life of the heat exchanger and is not covered by the boiler warranty. The boiler thermostat is adjustable from 52°C to 88°C.
