Boiler Temperature Rising and Falling Rapidly | DIYnot Forums

Sep 03, 2019 · The boiler is basically repeating the same routine: 1) The flame lights, and the temperature display rises rapidly (around 1 degree per second) until it hits around 60 degrees or more. 2) The flame then goes out, and the display drops to below 50 before the flame lights again and repeats the cycle. The hot water is still fine, but I'm just

BOILER CONTROLER SETTINGS EXPLAINED - AEL Heating

May 13, 2014 · Some programmable thermostats have a set back temperature which is like a default or standby temperature - when the heating isn't "on", for example overnight, it will still maintain the house at this temperature. What is a boiler interlock? This is the system which allows your thermostat and programmer to tell the boiler when to turn on and off.

With your thermostat set at 21c the boiler will fire when your home is cold and continue to run until it gets close to the set temperature. But it will stop within 1-1.5 degrees it will then calculate how much more it needs to fire and for how long until it gradually brings the temperature up to the set temperature.

Boiler keeps coming on then stops | Screwfix Community Forum

Jan 21, 2015 · I noticed that when I put the temperature down on the thermostat, the heating stops and doesn't come on- so this is working fine no problems. However, when I put the temperature right up, the boiler does start running but it runs for about 30 seconds then stops for 20 seconds then runs again. It does this continuously. The radiators get hot OK.

It can vary from 70 degrees (room temperature) up to 180F if you need it. The boiler is maintained at a different scale, the 180 to 140 range because you have to. Oh well. But the radiator will "sip" this water and return and equal amount back to the boiler. The boiler water not sent out keeps the boiler warm.

Boiler – Fundamentals and Best Practices

When heat is added to water, its temperature rises at a rate of 0.56°C (1°F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0°C (32°F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100°C (180°F) This rise in temperature can be detected and is called Sensible Heat
