How does stove back boiler work?
A wood-fuelled (biomass) stove with a back boiler is a stove that provides heat not only into the room (like a conventional stove) but hot water to run one or more radiators as well. In some instances biomass stoves with back boilers are used to provide domestic hot water as well.
Why do back boilers explode?
When a fire is lit in front of a redundant back boiler, left in a sealed condition, it can heat up and the internal pressure can cause the boiler casing to explode.
Does a back boiler need a pump?
It can also be connected to a series of radiators to provide central heating but usually requires an electrical pump to be fitted to circulate the hot water, some systems can use the gravity circuit to include radiators.
Does a back boiler have a pilot light?
If it has a pilot light, it should be on. A back boiler with a pilot light is probably quite old. If you turn it off it might not relight when you want it on again. Energy from electricity costs about three times as much as energy from gas, so your immersion heater might not be economical.
Why is my back boiler not firing up?
If the boiler is not igniting, there is a possibility the valve is blocked, seized or there is damage in the wired connections. No Pilot Light: When the boiler is not igniting and the pilot light has gone out, this usually means debris has blocked the jet.
Can a back boiler stove be used without water?
Operating a boiler stove without water would certainly invalidate any manufacturer’s warranty but also provide you with limited heat, as the air in an empty tank also acts like insulation limiting the heat output of the stove. This would be most apparent in boiler stoves where the boiler is of the ‘wrap- around’ type.
Can a back boiler burst?
The redundant solid fuel back boiler had been left in a sealed condition and sometime later, when a coal or wood fire was lit in front of the boiler, the unit heated up sufficiently for the internal pressure to cause the boiler casing to explode.
How safe are back boilers?
Old Back boilers are no longer safe, which is why they are illegal. The conventional or old boilers have less efficiency, more energy consumption and expensive maintenance.
How does a back boiler heat water?
Back boilers provide central heating and hot water to a property by using the heat from a gas fire or stove that they are installed behind. To provide hot running water, they must be paired with a hot water cylinder.
What makes a boiler fire up?
Over time, small pockets of air develop and since air is lighter than water, it rises to the top of the radiator, causing it to run inefficiently. This might lead to your boiler not firing….Reason #4: Air trapped in radiators.

Does a boiler have a pilot light?
The pilot light is an important component of all older furnaces and boilers. The pilot light is the flame that lights the gas provided by the main burner. A small amount of gas is constantly released from the gas pipe, meaning that the flame lights the gas and it permanently burns.
Can a back boiler work without a fire?
As long as the flue/chimney is safe an engineer should be able to run one without the other. So if you want to bring the boiler back to life without the gas fire it should be possible.
How messy is removing a back boiler?
The back boiler, its flue, and gas fire – all will be removed unless you want to keep the back boiler fireplace. Removing the gas fireplace and replacing it with an electric fire could cost you more in the short term but less in the long term. So, creating a mess is normal while removing a back boiler.
Can a back boiler overheat?
Boilers will overheat when the hot water that should be sent to the central heating system, taps or a hot water cylinder is being prevented from circulating. This is normally due to a failed part, such as the pump, or a blockage in the system.
Can back boilers explode?
Why are back boilers illegal?
Old Back boilers are not efficient enough, which is why they are illegal to replace. Considering the amount of money you would save on your gas bill if you have a gas back boiler, it would be worth it in the long term.
Can you change the fire on a back boiler?
The main thing you must ensure is that the new fire is compatible with the back boiler as some boilers have been specifically designed to work with a limited range of inset fires. Back boilers are almost obsolete now and there is a limited range of manufacturers making replacement fires for them as a result.
