How does a wood burning stove with back boiler work

Can a stove with a back boiler 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.

Does a back boiler have a flue?

Back boilers are “open flued” which means that there must be an open vent to allow fresh air in to replace the fumes that go up the flue. This means that if a fault develops with the ventilation, flue or boiler itself, potentially lethal gasses can be released.

OPEN FIRES WITH BACK BOILERS When lighting, the boiler damper should be closed so that the flue gases pass up the chimney in front of the boiler. When the damper is open, more heat is directed around the boiler, which will make the fire harder to light.

Why would a back boiler 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. … Thus, at the decommissioning stage the system should have been drained and redundant pipework removed along with, ideally, the back boiler itself.

Should boiler be hot to touch?

So to answer the main question – “Should my boiler be hot to the touch?” – the answer is no, but some will indeed get quite warm. Remember that an overly warm boiler is almost certainly an inefficient one, as heat will be leaking out around it rather than into the cylinder, radiators and taps.

Can boilers explode?

Why is my stove leaking water?

Your pipes aren’t insulted enough – One of the most common reasons a stove range hood may be leaking water is lack of proper insulation. On colder days, the hot, steamy air being vented may be hitting parts of your piping that are freezing cold, forming into condensation, and dripping back down.
