Open Flue

The open flue type of boiler is now really only found in houses that were built many years ago. They are very heavy and would not be able to secure to a wall, as the more modern versions do. They take quite a lot of its air for combustion from their surrounding atmosphere which normally means the room where it is situated. The fumes from the flue exhaust into the room and are not very safe or health friendly. A Richmond Plumber is experienced in open-flued boilers and can advise on ventilation options. Exhaust type fans were fitted at the flue to try and force the gases out of the house, with many detection devices on the burner so that the boiler shut itself down at the first indication of these gases being present, however the boiler still had to be monitored even though these safety features had been added. Boilers have undergone great design and safety innovations in the last ten years. They now boast a first class safety and reliability record.


Vent:

Usually, additional ventilation is required because the combustion air is taken from and vented back into the same room space. Richmond Plumbers can fit extra ventilation if required for this type of boiler. Just to keep a door open really does not suffice as then, the house gets cold and there is more need for the boiler heat. So people would play Russian roulette with their lives. The vents would be covered but they may also have been covered by things like sofas and chairs, so the vent could not escape to atmosphere. The worse the ventilation , the worse the burning action of the boiler, leading to carbon monoxide production, that is completely free of smell and taste and is deadly if inhaled.
