Gas boiler servicing in Sandhurst

Owlsmoor and College Town

Correct blue flame picture in a Solo 2PF

Clean blue flame picture from a Baxi Solo 2PF. Red, orange and mauve colour tinges in the flame are normal. Pale yellow flames, candle flame yellow, would indicate incomplete combustion and a risk from carbon monoxide.

Whether we’re servicing gas boilers or fires our first consideration is your safety. With a boiler we check the location of the appliance, that there is sufficient air for combustion and cooling as per the manufacturer’s instructions and we check the condition and operation of the flue to ensure that it is undamaged and is removing the products of combustion safely.

Unless the manufacturers specify otherwise we partially strip the boiler and check and clean the burner and injectors, the flue-ways through the heat exchanger, the pilot burner and the combustion chamber. As we re-assemble the appliance we check the integrity of the combustion casing and the condition of the casing seals to try to eliminate any risk of poisonous flue gases entering the room.

Finally, where it’s possible we run a combustion analysis test. This is particularly important with high efficiency boilers (also known as condensing boilers) but provides us with useful safety information for older appliances too. The ratio of carbon monoxide to carbon dioxide in the flue gases is a good indicator of the safety of the combustion.

Electronic combustion gas analysers also allow us to check the efficiency of room-sealed appliances, calculating how much heat is usefully passed through the house and how much is wasted with the flue gases.

We run another web site recording information about central heating problems and fault-finding of gas boilers and heating controls. You can find it at The site isn’t finished but we’ve posted a number of useful articles there, including articles on radiator balancing, boiler efficiency, central heating system pressure and condensate problems. As we find time we’ll improve the look of the site and add more articles.

Pilto flame in a Baxi Bermuda

The pilot flame on older appliances is used to cross light the main burner. It also heats the thermocouple tip (visible as the black rod in the picture), generating electrical energy which operates a magnet holding the main gas valve open. It the pilot blows out the thermocouple cools and the main gas valve closes.

Testing with an Anton Sprint (Telegan) gas analyser

Combustion analysis on an old Baxi Bermuda 552. The fire front has been removed. We’re measuring main burner pressure and checking the ratio of carbon monoxide to carbon dioxide at the top of the main heat exchanger in the primary flue. On open-flued appliances the combustion ratio can also be checked in the secondary flue. Except for testing, the back boiler unit is not normally run with the fire front removed as its is a combination unit.
