Do you know what colour your gas flame should be?

Do you ever take any notice of what colour your gas flame is burning on your hob? 

On a gas hob, the flame should be blue. This means that it's burning properly with sufficient oxygen to create complete combustion, which in turn creates enough energy to excite and ionize the gas molecules in the flame.

You should always be on the lookout for poorly functioning gas appliances, to keep both yourself and your family safe.  The best way to do this is to keep an eye on the colour of the flame and if you notice a yellowish flame instead of a blue one you should stop using the appliance immediately and call a fully qualified Gas Safe Registered Engineer.

Other signs your appliance may not be functioning safely are yellow or brown soot which has built up around the appliance, pilot lights not working properly or going out unexpectedly, or a consistent strong smell of gas which could indicate a gas leak.

You should always have your gas appliances checked by a qualified Gas Safe Registered engineer on a regular basis to maintain their efficiency and safety. Gas Hobs, Gas Fires, and Boilers are three of the most common gas appliances in a household - all of which should be checked at least annually.

If you think you may have a problem with one or more of your gas appliances or would like to book a routine Gas Safety Check, contact the Harris Heating team today on 0113 250 53 75 or visit our Gas Safety page on our website for more information.
