Using stove thermometers to ensure optimum efficiency


Using your newly acquired wood/multifuel stove will give months of long , easy  & warm cosy days where you can lounge around just enjoying yourself. However, as with all things that are subject to temperature variations , maintenance checks are essential giving you peace of mind and the satisfaction everything is running under optimum conditions.

Often times these, “checks” may seem as if they might drag you out of your comfort zone but the good news is once you’ve attached it to the stove top or flue pipe arising from it , using a stove thermometer is as simple as making regular readings.  They come in a few varieties and can be wire , hose clipped or magnetically attached.

They are used primarily to avoid over firing , (the resulting extreme temperatures create bad fuel efficiency) and are operated by having an eye gauge in both °Celsius and Fahrenheit. Keeping your stove burning in the Correct range of 115°C – 245°C or  (240°F – 475°F) will ensure the safest operation , whilst simultaneously giving maximum fuel economy.

Running Too Cool

Allowing your stove to reach burning temperatures below 115°C or (240°F) will lead to incomplete combustion creating carbon monoxide, tar, soot and creosote.

Creosote itself , is a condensation residue of coal and/or wood particles , hydrocarbons , gases and other airborne debris. It is formed as gases cool , for example when air in a chimney is not hot enough to push the particles out. Its appearance is of a thick hard black shiny goo which reduces the bore of the flue by sticking to the inner bore.

Running Too Hot

When you allow your stove apparatus to run above burning temperatures of 245°C or (475°F) you risk damage to your flue/liner/cowl and possibly warping your baffle plate.  A significant increase in the risk of chimney fires is created, especially if there has been creosote build up.

Also Please remember a significant part of this maintenance strategy is to get your solid fuel heating appliances swept at least once a year by your chimney sweep.
