Combi Boiler Information – Combi Boiler Reliability

A combi (or combination boiler) is a compact and highly efficient unit giving all the heating and hot water you need, with significant savings on running and installation costs and this is why combis now account for over 50% of domestic boilers fitted in the UK every year.

Unlike a traditional heating and hot water system, a combi boiler system does not store domestic hot water. It heats water directly from the cold mains - as you use it. There's no hot water cylinder, no tank in the loft (and so less risk of freezing and flooding), and none of the connecting pipe work. So you not only save space, but also reduce hot water costs - which can account for up to 60% of a typical domestic fuel bill.

A combi also supplies hot water at mains pressure, giving you exhilarating power showering without the need for a pump. And as, on average, a shower uses considerably less water than a typical bath, the savings on hot water costs and water consumption can be significant.

Why are condensing combination boilers better?

A condensing combi boiler is more efficient due to its ability to extract more heat from the flue gases normally lost to the environment through the flue system.

Energy Saving Tip: Using a fireplace sends valuable heat up the chimney. Reduce the loss by installing glass doors on the fireplace.

IMPORTANT NOTICE

New Government regulations (Part L) require that from the 1st of April 2005 all new boiler installations must be of the 'high efficiency' condensing type. There are very few exceptions to this law.
