Types of oil boilers

Oil fired boilers are either wall or floor mounted, clean and quiet. The two most popular choices of oil fired boiler are standard (conventional) or combination (combi) boilers and all modern oil boilers are condensing (high efficiency).

Standard (conventional)

If you are replacing an older model of boiler, the chances are that you will have a standard (conventional) boiler. A typical conventional system incorporates a boiler and extended controls, a feed and expansion cistern, and a hot water cylinder (usually in the airing cupboard), which is often fed by a cold water storage cistern located in the loft.

This type of system is most suitable for larger households where hot water is needed on demand and in significant quantities for heating, baths, washing machines, dish washers and so on.

Combination (Combi)

The high efficiency condensing combi or combination oil boiler is an ingenious space-saving idea, and an increasingly popular choice in British homes. In fact, combination boilers now account for well over half of all the new domestic boilers installed in Britain every year.
The major difference between a combi and any other type of boiler is that a combi eliminates the need to store hot water - so there is no hot water cylinder in the airing cupboard. It is both a high-efficiency water heater and central heating boiler, combined (hence the name) within one compact unit which usually sits in the kitchen or utility room, or sometimes in the airing cupboard. The space savings result from the fact there is no hot water storage cylinder, cold water storage cistern in the loft or other familiar components of a standard (conventional) heating system.

The further benefits of this are a significant saving on fuel costs, and the fact that hot water is delivered through your taps or shower at mains pressure. So you can enjoy powerful showering without the need for a pump. Another benefit of combination boilers is that it can generally save you money on installation time and costs, since no tank in the roof space means less pipe work and a shorter installation time.

Combi boiler systems are generally more suitable for smaller households, flats and bungalows where space is at a premium and there are a smaller number of users with modest heating and hot water demands, although some of the latest combination boilers can suit larger households.

Condensing Boilers

Both standard and combi boilers are condensing boilers. Condensing oil boilers are designed to recycle the heat with an extra heat exchanger so that the hot exhaust gases are used to pre-heat the water in the boiler system, therefore reducing energy consumption and costs. Condensing boilers cost a little more but the energy savings will repay that extra initial investment in 2 to 4 years of normal use.
