Types of oil boiler
Oil fired boilers can be just as compact as gas boilers - wall or floor mounted, clean and quiet. The two most popular choices are standard (conventional) or combination (combi) boilers, both available as condensing models.
Standard (Conventional) Oil Boiler
A conventional system incorporates a boiler, feed and expansion cistern, and a hot water cylinder - usually in the airing cupboard. Most suitable for larger households where significant quantities of hot water are needed on demand.
Combination (Combi) Oil Boilers
The high-efficiency condensing combi oil boiler is a space-saving choice that now accounts for well over half of all new domestic boilers installed in Britain each year. No separate storage cylinder required.
Condensing Oil Boilers
Both standard and combi oil boilers are available as condensing models. An extra heat exchanger recycles exhaust gases to pre-heat the system water, reducing energy consumption. The energy savings typically repay the additional cost within 2 to 4 years.
Is your oil boiler wasting you money?
Old G-rated oil boilers can be less than 70% efficient - meaning around 30p of every £1 you spend on heating is wasted. All new oil boilers fitted by Mark Thompson Heating Ltd are A-rated and 90%+ efficient.
