A combi (or combination) boiler is an ingenious space-saving idea, and an incresingly popular choice in UK homes. In fact, combis now account for well over half of all the new domestic boilers installed in Britain every year.
A combi boiler is both a high-effieciency water heater and a central heating boiler, combined (hence the name) within one compact unit. Therefore, no separate hot water cylinder is required, offering space saving within the property.
Further benefits of a combi boiler are significant savings on hot water 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 combi boiler benefit 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.
As with oil-fired appliances, Condensing Oil
Boilers require commissioning at the time of installation.
This simple process ensures that the boiler is working at peak efficiency which, in turn, will result in lower running costs and long term reliability. Annual maintenance is also made easy by a front service access to both the burner and all the internal serviceable parts. This feature enables Condensing Boilers to be fitted neatly and unobtrusively within either the kitchen or utility room environment. Alternatively, if internal siting is a problem, space-saving outdoor versions are available.
Condensing boilers differ from traidtional boilers in that they are designed to capture heat normally lost through the flue system during the combusion process.
Unlike traidtional oil-fired boilers, condensing boilers have a built-in stainless steeel heat exchanger incorporating a unique turbulator baffle system, which cools the gases to a point wher the latent heat, normally lost to the atmosphere through the flue, can be usefully extracted.
The additional energy recovered enables the boiler to operate continously at much higher efficiency levels, resulting in lower heating and hot wter running costs.
It is crucial to look after your boiler by having it serviced annually to keep it running efficiently and cost effectively.
Servicing is carried out by a trained OFTEC technician and repairer.
Boilers are normally required to be serviced annually to adhere to the manufacturer's warranty.
Bunded new oil tanks can reduce the risk of damage to your property and harm to the environment and rivers.
Most tanks are long lasting and can carry a
10-year guarantee. Tanks are installed in line with OFTEC standards by a registered technician providing a lower risk and peace of mind.
Condensing oil boilers operate at extremely high efficiency levels, producing cool flue gas temperatures, resulting a a 'plume' of vapour being visible at the flue terminal.
Risk Assessments and Certificates of Compliance are available to owners of rented properties, renting out to tenants.
Appliances must also be serviced regularly to adhere to insurance company cover regulations.

Many boilers including the Worcester Greenstar condensing boilers are at least 90% efficient, meaning that they turn 90% of the fuel they use into heat.
The official rating for boilers efficiency is the 'SEDBUK' scale (Seasonal Efficiency of a Domestic Boiler) in the UK.
The Worcester Greenstar condensing boilers achieve the 'SEDBUK' Band 'A' rating.
'A' ratings offer the best efficiency and where possible we try to fit this standard for your benefit.
Oil tanks less than 3500 litres should not be positioned within 760mm of a combustible boundary, e.g. a fence/trees. British Standard (BS 5410 - Part 1:1997) must be provided by means of a fire resistant wall which extends at least 300mm above and beyond the ends of the tank.
Under the same guidelines Flu Outlets should be more than 1.8 metres away.
For full details on current Planning and Legislation for consumers refer to OFTEC Home Guides listed at the top of the page on tank replacements, installation and positioning.
Watchman Alarms/Guages are often included in the package of a new oil tank or can be fitted at an additional low cost.
Watchman Alarms indicate:
Oil levels from inside the home or office
Sound to indicate oil loss due to leakage or removal
Sound to indicate refill levels
