Domestic servicing for oil boilers
Why service your boiler? Here are the top 5 reasons:
- Regular servicing ensures your boiler is running at its most cost-efficient
- Stay Safe – regular checks reduce possibility of harmful emissions to you and your loved ones.
- Reduced damaging emissions for the environment
- An Annual service will improve the longevity of your boiler.
- Un-serviced boilers are often found to be running at 55-65% efficiently – regularly serviced boilers can run at +95% efficiency
Oil boilers are pretty robust bits of kit, especially when compared to their light weight gas equivalents, which tend to be serviced on a more regular basis by comparison. However, just as your car will still bimble along at 50mph with your tyre pressures at half of what they should be, so your boiler will still heat your house and give you lashings of hot water despite its pressures and combustion levels being drastically wrong. What does this mean? Just like your car, considerably higher fuel bills, excessive, costly & unnecessary replacement of worn out parts and of course a hugely increased chance of ending up on the side of the road in a big plume of smoke on a cold and wet winters night.
Regular servicing ensures your boiler is running at its best. Your boiler running at its best will result in considerably reduced fuel bills, less damaging emissions to the environment, reduced chance of harmful emissions, in the form of Carbon Monoxide, to you, your family and pets and greatly improving the chance of your boiler lasting for many, many more years than an un-serviced one.
But is it worth it??
It’s a difficult one isn’t it? We have attempted to provide a transparent costs list.
Please do read below as to why you should service your boiler regularly.
Question: Why do GasSafe engineers have such soft hands compared to an OFTEC engineer?
Answer: Because OFTEC engineers have to work for a living
Oil boilers need cleaning!! And it’s a big mucky old job
They need totally taking apart, thoroughly cleaned internally and then inspected. Just 1mm of soot on the heating surfaces (typically after a few years even if the boiler is burning cleanly) will increase fuel consumption by 5%, 3mm will be getting close to 10%.
You’ve all heard “your nozzle needs changing”?, Well it does! It’s actually a moving part and it wears out. Yes it will keep spraying oil into the combustion chamber but it will be too much and in a very poor pattern. Your faithful old boiler will still deliver lots of hot water and warm radiators, but at a substantial increase in financial cost and increasingly poorer emissions into the environment.
Un-serviced boilers are often found to be running at very poor efficiency, a well maintained condensing boiler should be up around at least +90%. What does poor efficiency mean….yup.. quite literally, “Money going up in Smoke!”
And finally, poor maintenance is by far and away the highest cause of boiler failure.
Repairing a broken boiler is always going to be a considerably more expensive outlay than regular professional servicing.
