Installing Oil Boilers in Wiltshire since 2008
Centra Heat Swindon has been proud of WAI ( Worcester Accredited Installers ) since 2008. During that time, we have installed and serviced hundreds of Worcester boilers in Sheffield and South Yorkshire. If you have a Worcester Greenstar Greenstar Heatslave II, Danesmoor System, or Danesmoor Regular models that are still in their Guarantee period and require annual service, we would always advise that you use a WAI company.
Whether you’re considering a new installation, need advice on servicing, or want to understand how oil boilers work, we’ve got you covered.
It burns oil from a storage tank to create heat and then transfers it to central heating water, which flows through your radiators.
If you have a regular or system boiler, the heat would be sent to warm the water in a storage tank or cylinder, ready to use when needed. If you have an oil combi boiler, both heating and hot water are produced instantly on demand.
An oil boiler should be serviced annually to keep it running efficiently and safely. Regular servicing helps prevent breakdowns, improves efficiency, and ensures compliance with manufacturer warranties.
Modern condensing oil boilers are highly efficient, with some models achieving over 90% efficiency. This means more heat is used to warm your home rather than being lost as waste.
The right boiler size depends on your home's size, insulation, and heating demands. A heating engineer can assess your needs and recommend the best option for efficiency and comfort.
Oil consumption varies depending on boiler efficiency, home size, and usage, but on average, a household may use 1,000–2,000 litres of oil per year. Regular servicing can help reduce fuel consumption.
An OFTEC-registered engineer is a qualified professional who installs and services oil boilers to industry-approved safety and efficiency standards. Using an OFTEC engineer ensures compliance with regulations and high-quality workmanship.
A well-maintained oil boiler typically lasts 15+ years, but regular servicing is key to extending its lifespan and keeping it running efficiently.
Yes! Upgrading to a modern condensing oil boiler can cut fuel costs and improve heating efficiency, making it a smartlong-term investment.
Oil boilers are still available, but the UK government is encouraging greener alternatives like heat pumps. However, modern, efficient oil boilers remain a good option for homes without access to mains gas.
No, but if you're installing a new oil tank, it must comply with building regulations. An OFTEC-registered engineer can ensure everything is installed correctly.
