Southwest Oil Heating Specialists
Cornwall's premier "OIL-ONLY" service & installation, oil heating services company.

We pride ourselves on our personal & prompt service, to ALL of our clients.

We have a highly trained & professional group of dedicated, local heating engineers ready to maintain & install all of your hot water & heating requirements, throughout your property.
Services
SOS heating Ltd specialise in oil boiler services, repairs & general maintenance for the Cornwall area and cover all types of oil-fired heating and cooking systems. We are a family run Cornish business, based in Hayle & Truro and established in 2003. Many places in Cornwall do not have access to natural gas.
New figures released today from the Oil Firing Technical Association (OFTEC) show that oil is currently the cheapest way to heat your home in the UK. The figures also show that an oil user can save 192 a year just by converting their boiler to a condensing boiler, which is more efficient and releases much less CO2 than a non-condensing boiler.
A fire valve is an important safety feature of an oil installation. BS 5410 Part 1 : 1997 (which is the accepted industry means of compliance with the Building Regulations) requires that a remote acting fire valve should be installed so as to cut off the supply of oil before it enters the building remotely from the appliance in the event of an overheat/fire situation.
Oil Based heating and cooking systems run on domestic kerosene. Oil-fired boilers require an annual service. In fact anything that uses a " pressure jet " burner only requires a once a year service, such as a Rayburn 400 series cooker. However all " vaporising" cookers (cookers that use a wick & stay on permanently) require a 6 month general service to stop them from going out (which is inevitable) & to keep them running at their most efficient.
Due to the vast range of stock we carry on our vans, at all times, we are able to repair 99% of all boiler, cooker and stoves on the same day that we visit you. We look to get to our regular customers the same day or the next day at the latest, so being without heating and hot water is something our customers never experience.

Positive: Professionalism
We had a boiler put in our house, and the work was done to the highest standard and the team were so friendly and professional. We've just had the boiler serviced and are extremely happy and would highly recommend Ryan and SOS Heating.

We had SOS heating to replace my oil boiler and install a much larger boiler and hot water tank in the loft. The team of Carl and Josh were outstanding, working the minute they set foot in the house. I have never had workmen in who were so tidy, efficient and cleaned up after themselves! Exceptional service!

Excellent company.
I have used SOS for a wide range of annual services on oil central heating boilers at three different properties, to service a modern oil fired Rayburn, to repair a faulty boiler and most recently to install a Hive smart thermostat.
Reliable, professional, fair prices and likeable staff.
