Install, maintain and repair
Sterling Heat is a Sittingbourne heating company covering Swale, Sheerness, Canterbury and the surrounding areas. We install, maintain and repair domestic gas, LPG and oil boilers, central heating systems, warm-air systems, hot-water systems and heating controls.
A new gas boiler is the biggest single improvement most homes can make to their running costs. Modern A-rated condensing boilers turn over 90% of the gas into heat, and matched with the right controls they typically cut bills noticeably against a 15-year-old boiler. We size the boiler to the house rather than fitting the biggest one on the van, which is why our installs run quietly for years.
What is included
Every installation is a complete job: removal and disposal of the old boiler, a system flush or power flush where it is needed, a magnetic filter to protect the new boiler, new controls, commissioning with a flue gas analyser, Gas Safe notification and the manufacturer warranty registration. We talk you through the controls before we leave.
Full central heating systems
For an extension, a renovation or a house that has never had central heating, we design and install the whole system: boiler, radiators or underfloor heating, cylinder, pipework and zoned controls. Complete packages with full design and installation.
Our reputation has been built over decades, mostly by word of mouth. If you have any questions, get in touch: we are happy to help.

What size boiler does your house need?
Tell us the rooms and watch the house build itself. We count the radiators the way an engineer would, then size the combi from the standard industry bands, and you get a quote request with the details already filled in.
Lounge, dining room, study and conservatory all count as living rooms. We add a radiator for the kitchen, hall and landing.

What is the old boiler costing you?
Slide to your yearly gas bill and pick the age of the boiler. The maths is simple: an old boiler wastes a share of every pound you spend.

I have used Sterling Heat on few occasions: removing old system and installing new combi boiler, connecting radiators, pipework adjustments, gas hob installation. Always professional and very helpful! Very knowledgeable! Best in the area!
We’ve used Gary several times since buying our house 7yrs ago for small jobs. Now we need a new boiler we feel lucky to have someone we know and trust to do a good job at a fair price.
Gary is great at his job and takes time to make sure it is done to the highest standard. I completely renovated my house so needed heating and wet plumbing.
Questions people ask us
Combi, system or regular boiler: which do I need?
A combi heats water on demand and suits most homes with one bathroom and no room for a cylinder. A system boiler feeds a hot-water cylinder, so two bathrooms can run at once. A regular (heat-only) boiler works with a cylinder and tanks in the loft, and is often the simplest swap in an older house. We tell you which fits at the survey.
How long does a gas boiler installation take?
A like-for-like combi swap is usually one day. Moving the boiler, converting from a regular to a combi, or adding radiators and a full system flush can take two to three days. We give you the timescale with the quote.
Will my new boiler be registered?
Yes. We notify the installation to Gas Safe (which generates your Building Regulations compliance certificate) and register the manufacturer warranty in your name. You get both in writing.
What warranty do I get?
Many of the boilers we fit come with a 5-year manufacturer parts warranty. As a G1 accredited installer we can offer extended manufacturer warranties on selected models. An annual service keeps the warranty valid.
Do you fit LPG boilers?
Yes. We are Gas Safe registered for LPG as well as natural gas, so homes on bottled or bulk-tank LPG in the villages around Swale and Canterbury are covered.
Can you add smart controls?
Yes. Smart thermostats, programmable room stats, zoning and thermostatic radiator valves can all be fitted with the boiler. The right controls often save more than the boiler change itself.
