50 YEARS SERVING SUNDERLAND
Boiler Installation,
In Sunderland
As a boiler replacement specialist and local boiler installer covering Sunderland, we carry out gas, LPG and electric boiler installation across Tyne & Wear every year.
A large share of our Sunderland work is combi boiler installation – specifically combi-to-combi replacement, swapping an ageing combi for a modern, efficient one, in both apartments and traditional terraces, many originally fitted in the 1990s and early 2000s.
Terraced properties often have specific space and flue-position quirks that need an engineer who knows the local housing stock.
BOILER UPGRADES
Boilers We Install And Upgrades Availables
We primarily install Worcester Bosch, as long-standing Accredited Installers (up to 12-year warranty), and are also Accredited Installers for Baxi and Viessmann. Alongside combi and electric – our two most common installs in Sunderland – we also fit system, traditional (regular) and LPG boilers, plus unvented cylinder systems, where a property calls for it.

BOILER TYPES
Which Boiler Is Right for Your Home?
The right boiler depends on your property, not just your budget. As a rough guide:
Combi Boiler
Traditional Sunderland terrace with an existing combi – usually a straightforward combi-to-combi replacement
Electric Boiler
Flat or smaller property, especially with no flue – often ideal for an electric boiler
System Boiler
Larger home or higher hot water demand – a system boiler or unvented cylinder may suit better than a combi
Unsure?
Older or unusual setup, or not sure what you’ve currently got – free home survey and an honest recommendation, not a one-size-fits-all answer
QUIET, LOW MAINTENANCE, FEWER PARTS
Electric Boilers
In Sunderland
Electric boilers are a particular specialism for us in Sunderland and are often an excellent choice where a gas connection or flue isn’t practical. They can be ideal for apartments, conversions and smaller properties, especially in some of the city’s older buildings where flue routing can be difficult.
We primarily install the EHC Slim Jim range from The Electric Heating Company. Their compact design makes them a practical solution where space is limited or mains gas isn’t available.
Running costs work differently to gas, as electricity costs more per unit, so they generally make the most financial sense in smaller, well-insulated homes. Not sure if an electric boiler is right for your property? We’ll talk it through honestly during a free quote.
DO YOU NEED A NEW BOILER?
Benefits Of A New Boiler
A new boiler isn’t just about fixing something broken – it comes with real, practical benefits. A new A-rated condensing boiler cuts both bills and emissions compared with an older, inefficient one – often a noticeable difference in Sunderland’s traditional terraces.
We’ll give you a straight comparison of running costs for your specific property during a free quote, rather than a generic estimate.
- Lower running costs, especially compared with an older, inefficient boiler
- Far fewer breakdowns and call-outs than an ageing system
- A full manufacturer's warranty for peace of mind
- Compatible with smart heating controls, for better day-to-day efficiency
- Lower carbon emissions than an old, inefficient boiler
AFFORDABLE SERVICING
Boiler Servicing
In Sunderland
Regular servicing keeps your boiler safe, efficient, and within its warranty terms. Our Gas Safe engineers carry out a full service every visit – visual inspection, flue and ventilation checks, system pressure, condensate trap and filter, and more. We service all makes and models of domestic boiler.
Why annual servicing matters:
- Keeps your boiler running efficiently, which helps keep bills down
- Checks safety components, reducing the risk of leaks or faults
- Catches small issues before they become expensive breakdowns
- Keeps your manufacturer's warranty valid - most require an annual service
CP12 GAS SAFETY
Landlord Gas Safety Certificates In Sunderland
If you’re a landlord, we also provide CP12 Gas Safety Certificates across Sunderland. During the inspection, we’ll check all gas appliances, pipework and flues, ensuring your property meets current gas safety regulations and providing the documentation you need to stay compliant.
FREE EXTENDED WARRANTIES UP TO 12 YEARS
Boiler Repairs
In Sunderland
Many of Sunderland’s traditional terraced homes still rely on older boilers, so we attend a steady stream of boiler repair call-outs. The most common faults we see include no heating or hot water, low boiler pressure, faulty diverter valves and radiators that aren’t heating up properly.
We repair all major domestic boiler brands. Our engineers carry a wide range of commonly needed parts and will always look to repair your boiler before recommending a replacement where it’s practical and cost-effective to do so.
HONEST RECOMMENDATIONS
Repair or Replace?
Not every fault means you need a new boiler. As a rough guide, a single fault on a boiler under 8-10 years old is usually worth repairing; frequent breakdowns, an ageing boiler, or a repair bill that starts approaching the cost of a service visit is often the point where replacing makes more sense. We’ll give you a straight recommendation during the call-out or survey – not a sales pitch either way.

“Will and his team were helpful and pleasant to deal with throughout the replacement of aging boiler. There was a lot to get through in a single day, but they arrived promptly with a strong team and got through the work quickly and efficiently, leaving everything tidy and clean behind them”
“Alex and Kyle fitted a new boiler moving it to the loft. Lovely guys, polite and friendly. The quality of work is exceptional. Despite it being in the loft where it will not be seen the pipes are really neat. Have a look at the photos. Never use anybody else.
“Just had a boiler installed by Housewarmers to replace the one they installed 18 years ago, and serviced annually by them.
Great service from a super friendly team. Fast and efficient installation, all rubbish removed and house left clean and tidy.
We have recommended Housewarmers to a few of our friends and they haven’t been disappointed with the level of service."
“I have had Housewarmers servicing my boiler for the last 19 years. We were looking at getting a new bathroom makeover and decided to ask Will at Housewarmers to give me a quote. We had the new bathroom installed in 2 days, this was for new wall panels, radiator, thermostatic shower, shower cubicle, and flooring.
Excellent job by Alex and Kyle.”
