About This Service
A new boiler designed around your home

All work is completed by Gas Safe registered engineers to current safety and building-regulations standards, including removal of the old unit, full commissioning and handover. We design each system to suit house size, hot-water demand and boiler location, then test and certify the installation.
We're heating engineers based in Great Dunmow, serving Stansted Mountfitchet, Bishop's Stortford, Braintree and the surrounding area, and our boiler installation in Great Dunmow covers everything from a like-for-like swap to a full system change. You can see every town we cover on our areas page.
Our Process
How It Works
Survey & System Design
On-site survey to confirm property heat demand, flue route and pipework. We advise on combi, system or heat-only boilers and recommend controls and magnetic filters.
Safe Removal & Install
Engineers remove the old boiler, install the new unit, fit flue and controls, and complete necessary pipework and component upgrades to current regs.
Testing, Handover & Paperwork
Full commissioning, safety checks and system balancing. You receive Gas Safe ID, compliance paperwork and clear user instruction for the new boiler and controls.

Should you replace your boiler?
It's usually worth thinking about a replacement when:
the boiler is 12 to 15 years old or more, especially if it's an older non-condensing model
it needs repairs most winters, or the same fault keeps coming back
parts for it are getting hard to find
your gas bills have crept up while your use hasn't changed
A modern condensing boiler uses noticeably less gas than an old non-condensing one. But a new boiler isn't always the answer, and we'll tell you honestly when a repair makes more sense. Our post on boiler repair or replacement goes into more detail.
What affects the cost of a new boiler?
We price every installation after the survey. The main things that shape the cost are:
The boiler: its type (combi, system or heat-only), output and make.
Changing type: a like-for-like swap is simplest. A change from a tank system to a combi, or the reverse, means more pipework.
The flue: a new or longer flue run, or one through the roof, adds work.
Pipework and radiators: older systems may need pipework upgrades.
System cleaning: a powerflush where there's heavy sludge, to protect the new boiler.
Controls: a standard thermostat, or smart controls.
What every installation includes
A site survey and clear quote
Removal of the old boiler
Your new combi, system or heat-only boiler
Flue, condensate and controls fitted
A magnetic filter to protect the boiler
Pipework upgrades agreed at the survey

Gas Safe compliance paperwork and a handover of the controls
What our customers say
"5***** Couldn't give anything less for the amazing service we received from Chris. From the first quote right through the planning to having a new boiler fitted along with a new radiator and some new radiator valve's fitted by his able colleague David. They certainly both went the extra mile, quite literally, when the Hive wall control wasn't working and Chris had to track down a new one." - Terri, Google
"I was told I needed a new boiler by the company who serviced the appliance from new for the past 6 years. Decided to get a second opinion and chose He@Heating on the strength of the excellent reports it has. On inspection a new boiler was not required just a faulty component, which was fitted promptly at a very competitive price." - George, Google
FAQ
Frequently Asked Questions
Choice depends on hot-water needs and existing cylinder space. Combi boilers suit smaller homes with no cylinder; system boilers work well with a separate hot-water cylinder and multiple bathrooms; heat-only boilers are used in older systems. We survey your property and recommend the most efficient option.
Most like-for-like combi replacements are completed in a day, including commissioning and handover. Larger system installs, new flue runs or work requiring significant pipework will take longer and are scheduled after a site survey.
Yes. Installations include correct flue positioning, condensate discharge and integration of smart controls where requested. We also fit magnetic filters and other recommended components to protect the system and improve longevity.
You will get the relevant compliance paperwork and commissioning records upon completion. Our engineers are Gas Safe registered and will provide evidence of work carried out and guidance on user operation and maintenance.
Often we can reuse existing radiators and pipework, but older systems may need upgrades or a powerflush to remove sludge. We assess system condition during the survey and quote any necessary remedial work before installation.
New boilers come with a manufacturer's warranty, and the length depends on the make and model. Most manufacturers need the boiler registered and serviced every year to keep the warranty valid. We'll explain the cover for the boiler you choose, and our boiler servicing keeps it in place.
