When my old boiler suddenly gave out, Andrew took time to thoroughly investigate, running multiple checks. He offered a range of replacement options and the installation was seamless. His flexible payment terms made the whole process stress-free. A truly knowledgeable gas engineer.

Just got my boiler replaced and relocated by one of the best and most knowledgeable engineers! Fast, affordable and neat installation. Highly recommend Plumb Heating LTD to everyone.

Plumb Heating replaced my leaking boiler, carried out a full power flush on radiators and underfloor heating, and installed a new Vaillant boiler. Very professional, reliable and tidy throughout. Everything explained clearly and completed to a high standard.

A Replacement Done Properly, Start to Finish

Swapping a boiler is more than lifting one off the wall and fitting another. The right size, flue route and controls decide how it performs for the next ten years. Our replacement service includes:

Free home survey – we look at your system before recommending anything
Right boiler for the home – sized for your radiators, hot water use and layout
Old boiler removed – disconnected, taken away and disposed of
Controls and pipework checked – upgraded where they would hold the new boiler back
Commissioned and documented – tested, certified and handed over with your warranty

Signs It Is Time to Replace Your Boiler

Replacing a boiler is a big decision. These are the signs we see most often in Hemel Hempstead homes:

The boiler is over 10 to 15 years old
Repairs are getting more frequent
Spare parts are hard to source for your model
Bills are rising without any change in usage
The boiler struggles to keep up in cold weather
An engineer has advised against further repairs
The boiler has been flagged as unsafe
You want to free space by removing a tank or cylinder
You want to move the boiler to a better spot
You want smart controls your old boiler cannot support

Like for Like, Upgrade or Relocate?

A straight swap is usually the quickest route. If you want to move to a combi, relocate the boiler or change system type, we check what is practical in your home first.

We also advise when a power flush is worth doing to protect the new boiler, and only when the system needs it.

Every Boiler We Fit Is Fully Guaranteed

Every boiler we replace comes with three promises:

12-month parts warranty – all components we fit are covered for a full year
12-month labour guarantee – if any installation issue arises, we will fix it free of charge
Satisfaction promise – if you are not completely happy, we will come back and make it right at no extra cost
