A new boiler that suits your home
Replacing your boiler is a significant decision, so it makes sense to choose a system based on what your property actually needs. At D Davies Plumbing & Heating Ltd, we assess your existing heating setup and talk through your heating and hot water requirements before recommending the next step.
Whether your current boiler has become unreliable, repairs are becoming too frequent, or you simply want to replace an ageing system, we can advise you on a suitable new boiler.
Once you’re happy to proceed, we carry out the installation with care, connect the new boiler to your heating system and complete the necessary checks and testing before handover. We’ll also explain the controls so you know how to operate your new boiler properly.
We provide professional boiler installations in Llandeilo, Ammanford, Cross Hands and across Carmarthenshire for homeowners looking for straightforward advice and dependable workmanship.


Replacing an old or unreliable boiler
An older boiler can become increasingly troublesome as components wear and breakdowns become more frequent. If you’re regularly arranging repairs or finding that your heating and hot water are becoming unreliable, it may be time to consider replacement.
We don’t believe in recommending a new boiler when a sensible repair will do. We’ll look at the condition of your existing system and explain your options clearly so you can make an informed decision.
When replacement is the practical choice, we’ll help you select a boiler that suits the property and the demands you place on your heating and hot water.
Contact our team, and we will handle the installation, testing, and final checks, providing you with one local company to work with from the initial discussion to completion.
Professional installation from start to finish
Getting the boiler itself right is only part of a good installation. The way it works with the rest of your heating system matters too.
We take care when connecting the new boiler, checking the associated system and making sure everything is operating correctly before the job is signed off. Safety checks and proper testing form an important part of the installation.
Once the work is complete, we’ll show you how to use the boiler and its controls and answer any questions you have about looking after the system.
And because we also provide boiler servicing and breakdown repairs, you can come back to the same local team when your new boiler needs ongoing care.
