Your local DN3 plumber
Heating that keeps up with homes that have grown
Armthorpe is a large village on the eastern edge of Doncaster, with farmland still running out towards the M18. It is recorded in the Domesday Book, but it was coal that shaped the village you see today: Markham Main Colliery was sunk in 1916 and whole new housing estates were built for its workers, laid out in distinctive rings and crescents that are still clear from the air. After the pit closed in 1996, the old colliery site became a large housing estate of its own.
Two kinds of heating job stand out here. Where an established home has been extended — a kitchen or sun room at the back, a loft conversion, an extra bathroom — the heating has not always kept up: a boiler now working flat out, radiators simply added to the end of the system, an upstairs that never gets properly warm. And on the more exposed edges of the village, the external condensate pipe from a modern condensing boiler can freeze in a hard frost, locking the boiler out on exactly the morning you need it.
We fix the immediate fault and the cause behind it, so the same problem is not back next winter or the next time the family grows. Every gas job is carried out by a Gas Safe registered engineer, and we explain what we have found before we start.

"Needed a new boiler installed asap, got in contact with Ricky. Straight away he quoted & fitted me in quickly. The lads stayed for 10 plus hours and returned the next day to ensure I had water and heating. Can't fault the lads at all."

"Thank you to Rick and the team for fitting our new boiler and radiators. I waited a while before leaving a review, but 6 months down the line it's still working just as good. I would highly recommend."

FAQs
Plumbers in Armthorpe — your questions answered
Can't see your question? Call 07534 793949 — we're happy to help.
My boiler stopped on a freezing morning — is it the condensate pipe?
It is one of the most common causes. Condensing boilers drain water through a plastic condensate pipe, and where it runs outside it can freeze in very cold weather, backing up and locking the boiler out — often with a gurgling sound. Pouring warm, not boiling, water along the outside section usually thaws it, and the boiler can then be reset. For a lasting fix we insulate it, increase the pipe size or reroute it internally.
We have extended the house — do we need a bigger boiler?
Not always, but it is worth checking. An extension, loft conversion or extra bathroom adds to the heat and hot water the boiler has to supply. We work out the heat loss of the house as it is now and compare it with the boiler's output. Sometimes the existing boiler copes once the system is balanced; sometimes it genuinely needs to be larger or a different type.
Can underfloor heating go in our new extension?
Usually, yes — and it suits kitchens, garden rooms and sun rooms well. A wet underfloor system can run from your existing boiler through its own mixing valve and controls, or an electric mat can suit a smaller space. We look at the floor build-up and the boiler before recommending either.
Can you add a radiator without the rest of the heating suffering?
Yes, if it is done properly. The pipe feeding the new radiator needs to be sized correctly, the boiler needs spare capacity, and the whole system needs rebalancing afterwards so water is shared evenly. Tacking a radiator onto the end of a run without that is a common reason upstairs rooms go cold.
Do you cover Edenthorpe, Kirk Sandall and Dunsville too?
We do. We work across the eastern side of Doncaster, including Edenthorpe, Kirk Sandall, Dunsville, Cantley, Intake, Wheatley Hills and Auckley. If you are nearby and not sure, call us and we will confirm straight away.
