Radiator and Heating Repairs in Ashbourne
Radiators cold at the bottom, a heating pump that's gone, valves that leak. One local plumber who covers Ashbourne rings you with a price.
Free, no obligation. One local plumber prices it, not five.
What does it cost in Ashbourne?
Replacing or adding a radiator costs €150–€600. A new central heating pump is €320–€460. A power flush is €1,299. Bleeding radiators costs nothing: do that first.
What to do first
- Bleed the radiators with a radiator key while the heating is off, starting downstairs.
- If you have a sealed system, check the boiler pressure after: about 1 to 1.5 bar cold.
- Cold at the bottom and warm at the top means sludge. Cold at the top means air.
- Note which radiators are cold. The pattern tells the plumber where to look.
What happens on the day
- The plumber checks the pump, the valves and the pressure, and balances the radiators so they all heat.
- A radiator is swapped on the same valves where it can be, which is the quick and cheap way.
- A power flush pumps cleaning fluid through the system to clear the sludge, then fits a magnetic filter to keep it clean.
- Every joint they touch is checked for leaks with the heating up to temperature.
What can go wrong, and how a good plumber avoids it
Paying for a flush the system didn't need
A good plumber checks the water first. Clear water and cold radiators is balancing, not sludge.
Weeping valves after the job
New valves where the old ones are seized, not forced.
A radiator that's too small for the room
Sized for the room, not just for the gap on the wall.

Radiators and heating: questions
Why are my radiators cold at the bottom?
Sludge: rust and dirt settled in the radiator. Flushing it, or a power flush of the whole system, clears it.
How much does a power flush cost?
€1,299 for most houses, more for a big system. A magnetic filter after it keeps the system clean.
Can I fit a bigger radiator on the same pipes?
Often, yes. A plumber checks the pipe size and the boiler can feed it.
Why does my heating make banging noises?
Air in the system, a pump running too fast, or scale in the boiler. A plumber can tell which from where the noise is.
