Replacement panels, vertical and column radiators, towel rails and full-house upgrades across Wigan and Bolton. We work out the output each room needs, fit it neatly, and balance the whole system before we leave.
Radiator size calculator
Enter the room size and a few details. You’ll get a rough heat output in watts and BTU, the figure every radiator is sold by.
A rough guide only. Real output depends on your boiler’s flow temperature and the room itself, so we always confirm it on the survey before ordering.
Choosing a style
Seen from above, a radiator is panels and fins. More of both means more heat from the same wall space.
One panel, one row of fins. Good for small rooms, hallways and tight spaces behind doors.
Two panels with fins between. More heat than a single without much extra depth.
Two panels, two rows of fins. The workhorse for living rooms and bedrooms.
Traditional or tall designer radiators. Great where wall width is short but height isn’t.
Heated ladder rails for bathrooms and kitchens, in chrome, white or anthracite.
Fix or replace?
Not every cold radiator needs replacing. Here’s what we usually find, and what you can safely try first.
| What you notice | Usual cause | The fix |
|---|---|---|
| Cold at the top, warm at the bottom | Air trapped in the radiator | Bleed it with a radiator key and top up the boiler pressure You can try this |
| Cold at the bottom or in the middle | Sludge (black iron oxide) settled inside | Radiator flush, or a full system power flush if several are affected |
| One radiator stone cold | Stuck valve pin on the TRV, or the valve shut | Free or replace the TRV, then rebalance |
| Downstairs hot, upstairs lukewarm | System out of balance, or a tired pump | Balance every radiator; check the pump and circulation |
| Drips or green crust at a valve | Worn valve gland or fitting | Repack or replace the valve |
| Rust spots or pinhole leaks on the panel | Corrosion from the inside out | Replace the radiator; corrosion means the system needs inhibitor too |
How the job goes
We measure the room, work out the output it needs and give you a fixed price, so there are no surprises.
System drained, or pipes frozen on single swaps to save time. New valves fitted, pipework kept neat, floors protected.
Refilled with inhibitor, every radiator balanced so the whole house heats evenly, and leak-checked before we go.
Neat pipework matters
Doing a bigger heating upgrade? We can price a new boiler online in 60 seconds and fit it with the radiators, and add smart heating controls so each room runs at its own temperature.
It depends on the room size, how many outside walls and windows it has, and how well the house is insulated. Use the calculator on this page for a rough figure in watts and BTU. We confirm the exact output on our survey so the radiator actually heats the room.
A like-for-like swap is the cheapest job because the pipework is already there. New radiators that need pipework run to them cost more. We give a fixed price after a quick survey, and can often price simple swaps over the phone on 01942 466 486.
A like-for-like swap usually takes 1 to 2 hours. A new radiator with pipework alterations is around half a day. A full house of radiators as part of a heating upgrade is normally 1 to 2 days.
Cold at the bottom or in the middle usually means sludge (black iron oxide) has settled inside. A radiator flush or a full system power flush clears it. Cold at the top is different: that is trapped air, and bleeding the radiator usually fixes it.
Yes. We reroute the pipework, often under the floor, so you can put a radiator where it suits your new layout, and make good the old pipe runs.
Either. We can supply good-quality radiators at trade prices and guarantee the whole job, or fit radiators you have bought yourself.
Modern radiators with thermostatic valves let you heat only the rooms you use, and a clean system heats up faster. Combined with a flush and balancing, most customers notice the difference.
Like-for-like swaps can often be priced over the phone. Gas Safe Reg. 939000, 132 five-star reviews, covering Wigan, Bolton and Leigh.
