Radiators & heating
Warm rooms, quiet pipes
New and replacement radiators, designer towel rails and moving radiators, fitted neatly and balanced so every room heats up.
Radiator work
The right radiator, in the right place
Old radiators that take an age to warm up, a towel rail that barely gets warm, or a radiator stuck behind the sofa: Loui can replace, upgrade or move them, with neat pipework that's clipped and finished properly.
He'll help you pick a radiator with the right heat output for the room, so it's warm and not just good-looking. New radiators are fitted with thermostatic valves, filled, bled and checked for leaks before he leaves.

Choosing a radiator
Radiator types Loui fits
The right choice depends on the room, the wall space and the look you want. Loui will check the heat output each room needs.
Panel radiators
The everyday choice. Single, double or triple panels give lots of heat for their size and suit most rooms.
Column radiators
A traditional look that suits period homes and modern rooms alike, in white, anthracite and other colours.
Vertical radiators
Tall and slim, ideal where wall space under windows is limited, such as hallways and narrow kitchens.
Heated towel rails
Chrome, black or designer rails sized to warm your bathroom as well as your towels.
Thermostatic valves
TRVs let you set each room to the temperature you want, so you're not heating rooms you don't use.
Radiators moved
A radiator in the way of your plans can usually be moved, with new pipework run neatly to the new spot.

Signs your radiators need attention
Is your heating telling you something?
These are the most common signs that radiators or pipework need a look. Most are quick to sort.
- Cold at the top
- Cold at the bottom
- One radiator stays cold
- Some rooms never warm up
- Banging or gurgling pipes
- Drips from a valve
- Needs bleeding every few weeks
- Very slow to heat up
Getting the size right
Why heat output matters
Every radiator has a heat output, usually shown in watts or BTUs. A radiator that's too small for the room will run flat out and still leave you cold. One that's far too big can make a small room stuffy.
The right output depends on the size of the room, how many outside walls and windows it has, and how well it's insulated. Loui works this out for each room before recommending a radiator, so it looks right and keeps the room comfortable.

Heating questions
Radiators, answered
How do I know what size radiator I need?
It depends on the room's size, windows and walls. Loui works out the heat output the room needs before recommending a radiator.
Can a radiator be moved to another wall?
Usually, yes. New pipework is run to the new position and the old pipes are capped off neatly.
Why is the top of my radiator cold?
That's often trapped air, and bleeding the radiator may sort it. If a radiator is cold at the bottom or some rooms never warm up, the system may need cleaning or balancing.
Can you take a radiator off so I can decorate?
Yes. The radiator is removed, the valves are capped, and it's refitted, filled and bled when you're done.
Can I swap my radiators for a different style?
Yes. Loui can match the pipe positions where possible, or adjust the pipework neatly if the new radiator is a different size.
