Radiator installation
Replacing, adding or moving radiators — sized for the room rather than the space on the wall, so it actually heats what it is meant to.
A radiator that is too small will never warm the room no matter how long it runs. One that is too big wastes money and makes balancing the rest of the system harder. Sizing is a calculation based on the room’s dimensions, its windows, what is above and below it and how well it is insulated — not a guess based on the gap under the window.
What we do
Replacing tired radiators, adding one to a cold room, moving them for a redecoration or a new kitchen, swapping to vertical or designer radiators where wall space is tight, and fitting thermostatic valves so each room can be set separately.
Vertical and designer radiators
Popular, and they work — but many designer radiators put out less heat than the plain panel they replace. We will tell you the output figure before you buy, not after you notice the room is colder.
Balancing
Adding or changing a radiator changes the flow through all the others. We rebalance the system afterwards. Skipping that step is why one new radiator can leave the far end of the house cold.
Thermostatic valves
Worth fitting throughout. Rooms you do not use get turned down instead of heated to the same temperature as the lounge.

Frequently asked questions
Why is one radiator cold when the heating is on?
One cold radiator is usually trapped air, a seized thermostatic valve, or a system that has never been balanced. Bleed it first, because that costs nothing and fixes it more often than not. If it stays cold, take the head off the valve and press the pin — a pin that does not spring back is your fault, and freeing it takes minutes.
Why is my radiator cold at the bottom?
Cold at the bottom and hot at the top is sludge, not air. Iron oxide settles in the base of the panel and the water flows over the top of it, so bleeding does nothing. That is a flush rather than a bleed, and it is a whole-system problem showing up in one radiator.
Do I need to bleed all my radiators or just one?
Bleed the cold one first and leave the rest alone unless the problem is across the house. Bleeding everything drops the boiler pressure, so check the gauge afterwards and top it back up with the filling loop if it has fallen. A radiator that needs bleeding every few weeks has air getting in from somewhere, and that is worth finding.
What happens if you never bleed your radiator?
The trapped air sits at the top of the panel, so the radiator gives out less heat and the room never quite gets there. The boiler runs longer to make up for it, which you pay for. Air also brings oxygen to the steel, and that is where the sludge that blocks the rest of the system starts.
Which radiator do I bleed first if my boiler is downstairs?
Start with the downstairs radiator furthest from the boiler, work through the rest of the ground floor, then do upstairs the same way. The idea is to move outward from the boiler and finish at the highest point in the house, since that is where air collects. Check the pressure gauge when you are done.
