Radiator replacement and installation
We replace old cast-iron radiators with new ones, add heating elements and install thermostatic valves. In doing the work we consider the room's heat demand, not just the old radiator's size.

What to consider when choosing
What matters is the radiator's output, the connection type, and the connection spacing. A radiator that's too small won't heat properly, and one that's too big wastes energy. We help choose a suitable model and tell you whether the existing piping allows it.
How to recognise something's wrong with a radiator
- Radiator is hot at the top, cold at the bottom — sludge layer inside
- Radiator doesn't heat up at all even though the thermostat is open
- Water drips from under the radiator — leak in a connection or the body
- Radiator makes a gurgling sound — air in the system
Who it suits
- Apartment owners upgrading old cast-iron radiators
- House owners building or expanding their heating
- Housing associations planning radiator replacement in several apartments
Single radiator replacement or changing the connection layout?
Replacing a single radiator means the existing connection points and piping stay the same — the old heating element comes off and a new one with the same connection spacing goes on in its place. This is quick and limited to one room.
Changing the connection layout is a bigger job: the radiator moves to a different spot, the connection is rerouted from inside the floor or wall, or a single-pipe solution is replaced with a more flexible one. Then you need to account for the pipe route, opening up finishes, and, in an apartment building, agreeing on closing the riser.
What affects the scope of the work
- Number of radiators and access (niche, windowsill, enclosed cover)
- Whether the connection spacing and pipe type suit the new heating element
- Whether the system is within one apartment or a whole building riser
- Whether thermostatic valves are installed and balancing done at the same time
Frequently asked questions
- Does the whole building's heating need to be shut off to replace a radiator?
- In an apartment building, closing the riser is usually enough, which we agree with the management company. In a house we only shut off the necessary branch.
- The radiator doesn't heat evenly — do I need a new radiator?
- Often not. If the problem is a sludge layer, a heating system flush helps, not a radiator replacement.
- Can a radiator be added to a room that doesn't have one now?
- Often yes, but it requires bringing a connection from the existing piping and balancing the system afterwards. We check on site whether the existing layout allows it.
