Radiator Replacement in Hedge End

Plumbright Southern offers radiator replacement in Hedge End. We swap rusty, leaking or undersized radiators for new ones, fit new valves and refill the system so every room heats up properly.

When to Replace a Radiator

Replace a radiator if it leaks, shows rust spots, stays cold at the bottom even after a flush, or does not heat the room. It is also worth swapping when you redecorate and want a different style, or when you need more heat in a room after building work.

More Information

Getting the Size Right

Radiator output is measured in BTUs or watts. A room needs enough output for its size, the number of windows and how many outside walls it has. Picking a radiator by looks alone can leave a room cold. We work out the output each room needs before you choose a model.

Like for Like Swaps

If the new radiator has the same pipe centres as the old one, the swap is quick, with no changes to the pipework. Different sizes need the pipes moving, which takes longer. We also fit new thermostatic valves, so you can control the temperature of each room on its own.

Frequently Asked Questions

How long does radiator replacement take in Hedge End?

A single like for like radiator swap usually takes an hour or two, including draining and refilling the system. Replacing every radiator in a house can take a day or more. If pipework needs moving for a different size, allow extra time. We give you a time frame when you book.

Can I replace a radiator without draining the whole system in Hedge End?

Sometimes. On a single like for like swap, the valves on each side can be closed and the radiator removed with only a little water lost. If the valves are old or stiff, or the pipework needs changing, the system usually has to be drained down first.

What size radiator do I need for a room in Hedge End?

It depends on the size of the room, the number of windows and outside walls, and how well it is insulated. A bathroom or a room with large windows needs more output than an inside room of the same size. We measure up and work it out for you before you buy.
