You could be considering a radiator repair or a radiator replacement if a current installation is noisy, has leaks or isn’t heating up a property efficiently. Dr H2O can diagnose all common issues quickly, like faulty valves, leaking pipework or a problem with a thermostat.

Faulty valves account for much of our repair work. These can easily be repaired, or replaced, at a competitive price. Our objective is to restore a home’s heating supply with the minimal of disruption.

If an economical repair isn’t possible, we consider a replacement.

Radiator Repairs


As already mentioned, most radiator faults trace back to the valves. These control hot water flow but, when they fail, it can impact the heating supply and result in cold, leaking or noisy radiators. Our engineers carry popular spare parts for boilers and central heating systems, and usually restore heating supplies on their first visit.

Radiators that warm unevenly or have cold spots are likely affected by air or sludge. These issues can be resolved with powerflushing.

A clean system will keep your property warmer and cost you less.

Radiator Replacement


If an existing installation in Carshalton, Sutton, Wallington or the surrounding areas can’t be repaired, a radiator replacement service covers the supply and installation of new, energy-efficient products which improve comfort and warmth in the home. We can upgrade single radiators in one room or across the whole of a residential property.

Under current regulations, new radiators in any room without a main thermostat must have thermostatic radiator valves fitted.

These can be individually adjusted to:

  • Give individual rooms added comfort
  • Make heating more controllable
  • Reduce your outgoing energy costings

Customers also have the option to remove radiators completely and to have one of our dry or wet underfloor heating systems fitted.

Keeping the home warm is especially important during the cold autumn and winter months when temperatures drop significantly, and it helps to have a responsive radiator repair or radiator replacement service available. Because we can completely upgrade central heating systems by also installing new boilers from a range of manufacturers, the restoration of your heating and hot water supply won’t be a problem.
