Yes. Our radiators work with all central heating systems. All our connections are BSP and work with either manual or thermostatic valves.
It is not a problem with replacing individual radiators into your existing system. When new or additional radiators are being installed, the system should be drained, cleaned and flushed in accordance with BS7593 and a good quality inhibitor, suitable for mixed metal systems, should be used to protect the system.
You can use our simple Heat Calculator in this website to work out how much heat your radiator needs to give out. We list the heat output of each radiator, so it's easy to see which are suitable for you.
In a larger space you might need to have two or more radiators. Just make sure that their combined output adds up to the total you need. Before placing your order, you should confirm your requirements with your plumber or heating engineer.
We have chosen the radiator sizes most likely to match your requirements. If you would like a radiator manufactured to a different height or length, please let the Walney Team know.
Yes, you can use any type of central heating boiler with our radiators.
You can go ahead and have the pipework installed. The radiator can be connected later. Call the Walney Team to discuss the Pipework connections and tolerances.
No. However, if you have a central heating expansion tank, the top of the radiator must be at least 1 metre (or 40 inches) below it. If you have a combination boiler, there is no problem.
Cast iron radiators are highly efficient heat emitters and hold their heat much longer than standard steel panel radiators.
Tests show that the best place is in the coldest part of the room, usually near a window. Placing a radiator under the window will counteract the cold downdraughts and prevent condensation.
However, with double glazed windows and modern levels of insulation, it is usually possible to locate your radiators away from windows in the position you decide is most pleasing aesthetically.
Some designer radiators have flow diverters inside the water-carrying tubes to divert the water flow around the whole radiator.
To convert watts to Btu's, multiply by 3.413.

60Δt allows for older boiler systems, whilst 50Δt is the new European testing standard for modern boilers, such as condensing boilers, with lower flow temperatures of 75° flow, 65° return. For an approximate conversion from 50Δt to 60Δt, multiply the 50Δt by 1.264.
What is the difference between Thermostatic Radiator Valves (TRV) and manual valves?
Thermostatic radiator valves control the temperature of the radiator via a built-in sensor, which automatically opens and closes the flow of water into the radiator, maintaining the room at the pre-set temperature. A manual valve can only control the temperature of the radiator regardless of the room temperature.
It is important that the salt does not get into the central heating system. In an open or unvented system, if there is a leak, the water in the top-up tank for the central heating system will be automatically topped up with softened water, which will get into the radiators. This must be avoided.
If the central heating system or a radiator has been drained, and is to be refilled, the controls to the water softener must be switched over so that unsoftened water is fed into the header tank.
Inhibitor is a chemical mix that should be added to the central heating system water to prevent corrosion and prolong the life of the system.
Yes, aluminium can be put on a system with steel radiators, as long as an inhibitor for mixed metal systems is used. In reality, most systems are mixed metal, as many already have aluminium heat exchangers in the boiler, plus copper pipes and steel radiators.
