Central heating systems

Whether you need a new central heating system installed or repairs and servicing, C J Walsh Plumbing & Heating Ltd can help. Get in touch today for central heating services in Stevenage and throughout Hertfordshire, Bedfordshire and North London.

In order to keep your heating system working efficiently you need to stop the build up of sludge caused by the natural rusting of radiators internally. This causes blockages in the pipes, valves and boiler which reduces the water flow leading to costly repairs or replacements.  


C J Walsh Plumbing & Heating Ltd offer a power flushing service using specialist machines and chemicals to free your central heating system of this sludge, extending the life of your boiler. Call us now for power flushing if you are experiencing any of these problems with your heating:

• Slow to heat up

• Radiators need frequent bleeding

• The pump is excessively noisy

• Partially cold radiators

• Leaks

• Dirty water in the radiators


We cover the surrounding areas of Stevenage in Hertfordshire, Bedfordshire and North London.
