Unvented Hot Water Cylinder Servicing and Repairs in Hitchin
Separate a maintenance visit from a repair
A routine service and an investigation into a leak or heating failure have different starting points. Tell TNG Services what is happening at your Hitchin property so the request can be discussed with the existing fault clearly identified.
Identify the system
Share the cylinder model, heating arrangement and any service records.
Explain the concern
Tell us whether you want routine maintenance or help with an existing fault.
Agree the work
Discuss the visit and any proposed repairs before additional work proceeds.
Showing the single result
Report a leak by its visible location
Water near the cylinder could come from more than one component. If it is safe to do so, photograph the visible area and describe whether the leak is constant or appears during heating.
Keep clear of wet electrical components and do not attempt to seal or cap a safety discharge. A photograph can help explain the request, but identifying the cause requires an appropriate assessment of the installation.
What can a cylinder service involve?
The service scope follows the instructions for the particular appliance. It can include inspection of the cylinder and accessible connections, checks of relevant controls and safety components, and attention to the expansion arrangement. Cleaning or further component work depends on the model and findings.
Different cylinders manage expansion differently. A visit should account for the installed design rather than assume an external expansion vessel is present. Any defects or repairs needing further work should be explained separately.
Routine maintenance
Share the last service date if known. Annual maintenance is commonly specified by manufacturers; check the instructions and warranty terms for your own model.
An existing fault
Describe loss of hot water, leaks or discharge when enquiring. Routine servicing does not automatically include diagnosing and repairing every reported problem.
Before arranging your cylinder visit
Can a photograph establish which part is faulty?
It can help describe the concern, but it does not replace inspection or establish that a particular component needs replacement.
Is this the same as a boiler service?
No. The cylinder stores domestic hot water and has its own maintenance requirements. A separate boiler service does not automatically cover the cylinder.
Can you quote from my enquiry?
The model, access and scope influence the work. Send photographs and fault details so the next step and proposed charges can be discussed.
Before you get in touch
Include your postcode in Hitchin, a photograph of the model label and a wider view of the installation. Describe how the water is heated, when the issue started and any previous repair work. Please do not remove covers or dismantle components for photographs.
