Unvented Hot Water Cylinder Servicing and Repairs in Hatfield
Understand your hot water setup before booking
Not sure whether your Hatfield cylinder is heated electrically or through the boiler? A photograph of the model label and the surrounding installation helps TNG Services discuss the system and the servicing or fault investigation you need.

Explain the concern

Agree the work
Discuss the visit and any proposed repairs before additional work proceeds.
Showing the single result
Direct and indirect systems need different context
A direct cylinder normally uses electric immersion heaters. An indirect cylinder receives heat through a coil, with an immersion heater often available as another heat source. Your particular arrangement should be identified from the appliance and installation.
Tell us which heat source you normally use and whether the problem occurs on one mode or both. Avoid changing internal wiring or controls to test a suspected fault yourself.
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 I enquire without knowing the cylinder type?
Yes. Send clear photographs of the label, cylinder and accessible controls, and explain how you normally heat the water.
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 Hatfield, 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.
