What this means for your next step

Working hot water does not show that the heating controls, circulation or room circuits are working. Record whether the problem affects every radiator and whether the controls show a heating demand. Avoid assuming that one named component must have failed.

No heating but hot water: start with observable facts

Record the exact symptom

Note what the appliance or heating system is doing, when it happens and whether anything restores normal operation. A practical homeowner guide starts with evidence, not guesswork.

Identify the appliance

Keep the make and model available from an accessible label or the appliance documents. Do not remove the casing to find identifying details.

Avoid repeated resets

Record the displayed code before resetting and avoid repeatedly restarting the appliance. Repeated resets can hide useful fault history without resolving the underlying cause.

Checks that may matter for no heating but hot water

Appliance condition

Visible condition, controls, operating behaviour and service history help the engineer decide which safe checks are relevant to the reported issue.

The connected system

Boiler pressure, circulation, emitters, valves, ventilation and the flue route can affect performance. The relevant combination depends on the appliance and symptoms.

Clear findings

A useful outcome separates observed facts, likely causes and confirmed faults. Any extra work or parts should be explained before the appointment scope changes.

Prepare a useful no heating but hot water enquiry

Send the essentials

Include the full postcode, appliance make and model, fault code, current heating and hot-water status, and the best contact number for access.

Make access clear

Explain tenant arrangements, parking restrictions and obstacles around the appliance, meter, controls or radiators so the visit can be planned properly.

Verify before work

Ask to see the Gas Safe ID card and check that the category listed on the reverse covers the appliance and task being discussed.
