Solar water heating repair

Solar water heater repair and service

No hot water, a leak or a pump that won't stop? Our technicians troubleshoot and repair most residential solar water heaters, including systems installed by companies that have since closed.

Clear diagnosis before any repair.

Common problems

Signs your system needs a visit

Little or no hot water

Often a failed pump, sensor or controller, and usually a straightforward repair.

Leaks or drips

From collectors, fittings, valves or the tank. Worth fixing early to protect your roof and ceiling.

Noisy or always-on pump

A pump running at night or rattling usually points to a controller or sensor fault.

Controller errors

Blank screens, error codes or wrong temperatures can often be fixed without replacing the system.

Freeze or storm damage

Cracked collectors or loose mounts after a cold snap or storm need a careful inspection.

An ageing system

Older tanks and collectors can often be serviced or partly replaced instead of fully replaced.

Reviews

From a repair customer

Our solar water heater was installed by a company that closed years ago. Luis found the failed pump in an hour and had it fixed the same week.
