Heating Fault Finding & Repair
Systematic diagnosis and repair of heating system faults
About This Service

At Halo Heating, we take a systematic approach to fault finding — using professional diagnostic tools to pinpoint the exact cause of the problem, rather than guessing and replacing parts unnecessarily.

Frequently Asked Questions
My radiators are cold at the bottom — what does this mean?
This is usually caused by sludge buildup in the system. A power flush can restore heat distribution. We'll diagnose this on the visit.
My boiler keeps losing pressure — is this serious?
It could indicate a leak in the system, a faulty pressure relief valve, or a failing expansion vessel. We'll find the cause.
My boiler is making a banging noise — should I be worried?
Banging noises (kettling) are usually caused by limescale on the heat exchanger. It's worth getting checked to prevent damage.
Can you fix smart thermostat issues?
Yes, we work with Nest, Hive, Honeywell, and other smart thermostat systems.
