"Combi in a CW2 detached kept dropping performance. Diagnosed a heat exchanger caked in scale, descaled, fitted a softener with kitchen bypass. Feels like a new appliance."

What boilers in Crewe actually look like right now
Crewe railway-terrace stock carries 12–16 year Baxi and Potterton combis; newer estates in Wistaston and Willaston have 6–10 year Worcester and Ideal Logic units.
Crewe boiler-repair work leans toward Baxi ignition failures, Potterton PRV weeping and Worcester Greenstar diverter faults. Access on railway terraces is often tight, and we photograph before quoting labour.
Crewe water hardness & magnetic filter advice
Local hardness: Hard (typically 220–300 mg/L CaCO₃) — full Cheshire aquifer supply.
Water is moderate to hard (150–200 mg/L). Magnaclean plus scale reducer on any repair on unprotected combis is the standard call.
The 5 boiler faults we see most in Crewe
- Baxi ignition failure

- Ideal Logic F1 (Willaston)
How Kevin approaches a boiler repair in Crewe
- Photograph access before quoting labour on railway terraces
- Carry Baxi ignition kits and Potterton PRVs on the van

Why you shouldn't be sold a new boiler in Crewe without a proper diagnosis
Crewe customers get quoted for boiler swaps on "parts obsolete" verdicts that are false. Baxi 24/28 and Potterton Puma spares are still widely available — check the part number first.
Our promise on every Crewe boiler-repair call-out: £50 to attend and diagnose, a fair fixed quote in writing before any billable repair starts, and the £50 refunded if we can't fix the fault.

Recent Crewe customer reviews
"Old back boiler and fire finally gave up. Decommissioned safely, fitted a combi in the kitchen, certificated, made good. Fair fixed price and £50 diagnostic came off the bill."
— Gareth P., West Street · Back boiler swap, West Street
"Cylinder immersion had been on since the seventies. Replaced element, thermostat and eventually the cylinder itself. Clear written report, no upsell."
