Ferroli boiler repair & replacement

Modena, Optimax and Domina repairs and replacements.

Ferroli boilers

Working on Ferroli in the West Midlands

Ferroli is an Italian brand fitted heavily in UK homes through the 2000s, particularly Modena, Optimax and Domina units. We still find plenty of them across the Black Country.

They earned a reputation for troublesome PCBs and diverter valves, and parts for the older ranges are now hard to source. We'll always check availability before we take money for a diagnostic on an older Ferroli.

We cover Halesowen, Dudley, Stourbridge, Birmingham, Solihull, Wolverhampton, Bromsgrove, Kidderminster and the wider West Midlands.

Ranges

Ferroli models we see most

Modena / Modena HE

Very common 2000s combi. Parts becoming scarce.

Optimax / Optimax HE

Condensing combi range with known PCB issues.

Domina / Domitech

Budget combis widely fitted in rentals.

Bluehelix

Current range — better built and properly supported.

Common faults

What goes wrong with Ferroli boilers

PCB failure

The classic Ferroli issue. Boards for older ranges are increasingly hard to get.

Diverter valve sticking

Heating warm when you only want hot water, or lukewarm showers.

Ignition lockout

Gas supply, electrodes or condensate — same checks as any condensing boiler.

Pressure loss

Expansion vessel or a leak. We pressure-test rather than repeatedly topping up.

Repair or replace

Our honest view

Current Bluehelix units are fine to repair. Older Modena, Optimax and Domina boilers are the ones where we most often advise replacement — you can spend £300 on a board and still have a fifteen-year-old boiler.

We replace Ferrolis with Worcester Bosch Greenstar or Viessmann Vitodens, with a full flush, magnetic filter and up to a 12-year guarantee.

Our diagnostic visit is £99 inc VAT and it comes off the bill if we carry out the repair. You get a fixed price before we touch anything — no hourly rates and no surprises on the invoice. We’re Gas Safe registered, Which? Trusted Trader endorsed and rated 4.9 across 206+ reviews.

Ferroli questions we get asked

Can you get parts for an old Ferroli?

Sometimes, but availability is genuinely poor on Modena and Optimax now. We'll check before you pay for a diagnostic so you don't waste money.

Is a Ferroli worth repairing?

If it's a cheap part on a newer unit, yes. If it's a PCB or heat exchanger on a 2000s Modena, replacement is almost always the better spend.
