Sime Boilers: Format and Murelle Range
Sime is an Italian brand with a modest but long-standing UK presence, and we occasionally come across the Format and Murelle ranges on service calls, usually in properties where the boiler has been in place for some years..

How the range is built
Sime's domestic ranges follow a fairly conventional combi and system boiler layout, without unusual construction that changes how we approach a repair.
What we see go wrong
PCB faults and pump failures are the typical issues we find, consistent with any boiler of similar age reaching the end of its component lifespan.
Servicing and parts
Sime's smaller UK footprint means parts can take longer to source than mainstream brands, and very old models sometimes require reconditioned components.
Questions we get asked
Is Sime still sold new in the UK?
Sime has a smaller UK presence than the major brands; we can advise on current availability if you're weighing up a new installation.
Why is it taking longer to get a part for my Sime boiler?
The brand's smaller UK distribution network means some parts are ordered in specially rather than held locally as stock.
Should I repair or replace an old Sime boiler?
We'll check the fault and parts availability first and give you a straight recommendation rather than assume replacement is needed.
