Just been told this morning that I need to replace the Turbulator on my Powermax 155 This is 4 weeks after having a British Gas Engineer do a service after a breakdown and replace the Burner Gasket. (and 6 months after the boiler was serviced by the previous occupant and me buying the property)
Should this Turbulator fault have been picked up/noticed at the service 4 weeks ago?
Any idea what the costs are involved for this additional repair?
There are actually eight turbulators (spiral metal rods - see here: www.directheatingsupplies.co.uk/powermax-turbulator-p626) inside a Powermax 155, which are supposed to improve the flow of heat from the burner throughout the water cylinder (although they're not in direct contact with the water). Recommended exchange periodicity is every seven years, I understand. They're not expensive (around £20 each), but it's not an easy job to fit them - you really need someone who's used to servicing Powermax boilers. Not replacing them won't stop the boiler working or create a safety hazard, but will make it less efficient.
As to whether it should have been noticed before, you'll have to take that up with those involved - but again, someone unfamiliar with Powermax boilers probably wouldn't realise it needed doing.
