Heatslave 20/25 Flow Switch

[BrynRovers]

Fed up with Worcester Bosch spares costs.

I have just replaced the flow switch with one from RS Components, got it on eBay for a fiver.

The Worscester switch costs in the region of £70 but a new one of these from RS costs £35 and FAR better quality. Works a treat.

Minimum flow rate is 3 litres/minute which is ample if you have a reasonable water flow.

Fitting only needs a small modification by fitting a 22 - 15mm reducer.

Part number is 256-578

I am not sure what prompted you to want to tell us all about that.

But it does give me an opportunity to point you to a video showing how they can leak!

Bryn - I use a Grant Vortex 26 Combi flow switch straight swap, but you have to cut off the plug on the worcester unit and crimp it onto the end of the Grant lead (the grant ones don't spray water from the electrical lead either ...and cheaper

I posted it because I was fed up with WB's extortionate prices for spares.
Thanks for the U Tube video anyway, part of the learning curve.

I will look at the Vortex switch to see the price difference. Thanks.
Been thinking of fitting a pressure switch instead of the flow switch.

Anyone know of a replacement equivalent Pressure Vessel ???
