Worcester Bosch Heatslave oil fired boilers - flow switch problems
 

Following a serious flood due to the flow switch failing in the
Heatslave boiler, have other people have had the same problem? This is
a component which I am sure has been redesigned perhaps through similar
disasters in the past yet Worcester Bosch are 'unaware of any
inherent fault', which I cannot believe and I have heard of at least
three similar tales of woe. Despite other components in the boiler
being rigidly plumbed in metal, this is a plastic device which can only
have a limited life.
