Hi, I have a Worcester Bosch Greenstar 24Ri boiler and I have got ripples on the heat exchanger, please see the photo.
What causes these ripples to form and does it affect the operation of the boiler?
Thanks for any replies.
they will know when it was manufactured from the "fd" no in the serial no. they also know that most are fitted within 3 months of manufacture. the boiler was probably registered with them by the installer so, either way they will know what year it was fitted.
as dan said you will have to address the sludge situation through an independant heating engineer
I think fixed price call out is about £270 and to buy the heat cell is lots more go for the fixed price but they wont guarentee it without you getting the system water sorted and it will ripple again if you dont
