Protherm 100EC combi boiler relay

Jan 09, 2006 2 Replies

I have had my Protherm boiler for about 6 years and it has now developed a faulty diverter switch relay twice. I am having no success finding a supplier of the part although I believe the same relay is used in one of the Glowworm boilers. The only identification numbers I can find on the relay are:


1650/1.0.00
220V240VT70
50Hz D0057
3600 CV8 GAS G20 20Mbar

CLASS 112H3+ No: 01021501265



28100EC15

Can anyone help please ? e-mail me : snipped-for-privacy@gmail.com
