replacement for Danfoss thermostatic cylinder valve with pump switch?
I have been advised to replace the old Danfoss thermostatic cylinder valve but my old one has an electrical switch built in that switches off the central heating pump when the water reaches the correct temperature (ony when the heating is not running).
The closest direct replacement that Danfoss seem to offer now doesn't appear to have such a facility although the website suggests they can be used with an 'electrical interconnector'. but the web site does not seem to offer such an item.
The switch you require is now obselete, the only real alternative is to reconfigure the pipework using a diverter valve and standard cylinder thermostat.
