Good if you need it as a 1:1 replacement.
Purchased to replace a this exact part that has failed after 5 years.Due to it just bolting to the plumbing valve which was still working fine, it made for a strraghtforward 1:1 replacement without having to call out a plumber over Christmas.The new one is almost silent in operation, which threw me a bit when testing!Hopefully this lasts longer than the original.

Straight Replacement for Sunvic Head
Awesome delivery speed, and quality of item is legit. I have a S plan system with a megaflo and this will sit on a two port valve body. After scrutinising the wiring diags of both heads, I could see that the 4 wires did the same thing and connected to the same places so a straight swap into my wiring hub.The old Sunvic head although on the surface was functioning correctly was letting voltage through and calling on the boiler even when the CH and HW were both off.I diagnosed the issue by turning off HW and CH on the thermostat (a NEST) and although the CH and the HW valves were closed (correct positions)... The pump was still running and a call for boiler was displayed on the boiler front panel.By removing the switch live (orange) from the valve head into the wiring hub it immediately dropped the demand on the boiler and the pump powered down.Our pump was running mostly 24/7 before and the boiler was firing. Now outside the HW and CW programme its total silence from the boiler cupboard ! Thank You God !
