Can someone advise? Changed my sunvic select207 for a horstmann centaurplus c27. Had hot water last night but no heating- now have neither. Called plumber, he thinks it's an electrics problem. Old sunvic was clicking constantly that's why I changed. Please help!!!

Sorry, my crystal ball just fell off the table.
All you can do is follow the fault finding chart. Get your multimeter out.

I assume you have ruled out the obvious things like a tripped overheat thermostat, or a Burner at Lock-out?? otherwise only YOU know what you did to your wiring!!
