We’ve got a vaillant ecotec boiler which is working well although about 15 years old. Only 1 part replaced and regularly serviced
our thermostat is very temperamental and I’d like to replace it, the battery cage constantly slips down which is causing issues
do I need a plumber or an electrician? Anything I should ask?
the current one is a Drayton digistat 3 and we do use the 7 day programme feature
also any idea of cost? Thanks
