My new boiler in my new house will be 1 year old in january, it needs servicing in 12 months every year from new to keep in with the 8 year guarantee. I have always had my boilers serviced in late summer, heating engineers get rushed off their feet in mid winter. I have had it serviced 4 months early, a week ago, lately found out that a 2 way valve was a bit stuck after being static all summer, was shown how to sort that. So now I am fully ready for winter. I asked about the condensate pipe, mine runs inside so no chance of it freezing. Check where yours is, man told me about rip-off plumbers called out last year, charging £100 to just de-frost the condensate pipe. All it needs is a kettle of hot water
Now I am tweaking temperatures in various zones, these new houses have zones and many have underfloor heating. You have to get close up to the thermostats to be able to read them, I am setting them once and for all, doubt I will adjust them all year, nice and cosy for me and it kicked on downstairs today at 5am. Got to allow for the ufh to take quite a while to warm and then cool
