@editor @mikef For Comparison I have a Viessmann Vitocal 151-A which will have been installed 2 years next month. So far... Compressor Hours 5804 and Compressor Starts 3579. On that basis I should reach 20000 starts in c.11 years. I've no idea whether these numbers are good or bad. I asked the service engineer about it last year and he mumbled something to the effect that as long as the number of Compressor Starts is less than the number of Compressor Hours then I'm doing ok!

@gc61 Less that one start per hour is very good, our pump can manage that when its cold, but it cant modulate down low enough in Spring and Autumn, even with a 9 hours setback.
