He'll just need to learn the parameters.
Ok this is for mum. Who will get a subsidised install cause of a gov scheme. The guy doing survey said glow worm navien vaillant or WB. So we gonna select navien. I understand navien ncp come in 34w.. does this come in 1:10 modulation?Correct
The 40kW should therefore be a bit more efficient
Or you could be a Google warrior who doesn't know what he's talking about...Does that follow. ?
At the low output end of the modulation range the efficiency could be less than the efficiency at the high output end of the modulation range. Or it could even be the other way round.

It's a bit close to the ground - if it's dripping in the Winter and freezes it could potentially block the pipe with ice, leading to a dangerous situationOk the guy has been. My mum has a old boiler. Which has a copper pipe outside draining into drive. However we was told by other fitters this needs to be changed so it goes into a drain. However the person who came today said it’s fine...
Or I could be a friend of a chap who designed heat exchangers for a variety of industrial applications.
Why was it suggested by some other Instalers that under new regulation. Given I didn’t have a drain nearby. I need a pump to take it up wall into the garage void and down behind the washing machine into the waste?It's a bit close to the ground - if it's dripping in the Winter and freezes it could potentially block the pipe with ice, leading to a dangerous situation

I’m probably not phrasing my self properly. A previous 2 installer said would need to condensate with a pump to a drain pipe as we didn’t have a drain nearby. While the recent installer said we didn’t (and we can just use existing drain off point- changing it to plastic) - not sure why he said this when I thought condensate pipes had to be near a drain or limestoneIts copper and can't be used for condensate drain.
