I have just inherited a powermax 155x with my new house and I know they are a pain!!! Does anyone know why I have cold ish dhw and nowhere near the 18l per min stated in the mi's . I suspect it to be the blending valve has anyone else suffered this problem. thanks

could be blending valve. dont touch it as they leak if you look at them the wrong way.

get these serviced properly too. id recommend the manufacturers over anyone else. its a baxi company so it will probably be heatteam that do it.

I am sure that someone has had a failed blending valve at some time and somewhere!

Have you measured the temperatures at the three ports to the blending valve???

Well I've had well into double figures, you could try to adjust it but the actual adjustment is done beneath the black plastic head. They fail alot though.
