sorry to say with the set up you have you cant have independent heating temperatures as that one dial does both your hot water and heating
so it needs to be around the 65dc temp

Oh, i didn't know that. Is there something that can be done to change that?
unless you add the diverter kit and change the piping no sorry or theres anther way but will requires piping changes and more items
Thats a pain in the backside, wasn't told that dial also controlled the hw. I was told the stat on the cylinder determines the hw temp?! What would the likely cost of a diverter kit be?
yea sorry to say around the £200 mark just for the diverter kit ish
and then for someone to pipe the hot water cylinder direct to the boiler

😡😱😵 oh...
May just have to leave it then - it was already more than budgeted for!

if you dont mind what have they done and roughly how much?
Move boiler (not that far, other side of wall) 1 new rad, 8 trv's, ?mag filter?, take of all rads and wash/flush out with pressure washer as opposed to system power flush. Nest stat. Took from around 730am to 6pm, two ch engineers plus a spark. £3300.
a tad on the high side i would say but cant comment as havent seen the job
Contacted 4 ch engineers. One had to reschedule except never made another time to come round. One said he would be round and never turned up. One would like me to believe he was the second comming of Christ and there was nobody better that him; he never bothered to send me a quote. Then there was this company who did the job. All four recommended by others.
Does this mean that say during the summer we dont have the heating on, we wont have hot water? if i switch the hw on via the nest will that heat the water only without heating the house, if that makes sense.
you should be able to just have how water on
you should be able to control the hot water from the nest
you do have a two zone nest ?

Its a 3rd gen nest, which lets me put the ch on and set temp etc and also have hw on/off/boost. Is that 2zone?
yes it is
might be worth a try just putting hw on and see if any of the rads heat up because i cant see any port valves in your pics (normally by the cylinder)

Ch has just been on so will give that a try in the morning. What is the function of the port valves? I just want to be more informed when i get the company back in so they dont try and fob me off - not that i have reason to think they would.
to direct the hot water from the boiler so it heats up what you want eg you turn heating on hot water doesnt come on as well unless its set for it to come on etc
Ah ok. I will see what they say tomorrow and let you know. Thanks again.
For that money you should have got seperate switching for heating and hotwater what will happen in the summer months is there any motorised valves i cant see any in the pictures ? . kop
I spoke to the installers and they are going to come rpund later to discuss but to have the diverter kit and port valves installed will be just over £300. Up this way prices are inflated with everything sadly.
Would this be a worthwhile outlay to have these installed?

I can't answer that only you can
Apparently, if i keep the ch dial at 3 this should produce water at about 50dc which would be too hot to bathe/shower in...the temp produced by keeping at setting 3 is definately not too hot.
Your stored water needs to be set to 60 so if you set your boiler temp lower than that it's never going to get upto temp
Also there's a very high risk if the water in your cylinder is below 60 bacteria will start to grow
Thanks for that. I will let you know how i get on with the installer.
Installer came over to look at system. Suggested turning dial to number 4 if 3 was too cold and 5 too hot! I explained that we want the touch temp of rads to be low but the water to be hot hot. A diverter valve was discussed but i didn't realise this then makes 'hot water priority'. So if on a cold day the heating goes on and detects the hw cylinder is 5dc lower than it should be then it gets the heat before the rads.
Cant there just be a simple solution. We want to run the hw and ch independently and at our choice (with none having priority unless we decide to put hw on without ch etc).
It maybe the case the stat on the hw cylinder is faulty. Temp of hw at tap is 30dc after the boiler has been on plenty at no 3. The boiler displayed 47dc at max on no 3.

The hot water prioritie would only work when the hot water time / program is calling
There is a way but requires a bit of setting up eg mixing valve / blending valve
Don't forget about your heat loss through pipes / air
