Aparanetly a de stratification pump needs to be fitted. I have no clue what this is but the plumber wasn't happy when he was told.

I was unhappy leaving it so have left them with just the immersion heating the water. I'm waiting on a call from Telford technical to see if they can shed any light on it. No offence taken, I'm aware of the dangers of unvented cylinders and have wired many over the years and seen enough DIY...

Stat is 25-65 degree it's is 100% wired correctly.

definitely wired correctly, as i said the stat was operating with the heat from my hands.

its definitely a horizontal cylinder and has been installed correctly, as per instructions, although i didn't do the plumbing only being a lowly electrician. its a dual stat with an upper limit cut out combined. it has 2 probes out the back that sit inside the cylinder pocket.

at the bottom, my thinking is it isn't getting warm enough to be satisfied but have not idea how to remedy it.

stat constantly calls even though HW is raging hot but when i remove the stat it clicks off from the warmth of my hand.

system boiler, unvented cylinder through a 2 port valve controlled via a programmer and non functioning thermostat.

Wiring up a system with 3 zones 1 for UFH 1 for Traditional rads 1 for HW first 2 work perfectly, Thermostat for HW will not operate when placed in cylinder pocket but clicks on and off when held. Any suggestions as to fault would be appreciated.
