Looking at a booklet that I have on the tank its described as a unvented Hot Water Cylinder which can have up to three water coils.

Yes that’s what I did , well it doesn’t go to that, only 55 is max and that hasn’t helped , 45 circ temp just now and DHW 40 . Switching back to fifty.

A bit of pressure on here to get the hot water up for a bath come Midnight otherwise it’s in the ear! Do I put circ temp back to 50 c and hope the water gets up to that .

Yes that is the circulation temperature, water is shown at the tap symbol . The circ temp is feeding either the heat temp for rads or water but not both.

The temp is reflective of what is indicated , but I will measure it. It’s a temp signal your seeing which then indicates the circ temp

The small icon is a defrost symbol , which I didn't notice taking the pic.

Ha, they are cold just now as no requirement for heat but monitoring.

The temps are from the controller GEN 5

4hours on Circ. 49.6 Hot water 39.6 . Just saying. Outside 1.8 c Radiators on 20 c NOT CORRECT . I will leave 55 flow and 48 DHW FOR a while.

Ha, they are cold just now as no requirement for heat but monitoring.

To determine the switch over then ,there should be no heat icon showing at top right of controller , would that be correct , similarly the water tank symbol should not be active if rads/heat is on ?

Ah OK, so no underfloor heating here. I will try and check that . I don’t know if this helps me or you guys.

UHF ?

So Midnight after setting the flow to 55 degrees which is maximum with no hot water used the House 21.4 Outside 3.8 Hot water 39.2 Circ. 48 degrees Bath run ! Morning - House 8.30 21.5 Outside 3.8 Hot water 39.8 Circ. 41.5 Something not right. What else. I will check parameters/field settings.

Didnt see the vans often enough lol.

So original plant was two pumps , not required they said , sold 9kw , reset 16kw with larger copper flow pipes instead of plastic, and further from wall. , better insulation , magnetic filter and glycol in fluid , plus a number of small things........ nightmare . Well you would wouldn’t you if you thought , finally it might work properly.

Ok , so I’m watching Smart meter!

Yes to be blunt , they agreed to take the system on with the approach of Freedom Pumps , charged me 4500 to correct the system installed by a Central belt company who went bust a year after install , and when I asked them to service it and find out about a fault it had E920 if I recall , they said they didn’t know enough about Samsung , so I didn’t phone them again!

Thanks Guys , once again , who is right about cylinder , I have no had any comments from an ashp service local to here or Black isle renewables , who have washed their hands to repairing or looking after this. I have set the flow to 51 and cylinder to 49 , so will see what happens. I will look at manual for clues.

So continuing my circulation and hot water temp being low , anymore suggestions apart from getting a knowledgeable ASHP Engineer! You guys are the first to following up my particular problems and I cannot thank you enough. I will post 3 further pics of my insulation improvements and water tank specs. I thought I posted comments a wee while ago but I think that’s disappeared.

B and Q , have options . Am I missing pictures of what you are talking about?

Ok to add , I’ve just spent 2 hrs tidying and doubling up at joints etc with the spare foam lengths and a lot happier , not a Bonnie sight but more secure . Thanks for the prompt ! Apart from needing a beer from the floor insulation on the throat haha! just read the thread on cold in the attic , perhaps there is some over all blanket I can put over bothe tanks and immediate area?
