Hmm, ok I'll perhaps up it to 48 then. I can't see any wire, just this (excuse the dust)

That pic is the main screen. That is what is on the main screen, which I've just checked again and this is what is on the main screen. There is then the additional option under advanced settings under the *302 menu to change the heat pump DHW max temp which was set at 55 degrees which I've also reduced now to 46 to match the home screen. Seems there was some conflict there.

No - I'll adjust the temperature to say 48 degrees. I found the legionella setting it was down as disenfectent and I've now set it to do not use.

Re the water. These are the only options I can see. There is this with this setting currently set to use or 'Do not use' Then there is the max operation time which was set to 90 mins. And then there is the DHW Heat Pump max temp which is set to 55 degrees.

In perfect timing just went to look at ASHP and there is the error code below. Manual indicates 919 Error the set temperature for disinfection operation is not reached, or, after reaching, the temperature fails to continue for the requested time. I guess this answers the question re the legionella cycle then so the problem must like elsewhere. Edit - I have however found the disenfectent setting and it was set to Tuesday at 60 degrees for 10 mins. I've now programmed this to 'do not use' so it may have come on at some point earlier and tried to come on again.

Erm how do I check this? It does seem odd we used 6kWh in 3 days over the weekend and then 8kWh between yesterday afternoon and this afternoon. Our tank is around 380 litre as I recall, the large Gledhill.

I've no idea @AliG I was going to check the legionella cycle but there is nothing I can see in the manual that makes reference to this at all unless it's disguised as something else amongst all the waffle.

No we had that error a few weeks ago that it hasn't been done so to my knowledge it isn't working. And no yesterday there was no long showers hair washing or baths in complete contrast to the weekend which is what makes it even more strange. I need to see if the legionnaire cycle has come on when I can interpret the manual on where the setting is for this and I did see a thread about not many people using this as you suggest @joe90@Joe Ah I see. I do think our general usage is low then with that in mind.

Do you have solar to only be using 2kwh - I thought our general use was low with both of us working from home and laptops etc.

I just can't get my head around this. Yesterday (Monday) I took the meter readings of the heat pump and immersion so we were able to calculate we had used, since the same time on Friday 6.96kwh on the immersion and 94.78kwh on the heat pump over the 3 days. Strangely now at 24 hours since I took the readings yesterday I've taken a reading again on the heat pump and immersion and we have used 8kwh on the immersion since 3:30pm yesterday versus 6.96kwh on the immersion over Friday-Monday. Confused because I haven't actually changed anything since yesterday so I don't know why the immersion has used more in one 24 hour period than a 72 hour period over the weekend when we had baths etc. Any ideas anyone @AliG? On the plus on the 4 days since the readings I took on Friday I have a bit of a clearer picture now of our use which I can say over 4 days is seperated out as follows. Total units 162 between 3:30pm Friday and 3:30pm Tuesday, of which: 115 units is the heat pump 15 units is immersion 32 units of 'other' electricity use Averaging out our usage over 4 days just for the heat pump/immersion seems to come in at 32.5 kWh which is still more than others but recognise we don't have our EWI. Do you have a ASHP @Thedreamer as your usage seems to be far lower.

Thank you. I'll definitely look into this. Let's see what this week brings and we have a clearer picture of what our heat pump is costing now we have adjusted those flow settings. We have already seen our usage half in kWh over the last two days - if indeed the Samsung energy use screen is correct.

Is it a smart meter thingy that tracks energy use? Sorry idiot question but what is it exactly? We think we have a smart meter but haven't got the energy use thing.

I think that's what we have already. That's how I've been able to seperate out the usage. End two - blur light is immersion and one to right of it is heat pump.

Yeah I'll try that...

Ok I know you are all probably sick of me now. I don't quite know why I'm posting this but just for my own sanity at least it's out of my head. Alto have just rung. Apparently the energy usage screen on the heat pump isn't accurate and is only an estimation! I think this may be a bit of BS (but if someone tells me I'm wrong I stand to be corrected) but I'll monitor that but our figures suggest it isn't and is surprisingly accurate. They were quite dismissive about the flow rate temperature and indicated it will take longer to heat up so electricity use will be the same but based on the conversation on here and what I've read I think this is something I'm going to monitor and it's set at -3 as I think @AliG suggested so the flow temperature is slightly lower now Since we took the meter reading of the heat pump and immersion on Friday and again at 3:30pm today we have used a total of 101.74kwh split between 6.96 on immersion and 94.78 on the heat pump. Our total meter reading since Friday lunch and just now suggests we have used 122 units of electricity in total. Allowing for 101.74 on the heat pump that means we have used 20 units of electricity which when we used dishwasher and washing machine, dryer over the weekend as well as charging chain saws, hedge cutters etc since we were gardening seems pretty low and fits with what I thought our general usage was. I've also been on to Octopus about their tarrifs and Octopus Go and Go Faster as their day rate is cheaper than any other fix we can get and then any other cheap rate they can offer at night (or other times with Go Faster) will help us as we can time appliances etc and our electrician is coming this week to finally sort the solar too. This is literally taking over my life.....

That probably sounds about right then for our 'other stuff'. For a start asking them re the flow rate settings.

Ok right I need to check something. I took a meter reading on 7 January and it was 09359 and on 15 January it was 09945 it suggests we used 586 units of electricity during that time. Using the heat pump energy consumption setting I've found our daily kWh usage from that period. Granted on 7th and 15th that kWh on the heat pump is for a 24 hour period but in total it is 572kwh for those time periods (see bar charts below). If our total units of electricity used was around 586 for the 8 days (acknowledging I don't know what time of day it was on 7th I took the intial meter reading and was lunchtime on 15th when I took the subsequent meter reading) it suggests that our 'other' energy use was likely to be minimal. Does this sound right? When I rung Alto they were quite dismissive on the energy use of the heat pump and suggested we were likely using a lot of other energy elsewhere but this seems to contradict that point.

The wife thought it was this one but the instructions aren't entirely clearInstruction 10mm Wetroom (1).pdf

Neither of us can remember the make! We got it with the shower tray which we had off Facebook and it was new in the box sealed etc but the plumber binned the instructions!

No I don't think we have ridge ventilation. I'll ask them to check the loft insulation when they return and keep an eye out

Yes sorry they are literally all around the bungalow on the pitched (not on the flat roof part) we now have about 25 of them all evenly spaced. It's not 60cm thought it's more like 120cm.

So we raised this with the builder and some of these vent things were put in the fascias pretty much a couple of days after this post. Not seen anyone since due to Covid and I've just been up the loft and it's pretty much the same as it was in the first pic with condensation, so around a week ago? Should these have had some impact by now?

Quick question, just want to fit this flipper panel that the plumber didn't finish and as he had Covid. Can't find the instructions and just need to know what to plastic seal - are you supposed to cut a gap, fit the plastic under the hinges?? Is what he has done so far right or should he have cut a gap in the plastic seal?

Seems yesterday the energy consumption of the ASHP went down. I'm now obsessed on this function! And this is the setting we have set on the water law now which I changed yesterday. I also did what @PeterW suggested and changed the 201* settings to 10 and -5. We have turned the room thermostats up to 20.5 degrees though as 19 was a bit chilly for us.

Still in their boxes as our electrician needs to come back to sort ethernet cables and some sockets and I'm waiting for it to be done so I can do the comparison on both. Pretty much all progress has stopped due to positive Covid tests from a number of tradesmen linked to the builder and others self isolating.
