Look under "covering an eps plinth" there are photos on there. I used the Ubiflex on top of blockwork and it looks really smart

Alot of us have used Ubiflex and it looks really smart. Put this is the search engine on here

I'm not as lonely in this world as I thought!! Thanks chaps

How do you do that partial quoting of what people have said instead of their whole reply please? (Top Luddite here!!)

We had a log burner in our previous home and it was lovely but I had insulated the old cottage that much when we lit the fire (5KW) it used to send me to sleep! Every day is a learning day! I had the number of the tech guy who stat I was using and after a call just now he is sending me an updated sender unit that is more suited to my house with a greater degree of hysteresis and a degree of self learning so what a great service that is.

I think this is the problem with your house and @ProDavein that you have log burners and this will add considerably to your heat input and thus reducing your heat pump usage compared to my house which has no log burner. My stat has a .5 degree increment but the temp of the house goes nearly a degree over the set temp if I do not turn it off manually. I have not introduced any heat into the house for over 24 hours and the temp inside has not dropped at all in this time

@jackruns his at a low temp and I think I need to try this. I am starting to understand my new house but because you do not get instant feed back from any changes you make and no two days are the same weather wise then you a few variables to contend with can confuse matters. My heat pump does seem to defrost quite regularly so not sure how to combat this or whether my heat pump is prone to this? Have you always run your temp so low or have you had them higher and then reduced them once you got used to the house? With you saying the house is slow to react because you have such low temps does this mean the heat pump is running longer to maintain a constant internal temp?

Glad to hear (in a nice way) that other people's heat pumps are icing up as I only have experienced mine for two weeks and it seems to ice up regularly and I thought I had problems that I did not know how to sort out!! Glad you got yours sorted @joe90

We visited a Passive house before starting on our self build and on the day we went it was 19 degrees inside but felt cool so we decided to put ufh in our Passive house so we had a heat source

We have no heating upstairs but now and then it would be nice for some additional heating in the bathroom but as we have mvhr would this not be distributed throughout the house and not just warm the bathroom?

Disappointed you did not ask me to help you Ian, could have got this from Morecambe Fire Station if you had only contacted me!

I realise this but have two rooms to finish plastering and then I can finish the balancing. The way I am shaping I will break that record easily!

Right just an update on all things mvhr. Massive difference to the drafts now the unit is running at 20% instead of 30% so not as much air being moved around and the house is staying warmer for longer without the need to have the heat pump on. The house has stayed at 19.5 degrees for nearly 24 hours without the heat pump coming on so I am gradually getting my head round the way things work.

Here is our walk in wardrobe. I built this myself from IKEA kitchen units and a local granite supplier for the tops. The hanging area is IKEA black panels with Magnet/B&Q hanging system. Not sure of overall cost but around £2000 with no labour cost. The units are kitchen quality so have self close and rigid drawer runners. Granite will last anything my wife can spill on it and the hanging area looks really smart for not alot of money. Sorry photos aren't brilliant.

You started it!?

No, no and no but thanks for the idea. Feet up and tools are put away (at the mo)

No doors involved. I think it is like my ASHP and getting it set up right but it is not my forte being patient!. I have reduced the normal airflow to 20% rather than 30% and this has made a difference

If you want to fantasize about me Ian feel free as I have enough on my plate trying to do technology than worry about your needs!! In fact after 3 years it is bloody marvellous to be sat having a coffee and trying to switch off all things self-build in my mind!!

Yes. My head is absolutely mashed at the moment and I am struggling to get my head round all the new technology ( I am nearer 60 than 50). I have a pile of booklets relating to mvhr, ashp, shower controls, ovens, tv's, etc and it is mind boggling. The mvhr is bad enough but I have managed to reduce the normal run rate to 20% and this has made a difference so will wait and see how this goes. Feeling cool/cold air is not what I expected but may be this is the norm, what do other people experience is what I am trying to understand as I have nothing to compare it to?

More moving questions folks!! Whilst sat having my coffee I notice you can feel air movement around my feet. It feels like a draft and just wondered if this is the norm with mvhr? Where I am sat is in a space from living room to large open dining/kitchen and the supply air comes into the lounge and the extraction is in the kitchen. I new it would flow this way but did not realise I would feel a draft. The mvhr is a vent axia sentinel which I have just switched on and not balanced yet. It shows 30 to 35% fan speed so i am going to have a look at the setting up controls but just wondered what/how people have set theirs up? I have also noticed that the supply vents feel cool when I put my hand near them, is that normal? I know most people run them on a really low setting but some experiences would be beneficial to understand how to run ours. TIA

Thanks, I understood you but explained it wrong

I have checked my system and my HW usage is similar to yours. May have to monitor it like @jackhas suggested and see how I get on. I have lowered the stat temp to 20 and see what that does and go from there. May be a month of tweaking here and there. When your heat pump is on what temp does the flow get to Dave? @jackis suggesting lowering the temp for 24 hours and see what that does. The trouble is it is not like a boiler and you see instant results, with our type of house it takes a while for it to respond. The temp does not drop to much over a 24 hour period but one day it may run numerous hours to get it to rise one degree and the next run twice as long to raise it the same amount. My stat has 0.5 degree increments so not precise enough to know what the exact temp is and how far it has risen in a given time.

I know it is kWh. Yes the house is Passive just not certificated. 400mm Eps in the slab, walls 300mm and warm roof 400mm. I assume it is defrosting as the fins are covered in ice and then they are not!!

Floor covering is Porcelain tile throughout so no problem there. With the unit running a lot it is defrosting frequently as every time i go outside it is defrosting so tend not to go outside to much!!

It is a Panasonic Aquarea 9kw and the flow temp is set at a high of 35 for heating and 48 for HW.
