That's good to know! I've just gone back to the plumber actually to get the price difference for the 5kw so I can actually compare. I know the list price, but with their package discounts it gets confusing.

Thanks! Do the tanks 'top up' the temperature though, so you have the feed from the ASHP but you can store it at a higher temperature? Then mix this hot with cold to get a usable temperature. I am not sure if that's an efficient thing to do but I had thought that would get us around the small tank we have

Thanks ProDave, does yours do DHW in the bathroom too?

Thanks Joe, I had seen this from you before and had made me confident in the 5kw one, I guess the difference is our insulation won't be as top notch as yours. I forgot to re-mention we are doing a barn conversion . I haven't seen any second hand ones I have felt confident in yet, and time is ticking so might be just going new!

Hi all. I have been planning to get a 5kw ASHP but our plumber suggested we get a design done by the plumbers merchant here as it was free. It seems they are suggesting a 7kw pump. the house is about 65 square metres split over two floors. We have a telford tempest 200L heat pump cylinder to go in, and underfloor heating in the ground floor, nothing upstairs. We will also eventually have a woodburner downstairs for occasional use There is one main bathroom with bath and shower over, and then a second shower room in a garden studio, which will only be used very occasionally. I've attached our draft sap - I actually can't remember what plan we had for heating at the point this was done, not sure if ASHP was on the cards then, I think we has just said we would use oil. Can anyone shed any light? Budget is quite tight so I don't want to size up the ASHP if it isn't necessary. thank yooou! EAC 040-SapDesignDraft-TrevathanBarn,Redruth (1) (dragged).pdf

oh yeah forgot about that one! They might come up similar. I'm guessing it would be fine to use these with a wall hung frame as long as they are fixed correctly, I can't figure why not

Is there any reason I couldn't use this cistern? It's designed for back to wall, but if I fixed it as if I was using back to wall, and then used the wall hung frame you posted... this one produces the best height I have found so far https://www.qssupplies.co.uk/bathroom-furniture-shower-taps/180168.htm#

@Temp thanks will take a look into it

well you're a better googler than me!!

Thanks @PeterW @Temp Do you think this would only work for a floor standing toilet rather than wall hung ? I guess I would need to build my own fixing frame for wall hung as the standard ones put them high, which seems tricky

Thanks Temp! They all seem to have roughly the same flush pipe height which is good to know. So I guess it's whether the pipe itself can be shortened maybe.

Hey Peter, thanks! would it not end up the same height because of the height of the flush pipe? Or can you alter this?

(the concealed cistern I have posted about before is at my mums place... this is for mine!) So I had in mind to do something vaguely like the attached picture, and I would really like to have the basin countertop at the same height as the toilet boxing in. However, the shortest concealed cisterns with frames I can find are at 0.82m in height, which is quite high for a sink shelf no? As shallow sinks seem to be around 15cm high, so would make the top of the sink 97cm which seems high? Even without a frame surely it would end up at the same height because of the height of the pan and flush pipe? Can anyone shed any light on if this can be shorter, or if this sink in the pic is likely to be at 97cm? Plus the wood board so maybe 99cm I see the countertop furniture units you can buy off the shelf are about 75cm high as standard, making sink height 90cm. Maybe an extra 7-9cm isn't that big of a deal?? I don't know! I know you can have the inset sinks but that's not the current aspiration.

Thanks @PeterW @Onoff @Nickfromwales Should I empty the cistern first before taking off the flush pipe ? We have soft water here, but some crap might have gotten in there at some point, I'll check!

Any plumbers fancy explaining the fix for this to me? I have looked on youtube!

It's not there yet, so I might be able to make that work actually!

I could run it a little way but not sure I would get around the corner, I'll have a look!

Is there a maximum run a dishwasher waste can run? Can you get extenders? I need to run around a corner and haven't got the dishwasher yet so not sure about the hose length. And am I right in thinking it doesn't need to follow the same fall guidelines as normal waste? And it can just pop straight into this if I fitted this ready for it? Thanks

OK I'm back!! Ignored this problem for too long I did take a video of this but can't seem to find it. However, my further details are that when you flush the toilet, it now continues to flush and empty the cistern, unless you press on the big white cylinder in the middle, then it stops. Any clue how to fix it?

I can't seem to find the information online when searching things available to download. It's 3.5m horizontally and say 3 metres vertically between the two! So roughly a 6.5m run

Thanks Peter. What is MIs? I've tried looking at online manuals for the ashp but can't see the pipe size.

Also the plan is to use a DAIKIN EDLQ05CV3 5KW SMALL MONOBLOC

I haven't really looked into the ASHP yet so sorry if none of this makes sense but... so I should fit a 28mm hep2o pipe from the incoming 25mm MDPE to the ASHP, and then from there to the manifold and to the tank? I'm not going to do the actual plumbing for the ASHP or manifold but I will put the long pipe runs in place. The runs will be between 4-8m between tank and ASHP, and cold mains and ASHP I am not really sure what the mains pressure is like, I will check it from the outside tap we've got fitted... although that is reduced down to 15mm so not sure how that affects it. What is a good flow rate anyway? I will try to measure it tomorrow.

I'm sorry because I know this has been asked in various forms before but it's difficult to apply the answers if your situation is a bit different to the original question! So I'll try to be quick We've got incoming 25mm MDPE from 80m distance down to the mains. We're going to be using a Telford Heat Pump cylinder pre heated by the ASHP ASHP will heat UFH directly Pretty small house I'm about to start running the general bits of the plumbing, leaving the tank and the ASHP and UFH manifold for a plumber. Should I use 15mm everywhere, or have the main backbone of the plumbing in 22mm and tee off in 10mm or 15mm for everything except the shower and bath? Thanks!

We've just installed a concealed cistern Grohe with a RAK toilet. The cistern is one with an air tube connected to the flush plate. We've not yet connected the air tube to the flush plate as we just got to the stage of filling the cistern. When we first installed there was a lot of water constantly running into the toilet, but a bit of a wiggle of the air tube reduced this to the point you almost don't notice, but because we were looking, we know there's still a silent trail of water trickling into the toilet, and every 10 minutes or so the cistern drops enough in level to pull water through the pipes to fill it a little. We've tried some more wiggling of the air tube, I don't know if it could have perhaps gotten water or dust in it... or if there is a fault with this or something else in there. any ideas of what we should do? Let me know if you want photos of the internals. It was basically this cistern but from somewhere else as it was £140 for the cistern and frame and flush plate. pan from somewhere else https://www.victorianplumbing.co.uk/grohe-rapid-sl-euro-rimless-complete-wc-5-in-1-pack?campaign=googlebase&gclid=Cj0KCQjwzN71BRCOARIsAF8pjfgX87buV5pzucp2yASIyGfvBsCtIj1LPVYJZNj90yT2FctClptIRHsaAohNEALw_wcB&gclsrc=aw.ds
