Have used acova for years and they are great - now owned by Zehender and the range is very good.

How ..?? Softened water and inhibitor will protect from any galvanic reaction - otherwise any boiler fitted with an aluminium heat exchanger would fail very quickly (and there are many from the 1990’s still running)

good luck..! You would struggle to do that in blockwork for £40K with posi joists and 200mm cavity to get you to 0.15 so £20k premium for speed of installation of TF isn’t that bad. You may be pushing it with MBC - that is 6 months away and they will already have an order book for next year so I would make a decision quickly if you want a frame sometime in summer 2021.

Nope they are copies - some even have the name “Matika” on them in the same font ..

3ft long 25mm cheap SDS drill with a piece of conduit over it.

This is a waste or overflow filler. https://www.ergonomicdesigns.co.uk/product/EDRCF~round-slimline-chrome-bath-filler-click-push-button-waste-with-overflow.html The Mode Harrison can do what you want - but using a bath overflow filler - for a 1/3rd of the price you’ve seen https://victoriaplum.com/product/mode-harrison-thermostatic-bath-filler-set

They have put too much sealant in the join if that is the Hydrolock Multipanel. It literally needs a 2mm bead on the outside of the groove and the rest of the join should be dry. Did they properly remove any sealant from the one they tried previously ..?

On the form you have to tick if you own the property. The form will be available online, if it doesn’t have that box ticked then LPA haven’t followed the correct process so any application must be resubmitted.

150mm rockwool in a 140mm frame would fit as it is in compressed bales when it is sent to site but you would find your Frametherm (Not DriTherm as that is for masonry cavities) 37 would probably be closer to 0.385 due to the compression of the product reducing the air space. Either way it will be suitable and full fill means it is easier to install and not worry about it moving in a partial fill.

Errr ... that’s not right ..!!! Have you found where the water is coming in as the membrane should stop that, and then it should go over the fascia. Even if the walls get wet it should have no way to cross the cavity ..??

How about using a diverter shower and instead of the wall tap use a waste filler .? All you need is a thermostatic diverter shower unit and the rest can be done with whatever you want.

But to do that you need another pump as the LLH would be doing nothing ... So it’s now a buffer with coil, pump and a LLH... that’s added another £300... Think you are getting mixed up with the ASHP >> Manifold that relies on the ASHP setting the flow temperature and the flow rates, and the introduction of a buffer that allows the ASHP to heat a decent store of water and the flow is ASHP >> Buffer >> Manifold and the Manifold can pull as much or little hot water as it wants or needs. Simplify this and take the coil out ... ASHP into one side of a 100 litre buffer, two manifolds, two blenders and two UFH circulation pumps hooked up to the other side of the buffer, tank stat on the buffer controlling the on / off of the ASHP.. job done !

Got a link to the document this is in as it sounds like the rubbish Daikin use with their “Human Comfort Interface” which is really their thermostat ..!!

Give yourself at least 2-300mm of blue to work with off that Toby just in case you have to cut and redo the joint.

As @Conor said just make all your prep up and then cut that MDPE with a pair of pipe shears, put the insert into the tail then put your connection onto it. Don’t muck about trying to amend what is on the Toby.

Ask for the heat loss calculations that support their quotes. What is your total ground and first floor areas and have you got MVHR..??

Need to see the heat loss calculations - what are the uValues for walls roof and floor ..?? 14kW is a big ASHP - I would I be expecting half that in a decently insulated and air tight building.

The 6kW hydro box is just a cylinder in a nice package - they do the 12kW unit without it, and it’s a lot cheaper. Make sure they have priced the monoblock unit too as the split ones need an F-Gas installer and also can be a bit noisier inside the house. The Ecodan quoted is usually used on standard builds / retrofits so who has done the heat loss calculations ..? Also doesn’t make sense that you’ve got the HT unit quoted and UFH - they are again normally a replacement for standard radiator based installs and the “HT” on the Daikin is also a fairly poor CoP at high temperatures as it uses R32 refrigerant and also I believe uses an in unit electric boost to get to the top temperature. Is this a retrofit or a new build ..?

Everything after the meter / isolator is yours so yes you can. Make sure you dig around and under the join and clean it all off before you try undoing any connections though as you will have a steel pipe full of water trying to drain back into the hole ..!

+1 to this but try and get the Trade tins as they are cheaper. B&Q used to do a 5 litre for less than £50 which is cheaper than any of the others.

Also available for about £10 if you scroll down ... UK seller too .!! I thought Wish was a reseller portal anyway and not the actual retailer ..?? so what you have seen may actually be on Banggood / Aliexpress etc.

It is a private estate still and Google cars cannot enter private roads.

Looks like 1” iron but you won’t get a decent connection to that. I would go back to the boundary and excavate that Toby and you’ll find an MDPE connector on it most likely. That would be my starting point for any connection. Crossed with @joe90..!

I know where that is and used to drive past it - it’s got to be one of the most hideous buildings ever built ..! Looks so much better now but tbh that “quality” of construction was pretty standard and I’m less than surprised that they had issues. Overall result was nice and I think possibly better than the first scheme - although anyone who expected the initial one to come in at £80k was probably dreaming ...
