    As @jack says I would split it over 2 days. Not a huge amount to dig but watch your levels and don’t forget that you need 50-75mm gravel under the pipe so it may need to be deeper and you do need to take levels into consideration.

    Give it a stir and see if it is still soft. If it is, use it....

    My triple was cheaper than others double and better performance ...... reset the balance ...?

    Personal experience of 3G in UPVC is noise and the lack of a “cold” feel near the glass. Very surprised how much heat they retain, downside is that you do lose a lot of the solar gain so they have a mix of benefits.

    Ability to change and modify is the issue with press fit - they also use bespoke fittings.

    AutoCad has a read only file setting but you can just save as and take it off. I do get the issue however building and design need to join the 21st century at some point and realise you can use CAD,TotalStation and 3D machining as a system.

    Ok so that’s a diverter then - all good ! What stat is on the buffer ..?
  8. PeterW
    Ok so I’d assumed it was a standard 2 channel timer, but looks like they are using it as a single to control the hot water only. These things must prioritise internally then as that’s a standard diverter valve not a mid position valve !! @joe90 was the 3 port supplied with the pump ..??
  9. PeterW
    You can’t do that with the Aeromax as it only controls the 3 port. It has no concept of zone valves and it controls the flow temps internally to the two separate circuits.

    I think from reading the manual, the UFH circ pump will need to be triggered from the room stat and the buffer stat will need to trigger the ASHP. That would mean the connection on 3/6 from the room stat would be the tank, and the programmable stat would just fire the circ pump. The downside is that it means the UFH could call for heat from a cold buffer, or wipe the buffer out pretty quickly if the ASHP is in DHW mode. You could use a zone valve with micro switch to trigger the pump too, or make it force the ASHP into HTG mode. I’m still trying to work out why the Timeswitch connects to 13 on the controller directly and via the stat as the info on the web is less than helpful !!

    From memory you also need to use stainless fish tail ties as they will fit in the joints. It does make coursing a bit of fun but works better when you use old imperial size bricks as they take up the gaps that would be mortar joints.

    We have friends who had a house designed locally and one architect gave them the terms of business and there were clauses in that related to TV programmes and that if the designs were used in a TV show there was a 10% uplift in fees to cover “artistic rework” and any interviews to camera would be something like £500 plus VAT ..! Not sure if they had a bad experience with a show, or wanted to get some money from glory ..!!

    Just fitted a DIY kitchens one and it’s pretty much perfect. Contrast the Howdens one I fitted last week for a similar value and they are chalk and cheese.

    300mm fibre in a 350mm cavity could be replaced with blown bead for an equal (or slightly better) wall performance and no need for any of the other products.

    @Olly P I suggest you have a read of the parish council minutes for previous meetings before you attend. They can be very vociferous in their approach and you probably need to understand who comments on what etc which the minutes “should” record... and use that to focus your information. Also ensure you tell them you are coming - write to the secretary and say you would like to discuss a proposal for a new family home (note the wording...) then if they decline to meet you, I would keep that and potentially use it if there is any issues. PCs are normally ignored if it’s nimbyism around rejecting PP but having them support is useful.

    Not exactly game set and match as you quote a single item as being a benefit and as @dpmiller says, to maintain reliability you need a honking big heat sink so your pretty SSR is now taking up the space for a single SSR that a 3 pole contactor would use ... ? As you blatantly ignored the logic level switching argument, the notion of using AC switching at load line level requires bridge rectification and other components within the SSR to enable the activation of the load which further adds to the MTBF reducing argument due to infrared component complexity .... Now where is the umpire ...??? @JSHarris..!!

    Crack on and do the job as you’ve started - take comfort in the fact I’ve seen professionals do worse ...

    Sonoff do one - does that help ..??
  20. PeterW
    @Nickfromwales Solid state failure (esp Chinese cr@p) will fail unseen and has no physical indication of either failure or actuation. They are also single pole and leave the neutral in place so cannot be deemed to completely isolate the circuit. Given it’s likely that these will change over at significantly low frequency, the need to use an SSR that is designed for high speed and high frequency changeover, usually driven at logic level, then the argument for using them is drastically diminished .... your turn .... ?
  21. PeterW
    Hmm ... let’s agree to disagree on that one..!
  22. PeterW
    You would melt the controller ..!! It needs a contactor in the circuit to handle the high load side of it - £15-20 on eBay or other sites. If you just want to have a play about I think a standard immersion timer would be fine.
  23. PeterW
    They are a standard 11” immersion in a threaded case - some are pretty much a 63mm copper pipe section with a brazed in end and a brazed brass immersion flange with a couple of 22mm compression fittings attached.

    It’s to do with getting a decent thermosyphon as a Willis in a tank situation uses the cold of the header tank and the rising water temperature in the feed to create the thermosyphon effect. In this instance it’s only on when the pump is on so doesn’t require the thermosyphon to work. The other factor is thermostat failure on the immersion so it could boil however most modern thermostats have a secondary non resettable fail stat at 80c.

    I think the only part affected is the garage so unlikely that HSE would wrap the whole project up with a stop notice as nothing dangerous has occurred (ie no reportable accident or near miss) so it’s unlikely the would be involved. Would also be interesting to see where the plans show the cables for the DNO and where they actually are. We have some woodland and had an extensive site survey done with GPS and found the poles for the farm power lines were 6m out and when we checked we found existence of the old line but the wayleave and DNO asset maps hadn’t been updated.
