I WILL NEVER TIDY UP EVER! A messy building site is a functional building site. A tidy building site is one where no one does any work because they are too busy tidying.

I told SWMBO I'm going to build a lift. Her immediate response was "Will it be permanent?" LOVE IT!?

Now we're cooking. Any photo's of your creation? How do you bolt/connect the scaffold to the A frame part?. I will need some guidance on what to buy /how to connect it - also would like to bolt the whole structure to the concrete wall. Just had a brilliant thought! - the LIFT COULD HAVE A GLASS FLOOR!!! ?

Yeah I looked into those. It's rough ground all around but it is do-able ( ignoring cost ). A lift sounds MUCH more fun!

I really don't want stairs. My previous ones rotted away. Also it is rather awkward/dangerous when carrying loads - so I do need a 'lift' of some sort

Quick google 3k!!!

Below ground floor top of wall 2.6 m

Scaffold steel be better?. But what about most important part the gantry ? i.e the bit that's taking the load

Yeah . I thought about that - but there's no real good ground to stand it on. Bolting it to the walls seems a bit risky. A mini elevator as in my latest video seems cool - but out of timber????!!!????

Wow!

I wish

My single unit uvc turned up yesterday with installers . It weighed 130kg and worse it was top heavy . Nothing to dismantle. We tried multiple ways ( strapping it to a ladder , lower ladder etc. ) - to get it underground . It was fairly obvious this was a risky thing to do . So I quickly ( expensively ) ordered a crane to lower it down . As I’ll have loads of other large items and heavy I really need a cheaper method I can use over and over again . My temporary staircase just isn’t suitable to carry down a washing machine safely . So I look out the back - thinking what can I construct that can lower materials / items safely ? . Perhaps a crane/winch bolted to the concrete wall ? Want some thing that will take the weight of a large American fridge freezer , washing machine , plenty of materials . A nice hydraulic lifting platform would be good ? Ideals welcome !

Digest fellas !! The HP pump isn’t circulating through the UFH, it’s only circulating to the buffer. There are pumps on each of the UFH manifolds that draw the heat from the buffer when one of their respective zones call. The actuators will close and the pump stop circulating once the rooms are satisfied so I’m not sure what constant circulating or overheating they are talking about. The flow temperature from the heat pump is weather compensated at a maximum flow temperature of 35C at -1.6C external temp. down to 20C at 15C external temp. The mixers are mechanical so there is no control, they are set manually. The minimum temperature they can be set to (35C) is higher than the maximum design temperature of your system so they are practically redundant as under the design conditions the heat pump will not produce heat higher than this. If you want to add mixers you will need to add an additional pump and control on the buffer side to take the heat from the buffer to the manifolds when either of them called. Also, as the mixer wont completely close the flow temperature will need to be set higher to compensate for this mixing and increase the running costs. I do not recommend mixers on a low temperature system.

This is exactly what I was thinking .

Lol @Nickfromwales you’ll like this . My guy hasn’t replied yet . So for fun I just called 2 random online ufh / ASHP retailers whom have a technical support team . Both said blender not needed and they don’t sell a blender with their ashp systems . Their logic being the ASHP never generates water hot enough to be an issue . Now don’t shoot the messenger !! ?

To late . They’re doing everything I.e pv , uvc , ASHP So I’m obliged to the contract . Pv in . Global pandemic put a hold on things . So only just back in comms with them .

My installer doesn’t think a blending valve is needed for ufh ASHP . I’ve sent him some of the comments from here - be interesting to hear his view.

Yes . They are expensive for what they are but takes 5 mins to install

Excellent! I’ll check out the Salus ones ! ?

Think I fancy pixie Lott - just saying - bet she knows everything about ufh .

Ok . That simplifies it - blending isn’t something I fiddle with . Makes life easier ! . Though an actuator per zone and a z wave relay per actuator . It seems strange actuators are closed by default and open when powered . Basically using electric just to stay open - would of assumed they are powered open / closed and then just stay in that position not using power ( like a trv type screw thread to open and close ) .

Ok Here’s my ‘logic ‘ . To automate each zone I have an electrically operated actuator per zone . If no zones are being heated then pump is off . Do I need to automate the mixing ? - or do I not care about that I.e water into the ufh is always blended. ??

I’m confused now ! I thought no blending valve for ufh but valve for dhw and ASHP . But I’m confused ....
