Ideally by phone and Amazon echo... Which I know is the main complication here. Just trying to automate
 
Then you would need something like as you say hive/nest etc
 
I originally looked at hive.. it looks really good. I just think the nest is slightly more pleasing on the eye and more scalable with Google.... Nice tends to play to its own products from what I've seen.

What's your thoughts on them?
 
TBH it's what fits your needs and eco system

There all about the same, some will work with different software some won't
 
Without wanting to start a further thread...

Do you gents happen to know much about hot water loops? In regards to hot water reaching its destination faster and so using less water, wasting less of the cold in the loop that you'd ordinarily use in a normal hot water branch off.

I've done a bit of reading and can see that some countries use this a lot, especially where they suffer droughts. I'm obviously thinking of the hot water wait time, but like the idea of water save too.

As I'm fitting this new water main in the house, terminating at the new boiler site. I'm wondering if I should tap into the downstairs hot water to create a ring - I've already ran a new feed for upstairs - when that gets plumbed into the new boiler, we'll have the option to create a ring.

The reason I ask this is because I have read about some rings that feed the surplus cold water back into the tank for reheating which sounds a bit more complicated than what I am suggesting.

Thoughts?
 
You mean a secondary return

If it's a big house with a long hot draw off run then yes you need to fit one

Water regs say anything more than 30 seconds is a waste of water and need a secondary return fitting
 
Thanks Shaun, so that in its basic form is another access point to the ring. Simple as that...

Currently the hot water tank is located on the first floor, therefore there's a simple drop to downstairs and branches to upstairs. Guessing there's no complication in how the ring is formed.

I don't think the house is that big tbf. It's a medium sized 4 bed... But seeing as I'll have access to the pipework, figure it's worth hitting
 
You need a check valve and a bronze pump

Thanks Shaun.... That diagram is for vented, do i defo need the bronze pump on boiler/accumulator or unvented set ups?

Scott, I'm using speedfit on copper.... Are you saying that's not suitable?
 
Yes both the same the only thing that isn't on there is a check valve Normally fitted between the cylinder and bronze pump

And that's fine just can't use plastic pipe

Make sure it's well insulated
 
No probs... Is it worth bothering do you think, would the hot water coming through be that noticeable in a house this size? I'm fine adding the pipework but given the cost of the pump and added complexity.

The runs are mostly in the insulated garage. I've used the thickest foam I can get away with for the 22. Going to have to source some thinner for the 15mm due to my brackets restricting.

Quite involving this plumbing lark! Been at it all day trying to do as much as possible, getting access, laying pipes etc before having to turn the mains off and drain the Ch. 600mm to get through the garage wall! Massive pita
 
That's upto you tbh

And it would of been easier on you if you had a plumber (who is gas safe and G3 registered) helping you :D
 
It definitely would. Only reason I haven't is, my trusted chap is always so busy, I'm always conscious of this so try not to trouble him unless I absolutely need to :)

Plus I enjoy it... There's a challenge around every corner! :D
 
Morning chaps - Success! I have managed to replace the cold water main, hot next followed by the CH repiping.

Question - As I will be looking at a complete new system in Jan-April time - firstly, do new boilers tend to have their own magnetic and solid filtration?

My thinking at the moment is this - to fit either a second hand Magna to the 22mm pipework to cleanse the system prior to the new one being fitted.

The dilemma is, do i spend £40 on one of the few second hand ones on ebay as a make doo (best option if new boiler comes with one) or go and buy a new 22mm Magna, or perhaps the Magna pro 2 if it's worth the extra? assuming it will get used on the new system.

Thoughts please :)
 
No they don't

Best option is both but not second hand

Adey pro 2 would be the best one
 
Thanks Shaun! much appreciated as always.

Gathering the Adey 2 is worth the extra, what's the difference? - do they lose their effectiveness with age? and whats the service/shelf life of them?
 
Yes just overall better design
 
Cheap and nasty

Either adey or spirotech
 
I was just looking for best price and stumbled upon a thread from years ago....

Seems best I can see atm is £82 - amazing how some places are wanting £120 for the same item!

This won't be fitted optimally for the moment - I can't get it near the current boiler so it will be on the ground floor pipework - current system being upstairs fed - gather any crap from upstairs will always work its way downstairs with gravity and be swallowed up in this...
 
Yea that's made by them
 
How do they work in comparison to the Magnaclean's - they don't seem to be magnet based, perhaps swirl pot style filter?

External magnet

Black shroud
 
Thanks Shaun...

Last question on this - which would you fit on your own system?

Adey pro 2
Spirotrap
Spirocombi
 
Adey pro 2

But there all about the same
 
Update... I only had one option I could go for given its first location will be beneath the floor, and the flow on the return will be coming in from the top assuming the Adey or spirocombi due to them having to be upright . So I went with the MB3 separator in the end... Spoke with Spirotech prior to ordering for confidence in the filter material and the getting the right option. I had gone to them with the idea to buy the spirocombi sludge and air remover, but the flow wasn't in the right direction for my situation and the lady kindly pointed out that it wouldn't work optimally anyway... As a proper industrial set up by comparison would have the sludge remover on the return and the air remover on the flow... so I've managed to get the MB3 and RV2 for the price of the combi model @£115.... One place had this package, the rest all wanted close to £150 for both! Job well done I think...

Don't make me cry with a decent trade cost please :D
 
Company called Viessmann Direct... Found it purely by chance. Even the eBay specials wanted £65 for the MB3's... The RV's were even more everywhere I looked
