Plate heat exchanger - Vaillant 64kw

- Hi, and thank you for watching. In this video we remove an old Ideal concord cast iron heat only boiler on a large property and replace it with a Vaillant Ecotec Plus 64kw System boiler.
We use a plate to plate heat exchanger to separate the boiler from the old central heating open vented system and show you how we go about installing it all. Enjoy!

Very nice install. Love it,. And you and bailey as usual smashed it. Great work guys.
Thank you 👍👍
Lovely install!
Thank you very much .
Nice looking job Luke
Thank you very much Bryan. 👍
That is a sweet install mate, I've just priced something similar for a customer, I'm always nervous about pressurising old systems
Thanks Tom. Hope you are well. It definitely takes a bit of the fear out of the job, leaving it open vented. The plate worked great.
Loving this plumbing video
Thank you very much. I shall watch your videos 👍🏻
What's the score with wiring the extra pump after the plate is it just wired on the same switch live that kicks boiler and pump on
Nice work lads 👌 we’ve just done a very very similar job to that one 😎
Nice one, thank you. I look forward to seeing your installation. Hopefully, your old boiler wasn't as heavy !
Something to think about - I always thought a plate heat exchanger should be piped countercurrent
Eg boiler flow top / boiler return bottom - system flow top system return bottom
Just think of a combi plate heat exchanger - mcw and boiler return are together as are hot out and boiler flow
If you leave it like that the flow to the system will be at the boiler return temperature ie 20 deg lower then you require - plus the temperature degradation loss
To quote Andrew Millward - hope that helps 😂
I'm pretty sure it is piped that way. So each side is opposite. But the flow enters the bottom from the boiler. System flow leaves from the top. I don't believe it makes a huge difference which way round it is installed but could be wrong. Thanks
Didn’t watch till the end before making a comment 😮😂
Can remember a heat geek video on a commercial plant room in a school where they couldn’t get the rads to temperature and the plate was piped like yours
Keep up the content good to see the experiences of others in the trade 👍
@markcostello2734 Haa thanks. You had me panicking then. It was all working lovely. Thanks for watching.
@@markcostello2734 Although the system seems to be working fine and reading the right temperatures I think you are right! Someone else just commented at mentioned it. I cant seem to see the comment/person now! So if that was you thank you very much. I have the flow and return opposite which I thought was correct, but its not piped up Counter current! Thanks for pointing this out guys. I will be heading back !
Interesting job - how are they producing DHW?
They have a separate direct unvented cylinder . Strange layout . Thanks
So if the vent and cold feed come all the way down to the cupboard….why use a plate?
To separate the potential problems, the old original system could cause a modern boiler. Too risky pressurising the existing system. So playing it safe really.
@@loving-plumbing I’d never pressurise an old system either…. But an open vented boiler may have been ok in this scenario….pump so low down….no pumping over issues..and the fact the old boiler lasted so long…testimant to quite a good clean system. But I get your point
Why is the pump on the return pipe ?
It's not. It's on the flow 👍🏻👍🏻
@@loving-plumbing So, if the flow from the boiler goes to the bottom of the plate heat exchanger, when it exits, it exits from the top? If yes, why?
I’m just an apprentice 👍
@@magicalsounds7966 so it's opposite to each other. Flow in the bottom from the boiler so it heats up the return as it comes through on the other side. The two systems never actually mix. Only transfer heat.
