No! I need the VRG330 pattern… In the video they explain the flow can either come from the square or the triangle but not the circle. This is exactly what I need! The reason for the video was to share information with future readers of the tread…

I am not sure the mixer part is required with the ASHP installation but it looks like the right solution. I can see Daikin ASHP use the same valve.

Yes! I think it can be combined with a ara600 to create a 3 way diverter valve for a high flow installation! https://esbe.eu/group/products/rotary-actuators/ara600-2-point Exactly what I am looking for! Thanks for all the assistance and comments!

Could this not be a potential solution??? Or have I miss understood something? https://esbe.eu/group/products/rotary-valves/vrg330 Anyone have any experience with ESBE controls???

@CBW I just looked a little closer at the link you provided and can see that it is a manufacturer website. At first glance it looked just like a blog about different types of valves. @JonathanM Yes the is correct it is a 90 degree T-port flow pattern D valve. I couldn’t see from the link that...

Not really it doesn’t say who makes them or where I can buy such a valve, but thanks!

Yes a 3 way diverter would work fine… But can I get one with the flow described for the bottom image. Most 3 way diverters the flow comes in to inlet C (A/B). That doesn’t work in my case I need to have the Flow (A/B) coming into inlet A preferably with as large a bore as possible to maximise...

Hi Everyone, I have a question with regards to a specific requirement I have for an electric 3 way diverter 28mm valve on an ASHP installation? As far as I know most 3 way valves are configured so the flow comes into the bottom of the 3 way valve (Inlet: C) and then the water either flows out...

Thanks! Very helpful! I would have never have guessed to look in the plonke shop! I presume this is the correct size? https://plonke-shop.de/wellrohrverschraubungs-set-dn-25-1-1-4 Thanks again!

Have a look at this thread: https://www.diynot.com/diy/threads/shortening-a-flex-stainless-steel-pipe-for-ashp.627595/ Same issue!

yes the fitting is 28mm but if you look at the picture the pipe has been flattened. If I shorten the pipe it will be over the corrugated pipe and therefore need a circlip. My question is what size should it be over the corrugated pipe and where do I find such a fitting?

Before everyone starts a discussion about gas advice! These pipes a flex pipes for a ASHP flow and return! The are use by Vaillant for water!!! https://www.cityplumbing.co.uk/p/vaillant-arotherm-flexi-hose-750mm-20165288/p/130849?text=Vaillant%20Flex%20hoses Annual fittings are also used for...

Hi All, Can someone help me identificere What size DN pipe diameter the below stainless steel flex hose is? I dont usually work with this type of flex hose and due to the corrigation i am not sure What size annular fitting I need? Is it based on the internal bore size of the external...

I just ordered another set for a new install today and got a completely new set of flex hoses which look nothing like the original Vaillant AroTherm flex connection set.

Hi Everyone, I was wondering if anyone knows of a way to shorten a flexible stainless steel flex hose for a Vaillant ASHP? I have previously purchased flex connection hoses from Vaillant that could be shortened using a circlip, but it would appear that they have changed their manufacturing...

Thought some people might be interested in this video… Seems relavent to this tread

@MNW67 Thanks for the response! I actually found a really interesting article on the home automation site, which uses the myVaillant API. I would imagine that if this is possible then Homely potentially could do the same! https://community.home-assistant.io/t/myvaillant-integration/542610...

Hi All, I am curious to hear if anyone knows if the Vaillant VR33 Module that can be used to convert Vaillant Boilers to support OpenTherm also works together with the Vaillant AroTherm ASHP range? As far as I can understand Vaillant uses a very old protocol (eBus) for communications between...

@MNW67 Have a look at the new Newark Heat Geek Cylinder Specs... In addition to this you can also see Adam's Cylinder performance here on the Open Energy Monitor Community Forum. https://heatpumpmonitor.org/system/view?id=46

@ScottishGasMan I am planning on installing a Vaillant Aerotherm Plus 7Kw Heat Pump and have just decided to go with the Newark HG 6m2 coil cylinder. Attached is a copy of my MCS Heat Loss Calculation for anyone who is curious... Just to point out again I live in Denmark and our outside design...
