Help! Nest - Dual zone - Opentherm!

Not yet.. That's on the new system which will be fitted at the start of next year. I've a few jobs to do yet... Including sorting the electrics, clearing space and shifting things for the new cylinder etc...

This is the original 1986 boiler and open vented cylinder. Not doing bad considering

Yeah that probably won't modulate, but you should be able to adjust the flow temperature manually.

You can with a dial.... It's set at max, pump on lowest and set to cycle 6 times an hour on the communicator... Any thoughts on best settings?

I apologise for being late responding on the thread. However Drayton have released a good system this week. Just mentioning it as it gives other people reading the thread another option to look at. Should they wish.

Slightly old thread resurrection!

I wanted to come back to you all and say thank you for all the guidance on this project. It was finally completed in July - I am absolutely blown away with the results. Definitely worth all the hassle - huge shout out to my heating engineer who took the Atag course especially for my requirements due to the Viessman not working properly with Opentherm.

Thanks for coming back

Everything looks great except my opinion few snagging points

D1 is too long
D2 is too shot
(Unvented safety vent d1 is the distance to the tundish 600 mm max, d2 is from the tundish to the first bend 300mm min)

Condense doesn't look likes it's falling might be the pics

Are the pipes now insulated?

Thanks Shaun!

There is a very slight drop on the condense... The other areas, D1 and D2, are you saying the tundish should have been mounted further up?

Is this the end of the world type deal where i need to get him back?

I might have impacted this as needed this area to be compact, as a fridge lives next to this area, pushed up (but not touching).

Thanks

Tim

Correct and if it every discharges it could overflow due to the bend being too close, I'm very surprised he's done it as it's regulations

D2 is the most important one

Hope you don't mind

Not at all Shaun, I'm glad you mentioned.

I'll get him back to rectify....
