System design question.

[Vko2]

Hi All,
My name is Mariusz. Im new to the forum and I can see already that I found a place for me. I'm working on a project bigger than I ever had and I'm planning my boiler room.

I have 3 storage house where first and second floor has 108m2 and loft around 60m2, where all will be UFH where manifolds have own pumps. I do also have there 7 bathrooms.
System also requires 7 towel rads and about 5 other rads.

I'm planning to install 2 Vaillant 630 system boilers and two 300 leters cylinders as well as low loss header where I was advice by Vaillant that WH40 is right for my two boilers.

Im looking for some information where I can taught myself and be able to calculate certain bits but it looks very complicated.
For example to size low loss header I would need to flow volume which I don't know how to figure out. I also would like to calculate my secondary pump where I think I'll need one.

Thanks for any advice

If you don't know then pay somebody to provide the info. Knowledge has a cost.

I may have to but I do like to understand things myself. I'm not asking for ready info but for resources I could start to teach myself.
Thanks

7 bathrooms and only 5 other rads ??????????

Give me 5 or 6 years and I'll teach you most of the stuff I know.

I can see you having fun but you have to start somewhere

Fun my arse.

You're not going to pick up what you need in a few hours of looking at a book or on the internet.

Time to employ a consultant or design engineer and work with them.

Must admit I was thinking guest house.

Poland sounds like it mariusz is typically polish writing

I’m sure if you’re using vaillant boilers etc... the rep may design the system and they’ll probably charge you.
