Combi Boiler and Manifold CH System
Hi All.
Per the title, this is the only CH system I’m familiar with*; and it’s the one I’d like to have my understanding checked on if the experts will indulge me… Thanks.
* are there better ways, or is this the norm?
PS, single zone for simplicity.
Edited to add, this is only about pipework layout, not commissioning or balancing. Thanks.

- Boiler has a ‘fat’ pipe taking hot water out; and a similar pipe fetching the now cooler water back to the boiler for re heating?
- The ‘hot’ pipe terminates in a convenient spot (mine on the landing under the floor), and has a manifold on it with enough ports for the number of rads?
- Similar, with the return fat pipe, also a manifold with the same number of poerts as the hot pipe?
- The manifold might have (will have) thinner pipes?
- A pipe, say 10mm, will go from each hot manifold port to the TRV side of each rad.
- The same dia pipe will go from the lockshield side of the rad back to a port on the cold manifold?
