Low Loss header , remote from boiler

Gez2312 · Feb 1, 2019

Just about to start a job , system boiler , ufh zone , cyl zone , rad zone. It’s quite a big house so was going to add low loss and pump to aid , but it’s tight for space where boiler is going. Ufh manifold is going about 10m away in a cupboard , where I’d have loads of room for my zone valves , low loss and pumps. Could anyone see an issue with doing that ? 28mm from boiler to low loss 10m away ? I’ve fit them before but always put close to boiler. At a squeeze I could fit low loss with boiler and then pump to zone valves 10m away if that makes sense ? Any advice gratefully received, many thanks

As long as the pump on the boiler is enough to pump the circuit to the header then, no there is no problem. I have done similar before. On one commercial job I used a plate at the boiler end and a LLH at the other due to distance - with an additional pump in between - you won't need that but your idea is good, go for it.
