Hi y'all,
Advice required for body spray jet flow-rates please... Alas money is not unlimited, but would rather get it right first-time around!
Incoming MCW pressure seems good. Boiler install in loft of 3-bed house to feed kitchen sink, downstairs WC basin, utility room sink and two bathrooms:
- Family - Basin, bath and separate shower (including body jets - see below)
- En-suite - Basin and shower (including body jets - see below)
Shower mixer valves (3/4" inlets / 1/2" outlets) are thermostatic 3-way diverters. Both showers will have:
- Fixed overhead ceiling spray head.
- Hand-held spray head.
- Body jets - which is proving difficult to specify boiler type:
... at 0.5 bar = 4.1 l/min flow rate.
... at 1.0 bar = 5.2 l/min flow rate.
Therefore:
- Best case (if only fit 4 x body jets) at 0.5 bar requires 16.4 l/min flow rate.
- Worst case (if fit all 6 x body jets) at 1.0 bar requires 31.2 l/min flow rate.
Will probably be rare that both showers would be used at the same time.
SO THE BIG QUESTION - system boiler and unvented cylinder, or highflow combi to provide the desired showering experience?!
Many thanks in advance...
