What would you do...

What my mate had done was build an external boiler house nothing special but at the rear of the house just upvc feather edge and timber some doors and a bit of kingspan.

2 system boilers zone per room, and 1 for the communal. 2 santon premier plus cylinders in the boiler room with secondary circulation. Then shower room in each room. It's mainly let to northerners down working the week on the power stations but it's always let

Cwsc boosted cold and three logic 30s hooked up to two ACV sle plus 300's and zoned rads and a communal zone. But u need to insulate lots

Why not fit a underfloor heating manifold, one zone per room, with stat in each room?

Not dynamic enough, that would be my worry.

I have been to few jobs , where land lord had exactly the same lay out . Up to 10 rooms and few bathrooms !
They all had a 300L unvented with large size system boiler and boiler set to heat water 1h before rush hour of showering in the morning and run up to 8am ! Then evening from 5/10pm .
they never had a complain to never had enough water !
If you do this just fit twin coil UHWC and run primary to cylinder in 28mm also , hot water distribution in 28mm

Thank you all some really interesting thoughts there

For UHWC make sure there is 32mdpe and 2/3bar working pressure at test point when you have 1 other tap open and you will be ok
