Hi Andrew, I have this design guide and have a question, not sure if its worth a video but how is circuit flow rate calculated? The design guides calculation doesn't seem accurate?
What would you do if there will be system boiler with cylinder and hestmiser controllers in place to control very large ufh and radiators? There is not much really you can do there. Everything would need to run on 70 degrees right?
You can fit WC on any underfloor system to get better comfort. Efficiency from the boiler will be improved with WC also even if set for the radiator circuit.
1.Whats the maximum a floor temperature should be before it becomes uncomfortable to walk on (I thought 27c was max) and are them MWT shown for when it's -3C outdoors? For a 20c indoor design temperature, the 40 MWT example shows at 100 centres that the floor will be 25.8C. 2. I'm presuming to obtain the tight radius using 100mm centres, it needs to be laid in the snail pattern not serpentine, is this possible for narrow rooms like a hallway or utility room?
Like the old saying goes........"Its better to be looking at it, than for it".

Mass flow rate. Dt and power required. Dt7 is normal for ufh.

Floor temperature and mwt are not the same. I think 27 or 29 from memory if in traffic area.
