I was wondering if any of you can assist me with some considerations and tips on designing a ring mains for a three storey building..We plan to do it all in copper…
The Storage Unit and Heat Pump water heater will be at basement level..
Then we will have
1) 4 apartments (4ppl per unit) on the 1st floor 2) 8 apartments (2ppl per unit) on the 2nd floor 3) 10 apartments (2ppl per unit) on the 3rd floor
I usually only work on domestic installations, but I am clueless on these bigger designs…
Info that I require..
1-) Piping diameters upwards to each floor 2-) Piping diameters branching off to each floor 3-) Piping diameters branching off into each apartment. 4-) Pump(flow rate) required to handle this 5-) How will it be controlled, as we do not want the ring mains pump to circulate throughout the day. it is residential and we will only need circulation around 16:00 to 08:00..
