high mass low mass

Mellow_2

With a buderus g115 with a 2107 and room sensor. What would be a good way too connect a system that has a monoflow loop with cast iron radiators..........and a baseboard zone? Both zones to the limit of output(very long). I want to put the high mass on constant circ and slave zone the bb zone. what do you think????

PS Iwill make sure it will be the right boiler to match the system and the loops are correct. Will the bb zone work the best way? Should you slave the high mass or mix it?


PSS I find this system in alot of homes.....bb seems to be an afterthought....
