Combi for long pipe runs?

Gasper

I'm thinking of putting combi's in an apartment building common mechanical room (seperate boilers for each unit).  Not sure if some aprts. that are further away, will get domestic water in a timely manner?  Would a recirc. pump make sense?  Or just go with storage tanks .....or even storage tanks in the aprts. with a pump?  Thanks

can you use this boiler and put it in the apartments that are far from the mechanical room? Triangle Tube Challenger Combi heat and domestic hot water all in one small wall hung unit.
