Cost to separate utilities, install boiler/hot water tank

[Keith Ellis]

I'm doing some analysis on a 2 flat which currently has one gas and electric line coming into the building and a single boiler and hot water tank. Can someone ballpark (a) the cost to separate the lines so each unit can get their own bill, and (b) the cost to install a boiler and hot water tank (or tankless) for a unit roughly 1500-2000 sq ft?

Thanks!
