A Boiler and Indirect Storage Tank Setup with Primary Loop

This is how you can set up a Gas Boiler with an indirect storage tank. This gives you alot of Domestic Hot Water along with a Closed Heating Loop Zone for one Temperature Systems - Radiant or Radiators.  If you reqiure multiple tempeature system, then you set boiler at top temperature and then use mixing valves to reduce the heating legs that require lower temperature water.

Boiler with Primary Loop and Indirect Tank Setup

This is only an example. Actual layouts vary from job to job.
