Centralized hot air heating and condensing boiler and water heater

The building is divided into two main areas: the perimeter and a central, open plan area. A cen-tralized H-shaped system ventilates warm air.Warm air heating provides comfort for the entire central area and a hot water loop heats the perimeter. In the H-shaped system, a condensing boiler provides warmth via coils.

A second condensing boiler heats the perimeter, while the H system ventilation system gath-ers fresh outside air, returned air and warm or cooled air into a single distribution point.

Home hot water is centrally produced by a condensing water heater or a hot water loop. There’s a growing demand for safer entryways in winter (indoor parking ramp, sidewalks) and a condensing boiler combined with heated concrete slabs can do the job.
