Mixed water loop and condensing boiler

Solution suitable for three-storey office buildings or higher

The solution

A large mixed water loop—or warm water—circulates throughout the building and warm water is fed into this network via heat pumps. To regulate the room temperature, the heat pump will either heat or cool the air and inject the desired temperature into the big loop. The water cooler or boiler maintains the water temperature at its set point for the optimal functioning of the heat pump. During the winter, the boilers do the most work; in summer, the cooler and water tower work hardest and in between seasons is the time for recovery work. North-facing areas inject cold air into the loop, which is used to cool the south-facing areas, where air condi-tioning is needed. For this system, we suggest a condensing water heater to ensure the hot water supply.

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.
