Mixed water loop and centralized combo

Solution suitable for a 50-unit or more building

A high-performance solution that lives up to expectations.

The solution

This solution is one of the most effective, innovative designs in recent years for 50-unit or more buildings. It’s effective because a centrally located condensing boiler, combined with a mixed water loop, warms each dwelling via a heat pump. A centralized condensing water heater—which maximizes the floor space of each dwelling—ensures the flow of hot water. And it’s innovative because it pairs natural gas with a heat pump to get the best of both worlds! The result lives up to expectations.

Optimal solution set-up

1- Heat pump

  • Connected to a water tower and a boiler—warms and cools air in each unit.

2- Condensing water heater

  • Reuses latent heat energy—a high-efficiency appliance.

3- Condensing boiler

  • A more compact appliance—facilitates integration into mechanical rooms.

The minimalist duct revolution

Did you know that warm air can be diffused from high up on a wall opposite a glass surface without sacrificing comfort—and in both heating and cooling mode? The minimalist heating duct design, as it is called, reduces the required length of the air ducts, creating a compact heating design.
