Rooftop unit, duct heater and tankless water heater

Solution suitable for a strip mall

The solution

The commercial spaces in this type of building are smaller than in commercial condos and each one has its own door. But good things come in small packages: a roof unit controlled by a single thermostat is used for two or more businesses; a duct heater makes it easier to customize heating and minimize installation costs; and a tankless water heater produces hot water eco-nomically.

Optimal solution set-up

1- Roof top unit

  • Decentralized ventilation system
  • Efficient heating of open air central zones
  • Modulating options

2- Duct heater

  • Easy and direct fitting to the ventilation system
  • Flexible (can be combined to the air conditioning and humidifier system)

3- Tankless water heater

  • Requires little space
  • Energy savings ranking from 10 to 40% annually compared to a storage water heater
  • Lifespan that can exceed 20 years
