Inside, the Zehnder Heat Recovery Ventilation (HRV) system works around the clock to expunge stale air and fill the home with fresh, clean air, while also maintaining a comfortable temperature year-round. Showcasing Dwell Development’s commitment to pushing the envelope of sustainable building, the team installed a 450% efficient hot water heat pump from Australia to provide hot water and in-floor radiant heat, “this system is revolutionary for the industry. The Sanden uses 1kW of energy to generate 4.5kW of heat, that’s 78% less energy compared to traditional hot water systems. Not only is it better for the environment, its better for the homeowner’s bottom line.” says Anthony Maschmedt.
