It's all about efficiency with the dual fuel system

Having worked as a building manager for a couple of buildings, I had a wealth of experience in determining the most efficient HVAC unit for an entire apartment block.

Several tenants had been complaining of disturbed indoor comfort whenever there were power outages.

These power outages lasted for days sometimes and this meant the tenants would stay without freezing during winter or sweating themselves dry during the summer months. The tenants understood that the power outages were beyond our control but it was also their right to receive adequate heating services. I consulted a local contractor on the best HVAC unit for such a situation to which he suggested the dual fuel system. This unit worked by using two fuels, commonly an electric furnace and a gas furnace. Tenants could switch between the fuels. At a subsidized rate, the company also installed fireplaces in the apartments. These had to be gas fireplaces since there was an available gas pipe running through the building. Another advantage of this unit was that it did not need any vents, it was a ductless heat pump. This eliminated the hustle of having vents snaking through the building. The heat pump install was fairly affordable and the central heating was placed in the backyard of the complex. For quality heating, the heating technician partitioned the entire complex into zone control regions. This ensured that each apartment, regardless of where it was situated, enjoyed moderate temperatures. I circulated pamphlets that listed several energy saving tips to each tenant. A month down the line, the tenants’ feedback was very positive. Though the power outages continued all throughout the winter, all the tenant’s indoor comfort was not affected. This resulted in many positive reviews on our apartment complex.
