Inefficient Terminal Reheat Systems or VAV Systems

By · January 16, 2011 · Filed in Energy Efficiency, Green Solutions · Comments Off

Many buildings built during the boom of the seventy's and earlier have terminal reheat systems or VAV systems with a hot water radiant loop on the perimeter. These systems as originally designed gave no consideration to energy consumption or the environment. An analogy of how these systems operate is that like driving your car with your foot on the gas full throttle and putting your foot on the brakes to slow down.

Change Dirty Air Filters

By · January 16, 2011 · Filed in Energy Efficiency, Green Solutions, Indoor Air Quality · Comments Off

Most modern heating equipment is designed for a maximum temperature increase of 25ºC to 45ºC,  while it is actively heating. If your air filters become dirty and reduce air flow, the efficiency of the unit substantially is reduced and relies on the high limit to cycle the burner off.  This reduces the life of the heat exchanger and leads to high limit failure.
