The Sunrise Assisted Living Project hinged on a very important quality – reliability. They wanted to ensure that their heating would continue to work in the event of a loss of power. Even though a back-up generator was brought in, the HVAC system’s reliability was still a major component. The BULLDOG™ Heat Pump was indeed able to provide a system that was innovative and reliable. The advantage of the BULLDOG™ Heat Pump System is that the unit functions as a heat recovery air conditioner. It was selected to provide year round heating and air conditioning utilizing a 2-pipe heat recovery loop with an auxiliary boiler and cooling tower. The installation cost is similar to a water source heat pump system, but the energy cost will be reduced by 35 – 40% annually. Because the compressor operates only during cooling, less stress is put on the overall system and it becomes more reliable and efficient.
