Hot Tub Heat Pump

Arctic Heat Pump – North Americas only UL listed cold weather spa heat pump.

Heat pump technology has been widely adopted in the pool industry due to its significant cost savings. In fact most pool heat pumps can save owners 70% or more in heating costs. However these heat pumps have two major problems.

  1. They only work during the pool swimming season and quickly lose their efficiency as the outdoor temperature drops.
  2. Their achievable output is the upper 80 degrees, much too cold for hot tub temperature.

Until now most spa owners were stuck with standard electric heaters however electricity is becoming more and more expensive and will continue the upper trend. Northern Lights has partnered with Arctic Heat Pumps to be the exclusive OEM hot tub supplier to use this technology. The Arctic heat pump produces between 14 Kw (high temperature rating) and 4.5 Kw (low temperature rating) of heat energy and can safely do so in temperatures as low 20 F (-7 C) while still providing homeowners operating cost savings over regular spa heaters. For those in climates exceeding this we offer the Hybrid Heat pump system that includes a backup 4 Kw Balboa Spa Pack that will automatically provide extra heating power when needed.
