Heat Exchanger

Heating with Aux Heating Source

Northern Lights Cedar Tubs have a unique heating system that can integrate with any other home/commercial heating system such as:

• wood fired boiler
• gas boiler
• electric boiler
• solar hot water heater

By using a combination of an external heat exchanger and electronically controlled diverter valve with the Balboa digital spa pack, you can now use any external heat source of your choice.   Efficient boiler systems and solar heating are some of the most popular choices.  Our engineers have created a universal heat exchange heating system that works by controlling the flow of heat transfer fluid (usually a glycol based mixture) through a heat exchanger when heat demand of the hot tub is needed.   Once the hot tub reaches the programed operating temperature, the diverter valve is then closed until demand is needed again.

This system can be added to any of our hot tub including our Ofuro soaking tubs.  The system can be installed as a retrofit or a new installation.
