Heat exchangers for hot tubs and spas

A heat exchanger is a device used in spas and hot tubs to transfer heat from one source to another.

Here’s how a heat exchanger works in a spa or hot tub:

  • Hot water from an existing source, such as a domestic boiler is pumped through the heat exchanger via a primary circuit.
  • The cooler water from the hot tub or spa is circulated through a secondary circuit, located within the primary circuit. (Both water systems are completely separate).
  • As the hot water flows through the primary circuit of the heat exchanger, it transfers its heat to the secondary circuit allowing the water to warm to the desired temperature and return to the spa or hot tub.
  • Tubes are typically made of a material that conducts heat well, such as copper or stainless steel. However, for hot tubs and spas using sea or salt chlorinated water (via the secondary circuit), titanium has proven to be a corrosion free material that extends the life of the heat exchanger.

Overall, heat exchangers for hot tubs are an important component of any spa or hot tub heating system, as it helps to transfer existing heat from one source to another, allowing for comfortable, year round use and energy-efficient operation.

Top-of-the-range spa heat exchangers

Spa heat exchangers are a great option for many homes and commercial properties and provides an effective and affordable way to heat your spa water. At Elecro Engineering, we manufacture three models of tubular heat exchangers with multiple power options ranging from 30-kW to 122-kW. With hot water taken from your boiler, this heat is transferred through the use of plates and tubes to your spa water. Heat exchangers are most effective for applications where the heat source is close to the spa as these need to be plumbed into your existing heating system.
