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.
