Pool / Spa Heating
APOLLO Pool and Spa Heat Exchanger
Heats pool or spa water by exchanging heat with a separate heat source loop — such as a boiler or heat pump circuit — rather than heating the pool water directly, which keeps the pool's water chemistry isolated from the heating equipment's own loop.

Answers
Frequently asked questions
How does the APOLLO Pool and Spa Heat Exchanger work?
It transfers heat from a separate heat-source loop into pool or spa water. The source loop can use a boiler or heat pump, while the pool water remains in its own circuit rather than passing directly through the heating equipment.
Can it be used with a boiler or heat pump?
Yes. The APOLLO Pool and Spa Heat Exchanger is designed to receive heat from a separate boiler or heat-pump circuit and transfer it into the pool or spa loop. The source equipment and exchanger must be sized together for the application.
What capacity options are available?
The available capacity tiers are 55, 155, 300, 600, 1,200, and 2,400 KBTU. Select the tier based on the required heat-transfer duty, pool or spa system, and operating conditions.
Should I choose Stainless 316L or Titanium?
Stainless 316L is intended for chlorinated pools. Titanium is intended for saltwater pools, saltwater spas, and other more aggressive water chemistry. Match the material to the actual water-treatment conditions rather than treating the options as interchangeable.
What connection sizes are available?
Connection size scales with capacity, from 3/4- to 1-inch connections at the 55K tier up to 3- to 4-inch connections at the 2,400K tier. Confirm the required connections against the pool and source-loop piping.
What is the inlet and outlet configuration?
The Pool and Spa Heat Exchanger uses same-side inlet and outlet ports. This configuration can simplify piping compared with designs that place the connections on opposite sides of the exchanger.
How do I size a pool and spa heat exchanger?
Choose a capacity tier based on the required heat-transfer duty, then match the material to the pool or spa water chemistry and confirm flow, pressure, and connection requirements. The Pool Heat Pump Calculator sizes the heat pump itself, not the heat exchanger.
