The TWPH-6550EHC08 is the smaller of two Deluxe models in Raypak's Crosswind V series - a vertical-discharge pool heat pump rated at 115,000 BTU/hr that both heats and actively cools your pool or spa. It runs on 208/230V single-phase power, uses a 5-turn titanium heat exchanger, and includes built-in WiFi with the Raymote app. At a COP of 6.0, it delivers 6.0 units of heat for every unit of electricity consumed. The Deluxe series adds two features the Standard models don't have: active cooling via a reversing valve, and external bypass valving that automatically compensates for hydraulic changes to protect the heat exchanger and maximize efficiency. Well matched for pools up to around 25,000 gallons in warm climates.

TWPH-6550EHC08 - Heat, Cool, and Cold Plunge in One Unit

The TWPH-6550EHC08 operates in three modes selectable from the Raymote app or the unit's control panel. In Auto mode, the unit heats or cools automatically to hold your set temperature. In Chill mode, it actively removes heat from the water - capable of dropping pool temperature 10 to 15 degrees in 24 hours during hot summer months. In Plunge mode, it can cool down to 44 degrees F, making it compatible with cold plunge setups for pools or spas in the 500 to 1,000 gallon range. For pool owners in Florida, Texas, Arizona, and similar markets where summer water temperature routinely climbs past comfortable swimming range, this replaces both a pool heater and a separate chiller with one unit.

External Bypass Valving - Deluxe Exclusive

The TWPH-6550EHC08 includes external bypass valving not found on the Crosswind V Standard models. This system automatically adjusts to normal day-to-day changes in pool hydraulics - flow rate variations from variable speed pumps, valve position changes, filter pressure buildup - compensating in real time to maintain optimal flow through the heat exchanger. The practical benefit is more consistent heat transfer efficiency and less mechanical stress on the heat exchanger over time, which contributes to a longer service life.

TWPH-6550EHC08 Raymote WiFi, VS Pump Control, and Heat Source Delegation

Like all Crosswind V models, the TWPH-6550EHC08 includes built-in WiFi and Raymote app connectivity out of the box. The unit drives most major variable speed pump brands directly without additional controllers, and includes connections for two actuators and three auxiliary devices. Heat source delegation allows it to coordinate with a secondary gas or electric heater - automatically selecting the most efficient source based on current ambient conditions.

TWPH-6550EHC08 vs TWPH-6550EHT08 - Deluxe vs Standard

The TWPH-6550EHC08 Deluxe and the TWPH-6550EHT08 Standard share the same 5-turn titanium heat exchanger, 9.38 HP scroll compressor, 268 lb weight, and electrical requirements. The differences are meaningful: the Deluxe adds active cooling via a reversing valve, external bypass valving, and cold plunge capability. The Standard is heating only but costs less upfront. If you are in a warm climate and will realistically use the cooling function, the Deluxe is worth the premium. If you only need heating, the Standard is the right choice.

TWPH-6550EHC08 - Pool Size and Climate Fit

At 115,000 BTU/hr, the TWPH-6550EHC08 is well matched for pools up to around 25,000 gallons in warm climates. In cooler climates, a more realistic estimate is 18,000 to 20,000 gallons. For larger pools needing heat and cool capability, the TWPH-8550EHC08 at 137K BTU is the larger Deluxe option. For pools that only need heating, see the full Crosswind V Standard lineup.

Frequently Asked Questions - Raypak TWPH-6550EHC08

What size pool can the TWPH-6550EHC08 heat or cool?

At 115,000 BTU/hr, this unit is well matched for pools up to around 25,000 gallons in warm climates for both heating and cooling. In cooler climates, size it for pools up to around 18,000 to 20,000 gallons. Not sure whether this model or the larger TWPH-8550EHC08 is right for your pool? Contact us before you buy and we will help you size it correctly.

How much can this unit cool my pool?

In Chill mode, the TWPH-6550EHC08 can lower pool water temperature by 10 to 15 degrees F within 24 hours under typical summer conditions. In Plunge mode, the unit can reach down to 44 degrees F, which is suitable for cold plunge use on smaller volumes in the 500 to 1,000 gallon range. Cooling speed depends on pool volume, ambient air temperature, and whether a pool cover is used.

What is the difference between the Deluxe and Standard Crosswind V models?

The Deluxe adds two things the Standard models don't have: active cooling via a reversing valve, and external bypass valving that automatically adjusts to hydraulic changes to protect efficiency and heat exchanger life. If you only need heating, the Standard is the lower-cost option. The Deluxe is worth the premium when cooling is a genuine need - typically for pool owners in warm climates who swim through summer.

What electrical service does the TWPH-6550EHC08 require?

The unit runs on 208/230V single-phase, 60 Hz power. Minimum circuit ampacity is 60 amps; recommended breaker size is 70 amps. A licensed electrician should handle the electrical connection and confirm your panel can support the required circuit before installation.

Can this unit heat a spa or be used for cold plunge?

Yes to both. The TWPH-6550EHC08 is rated for pool and spa use. In Plunge mode it cools down to 44 degrees F, making it compatible with cold plunge setups. For a dedicated cold plunge at 500 to 1,000 gallons the cooling speed is fast; for a full-size pool the same mode will take longer to reach target temperature depending on volume.
