Raypak Crosswind V Deluxe Pool/Spa Heat Cool Pump 137K BTU TWPH-8550EHC08 (Heat/Cool)

The TWPH-8550EHC08 is the largest model in Raypak's Crosswind V Deluxe series - a vertical-discharge pool heat pump rated at 137,000 BTU/hr that both heats and actively cools your pool or spa. It runs on 208/230V single-phase power, uses a 6-turn titanium heat exchanger with a double-row coil, and includes built-in WiFi with the Raymote app. At a COP of 5.8, it produces 5.8 units of heat for every unit of electricity consumed. Like the smaller TWPH-6550EHC08, the Deluxe adds active cooling and external bypass valving over the Standard models - plus cold plunge capability down to 44 degrees F. Well matched for pools up to around 35,000 gallons in warm climates. TWPH-8550EHC08 - Heat, Cool, and Cold Plunge at Maximum Residential Output The TWPH-8550EHC08 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 removes heat from the water and can drop pool temperature by 10 to 15 degrees F within 24 hours. In Plunge mode, it cools down to 44 degrees F - suitable for cold plunge setups in the 500 to 1,000 gallon range. At 137,000 BTU/hr it reaches and recovers temperatures faster than the 6550EHC08 in either direction, making it the better choice for larger pools or owners who want faster response in both heating and cooling. 6-Turn Double-Row Titanium Heat Exchanger The TWPH-8550EHC08 uses a 6-turn titanium heat exchanger with 16 circuits on a double-row coil - the same high-output configuration as the TWPH-8550EHT08 Standard, now with cooling capability added via a reversing valve. More circuits and a second coil row means significantly more contact area between refrigerant and pool water compared to the 5-turn single-row design in the 6550 series. Titanium construction resists corrosion from chlorine, salt water, and bromine throughout the life of the unit. External Bypass Valving - Deluxe Exclusive The TWPH-8550EHC08 includes external bypass valving not found on any Crosswind V Standard model. This system automatically compensates for day-to-day hydraulic changes - variable speed pump flow variations, valve adjustments, filter pressure changes - maintaining optimal flow through the heat exchanger without manual intervention. The result is more consistent heat transfer efficiency and less mechanical stress on internal components over time. Raymote WiFi, VS Pump Control, and Heat Source Delegation Built-in WiFi connects to the Raymote app out of the box - no gateway or separate module required. The unit drives most major variable speed pump brands directly, includes connections for two actuators and three auxiliary devices, and supports heat source delegation to coordinate with a secondary gas or electric heater automatically based on ambient conditions. TWPH-8550EHC08 vs TWPH-8550EHT08 - Deluxe vs Standard The TWPH-8550EHC08 Deluxe and the TWPH-8550EHT08 Standard share the same 6-turn double-row heat exchanger, 10.45 HP scroll compressor, 312 lb weight, and electrical requirements. The Deluxe adds active cooling via a reversing valve, external bypass valving, and cold plunge capability. The Standard is heating only and costs less upfront. If you are in a warm climate where summer pool temperatures are a genuine issue, the Deluxe pays for itself over a season or two. If you only need heating, the Standard is the right call. TWPH-8550EHC08 - Pool Size and Climate Fit At 137,000 BTU/hr, the TWPH-8550EHC08 is well matched for pools up to around 35,000 gallons in warm climates. In cooler climates, size it for pools up to around 27,000 to 30,000 gallons. For pools that only need heating at this output level, see the TWPH-8550EHT08 Standard. For pools needing heat and cool at a lower BTU, the TWPH-6550EHC08 at 115K BTU is the smaller Deluxe option.

At 137,000 BTU/hr, this unit is well matched for pools up to around 35,000 gallons in warm climates for both heating and cooling. In cooler climates, size it for pools up to around 27,000 to 30,000 gallons. Not sure whether this model or the smaller TWPH-6550EHC08 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-8550EHC08 can lower pool water temperature by 10 to 15 degrees F within 24 hours under typical summer conditions. In Plunge mode, the unit cools down to 44 degrees F, suitable for cold plunge use on volumes in the 500 to 1,000 gallon range. Cooling speed depends on pool volume, ambient air temperature, and pool cover use. What is the difference between the TWPH-8550EHC08 and the TWPH-6550EHC08? The 8550EHC08 delivers 137,000 BTU/hr vs. 115,000 BTU/hr on the 6550EHC08 - about 19% more output. The 8550 uses a 6-turn double-row coil with 16 circuits vs. the 5-turn single-row 9-circuit design in the 6550, a larger 10.45 HP compressor vs. 9.38 HP, and draws 6.7 kW vs. 5.4 kW. Both include external bypass valving, Raymote WiFi, cold plunge mode, and the same 70A breaker requirement. The 8550 is the right choice for pools above 25,000 gallons; the 6550 suits pools up to 25,000 gallons. What is the difference between the Deluxe and Standard TWPH-8550 models? The TWPH-8550EHC08 Deluxe and TWPH-8550EHT08 Standard share the same heat exchanger, compressor, weight, and electrical specs. The Deluxe adds active cooling via a reversing valve, external bypass valving, and cold plunge mode. If you only need heating, the Standard costs less. The Deluxe is worth the premium in warm climates where summer pool temperatures become a problem. What electrical service does the TWPH-8550EHC08 require? The unit runs on 208/230V single-phase, 60 Hz power. Minimum circuit ampacity is 60 amps; recommended breaker size is 70 amps. At 6.7 kW input this is the highest draw in the residential Crosswind V lineup. A licensed electrician should confirm your panel can support the required circuit before installation.
