Raypak Crosswind V Standard Pool/Spa Pool Heat Pump 118K BTU TWPH-6550EHT08 (Heat Only)

The TWPH-6550EHT08 is the third tier in Raypak's Crosswind V Standard series - a vertical-discharge pool heat pump for in-ground and above-ground pools and spas rated at 118,000 BTU/hr. It runs on 208/230V single-phase power, uses a 5-turn titanium heat exchanger, and includes built-in WiFi with the Raymote app for remote temperature control and real-time diagnostics. At a COP of 6.1, it produces 6.1 units of heat for every unit of electricity consumed. Well matched for pools up to around 30,000 gallons in warm climates, stepping up from the TWPH-5550EHT08 at 102K BTU with more output for faster heat-up on larger pools. TWPH-6550EHT08 Crosswind V Standard - Specs and Key Features The TWPH-6550EHT08 runs on 208/230V single-phase, 60 Hz power with a 70-amp recommended breaker and 60-amp minimum circuit ampacity. Water flow range is 20 to 60 GPM, compatible with variable speed pump setups without flow restrictions on most residential systems. The unit weighs 268 lb and connects via industry-standard 2" water connections accessible through the front panel. The 5-turn titanium heat exchanger delivers efficient heat transfer at this output level and resists corrosion from chlorine, salt water, and bromine. TWPH-6550EHT08 Raymote WiFi and VS Pump Control The TWPH-6550EHT08 includes built-in WiFi and Raymote app connectivity out of the box - no separate module or gateway needed. From the app you can monitor temperature, adjust settings, and receive real-time service alerts remotely. The unit also includes variable speed pump control, driving most major VS pump brands directly without additional controllers, plus connections for two actuators and three auxiliary devices. For new pad installations this significantly reduces the hardware needed to automate the full equipment setup. Heat Source Delegation - Pairing the TWPH-6550EHT08 with a Gas Heater Like all Crosswind V models, the TWPH-6550EHT08 includes patent-pending Intelligent Performance Calculations that allow it to coordinate with a secondary heat source - a gas heater, another heat pump, or an electric heater. When paired with a Raypak AVIA gas heater, the system automatically selects the most efficient heat source based on current conditions - heat pump in mild weather when efficiency is high, gas when ambient temperatures drop and heat pump output falls. For year-round pools in climates with cold winters, this combination delivers both efficiency and reliability without any manual switching. Crosswind V TWPH-6550EHT08 - Pool Size and Climate Fit At 118,000 BTU/hr, the TWPH-6550EHT08 is well matched for pools up to around 30,000 gallons in warm climates like Florida, Texas, the Gulf Coast, and the Southwest. In cooler climates - the mid-Atlantic, Carolinas, or Pacific Northwest - a more realistic estimate is 22,000 to 25,000 gallons. Like all air-source heat pumps, efficiency drops as ambient temperature falls; this unit operates most effectively above 50 degrees F. If you need less output, step down to the TWPH-5550EHT08 at 102K BTU or the TWPH-4550EHT08 at 85K BTU. For pools over 30,000 gallons, the TWPH-8550EHT08 at 138K BTU is the top of the Standard range. For pools that also need cooling, see the Crosswind V Deluxe heat and cool models. 5-Turn Titanium Heat Exchanger The TWPH-6550EHT08 uses a 5-turn titanium heat exchanger with 9 circuits on the coil - more surface contact than a basic straight-tube design for more efficient heat transfer at this output level. Titanium resists corrosion from chlorine, salt water, and bromine, making it the right choice for salt chlorine generator pools and coastal installations where standard copper heat exchangers degrade faster.

At 118,000 BTU/hr, this unit is well matched for pools up to around 30,000 gallons in warm climates. In cooler climates, size it for pools up to around 22,000 to 25,000 gallons. When in doubt, sizing up is almost always the right call - a slightly larger unit runs less frequently, uses less electricity over time, and has a longer compressor lifespan. Not sure which model fits your pool? Contact us and we will help you figure it out before you buy. Does this model heat only, or does it also cool? Heat only. The TWPH-6550EHT08 is a standard heating unit. The "EHT" designation in the model number indicates electric heat, top discharge - no cooling capability. If you need cooling - useful in Florida and other warm climates where pool water can climb into the 90s in summer - look at the Crosswind V Deluxe heat and cool models instead. What electrical service does the TWPH-6550EHT08 require? The unit runs on 208/230V single-phase, 60 Hz power. Minimum circuit ampacity is 60 amps; recommended breaker size is 70 amps - note this is a 70-amp breaker, one step up from the 60-amp requirement on the smaller 4550 and 5550 models. A licensed electrician should handle the electrical connection and confirm your panel can support the required circuit before installation. Does this heat pump work with a variable speed pool pump? Yes. The Crosswind V includes built-in variable speed pump control compatible with most major VS pump brands without additional controllers. The 20 to 60 GPM flow range accommodates the lower flow rates typical of VS pumps running at reduced speeds. An optional bypass valve kit is available for setups where flow might otherwise exceed 60 GPM. What is the difference between the TWPH-6550EHT08 and the TWPH-5550EHT08? The TWPH-6550EHT08 delivers 118,000 BTU/hr vs. 102,000 BTU/hr on the 5550 - about 16% more output. The 6550 uses a larger 9.38 HP compressor vs. 7.85 HP on the 5550, and draws 5.4 kW vs. 4.8 kW. Both models use a 5-turn titanium heat exchanger and include built-in Raymote WiFi, VS pump control, and heat source delegation. The 6550 is the right choice for pools in the 25,000 to 30,000 gallon range; the 5550 is better suited for pools up to 25,000 gallons.
