Description
Core Performance and Series Positioning: This model is the most powerful Heat-Only version in the Crosswind V series, with a heating capacity of 138,000 BTU/h (138 MBTU/h). A corresponding Heat/Cool dual-mode version exists in the same series (TWPH-8550EHC10), while the EHT10 suffix indicates it is heating-only. Based on industry sizing guidelines, this capacity can serve pools of approximately 27,000 to 40,000 gallons, depending on climate, shading, and usage habits. COP ranges between 5.8 and 6.1, delivering excellent energy efficiency.
Vertical Discharge and Compact Design: It features the Crosswind V signature vertical discharge design, where air is expelled upward from the top rather than sideways, making the unit more compact and suitable for space-limited equipment areas while reducing airflow interference with surroundings. The unit weighs approximately 286 lbs and can be installed on a standard equipment pad. It is compatible with industry-standard 2-inch plumbing connections, and all connections are accessible from the front panel for easy servicing.
Smart Control and Automation: It includes a built-in Wi-Fi module, allowing remote temperature adjustment, schedule setting, and service alert reception through the Raymote mobile app. It features a capacitive touch control panel with clear, easy-to-read diagnostic information, and real-time status notifications pushed directly to users and service technicians. The Operation Manager supports out-of-the-box control of up to 6 devices: 2 valve actuators, 3 auxiliary devices, and 1 pump, and is compatible with most variable-speed pumps (VS Pumps) on the market.
Smart Energy Management: It supports hybrid heating control, able to work with a Raypak AVIA gas heater to automatically switch between the heat pump and gas heater based on pool water conditions, maintaining the set temperature in the most energy-efficient way.
Maintenance Convenience: The control junction box (J-box) can be quickly removed, and together with the extended control wiring harness, it makes inspecting and cleaning internal components easy. It features a powder-coated steel cabinet, more durable than plastic housings, while also protecting the evaporator coil. The four-blade fan design reduces operating noise.
Electrical and Core Technology: It uses a 208-230VAC single-phase 60Hz power supply, with an operating power of approximately 6.6 kWh, a minimum circuit ampacity of 46A, and a recommended breaker of 60A. It uses R-410A refrigerant, a spiral titanium tube heat exchanger (corrosion-resistant, suitable for saltwater pools), and a scroll compressor.
Product Line Cross-Reference: This model corresponds to TWPH-8550EHT08 in the Raypak brand line and TWPH-8550EHT11 in the Ruud brand line, all being different brand versions of the same product.
