The AQUASTRONG HEX035TOP heat pump uses a top-discharge design to fit tight spaces while maintaining a 12 COP rating for energy efficiency. If you need more heating power, a different footprint, or smart app control, these aquastrong hex035top heat pump alternatives may better suit your pool. This list covers 6 models that share key specifications with the original unit. We selected them because their specs overlap with the HEX035TOP in areas like inverter technology, pool capacity, or voltage requirements. Each option offers a distinct combination of BTU output, physical dimensions, and connectivity features. You might choose a larger unit if your pool exceeds 32,000 gallons or if you require both heating and cooling cycles. Some alternatives provide app-based temperature management, while others focus on raw output for colder climates. The following products are ranked by how well they match common needs that differ from the HEX035TOP. You can compare their published specs to find the right balance of size, efficiency, and control for your specific setup.
Comparing Key Alternatives
AQUASTRONG Dual-Mode Inverter Pool Heat Pump
The AQUASTRONG HEX100 offers app-based dual-mode control, which the HEX035TOP lacks. It targets pools up to 20x43 feet with a 117-pound frame. The HEX035TOP relies on a top-discharge design for tight spaces, while the HEX100 uses a standard footprint. You gain smart management here but lose the compact vertical airflow advantage. If you need remote temperature adjustments for a medium-sized inground pool, this model provides that connectivity. It is a practical choice for users who prioritize app control over space-saving ventilation.
Varpoolfaye 140k BTU Inground Pool Heat Pump
The Varpoolfaye unit delivers 140,000 BTU of heating power, significantly exceeding the HEX035TOP’s 110,000 BTU output. It supports pools up to 42,000 gallons, making it suitable for larger installations. The unit measures 28.7 inches wide and 38.6 inches tall, requiring more floor space than the HEX035TOP. You trade compactness for raw heating capacity and smart control features. This alternative fits owners of large inground pools who need faster heat recovery and do not have space constraints. It is a robust option for high-demand heating scenarios.
VARMINPOOL 140,000 BTU Inverter Pool Heat Pump
The VARMINPOOL heater provides both heating and cooling capabilities, a feature absent in the HEX035TOP. It handles pools up to 22x44 feet with a 140,000 BTU output. The unit weighs 275 pounds and measures 28.7 inches wide, making it substantially heavier and larger than the HEX035TOP. You gain year-round temperature regulation and smart control but sacrifice the compact, quiet operation of the top-discharge model. This choice suits large pool owners who need versatile climate management and have ample space for a heavier, more powerful unit.
WARMBLU 33k Gallon Inverter Pool Heat Pump
The WARMBLU heat pump targets large pools up to 33,000 gallons with a focus on quiet operation. It measures 29.2 inches wide and 43 inches tall, offering a different footprint than the HEX035TOP. While the HEX035TOP uses a top-discharge design for tight areas, this model prioritizes app control and energy efficiency for larger spaces. You gain smart connectivity and high efficiency but lose the space-saving vertical airflow. This alternative is ideal for users with larger inground pools who value remote management and quiet performance over compact installation options.
DOEL 58,000 BTU Inverter Pool Heat Pump
The DOEL CIP-35SE provides 58,000 BTU of heating power and supports pools up to 30,000 gallons. It includes app control and cooling functions, which the HEX035TOP does not offer. The unit measures 43 inches long and 29 inches tall, requiring more space than the HEX035TOP’s compact design. You gain smart features and dual-mode climate control but sacrifice the top-discharge ventilation that aids tight installations. This model suits large pool owners who need versatile temperature management and have the space for a larger, feature-rich unit.
DOEL 44000 BTU Inverter Pool Heat Pump
The DOEL CIP-13SE is designed for smaller pools, supporting sizes up to 14x23 feet. It delivers 44,000 BTU of heating power, which is lower than the HEX035TOP’s 110,000 BTU output. The unit includes app control for smart management, a feature the HEX035TOP lacks. You gain precise remote temperature adjustments but lose significant heating capacity and the top-discharge design. This alternative fits owners of small-to-medium pools who prioritize smart control and energy efficiency over raw heating power and compact ventilation options.
