WARMBLU 23,000-Gallon Inverter Pool Heat Pump
The WARMBLU 23,000-Gallon Inverter Pool Heat Pump targets large inground pools with 220V power. It matches the ACiQ’s inverter technology for efficiency but focuses on high-capacity performance for larger volumes.

It shares the quiet, app-controlled operation you expect from premium inverter units. The WARMBLU is a solid choice if you need robust heating for a large pool and have the necessary electrical infrastructure. It gives up the ACiQ’s wider pool capacity range but delivers strong, efficient performance for its target size.

The Varpoolfaye is a good choice if you want smart features and efficiency but can sacrifice some heating speed. It is best for homeowners who prioritize cost and quiet operation over maximum power output for large pools.
Varpoolfaye 40000 BTU Pool Heat Pump
The Varpoolfaye 40,000 BTU Pool Heat Pump is designed for small pools up to 12,000 gallons. It is significantly smaller and less powerful than the ACiQ, offering only 40,000 BTUs. It includes smart controls and inverter technology for energy efficiency. The compact size makes it ideal for small pools where a 120,000 BTU unit would be overkill. It requires 220V power. This model is best for users with small pools who need reliable heating and cooling without the bulk or cost of a larger unit. It gives up the ACiQ’s high capacity but provides a practical, efficient solution for smaller water volumes.
NATURAQUELL 90,000 BTU Inverter Pool Heat Pump
