Varpoolfaye vs GRAT Heat Pump Specs
Heating Capacity
The Varpoolfaye model delivers 90,000 BTU of heating power, while the GRAT unit provides 75,000 BTU. This higher output suggests the Varpoolfaye can raise water temperatures faster or maintain them more effectively in colder conditions. Both units utilize inverter technology to modulate compressor speed for energy efficiency. The Varpoolfaye also lists a Coefficient of Performance (COP) of 12.5, indicating strong energy conversion. You should choose the Varpoolfaye if you need maximum heating speed for larger volumes or colder climates. The GRAT remains efficient but with a lower peak output rating.
Pool Capacity
Capacity ratings differ significantly between these two units. The Varpoolfaye is designed for pools up to 25,000 gallons, making it suitable for larger inground installations. The GRAT is rated for pools up to 21,000 gallons. This four-thousand-gallon difference matters if you have a large volume of water to heat. Both units support both inground and above-ground configurations. However, the higher capacity rating of the Varpoolfaye gives it a clear advantage for larger setups. If your pool exceeds 21,000 gallons, the GRAT may struggle to maintain desired temperatures efficiently.
Connectivity
Both units offer smartphone control via WiFi, but the GRAT includes an additional Bluetooth feature. The GRAT requires Bluetooth for initial device pairing before establishing a 2.4GHz WiFi connection. This dual connectivity can simplify the setup process for some users. The Varpoolfaye lists WiFi app control for remote adjustments and scheduling but does not mention Bluetooth support. Both allow you to monitor and change settings from anywhere. If you prefer a setup method that uses Bluetooth for easier initial pairing, the GRAT has the edge. Otherwise, both provide comparable remote management capabilities.
Operational Modes
The GRAT unit supports both heating and cooling modes, with a cooling range of 45°F to 82°F. This allows you to lower the water temperature during hot summer months. The Varpoolfaye data only specifies heating functionality with a range up to 104°F. It does not list cooling capabilities. If you live in a region with very hot summers and want to chill your pool water, the GRAT is the only option here. For pure heating performance, both units are effective, but the GRAT offers greater versatility with its dual-mode operation.
Noise Level
Noise output is a practical consideration for backyard comfort. The Varpoolfaye operates at 47 dB, while the GRAT runs at approximately 50 dB. The difference of three decibels is measurable but may not be noticeable in all environments. Both units are designed for quiet operation suitable for residential pools. The Varpoolfaye has a slight advantage in terms of lower decibel rating. If you place your hot tub or pool very close to seating areas or bedrooms, the quieter Varpoolfaye might be preferred. However, both are relatively quiet for outdoor equipment.
Which pool heat pump fits you
Owner of a large 25,000 gallon inground pool
The Varpoolfaye handles pools up to 25,000 gallons, while the GRAT maxes out at 21,000. You get 90,000 BTU of heating power, which is higher than the GRAT’s 75,000 BTU. This extra capacity helps maintain temperature in larger volumes of water. It also includes a 118-inch power cord, simplifying installation for deeper or more distant pool setups.
User wanting both heating and cooling functions
The GRAT unit offers both heating and cooling operational modes. You can lower water temperature between 45°F and 82°F. The Varpoolfaye data does not mention cooling capabilities. If you need to cool your pool during hot months, this dual-function feature is essential. It also includes Bluetooth for initial pairing alongside WiFi.
Buyer prioritizing quiet operation and corrosion resistance
The GRAT operates at approximately 50 dB. The Varpoolfaye is rated at 47 dB. While the Varpoolfaye is slightly quieter, the GRAT features a titanium heat exchanger. This material provides excellent corrosion resistance for both freshwater and saltwater pools. The GRAT also has a UV-resistant ABS housing, protecting against fading and cracking over time.
