Aquastrong 18,000 BTU Pool Heat Pump
The Aquastrong 18,000 BTU heat pump is positioned for medium-sized above-ground pools and small inground systems. Its listed features emphasize dual-mode temperature control for heating between 59–104°F and cooling between 59–83°F, allowing season extension and year-round water management.
Performance notes from the spec sheet include a high-output 18,000 BTU heating module and a precision thermostat with ±2°F accuracy. Aquastrong claims the unit is designed for 5,000-gallon pools, though the product listing cites suitability up to 6,500 gallons depending on climate and insulation.
On efficiency, the unit advertises a 5.5 COP and a reduction in energy use versus conventional electric heating. For purchasers, consider installation space, local ambient temperature (heat pumps are less effective in very cold climates), and integration with existing pool plumbing and electrical service.

The Aquastrong 75,000 BTU Inverter targets large pools and colder environments with a wide operating range from 47–104°F for heating and 47–83°F for cooling. The product calls out rapid heating capability, WiFi app control and scheduling, which supports remote temperature management.
Key technical highlight: full DC variable frequency inverter delivering up to a reported 15.8 COP, which indicates high theoretical efficiency and smoother modulation between output levels. The inverter design can reduce on/off cycling and adapt power draw to demand.
Buyers should verify that their electrical service (220V) and breaker capacity match the unit’s requirements. For large-capacity heaters, evaluate noise, compressor size, and local permitting for outdoor mechanical equipment.
VARMINPOOL 16,000 BTU Pool Heat Pump
The VARMINPOOL 16,000 BTU model is specified for pools up to around 5,400 gallons and highlights an energy-saving inverter with built-in WiFi for app control. The feature list mentions a titanium heat exchanger, which is beneficial for chlorine and salt pools due to resistance to corrosion.
Inverter operation allows continuous modulation and can improve run-time efficiency. The integrated app control enables schedules and remote monitoring. As with most heat pumps, performance will depend on ambient temperature and pool insulation, so use the manufacturer’s pool-size guidance as a baseline.

When evaluating this type of unit, confirm installation clearances for airflow around the cabinet and that your circulation pump flow rate aligns with the heater’s water-side requirements.
Dr Infrared Heater DR-1100HP 110,000 BTU Inverter Heat Pump
The Dr Infrared DR-1100HP is a high-capacity inverter heat pump designed for very large pools (up to 32,000 gallons as listed). It features full DC inverter technology with variable capacity from roughly 20% to 100%, allowing more efficient operation across a range of conditions.
Manufacturing certifications like CSA and AHRI are noted, which can be important for validating performance claims and meeting local codes. The unit advertises a broad input voltage range (208–230V) and a compressor design aimed at stability and reduced vibration.
Prospective buyers should plan for heavy-duty electrical service and evaluate physical footprint, weight, and the need for a concrete pad or vibration isolation. Certified performance can simplify comparisons when sizing equipment and estimating energy consumption.
WOPOLTOP 100,000 BTU Full Frequency Conversion Heat Pump
The WOPOLTOP 100,000 BTU unit targets large residential or small commercial pools with a recommended maximum of about 26,000 gallons. It emphasizes full frequency conversion (full inverter) design and a reported COP up to 6.8, indicating high theoretical efficiency under optimal conditions.
Features include dual heating/cooling functionality and WiFi-enabled control for remote operation. The listing highlights advanced compressor components and continuous modulation to avoid frequent cycling, which supports longevity and energy savings.
For buyers, confirm that on-site electrical infrastructure supports the unit’s 220–240V requirement and that site layout allows adequate airflow and service access. Large units also commonly require professional installation and possible local permits.
Buying Guide: How To Choose The Best Electric Heater Pump
Selecting the right electric heater pump requires comparing capacity, efficiency, controls, installation constraints, and long-term operating costs. Below are the most important considerations and comparison perspectives to ensure an informed purchase.
Pool Size And Heating Capacity
- Match BTU To Pool Volume: Use manufacturer recommendations as a starting point. Oversizing wastes capital and may reduce efficiency; undersizing fails to maintain target temperatures.
- Consider Climate: Cold ambient air reduces heat pump output. In cooler climates, choose a higher-capacity or inverter model to maintain set temperatures.
Energy Efficiency And COP
- COP (Coefficient Of Performance): Indicates heat output per unit of electricity. Higher COP values typically mean lower operating costs under similar conditions.
- Inverter vs Fixed-Speed: Inverter/full frequency conversion units modulate output, reducing cycling and improving part-load efficiency. They are often more efficient and quieter but cost more upfront.
Heat Exchanger Material
- Titanium: Best for saltwater or chlorinated pools due to corrosion resistance.
- Copper/Aluminum: Common in budget units but may be prone to corrosion in harsh chemistries.
Controls And Connectivity
- WiFi/App Control: Allows remote scheduling and monitoring. Useful for automated pool management and troubleshooting.
- Built-In Timers & Thermostats: Evaluate accuracy and ease of programming; ±2°F accuracy is common on many models.
Installation And Electrical Requirements
- Voltage: Small units typically run on 120V; larger units require 220–240V. Confirm breaker and panel capacity beforehand.
- Placement: Heat pumps require clearance for airflow and maintenance. Install on a stable pad and allow manufacturer-recommended clearances.
- Plumbing Compatibility: Check required water flow rates and plumbing adapters.
Durability, Certifications, And Serviceability
- Certifications: AHRI/CSA listings give validated performance metrics and support comparisons.
- Warranty & Parts Availability: Consider ease of obtaining replacement parts, compressor warranties, and local service providers.
- Noise And Vibration: Inverter models often run quieter. Review fan and compressor descriptions if noise is a concern for the site.
Operational Costs And Seasonal Use
- Estimate Energy Use: Multiply expected run hours by electrical draw and local rates. Inverter units modulate to demand and can reduce energy consumption during shoulder seasons.
- Pool Insulation: Use covers and reduce heat loss at night to decrease run times and energy costs regardless of heater size.
Comparison Perspectives
- Small Above-Ground Pools: Look at compact 12k–18k BTU units on 120V circuits that balance footprint and cost.
- Large Inground Pools: Consider 75k–110k BTU inverter units with 220–240V service, frequency conversion, and titanium exchangers for durability.
- Cold Climates: Prioritize inverter models and higher-capacity units; verify minimum operating ambient temperatures and defrosting capability.
- Saltwater Pools: Prioritize titanium heat exchangers and corrosion-resistant housings.
Practical Checklist Before Buying
- Confirm pool volume and target temperature rise goals.
- Verify electrical service capacity and breaker compatibility.
- Check recommended clearances and mounting requirements.
- Ensure compatibility with pool chemistry (titanium for saltwater).
- Compare COP values and inverter features for long-term savings.
- Look for certifications (AHRI, CSA) and warranty terms.
Using the product overviews and buying guide, narrow choices by objective criteria like pool size compatibility, efficiency (COP), inverter capability, heat exchanger material, and electrical requirements. These factors provide a practical, comparable framework to select the best electric heater pump suited to your pool and local conditions.
