CrestWave Hot Water Recirculating Pump
The CrestWave Recirculating Pump is designed for domestic electric water heating systems. It features a heavy-duty cast iron pump head, aluminum housing, and a polypropylene impeller for durability. The unit provides three adjustable speeds (40/29/20 LPM) and a maximum head of up to 21 feet. It operates at 110-120V with a power range of 46-93W and supports water temperatures from 0°F to 212°F. Quiet operation (about 25 dB) helps maintain household comfort while delivering hot water quickly, reducing waste.
Watts H2O Hot Water Recirculation System
This Watts Premier system uses thermal bypass technology to deliver hot water within seconds at any faucet or shower. The sensor valve opens when the hot side cools, sending cool water back to the heater, and closes when the line hits 98°F. It installs with no return line required and includes a stainless steel pump, 10 ft cord, adapters, mounting hardware, and supply lines. It can save substantial water use (up to 15,000 gallons annually) and requires 120V power with quiet operation.
Riseem Thermostat For Heat Pump Systems
The Riseem thermostat is designed for heat pump and conventional single-stage systems. It supports 2 heat/1 cool configurations and includes a backlit LCD display for easy visibility. It can be powered by 24VAC or two AAA batteries and typically does not require a common wire (C-wire) on most heat pump setups. The unit emphasizes straightforward installation and user-friendly controls, making it a practical option for DIY upgrades.
Aowel 2 Heat/1 Cool Non-Programmable Thermostat
The Aowel AW721 thermostat supports up to 2 heating and 1 cooling stage, making it compatible with many heat pump systems. It is non-programmable but features a white backlit screen for easy operation. The device emphasizes compatibility with systems that require basic, reliable occupancy heat control, and it is straightforward to install in most standard wall openings. Homeowners should verify compatibility with their specific heat pump configuration before purchasing.
HEATIT Electric Heating Cable For Pipes
The HEATIT self-regulating heating cable provides freeze protection for water pipes, ideal for electric heat pump installations in cold climates. It is fully CSA and ETL certified, with a UL-certified plug, and includes a 3-foot power cord plus 35 feet of aluminum tape for simple installation. The cable operates down to -40°F (-40°C) and withstands temperatures up to 194°F (90°C). The durable design supports safe, continuous pipe heating in outdoor or unheated spaces.
Buying Guide
Key considerations for selecting electric heat pump components:
- System compatibility: Confirm that the thermostat and controls match your heat pump’s voltage, wiring, and stage setup. Look for units labeled 2H/1C or multi-stage compatibility.
- Energy efficiency: Choose recirculation pumps and heat cables with low wattage and quiet operation. Variable-speed pumps can save energy while maintaining desired temperatures.
- Safety certifications: Prioritize products with CSA, ETL, and UL listings, especially for electrical components and pipe heating cables.
- Installation complexity: DIY-friendly options save time and cost, but some components may require professional installation, particularly if plumbing or electrical work is involved.
- Maintenance and durability: Select products with corrosion-resistant materials and warranties to ensure long-term performance in varying climates.
- Compatibility notes: Some products (e.g., the Watts recirculation sensor valve) are not designed for tankless water heaters. Verify compatibility with your existing system before purchase.
When evaluating options, consider whether you need instant hot water, basic thermostat control, or enhanced freeze protection for pipes. A combination of an efficient recirc pump, a robust thermostat, and a reliable pipe heater can optimize an electric heat pump system for comfort and savings.
