Product Features

1. Instant Hot Water, Water & Time Saving It solves the problem where the water heater is far from water outlets. There is no need to drain large volumes of cold water in the pipeline. Hot water comes out immediately once you open the tap, saving water resources and cutting waiting time.
2. Multiple Intelligent Activation Modes It supports water flow sensor startup, remote control startup and forced manual startup. Timed constant temperature can be set for multiple periods throughout the day. You can preset working time windows, and the unit automatically maintains hot water temperature in pipelines to fit different living habits.
3. Durable Materials & Reliable Motor The housing is integrally injection-molded from high-strength engineering plastic with fine craftsmanship and a neat, elegant appearance. It adopts a sealed motor for stable operation, high safety and long service life. All wetted components are made of solid copper to resist corrosion, deliver cleaner water and protect your family’s health.
4. Large Touch Screen Operation Equipped with a large display and touch keys. Temperature, runtime and working modes are clearly displayed. Parameters can be adjusted easily and intuitively, simple enough for the elderly to operate.
5. Wide Compatibility Compatible with gas water heaters (≤16L), air-source water heaters, electric water heaters, wall-hung boilers and solar water heaters, matching most domestic hot water systems.
6. Low Power Consumption & Quiet Operation Rated power is only 55W for low energy consumption. The pump runs quietly without disturbing your home environment. IP21 protection class meets safety standards for indoor installation.

Application Scenarios

1. Large apartments, duplex houses and villas: Homes where the water heater is installed in the kitchen or utility room, while bathrooms are far away with long pipelines and long waiting time for hot water.
2. Homes with multiple water outlets: Houses with several bathrooms and balcony hot water taps requiring frequent hot water supply.
3. Support for various domestic hot water systems: Retrofit and upgrade hot water systems including gas, electric, solar, air-source water heaters and wall-hung boilers with recirculation pumps.
4. Water circuit renovation for old houses: Add the recirculating pump to existing water heater systems without major wall breaking, to achieve zero cold water experience.Note: A return pipeline is required for some installation cases. A one-way valve can be adopted for sites without return pipes.

Maintenance Instructions

1. Check pipeline connections regularly: Inspect the G1/2 threaded inlet and outlet joints every 6 months. Check for seepage or dripping. Tighten connectors or replace sealing rings when needed.
2. Water quality maintenance: If local tap water is hard, clean pipeline filters periodically to reduce limescale buildup. Limescale will reduce pump flow and head and damage the impeller.
3. Long-term shutdown storage: Cut off power supply if the pump will not be used for an extended period. In cold environments, drain all residual water inside the pump to prevent cracking caused by freezing.
4. Motor maintenance: The sealed motor is maintenance-free. Do not disassemble the motor by yourself. In case of abnormal noise or startup failure, cut off power and contact professional technicians for repair.
5. Housing cleaning: Wipe the casing and control panel with a dry soft cloth after power cut. Do not spray water directly onto the pump body or display screen.

Usage Precautions

1. Power supply: Use 220V / 50Hz mains power with reliable grounding. Do not touch the panel or plug/unplug the power cord with wet hands to avoid electric shock hazards.
2. Medium limitation: Only for domestic hot water transportation. Not suitable for oil, acid, alkali or wastewater with impurities. The working medium temperature shall not exceed the temperature grade of the equipment.
3. Pressure limitation: System water pressure shall not exceed the maximum working pressure of 1.0MPa. Overpressure will damage pump seals.
4. No dry running: Ensure pipelines are fully filled with water before startup. Dry running is strictly forbidden as it can easily burn out the motor.
5. Installation location: For indoor installation only. Do not install outdoors exposed to rain. Keep the installation area well ventilated and avoid long-term direct sunlight.
6. Compatibility restriction: Only match gas water heaters of 16L or smaller. This HBS-12 model is not recommended for large-capacity water heaters.
7. Fault handling: If abnormal noise, water leakage or startup failure occurs, cut off power immediately, close water valves, stop operation and contact professional maintenance personnel. Do not disassemble and repair it yourself.
