The concept of a "pump" is well-known to many, as it involves using energy to enhance mechanical systems—like water pumps that lift water or increase pressure. Similarly, a "heat pump" works by extracting low-grade heat from natural sources such as air, water, or soil and converting it into usable high-quality heat for heating and hot water. This makes it an energy-efficient, environmentally friendly, and clean solution for temperature control. In recent years, heat pump technology has gained global attention as a promising new energy solution.
So, what exactly is a heat pump? Imagine a car that can transport several tons of cargo with just a small amount of fuel. A heat pump operates similarly—it uses a small amount of electricity to "process" heat from the environment, enabling it to provide warmth for homes and daily use.
There are different types of heat pumps, categorized based on their heat source: air-source, water-source, and ground-source heat pumps. Each type utilizes a different medium to extract heat from the surrounding environment.
Is a heat pump water heater considered a solar product? While both are renewable, they operate on fundamentally different principles. Solar products rely directly on sunlight, whereas heat pumps absorb ambient heat from the air, water, or ground. This distinction makes heat pumps more versatile and functional in various weather conditions.
How does a heat pump actually generate heat? It uses a refrigerant, which exists in a liquid state at temperatures below -20°C. This refrigerant absorbs heat from the environment, evaporates in the evaporator, and then gets compressed to raise its temperature. The heat is then released through the condenser, transferring it to the water in the storage tank, thus heating it efficiently.
Does a heat pump require electricity to run? Yes, but only to power the system. Unlike traditional electric heaters that directly heat water, a heat pump uses electricity to move heat from one place to another, resulting in much lower energy consumption.
Compared to other heating methods, heat pumps offer significant advantages: efficiency, energy savings, environmental friendliness, and safety. They don’t produce emissions, don’t use flammable gases, and have lower operating costs than electric or gas heating systems.
What about the initial investment and return on investment? Although the upfront cost may be higher, the energy savings allow for a quick payback within 1.5 years. Additionally, heat pumps typically last up to 15 years, far longer than conventional boilers or heaters.
How much power does an air-source heat pump consume? For example, Tianshu’s air-source units have a thermal efficiency of 300%–500%, meaning they use only 9–15 kWh to produce one ton of hot water, compared to 52 kWh for standard electric heating.
Are heat pumps easy to use? Yes—they come with smart automation systems, allowing users to set the desired temperature and let the system handle everything else. It can even shut down automatically when the temperature is reached or restart when needed.
Can heat pumps work in cold weather? Absolutely. Tianshu models include intelligent defrosting features, ensuring stable operation even in low-temperature environments.
Compared to solar energy, heat pumps offer greater reliability and flexibility. They can operate day or night, regardless of weather, and don’t require large outdoor spaces. Plus, they can also support cooling, dehumidification, and air filtration.
Do you need to refill refrigerant regularly? No, because the system is pre-charged and sealed, eliminating the need for user intervention.
Why are heat pumps more efficient than electric or gas heaters? Because they transfer heat rather than generate it directly, making them significantly more energy-efficient.
How does a heat pump achieve such high efficiency? By using 1 unit of electricity to absorb 2–3 units of free heat from the environment, resulting in a thermal efficiency of 300%–500%.
Do you need a dedicated room for installation? No. Heat pumps are compact, flexible, and can be installed almost anywhere without affecting building aesthetics.
Where can heat pumps be used? They are suitable for residential, commercial, and industrial applications, including hotels, schools, hospitals, swimming pools, and more.
Can multiple heat pumps be connected together? Yes. Tianshu heat pumps feature modular designs, allowing for grid-connected operations where each unit can be controlled independently.
Can heat pumps take advantage of off-peak electricity rates? Yes, with smart scheduling functions that store hot water during low-cost periods.
How should the water tank be sized? It should be based on daily usage, ensuring enough capacity for continuous hot water supply throughout the day.
Are heat pumps reliable? Yes, with built-in protections against overpressure, frost, overheating, and other potential issues.
What are the key features of a residential heat pump water heater? They include pressure-balanced tanks, split designs, microcomputer controls, and customizable combinations to meet individual needs.
How to choose the right water tank size? For a family of 1–2 people, a 150L or 200L tank is recommended; for larger families, larger or multiple tanks are advised.
Compared to boilers, heat pumps offer higher efficiency, lower operating costs, better environmental performance, and safer operation. They also allow for easy expansion as demand grows.
Overall, heat pumps represent a modern, sustainable, and efficient alternative to traditional heating systems, offering long-term benefits for both the environment and the user.
