Domestic Hot Water Air‑Source Heat Pump
1. How does a domestic air‑source hot water heat pump work?
It extracts heat energy from surrounding air and transfers the heat into water. Instead of generating heat directly by electricity, it consumes only a small amount of power to run the compressor, so it achieves high energy‑saving effect for home hot‑water supply.
2. How much can it save compared with electric water heater?
Under normal conditions, its COP is above 3.0. It only consumes 1 unit of electricity to produce heat equivalent to more than 3 units of electric heating. It can cut household hot‑water electricity cost by about 60‑70%.
3. Can it work in cold winter?
Standard model works stably above ‑5℃. Choose EVI enhanced vapor‑injection model for cold climate, which can operate reliably down to ‑25℃ and guarantees hot‑water output in freezing weather.
4. What hot‑water temperature can it reach?
The regular working temperature range is 40‑55℃, which fully meets household bathing and cleaning requirements.
5. Does it need to connect to solar water tank?
Not required. It can work independently with its matched storage tank. It also supports connecting with existing solar water tank to realize solar‑heat pump complementary system.
6. Is backup electric heating necessary?
Most units come with built‑in auxiliary electric heating. It will auto‑start under extreme low‑temperature or high‑peak water‑use conditions, ensuring continuous hot‑water supply for family.
7. What are installation requirements?
The outdoor unit needs well‑ventilated space, can be installed on balcony, ground or outdoor wall. The water tank shall be placed indoors or sheltered outdoor area. Professional technicians are required for piping connection and commissioning.
8. Will it make loud noise at home?
Modern units adopt low‑noise fan and compressor structure. Normal running noise is around 50‑58dB, similar to household air‑conditioner outdoor unit, will not disturb daily rest.
9. What daily maintenance should be done?
• Clean the evaporator coil surface of outdoor unit once a year, remove dust and fallen leaves.
• Check water filter, water pressure and pipe connections regularly.
• Have professional personnel inspect refrigerant circuit every 1‑2 years.
10. Is it safe for family use?
Yes. Heat pump realizes isolation between electricity and water. No open‑fire combustion risk. Equipped with multi‑layer safety protections including over‑temperature, over‑pressure and anti‑freeze functions for household application.
11. Can I control it by mobile phone?
Yes. Models with WiFi module support mobile APP remote control. You can set temperature, timing mode and check running status remotely.
12. Do you support OEM & ODM?
Yes. Custom logo, tank capacity, casing color and controller program are acceptable for bulk wholesale orders.
