What is a heat pump water heater and how does it work

Heat pump water heaters are innovative appliances that offer an energy-efficient solution for heating/cooling in homes and commercial buildings. These systems use advanced technology to extract heat from the surrounding air and transfer it to the water, reducing energy consumption and lowering costs.

Introduction of heat pump water heaters

Electric heat pump water heaters are among the most efficient water heaters, operating by transferring heat energy rather than directly generating heat. They absorb heat from the environment (various sources like air, water & earth) and then pass it onto the water in the tank using a refrigeration process. Since they require only electricity for heat exchange, they enable energy savings.

There are two types of heat pump systems - split systems and integrated systems.

Split System - The evaporator, fan and compressor are separate and connected to the tank through refrigerant piping.

Integrated Systems - In an integrated system, the entire system is connected ( tank, compressor) and comes as a single unit.

Wotech Heat pump water heaters supply the split system,offer an energy-efficient solution for house heating,cooling and domestic hot water in homes and commercial buildings.

The working principle of heat pump water heaters

A heat pump works in the same way as a reverse-cycle air conditioner. Instead of heating the room, it heats the water.Here are a few simple steps on how a heat pump works:

• The heat pump system works by moving heat from the air in the room to the water in the tank.

• The fan draws air onto fins called evaporators.

• The heat in the air is absorbed by a refrigerant that flows through an evaporator.

• The refrigerant is then compressed into a vapour, which raises the temperature and pressure.

• The hot vapor then flows through a heat exchanger, which heats the water and cools the refrigerant.

• Once the vapour refrigerant has given all its heat, it is then transformed into its liquid state and cycled up to start again at the evaporator.

Wotech heat pump water heater is reversible,can heat or cool buildings and, in some cases, supply domestic hot water as well.

However, you may need bigger radiators or underfloor heating to make the most of this system as the output is cooler than from a traditional boiler or furnace.
