What is heat pump geyser?
The heat pump geyser takes heat from the air and transfers it to the hot water. Therefore, they are also called "air source heat pumps". They run on electricity but are about three times more efficient than traditional electric water heaters. When used in the right environment, they can save energy, save money and reduce greenhouse gas emissions.
How does heat pump geyser work?
The geyser with heat pump is an excellent choice for saving electricity and reducing your electricity bills. When a refrigerator cools the things it keeps inside it by absorbing heat and venting it outside, a heat pump works just the opposite way. That is, it absorbs heat from its surroundings and uses it to heat water. It also has refrigerant gas like air conditioner which flows in pipes connecting different internal components of heat pump geyser.
These geyser absorb heat from the air and transfer it to the water in the reservoir, raising the temperature of the water and releasing cool air outside. This is why people feel cooler around these types of water heaters. In fact, it can actually be used to cool the air as well. The geyser with heat pump not only heats the water, but also very efficiently and quickly. This is because in addition to the electricity they consume, they also draw heat from the air to heat the water.
Energy efficiency of heat pump geyser:
If you want to save power, heat pump geyser is the best choice. This is due to its increased efficiency, because in addition to consuming electricity, it also draws heat from its surroundings to heat the water. So this means that the same amount of water will be heated in less time than a normal water heater because the heat pump geyser consumes more total energy.
If a normal water heater consumes 1 kW to heat a given amount of water, then the heat pump geyser draws a total of 2.5 kW from the environment while consuming the same 1 kW of electricity on average, in addition to 1 kW. This means that the heat pump geyser provides 3.5 kW output (1 kW + 2.5 kW) to heat the same amount of water while consuming the same 1 kW of electricity. Note that this value (2.5 kW) may vary depending on the brand or specification of the product you are purchasing. It can be lower than 2.5 kW or higher than 2.5 kW. It all depends on the heater you buy. Therefore, it is recommended that you understand the specifications of the product in detail before purchasing.
Advantages of heat pump geyser:
1. You will save a lot of money on heating water in the long run
2. The heat pump produces almost 5 times the energy needed to operate
3. Considered environmentally friendly as it requires little energy
4. In extremely low temperatures, the electric assist system kicks in to ensure the water stays hot
5. No need for solar panels or extra roof space
6. Very low installation time and cost as it uses typical electrical connections
Does heat pump geyser work in cold climates?
The heat pump geyser draws in ambient air and heats it inside the system. If the surrounding air is cold, heat pumps will have to work harder to heat it, reducing their efficiency in cold climates. They are ideal for work in year-round temperatures ranging from 4°C to 32°C.
Also, heat pump geyser tends to cool the space around them as cold air is expelled while hot air is retained inside the heater. This means that in winter you will have a heat pump geyser that can further cool your space.
However, if you have a furnace house with a wood-fired or oil-fired boiler, you can also install a heat pump geyser there, so it absorbs the heat lost by the boiler.
Install heat pump geyser
The correct installation of the heat pump geyser depends on many aspects. Some of these factors include your home's layout, climate, and local building codes. Therefore, it is recommended that you have a qualified plumbing and heating contractor who can install your heat pump to the proper standards.
The heat pump geyser requires at least 28.3 cubic meters of air space around the exact water heater. Exhaust cold air can be exhausted indoors or outdoors, but it is best to install it in a hot spot, such as a furnace room. The heat pump geyser can be a bit noisy, which is another reason why putting it in the furnace room would be a good solution. Installation time is about 1 - 3 days to allow extensive design and planning processes.
The heat pump geyser is a huge innovation in home appliances, especially those that consume little electricity. So if you want to use warmer water for less money, a heat pump geyser is something you don't want to miss.
