What Is an Air to Water Heat Pump?
Air to water heat pumps provide both cooling and heating to a house. People who live in a place with moderate weather conditions, this pump will be a boon. They offer up to thrice the thermal energy to the house than what it consumes. One of the reasons why these pumps are so efficient is they don’t work like regular combustion heating systems. Instead of transforming fuel to energy, the pump automatically transfers heat to keep the house warm.
What Are the Benefits of Air to Water Heat Pumps?
Everyone is concerned about global warming and how to keep the environment safe. One way to do that is by using renewable energy. Air to water heat pumps follow this technology due to which it is not only saving the environment but also the user’s money. If the air to water heat pump is installed correctly, it can reduce the annual heating costs by almost 50%. There are several other reasons why air to water heat pumps are so popular among users:
Air to water heat pumps requires very low maintenance. Compared to combustion heating systems, these units only need a yearly checkup, and that’s all. If the homeowner hires a professional for maintenance, he/she may need the technician once in three years.
Low Running Costs
As already mentioned, air to water heat pumps are more energy efficient. That is why they are cheaper to run. Many people think that high initial cost also means high operating cost. But that is not the case. The long-term savings on electric bills will recover the investment as they can save almost £1,400 every year.
Carbon emission from combustion-based heating systems is a significant concern for the environment. However, air to water heat pumps reduces carbon emissions to a great extent. The high conversion rate of energy is one of the reasons why carbon is not involved in these units. Air to water heat pumps can reach 600% efficiency without using carbon.
Apart from providing warmth during winters, air to water heat pumps also cool the rooms down during summers. They successfully reverse their process, and the heat pump turns into an air conditioner. Users can quickly switch to cooling mode whenever the temperature is on the higher side.
Air to water heat pumps usually last for around 50 years. But, they come with a life of 14 to 15 years. Users can expect them to last for a long time if they take care of it correctly.
Understanding How Air to Water Heat Pumps Work
The mechanism of air to water heat pumps is simple. They use energy from air that generates heat using a water-based heating system. The pump contains a chemical liquid that evaporates when heat from the air enters the unit. Soon, the compression pump will extract the liquid generated by the steam generator, transferring it to a much smaller space. This automatically creates a forward thrust that also leads to an increase in temperature. As soon as the liquid reaches 100 degrees Celsius, it shifts into the steam condenser.
Two things contribute to the quick heating process: the room temperature that cools down the steaming liquid and the water present in the heating system. When the cold fluid enters the vent responsible for lowering the steam generator pressure, it creates the much-need heat.
What to Consider Before Purchasing an Air to Water Heat Pump?
Purchasing an air to water heat pump is a significant investment. That is why it is wise to consider a few factors before buying the unit:
Contact the Electricity Supplier
Like air conditioners, air to water heat pumps also requires permission from the electricity supplier. People need to confirm if they need to make any changes to their existing electric system in the house before installing the air to water heat pump.
One of the reasons why air to water heat pumps are considered expensive is they include the introduction and installation costs. So, make sure that the seller doesn’t charge extra for installations.
Size of the Heating System
The size of the heating system and air to water heat pump will determine how much energy and money users are saving every month. The bigger the heating system, the more the user saves. Also, the humidity in the air around the house affects the energy-saving goals.
Once the installation is complete, make sure it is tested by a professional. This will assure that the unit will last for a long period. The inspector should provide detailed instructions on various tips to maintain the air to water heat pump.
Installation and Maintenance of an Air to Water Heat Pump
It hardly takes a few hours to install the air to water heat pump. But, users should always contact a professional to install the unit. If installation costs are not included during the purchase of the air to water heat pump, they will have to get in touch with an expert who can install these pumps. Always provide an open space to install the external unit of the air to water heat pump so that air can circulate freely. The air that passes from this part shouldn’t hit a wall and enter it again. On the other hand, the indoor unit should be installed in the room that the user uses the most.
Maintenance is easy when it comes to air to water heat pumps. Although they come with a 3 to 4-year warranty, they last for more than 14 years. Some of the expensive models have lasted for approximately 50 years. However, a yearly checkup is a must if the user wants it to last that long. Call a professional who will check the parts thoroughly every year.
