Air souce heat pump

Air source heat pumps extract thermal energy (heat) from the outside air and convert this into heating and hotwater for your home. Air source heat pumps are designed to work in cold temperatures and are suitable for arange of homes, from a small apartment to a large detached home. Air source heat pumps do require electricity to operate, but 75% of the energy required is generated from the outside air, with only 25% being required fromelectricity. This means that 75% of the energy you use will be from a renewable source, which will reduce youremissions and CO2 impact.

R32 environmental refrigerant

Wotech's new line of heat pumps now utilizes the R32 multifunction series gas solution, providing a number of benefits including:

1. Enhanced environmental performance due to the R32 heat pump's GWP being only one-third that of R410A refrigerant. 

2. High energy efficiency, reaching A+++ energy level according to EU regulation. By utilizing heat from the outside air, the system minimizes energy consumption while maintaining a comfortable environment. The system requires minimal maintenance, ensuring low running costs. Additionally, with inverter technology, energy savings are further maximized.

Why choose R32 Air to Water Heat Pump / Swimming Pool Heat Pump?

Air-to-water heat pumps have become increasingly popular due to their energy efficiency and cost-effectiveness.   These heat pumps extract heat from the air and convert it into usable heat for homes, swimming pools, and other applications. One factor that can significantly impact the performance of air-to-water heat pumps is the refrigerant used.   In this article, we will discuss why R32 refrigerant is an excellent choice for air-to-water heat pumps.

Here is the list of contents:

1.High Energy Efficiency

As well as being energy efficient and cost-effective, an R32 heat pump offers many other benefits. As a result of its ability to recharge and recycle more efficiently than other refrigerants, it can function at much higher efficiency ratings than other refrigerants.

As a result, your regular energy bills will be lower and your performance won't suffer since this heat pump requires less energy to heat and cool your home.   The flow required per unit flow is smaller and the COP is higher since the heat required to evaporate R32 is greater than the heat required to evaporate R410A.

Heat pumps with higher SCOP readings produce more heating capacity per unit of energy used, resulting in higher RHI payments.  In the same heat pump system, R32 can be charged less than R410A because of its lower liquid density.

2.Low Environmental Impact

GWP refers to the greenhouse effect index, which refers to the degree of greenhouse effect damage caused by substances, and is used to express and compare the influence of ozone-depleting substances on global warming.

As shown in the figure, R32 refrigerant has a Global Warming Potential (GWP) of 675, which is about 64% lower than R410A's GWP of 1890. So R32 refrigerant is significantly better than R410A in CO2 emission reduction, and is an ideal choice for consumers who pay attention to environmental protection.

3.Cost Effective

Air-to-water heat pumps that use R32 refrigerant are typically less expensive to run than those that use R410A. The high energy efficiency of R32 refrigerant means that less energy is required to generate the same amount of heat, resulting in lower energy bills.

Additionally, R32 refrigerant is widely available, which makes it more cost-effective compared to other refrigerants that may be difficult to source.

4.Greater Safety

The R32 refrigerant is low-toxic, and does not explode when ignited. By introducing more air conditioning units that use R32, the industry will be able to transition smoothly to a situation where we can still achieve the performance and efficiency that our buildings need, while using equipment and refrigerants that have a much lower global warming potential.


Finally, the R32 refrigerant is future-proof, which means it will not become obsolete anytime soon. As regulations around refrigerants become stricter and consumers demand more eco-friendly products, air-to-water heat pumps that use R32 refrigerant will remain a viable option for years to come.

R32 refrigerant is the latest industry alternative and is expected to replace R410A. It is a hydrofluorocarbon molecule that has several benefits, such as improved energy efficiency, reduced environmental impact, and enhanced safety - all important factors to consider when evaluating refrigerant suitability.   As compared to R410A, R32 outperforms in each index. Additionally, because of anticipated restrictions, you may be required to buy R32 anyway.

Therefore, it might be preferable to use an R32 heat pump initially rather than utilizing a replacement that will eventually be phased out.   Bear in mind that existing heat pumps equipped with R410A cannot be converted and changing the refrigerant should only be done by a trained and certified technician.
