R32 environmental refrigerant

New Wotech heat pumps have been applied to the new gas solution of the R32 multifunction series.

The advantages are:

  1. Compared to the R410A refrigerant, the R32 heat pump has a GWP of only one-third, so its environmental performance is even better.

  2. High energy efficiency: It reaches A+++ energy level according to EU regulation. By harnessing the heat from the outside air, you use far less energy while still enjoying a steady and pleasant level of comfort. Maintenance requirements are minimal, keeping your running costs low. Thanks to inverter technology, your energy savings are even greater.


The heat pump draws free energy from the air and uses it to heat and cool the building or prepare domestic hot water.

An air source heat pump system for domestic use has become an increasingly favored option for efficient and eco-friendly heating in residences. The process involves extracting warmth from the outside air and converting it into heat or cool air to regulate the temperature inside a building. This renewable energy solution is suitable for both new and old structures, providing year-round comfort while significantly reducing energy bills and carbon footprint when compared to conventional heating systems. Not only are heat pumps cost-effective, but they are also reliable and easy to maintain, making them an excellent choice for homeowners seeking a sustainable energy source for their homes.

The Q&A of air source heat pumps

  1. Q:Will a heat pump provide all the heat needed in the winter?

    A:heat pump ordinarily becomes less effective below 35 to 40 degrees Fahrenheit ambient temperature. Below that, it may be necessary to supplement the heat provided by the heat pump.

  2. Q: How expensive are heat pumps?

    A: The initial cost of heat pump equipment can be 10-15% more than units which use natural or LP Gas for heating, but this difference is minimal when compared to the cost of natural gas or LP Gas service setup.

  3. Q: Do heat pumps have to exchange heat with outside air?

    A: No. Different models of heat pumps can exchange heat with ground water, making them less susceptible to outside air temperature. However, ground water heat pumps are somewhat more expensive to install.

  4. Q: How do I know if my electric heat is on when I'm using my heat pump?

    A: Most heat pump thermostats have a small light or icon which lights when the supplemental electric heater is in use.

  5. Q: On real cold days, my heat pump sometimes has steam coming out of it. Why?

    A: When this condition occurs, your heat pump is going through a "defrost" cycle. The outdoor coil can ice over during cold wet days. When this occurs, the defrost control senses it and automatically initiates a defrost cycle. To accomplish defrost, the reversing valve is switched and the unit is actually in the cooling mode momentarily. The hot refrigerant gas now flowing through the outdoor coil melts the ice away, and the resulting steam is created by the evaporation of the water. A defrost can last one to 10 minutes depending on the unit and the conditions. During this period the electric supplemental heater is automatically activated to temper the indoor air. Expect slightly cooler discharge air during this period.
