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.

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


Introduction to heat pump

Heat pumps are an essential component of HVAC systems, providing efficient heating and cooling solutions for both residential and commercial buildings.  when it comes to the electricity they consume, one of the most important considerations is whether to opt for a single-phase or three-phase heat pump.

Difference Between Single-Phase & Three-Phase Heat Pumps

Clearly, there are numerous distinctions among these entities, and they can be outlined as follows:

  • In general, smaller heat pumps typically require a one-phase electrical connection, while the bigger units utilize a three-phase power source.  The former is suitable for capacities of around 35kW.  Nevertheless, in the coming years, all heat pumps will be equipped with three-phase capabilities.

  • Heat pumps that operate on a single phase require 220 to 240 volts and rely on one live wire and another neutral wire.  Conversely, three-phase heat pumps operate on 380 to 415 volts and consist of three live wires and occasionally a neutral wire.

  • The final distinction between these two units lies in their intended markets - one is designed for the European market while the other caters to the UK market.


Choosing between a single-phase and three-phase heat pump for your HVAC system requires careful consideration of your specific needs, budget, and available electrical infrastructure.  While single-phase heat pumps are more cost-effective and easier to install, they may not be suitable for larger buildings or areas with high heating or cooling demands.  On the other hand, three-phase heat pumps offer higher power capacity, energy efficiency, and durability, but come with a higher price tag and installation challenges.
