LG Therma V R-32 green solution
The LG Therma V R32 monobloc heat pump system
The LG Therma V from Unitherm Heating Systems is an air to water heat pump (AWHP) that provides heating, cooling and hot water. As the indoor and outdoor unit are combined in one module, this monobloc system makes the transportation and installation much easier. There is no additional refrigerant piping required. Therma V is also very simple to set up and its uncomplicated layout and continuous operation-tracking make maintenance relatively quick and painless. It only takes the removal of three screws to access the water pump and strainer, while the data-logging feature makes it easy to check operation history and locate the source of any issues. Another key feature is the LG Therma V Configurator. This software allows the installer enter a range of project-specific information to get a clear picture of what needs to be done before arriving on site. It not only makes preparing for installation a straightforward matter, it also presents clients with an easy-to-understand
overview of the set-up process, letting them know what to expect. That said, installation flexibility and performance count for very little if the system cannot meet green energy targets. Therma V comes equipped with LG’s inverter technology which enhances energy efficiency without sacrificing operational capabilities. The inverter reduces energy consumption with its ability to vary output as needed, rather than simply being “on or off” like conventional setups. In addition, the Therma V’s BLDC fan motor offers greater energy savings – up to 40% at low speeds and 20% when running at higher speeds (compared to an AC motor). It also means reduced CO2 emissions.
Pre-installation setting – Based on site information, installers can prepare pre-setting with LG Heating Configurator and save data into a memory card in the office. At the site they simply insert the memory card at the back of the remote controller to activate configuration data.

A key strength of LG’s Therma V monobloc line-up is that all models feature the innovative, eco-friendly R32 refrigerant. The outstanding performance of these new units is also evidenced by a 4.45 Seasonal Coefficient of Performance (SCOP) in heating operation and an A+++ Energyrelated Product (ErP) label. The LATS (LG Air Conditioner Technical Solution) incorporated in Therma V can run detailed simulations that clearly illustrate its economic benefits, giving clients an accurate estimate of how much they can cut energy costs. Installers can specify a number of parameters, which the program then uses to calculate annual energy costs (compared to a conventional heating system); annual CO2 production; monthly energy usage and corresponding cost; and the total amount of thermal energy usage (in kWh) as the outside temperature changes over the course of the year. LG’s Therma V is designed to exceed everyone’s expectations, introducing simple installation and maintenance with ecofriendliness and superior energy efficiency. These strengths, coupled with the technical backup and experience Unitherm Heating Systems, makes for a formidable partnership and offers significant benefits for installers and end-users alike.
