LG THERMA V Air to Water Heat Pump Systems
What is Therma-V?
Therma-V provides an economical, environmentally friendly solution to central heating. It works on the heat pump principle. The outdoor unit removes heat from the air outside and transfers it to the indoor unit, where it is used to generate hot water. This hot water can then be used for under-floor heating, radiators and in a hot water tank.
Up to 4.5 kW of heat can be produced for every kW of electricity consumed. The amount of kW of heating provided per kW of electricity is called the Coefficient of Performance, or COP
Indoor unit models are
HU091 U41,- 9 Kw capacity
HU121 U31 – 12 Kw capacity
HU141 U31 – 14 Kw capacity
HU161 U31- 16 Kw capacity
The indoor unit (Hydro) works in the same way as a Conventional central heating boiler, except that it uses heat recovered from the outdoor air instead of gas or oil. Hydro Unit Outdoor unit
Optimum efficiencies are obtained at low water temperatures, so the system is ideally suited for under-floor heating.
Hot water supply
Therma-V is designed to provide hot water, in addition to central heating in domestic applications.
Therma-V can heat the water in the tank to 48 °C without using electric heaters. There is provision to program an automatic weekly sterilisation process at a higher temperature, using electric heating.
It is possible to combine Therma V with solar heating, taking advantage of free heating when it is available. A tank with twin coils is used in this process.
The LG tank kit (Part no: PHLTA) is required when a hot water tank is fitted. It includes a thermistor to monitor and control the hot water temperature.
A suitable water tank should have the following features:
● Be designed for heat pump applications, meaning that the internal coil should have sufficient surface area to heat the tank using water at 55°C.
● A twin coil tank is required if solar heating is added.
● The tank should have an immersion heater with a variable thermostat (in addition to the safety cut-out).
- There should be a suitable pocket to insert the LG thermistor.
● The LG tank kit is used to measure and control the tank water temperature.
