4. Features
4.1 Safety
a. Realize isolation between water and electricity. No electric shock problem, more safety.
b. No fuel tubes and storage, no potential danger from oil leakage, fire, explosion etc. Five operating
mode:
1). Space cooling
2). Space heating
3). Water heating
4). Space cooling + water heating
5). Space heating + water heating
4.2 Environmental friendly.
a. R410a refrigerant;
b. No discharge of poisonous gas;
4.3 DC inverter system.
.
4.4 Automatic weekly anti-legionella function
4.5 Easy operation and automatic control.
The system can be controlled simply through the wire controller.

4.6 High efficiency and energy-saving.
The unit adopts heat pump principle, which absorbs heat from outdoor air and produce heat water, thermal
efficiency for water heating be up to 4.3.
4.7 All the weather the system can run.
Within the temperature range from -20 to 43℃, it will not be affected by night, overcast sky, rain and snow.
4.8 Convenient installation and maintenance
The quadrate type can be easily installed in a corner of the verandah even if it’s very narrow.
4.9 Total Heating Solution
When floor heating is conducted in a new house, warm air spreads gently across the house, making it
comfortable and enabling the use of broad space without necessitating radiators or FCU.
4.10 Comfort System
When floor heating is applied, warm air spreads gently across the house, making it comfortable. The system
can help blood circulation and metabolism, further boosting our health.
The installation of M-Thermal will eliminate oil or gas tank, making the household surrounding neat and safe,
enabling the use of more space, and avoiding refueling.
4.11 Reduce CO2emission
When the system is connected to solar panels, CO2 can be reduced more sharply.
In addition, M-thermal can significantly cut CO2 emission when being connected to solar thermal panel a
completely pure energy source.
4.12 CE approval
