Batteries, "warm floor" and hot water in the tap

The wall-mounted boiler BAXI LUNA Duo-tec 24 is suitable for heating houses or apartments up to 174 m², as well as heating water for east european needs. Like other condensing type devices, it has a high efficiency (107.6%), which ensures economical operation (gas consumption in full load mode does not exceed 2.61 m³ / h). Due to the continuous electronic modulation of the burner, the device has a wide operating temperature range (25 – 80 °C). Therefore this copper can work in the low-temperature mode necessary for heating systems like "heat-insulated floor".

Flexible settings

In terms of the flexibility of settings, BAXI boilers of the LUNA Duo-tec series can give odds to equipment from other manufacturers. They, for example, have built-in automation with a room thermostat (so you won't need to buy additional accessories and sensors for a fee to auto-adjust the temperature in your house). In addition, on-board electronics allows you to control multi-temperature zone systems.

"Old-timer", trustworthy

We can say about the BAXI LUNA Duo-tec 24 device that it is a time-tested technique (it has been produced for almost 10 years). This model is well known to service engineers (like many other boilers, BAXI heating equipment needs annual scheduled maintenance to maintain the warranty) and does not cause problems for users. The boiler is well adapted to east european realities. It can work even at low gas pressure in the pipe (down to 5 mbar, which is about two to three times less than normal pressure). It can also be converted to propane if you use bottled gas.
