Gas condensing boiler Altherma 3C D2CND024A1A 24 kW

Description

Wall mounted gas condensing boiler Daikin Altherma 3C D2CND024A1A 24 kW for Heating and Hot water

Engineered with innovative condensing technology to provide efficient and reliable heating and hot water.

Daikin’s gas condensing boilers are the best option for individuals planning to replace an existing boiler with a more energy efficient and cost-saving alternative. Daikin’s range of wall mounted boilers provide end users with the best in comfort, energy efficiency and reliability.

• Very compact unit and flexible in use: possible to install in nearly all room conditions (inside the house as well as outside) thanks to freeze protection for water piping
• Easy to service: all parts are accessible by only removing the front panel
• High heating efficiency up to 108%
• High modulating range 1:8 : the capacity is adapted based on the required heat load of the house from 3 to 24 kW
• Combine it with solar heating for even better energy efficiency.

Lambda Gx, automatic gas adaption system
The Lambda Gx control system creates the perfect combination of air and gas to attain high energy savings.

The system controls the amount of air and gas independently based on the flame quality (ionisation current).
Any fluctuation in the air and gas balance, (due to either outside air temperature or natural gas quality), can be detected by an ionisation current and electronically corrected.
To achieve an efficient combustion process, gas is gradually released into the mixture until the ideal ratio between gas and air is attained. This function extends the service life of the device and reduces the emission of harmful gases into the environment.

Premix Technology delivers high efficiency combustion by using a modulation fan to perfectly mix combustion air and fuel before it reaches the burner (air/gas mixer).

With the combustion of 1m3 natural gas, 1.7 kg of water vapour is released into the flue gas as latent heat. Instead of being disposed through the flue, the water vapour containing latent heat is recirculated and then reheated by a uniquely designed exchanger.

Condensation forms as a result of the water vapour being cooled to a temperature just below dew point, and then drained via a siphon. The condensing technology uses fuel efficiently to ensure high cost savings and sustainable operation with reduced emissions.
