Boiler Junkers Cerapur ZWBC 24-2C

The Junkers Cerapur ZWBC 24-2C is a mixed gas boiler condensation with microaccumulation and QuickTap system with a power of 24 kW to hot water and 22 kW to heating with energy efficiency class A for heating and hot water, and load profile M. Meets the new European standards ErP.

Junkers presents a complete range of heating solutions. Its new wall-hung boilers, adapted existing legislation and labeling efficiency (ErP), and systems of regulation and control, which are sure to find the solution to the needs and comfort of each home.

Maximum comfort in the smallest space Confidence and efficiency of hand

The new model of boiler Junkers, Cerapur, offers great comfort both heating and hot water with minimum dimensions. Your E Heatronic 3 allows a wide range of settings menus for the professional and the end user.

This endowed with microacumulación and accompanied the notice of demand QuickTap, model will get the most comfort in hot water, while a second tap is open during the shower. Comfort also quiet operation with only 35 dB (A).

The Cerapur model is very easy to install, since it is possible to place the boiler into two blocks: the first frame (11.5 kg) and then the boiler (28 kg), allowing a single professional perform the complete installation. The frame comes with the template included for easy assembly, reducing work to be done in the home.

The Cerapur with a yield of up to 93%, can also achieve an A + rating in combination with the controller MZ100 Junkers areas.

The thermal block of condensing boilers Junkers is unique!
Thermal silicon aluminum blocks of our condensing boilers have been, as always, fully developed and manufactured by Junkers. A high quality material with excellent technical features and performance compared to other made of stainless steel thermal blocks.

The density of aluminum is one third of the density of the stainless steel. This means that aluminum has a low thermal inertia, which allows you to react faster to load changes. Its thermal conductivity is - depending on the type of aluminum used - up to 14 times better than stainless steel, thereby generating high levels of efficiency. In addition, aluminum produced boilers are generally lighter and therefore easier to transport and install. Aluminum can production boiler more compact exchanger.

Easy Junkers, Wi-Fi (Optional)
Modulating Wi-Fi for remote control via mobile thermostat, to see the consumption of the installation at any time and place. Bus connected via two wires boiler. weekly and daily schedule, vacation mode, proximity sensor, compensation based on the outside temperature. Class VI according to ErP. 4% extra efficiency for the system. (Accessory not included)
