MaxiCondense 48 – 65 with 110% Efficiency Of course! MaxiCondense 48 – 65 Wall Mounted Condensing Boilers provide maximum heating comfort with their high efficiency for detached buildings.

Stainless Steel Heat Exchanger
The newly designed stainless steel heat exchanger has higher corrosion resistance. This provides a much longer lifespan. In addition, more condensation occurs with the stainless steel heat exchanger with increased thermal conductivity. More savings are achieved with increased efficiency.

A+ Seasonal Efficiency Values
It has 94% seasonal efficiency values and class A energy level. When used with the MiPro Sense Control Unit, it rises to A+ energy level and provides energy savings.

Rain Collecting Accessory
Rain or condensation water is collected by the collector and is driven to the device's siphon through a hose. It prevents any liquid from entering the boiler and prevents the electronic and metal parts from being affected by the liquid, thus ensuring Long-Lasting Use.
Hermetic Chimney Connection Possibility
It provides flexible installation opportunities thanks to the original hermetic chimneys that eliminate the need for ventilation in the boiler room.
Automatic Load Adjustment
The device automatically adjusts its capacity according to the needs of the space to be heated. It does not require manual adjustment. It provides energy saving because it works according to the capacity needs and does not work at high capacity.
Environmentally Friendly
It provides low flue gas temperature and low emission release, protecting the environment by burning the gas and air mixed in a perfect ratio in the most efficient way in the specially designed premix burner.
System without Bypass and Balance Tank
While the use of balance tank and system pump is mandatory in high capacity system installations, these system accessories are not needed thanks to the superior technology used in the new MaxiCondense 48-65 Wall Mounted Condensing Boilers. With the ability to connect the boiler directly to the system, both low cost installation and low return water temperature in the installation therefore savings are achieved.
High Capacity Opportunity
Thanks to the ability to cascade up to 7 devices with the MiPro Sense Control Panel, it is possible to control a capacity of up to 445.5 kW from a single device.
Control from the Control Panel on the Device
The boiler sensor and the system three-way valve can be controlled with the control panel on the device. No additional control panel is required.
High Energy Efficiency and Low Consumption
Thanks to the premix heat exchanger, it provides maximum efficiency of up to 109.5% and minimum heat loss.
Modulating High Efficiency Pump
Thanks to the high efficiency pump, the pump speed is automatically adjusted according to the installation needs. In this way, low electricity consumption is provided.
Dynamic Air Evacuation System
After the installation of the heating system, air is formed in the system. This reduces the operating performance of the system. With the dynamic discharge system used in MaxiCondense 48 – 65 Wall Type Condensing Boilers, air bubbles are not formed in the system. In this way, damage to the components inside the device is prevented and long-lasting use is provided.
Spouse Aging
Each unit operates in a cascade system with variable heat loads. When the first unit reaches a certain efficiency, the next module operates in a cascade system. High efficiency and long-lasting use are achieved by using each device for equal periods of time in the system.
Compact Dimensions
DemirDöküm MaxiCondense wall-mounted condensing boilers save space thanks to their ergonomic and compact dimensions and different side-by-side and back-to-back installation configurations.
