Outdated Product
Compact and reliable gas boiler with touch control. Thanks to the condensing device, the model guarantees a 12-15% lower gas consumption, subject to standard heat transfer. The presence of the eBus communication interface provides the device with the ability to easily and quickly integrate with other heating sources, such as solar collectors, heat pumps, etc. You can optionally connect a wireless communication module. The Protherm Puma Condens 24/28 MKV-AS/1 gas boiler provides both heating and hot water. This is a complete two-circuit model, which is already ready for installation. The device received a circulation pump and an expansion tank. The heat carrier circulation pump operates on the principle of frequency regulation, which allows the heating circuit to heat up as quickly as possi...ble and to adjust the temperature regime with extreme precision. The boiler supports the possibility of installing weather-dependent automation. A room thermostat can also be connected. This model, among other things, is valued for its high efficiency, reaching 107.8%. The device will make it possible to significantly reduce gas consumption, while the savings will not affect heating. The boiler received protection against overheating, overpressure and freezing of the coolant.

Protherm, a member of the Vaillant Group, is known for its innovative solutions in the field of heating technology. The Puma Condens 24/28 MKV-AS/1 boiler is designed for heating large areas such as private homes or commercial buildings.

Economy and high productivity

This model range features a forced draft system and a closed combustion chamber. The main heat exchanger is made of aluminum and silicon alloy, and the additional one is made of stainless steel, which provides an efficiency of over 107%. The boiler is equipped with a built-in 8-liter expansion tank and an adjustable circulation pump.

Efficient hot water supply

The second circuit of the boiler provides water heating from 35 °C to 55 °C with a flow rate of more than 13 liters per minute. The quick start function allows you to get hot water almost instantly after opening the tap.

Intuitive control

The boiler is controlled via a touch panel with an information display, which also displays error codes. Thanks to the eBus interface, the boiler can be integrated with additional heat sources, such as solar collectors or heat pumps. The option of connecting a weather-dependent control system or a room thermostat is available.
