Description
MPX... boilers are factory tested and delivered fully assembled.
They are delivered ready for operation with natural gas or liquefied gas.

MPX... MI Compact boilers are double-circuit boilers allowing to produce large quantities of hot water (★★★★★★ according to EN 13203) thanks to the enlarged plate heat exchanger.

High efficiency
- Efficiency at 30% capacity (50/30°C) up to 108.9%,
- NOx class: 6 according to EN 15502-1,
- Noise level: 48 to 53 dB(A),
- Low emissions (compliant with 2018 ErP directive):
- NOx ≤ 24 mg/kWh

Available optional equipment
- hydraulic connection kits (for water and gas),
- outdoor temperature sensor,
- expansion module for operation with two heating circuits,
- various room thermostats.

Advantages
-Stainless steel spiral central heat exchanger with composite cover with automatic venting function on commissioning;
- air-gas module with stainless steel gas burner with modulating output from 14 to 100% and adaptive combustion control (GCO);
- hydraulic module made of brass, equipped with: automatic bypass, heating / DHW switching valve, safety valve, pressure gauge, high-performance stainless steel plate heat exchanger for hot water preparation with micro storage (***according to EN 13203);
- 7-liter expansion tank;
- PWM controlled modulating fan;
- air-gas module for the preparation of a homogeneous mixture;
- mechanical pressure gauge under the boiler, for controlling the boiler filling and make-up;
- modulating heating pump (EEI < 0.23), which automatically adapts to the boiler specifications (maintains ΔT 20°C);
- simple and functional control panel with backlit screen, with indication of heating and DHW temperatures, with access to all boiler operation parameters and memory of error codes;
- condensate collector and condensate trap built into the boiler;
- possibility to limit the maximum output of the boiler depending on the thermal needs of the object;
- various room thermostats available as options: on/off switch, modulating thermostats and a thermostat for remote control of heating and DHW via a free app (available on Andriod and IOS).

Energy efficiency label
Each boiler is equipped with its own energy efficiency label, which includes various pieces of information: energy efficiency, annual energy consumption, manufacturer's name, noise level ...
If you combine your boiler, for example, with a solar system, with a DHW storage tank, or with another heat generator, you can improve the performance of your system and create a corresponding complementary "system" label: please follow the following link to the manufacturer's website "www.ecodesign.dedietrich-heating.com".
