Overview:

 

Hermann Saunier Duval presents Master Condens in a brand-new version with an elegant, revamped design, always top efficiency (etas to 94%) and always with a focus on the customer's sanitary comfort that is enhanced with the new Smart Tank Loading function.


 

This new function minimizes burner ignitions through intelligent management of hot water recharging of the two tanks only when needed. All this is possible through careful analysis of the boiler electronics in the first weeks of use.

 

The electronics follow the user step-by-step, recording personal sanitary demand times/habits thus enabling the boiler to always provide the best possible experience and maximum comfort whenever required.

 

The new Master Condens range boasts exceptionally low consumption and ranks at the top of its class in terms of both sanitary comfort and efficiency, thanks in part to the exclusive Aquaspeed PLUS ® system for domestic hot water production, which allows for stable temperatures even with large simultaneous drawdowns for comfort at the highest level.

 

In addition to the external look, Master Condens is also totally renewed in the heart of the boiler thanks to the new FlameFit combustion system that allows self-adaptation to the different supply gases in Italy and allows the boiler to be used with a gas mixture containing up to 20 percent hydrogen.

 

Combined with the ADA technology of balancing feed gas pressures, it provides the most correct air/gas mix needed in order to achieve the best possible combustion. Guaranteed modulation values can cover values up to 1:10. These new product features, in parallel with an evolution of the electronics, allow the boiler to fully adapt to the actual demands of the heating system, also allowing a reduction in gas and electricity consumption.

 

• 4-star energy rating (92/42/EEC) with efficiencies up to 109.5%;3-star sanitary comfort (EN 13203-1), thanks to the exclusive Aquaspeed PLUS® technology with stainless steel plate sanitary exchanger and double dynamic storage tank (42 liters)
• Solar Easy. All models in the Master Condens range are compatible with all solar systems. If the solar irradiation is not sufficient to maintain the domestic water at the desired temperature, the boiler intervenes to supplement it.
• Master Condens is compatible with the MiGo WiFi control unit. The wall-mounted boiler is ready to be managed remotely simply with your smartphone.
  
   

New touch-screen user interface:

• New "talking messages" make it easier to manage the operating menu and allow easier interaction between the boiler and the user.
