THEMAFAST Condens 30-B (H-ES) Saunier Duval boiler

The START &, HOT MICROFAST 2.0 microaccumulation allows combination boilers to notably improve their performance in hot water as well as significant savings in water and gas. Thanks to this technology, the user enjoys excellent sanitary comfort, much higher than that provided by an instantaneous boiler but with the same size. The system is based on a 3-liter tank, in which, due to the arrangement and design of two tubes that it houses inside, the hot water enters immediately mixing with the one that is already deposited, avoiding stratification. It has an anti-water hammer system, which, incorporated into the micro-accumulator, manages to effectively reduce the pressure increases that occur when closing, especially the mixer taps. It has static isolation and dynamic isolation, which consists of a small electrical resistance.

Comfort and silence
Ergonomic and easy to use. Large displays and “one button - one function” panels make regulation a very simple maneuver with temperature stability as the first objective. We select all the components in order to optimize the sound level. The “single box” structure reduces thermal losses, makes maintenance easier and makes Saunier Duval boilers incomparable in terms of silent operation. A constant temperature in the home, whatever the outdoor environment, thanks to optional elements such as the outdoor solar probe with which variations in the outdoor temperature are taken into account immediately by the boiler before they have an impact on the home. or the wireless programmer-thermostat control that controls the boiler continuously to provide the desired temperature.

Performance and high modulation
Instantaneous performance levels up to 109% and impressively high modulation ranges. The boiler regulates its power from very low demands to the highest, always consuming just enough energy, avoiding stop-start. Intelligent modulation of the power controls the temperature of the heating water resulting in the maximum operating efficiency of the boilers.
