These units are floor-mounted water heating and storage systems designed specifically for applications requiring high-volume and continuous hot water, such as large detached houses, villas, or small-scale businesses. Thanks to their floor-standing configuration, they incorporate a large-capacity water tank (calorifier); they rapidly heat the water using natural gas or LPG and maintain the set temperature until the moment of use. The primary advantage over standard combi boilers is that instead of heating water instantaneously only when a tap is opened, they maintain an abundant supply of high-pressure, ready-to-use hot water within a large storage vessel.

Based on their technical design, they offer two different discharge and operating principles:

Room-Sealed (Hermetic) Models: These provide maximum safety by drawing the oxygen required for combustion from the outside via a dedicated fan and flue system and discharging exhaust gases back outdoors. They are the preferred choice for areas with limited ventilation.

Conventional Flue (Open Flue) Models: These draw combustion air from the room in which they are installed and discharge waste gases through a standard building chimney.

In summary, these systems are ideal high-capacity solutions for spaces where comfort is a priority and where multiple bathrooms or faucets must be used simultaneously without experiencing any drop in water temperature or flow.
