The long expected low-structure forced-air heater ECO4 complements the ECO product family
Individually adjustable forced-air heating for each room is the best solution for low-energy and passive houses.
- Accurate individual heating adjustment for every room
- High thermal comfort
- Low heat losses in air ducts
- Simple, easy-to-use system
- Optimal energy efficiency
Building technology design for passive houses starts from minimising the need for heating and cooling. The system must be designed to meet the low overall heating power and energy consumption needs.
At best, the energy requirement for heating a passive house is no more than 20-30 kWh per gross square metre and 10-20 W per square metre for the rooms. The low overall heating power consumption requires that the heating system also works at low power and reacts quickly to changes. Externally purchased heating energy is needed only in the coldest periods. Room temperatures must be individually controllable to achieve high energy efficiency and thermal comfort. Outdoor air, cooler than indoor air, is mainly used for cooling.
The best heating method for a passive house is forced-air heating. In particularly high rooms, you can use a fireplace to provide additional heat. Forced-air heating gives the best individual temperature control for each room, which translates into high thermal comfort. When heating rooms individually, air flows do not need to be changed as heating needs vary because the supply air temperature will be automatically regulated in the terminal device according to the heating needs of each room.
The silent ECO series forced-air heaters work by preheating the supply air to approximately 15-17°C and then adjusting the heat to the requirements of each room individually. Heating is controlled by accurate relative control ensuring high thermal comfort. The higher the deviation from the preset temperature, the higher the heating power. When the room temperature is close to the preset value, the unit works at lower power. The control unit that houses the room temperature sensor has no heat-emitting components. This achieves a very accurate measurement of room temperature. The intelligent system reacts quickly to temperature changes and keeps the room temperature precisely at the desired level.
