Recuperators with electric heater

Electric afterheater

— air ventilation units with such heating are easier to install and maintain than water ones, but they have high energy consumption, especially if the overall performance of the unit is also high. The power of the heater is usually an order of magnitude higher than the flow (for example, about 25 kW at a capacity of 2500 m³/h), and all these kilowatts must be taken from the mains. As a result, electric heaters significantly affect the amount of electricity bills. However, simplicity and convenience have led to the fact that this particular type is the most common today.
