  • Suitable for most detached houses (50-200 m²)
  • Power-adaptable outdoor unit – maximum power with minimum energy consumption
  • Significant energy savings
  • Environmentally friendly
  • State-of-the-art technology
  • Pleasant to use
  • Installation-friendly total delivery
  • Operating range down to -25 °C
  • The most efficient outdoor unit: Produces max. 65-degree water
  • MyUpway remote monitoring as standard

Heat according to the power demand of the house

Tehowatti Air Nordic system consists of two parts:

  1. The outdoor unit is a Monoblock air-to-water heat pump that takes energy from the outdoor air and transfers the heat thus obtained to the indoor unit via a compressor.
  2. Through the indoor unit, heat is distributed to the interior and hot water. The energy content of the outside air decreases as the air cools. If the heat pump does not provide enough energy from outside to meet the needs of the property, the heating element of the indoor unit will automatically assist the heating and provide the necessary additional heat.

How the system works

The heat output of the Monoblock outdoor unit of the air-to-water heat pump is automatically fine-tuned according to weather conditions and heat needs. This keeps the unit’s energy use as efficient as possible. Energy is taken from the outside air down to -25 ° C. At very low temperatures, the additional energy is obtained in stages by the heating element, which guarantees the minimum consumption of additional heat. As energy is taken from the outside air, ice accumulates in the outdoor unit during frostbite. Tehowatti Air is delivered with equipment that defrosts automatically if necessary. In all situations, the device takes care of defrosting the outdoor unit and draining the defrost water, ie condensate, into the sewer or drainage system of the house. This prevents ice from accumulating under or around the outdoor unit.

 

The indoor unit of the air-to-water heat pump distributes the heat produced by the pump and heats the heating circuit and hot water alternately. The indoor unit has an intelligent control system that adapts the operation of the pump to the heat demand of the house. The control logic continuously optimizes the air flow (speed-controlled fan), the cold circuit flow (electronic expansion valve) and the heat distribution circuit. In addition, the indoor unit has an electric heater that automatically takes care of heat adequacy even in the event of a frost. The indoor unit is only 1.8 meters high, but it has a built-in accumulator that can hold 215 liters of water, which is enough for even large needs.

 

The equipment delivery includes the equipment and components required for installation. These components (including automatic steering, expansion tank, circulating water pumps, buffer tank, changeover and safety valves) are factory-installed and tested. This speeds up the installation work and ensures the high quality of the system.
