The Ecowec® R8 is designed for renovation targets with narrow pathways. It is suitable for larger townhouses and apartment buildings where the water consumption exceeds 3,000 m³ annually. The integrated exchanger in the unit allows for preheating of domestic water, utilization of solar heat, or cooling of ventilation. R-sarjan tuotteet voidaan kytkeä kaikkiin lämpöpumppujärjestelmiin.
A value-added tax of 24% is added to the price.
The Ecowec® R3 is designed for townhouses and small apartment buildings where the water consumption exceeds 1,000 m³ annually. The integrated exchanger in the unit allows for preheating of domestic water, utilization of solar heat, or cooling of ventilation.
Recommendation: 1 unit of Ecowec R3 for 20-30 apartments or 3,000 m³/year – additional Ecowec R3 units if the building has more apartments or if there’s greater water consumption.
Connection Recommendation: Requires pressurized wastewater guidance to the exchanger using a wastewater pumping station, and connection to the heat pump. Heat recovery can be enhanced by connecting multiple hybrid exchangers in series and/or in parallel within the same system.
Flow Rates: Maximum flow rate for the wastewater side: 30 l/s, maximum flow rate for the heat collection side: 20 l/s, maximum temperature for flowing liquids: 80°C.
Dimensions: Width 550 mm, Height 1550 – 1650 mm, Weight 200 kg (empty), 500 kg (in use).
Pressure Class: PN4
Wastewater heat recovery is the most cost-effective way to reduce the property’s energy consumption. About 30% of the residential building’s annual heating energy consumption goes to heating the domestic water and thereby to the sewer. In energy-efficient class A properties, the share of energy contained in domestic water is more than 50% of the heat balance. It is possible to recover thermal energy from waste water sent to the sewer and use it again with the help of the Ecowec hybrid exchanger.
