Domusa DUAL CLIMA 6HTT ECPRO 6.0 kW Air-Source Heat Pump (230V) – R290
The Domusa DUAL CLIMA 6HTT EC PRO (230 V) is a 6.0 kW high-temperature air-to-water heat pump developed by Domusa Teknik. Designed with a compact monobloc structure, this outdoor unit houses the entire refrigeration circuit, eliminating the need for refrigerant gas handling during installation. Natural refrigerant R290 (Propane): Uses an ultra-eco-friendly gas with a Global Warming Potential (GWP) of only 3, minimizing the carbon footprint and improving overall energy efficiency.
High temperature (up to 75°C): Capable of generating a water flow temperature of up to 75°C. This makes it an excellent solution for energy renovation projects (as a direct replacement for a fossil-fuel boiler) without requiring the replacement of existing conventional radiators. Single-phase power supply (230 V): Ideal for standard residential setups. High energy efficiency: Rated up to A+++, with a Seasonal Coefficient of Performance (SCOP) of up to 6.4, depending on installation conditions.
EC PRO Technology: Features a high-efficiency electronic circulator (EC) that automatically adjusts flow rates based on the home's actual needs, drastically reducing electricity consumption. Versatility (3-in-1): Provides heating in winter, cooling in summer, and domestic hot water (DHW) production. It allows domestic hot water to be heated up to 70°C without the need for electric backup for Legionella protection.
