Premium Hybrid System 300L 日本語 AISI 304 + Solar Serpentine Δ COP 3,8 Leader
The heat pump DHW GIA-ATS-300SR290A of Giatsu represents the technological culmination in hybrid systems for sanitary hot water, combining the maximum capacity of 300 litres with stainless steel AISI 304 and integrated solar winding factory. With A+ energy rating in both climates and the leading POP of 3.8 (above the 200L model), this premium team offers up to 85% of energy savings by combining maximum efficiency aerothermics with free thermal energy, eliminating practically maintenance thanks to the natural R290 refrigerant electronic and revolutionary anode.
Designed for very large families of 5-6 people and light commercial applications looking for maximum capacity without compromising efficiency or sustainability, the GIA-ATS-300SR290A incorporates integrated solar winder of 10 meters with 1m2 of exchange surface and G 3/4" connections ready to connect thermal solar panels. Its stainless steel tank AISI 304 with a thickness of 1.5 mm and electronic anode ensures maximum durability without maintenance, while the R290 coolant with GWP of only 3 sets new sustainability standards in premium hybrid systems.
Optimized dimensions of Ø640×1850 mm and weight of 87 kg facilitate professional installation, while the ultra silent sound level of 41 dB and the Smart Grid Ready function allow perfect integration into modern homes and smart networks. With 8h:00min recovery time in warm weather, 1.55 kW reinforcement and automatic anti-legionela protection up to 70°C, this model represents the technological culmination for users seeking to combine maximum capacity (300L), leading energy efficiency (COP 3), absolute sustainability (R290 + solar) and maintenance-free durability in the most advanced hybrid system on the market.
Maximum efficiency of the entire range. Higher even to the 200L model. Perfect optimization great volume.
