HELIOTWIN CONDENSING

HelioTwin Condensing is extremely efficient from every point of view and thanks to the "Shift-Load" system it guarantees a very high availability of DHW.

A 25 kW model with integrated 200 liter boiler is available.

Characteristics :

• 4 star energy classification ★★★★(92/42/EEC) with efficiency up to 108%;
• 3-star sanitary comfort ★★★ (EN 13203-1), thanks to the "Shift-Load" technology for the instant production of stratified DHW, with a high-efficiency increased sanitary exchanger with 20 stainless steel plates and a 200-litre storage tank.
• Management of 1 forced solar circuit with integrated emptying: all the electronic and mechanical components for managing the solar circuit are integrated in the boiler for easy and efficient installation.
• 360° efficiency: thanks to the wide 1:8 modulation, the burner can modulate from 25 to 3 kW, thus avoiding useless and inefficient On/Off cycles while maintaining efficiency values ​​constant at 108%. Even from an electrical point of view, stand-by consumption is minimal: 4.4 Watts. The insulation of the boiler allows for decidedly low heat losses: 1.91 kwh/24h.
• Continuous domestic hot water (DHW) production up to 14.4 l/min (DT 25 K)
• Low NOx emissions - class 5 (EN 483)
• Integrated emptying solar system: designed for integration with emptying forced circulation solar collectors
• High modulation total premix burner and primary exchanger in anti-corrosion stainless steel
• High efficiency and modulating circulators (main, sanitary and solar).
• Antifreeze function
• Prepared for internal integration of accessories for multi-zone systems
