SAUNIER DUVAL DUOTWIN CONDENSING 25-100 WITH ACCUMULATION 100 l COMPLETE WITH SMOKE KIT - NEW ERP Model: ErP efficiency class in heating/DHW: A Sanitary load profile: XL Type: Heating and domestic hot water Combustion chamber: sealed Domestic hot water production technology: Shift-Load Heating Nominal power P min/max heating 80/60 °C: kW 3.4/27 Partial load efficiency 30% 40/30 °C %: 108 Sanitary Rated power min/max (60 °C): kW 3/25 Specific flow rate (∆T=25 K): l/min 14.4 Continuous flow rate (∆T=30 K): l/min 24.4 Min/max DHW temperature: 35/65 °C Electrical characteristics Total absorbed electric power: W 105 Supply voltage/frequency: V/Hz 230/50 Dimensions: Dimensions (h x w x d): 1320 x 600 x 698 mm CNG code (G20) - 10014619 METHANE version DUOTWIN CONDENSING DuoTwin Condensing is extremely efficient from every point of view and, thanks to the "Shift-Load" system, guarantees a great availability of DHW. A 25 kW model is available with an integrated 100-litre boiler. Characteristics: Energy classification 4 stars ★★★★ (92/42/EEC) with efficiency up to 108%; Sanitary comfort 3 stars ★★★ (EN 13203-1), thanks to the "Shift-Load" technology for the production of stratified DHW, with high efficiency oversized sanitary exchanger with 20 stainless steel plates and 100 liter storage tank. Efficiency at 360°: thanks to the wide 1:8 modulation, the burner can modulate from 25 to 3 kw thus avoiding useless and inefficient On/Off cycles, keeping the efficiency values ​​constant over time at 108%. Even from an electrical point of view, consumption in stand-by is minimal: 2.3 Watts. The insulation of the boiler allows very low heat losses: 1.38 kwh/24h. Continuous domestic hot water production (DHW) up to 14.4 l/min (DT 25 K) Low NOx emissions - class 5 (EN 483) Total premix burner with high modulation and primary heat exchanger in anti-corrosion stainless steel High efficiency and modulating circulators (main and sanitary). antifreeze function Product Guarantee All products for sale on our site are new and packed. The warranty on this item is 24 months from the date of purchase.
