Sime VERA 25 HE condensing boiler Low NOx flue gas kit for LPG - New ErP Vera 25 HE model Heating energy efficiency class A Sanitary energy efficiency class A XL load profile Performance Nominal / minimum heat output (80-60°C) kW 19.8 / 3.8 Nominal heat input in heating kW 20 DHW nominal heat input kW 24 Useful efficiency 30% of the load (40-30°C) % 108.4 Heating sound power dB (A) 54 Electrical protection degree IP X5D Heating expansion vessel capacity l 9 Dimensions HxWxD 700x400x250 VERA HE THE BOILER FOR EVERY TYPE OF SYSTEM Vera HE is the range of premixed wall-mounted condensing boilers that adapt to different system solutions. Thanks to the high head of the circulator, it is perfect for managing radiant floor systems without the use of booster pumps. The compact dimensions make it suitable for replacing existing fixtures and for outdoor or recessed installation using simple accessories. Vera HE features a new single-tube primary exchanger in stainless steel which boasts larger water passage sections compared to market standards, thus offering low pressure drops to the hydraulic system. The single-tube geometry guarantees higher water speeds, preventing deposits and encrustations and furthermore facilitating the cleaning of the exchanger.
