Modern boiler with interesting features

The Italian double-circuit boiler Sime Brava Slim HE 25 corresponds to class A in terms of energy efficiency of heating and hot water supply. In addition to connecting to conventional radiators, it can be installed in underfloor heating systems. Thanks to the condensing principle of operation and "smart" control electronics, economical gas consumption is ensured in any mode. This boiler also has a function of pre-heating water ("hot start"), due to which it supplies hot water to the tap immediately after it is opened.

Although Sime is not the “coolest” brand on the heating equipment market, its equipment has exactly the same pumps, gas reducers and taps from well-known European suppliers as the “hardware” that are used by higher-class boiler manufacturers. Therefore, there are no problems with the reliability of the device. The stainless steel heat exchanger also contributes to a long service life, which is not afraid of the acidic environment characteristic of the interiors of condensing boilers. Residents of regions where gas is available only in cylinders will be interested to know that this unit is easily reconfigured to work on propane.

Compact device that is easy to hide in the kitchen

The word “Slim” in the title hints that this device is a “slim”. In width and height (700x400 mm), it is about the same as other boilers of the same class, but its depth is only 250 mm (5-7 cm less than average). Due to its compactness, this boiler, unlike more “pot-bellied” colleagues, can be easily built into a wall-mounted kitchen cabinet if you want to hide heating equipment that does not fit into the design of your kitchen.

Segment leader “up to a thousand euros”

Among the economical double-circuit boilers with the “warm floor” mode, Sime Brava Slim HE 25 is perhaps the most profitable option, because there are practically no other options with a price tag of around €1000. If you are not satisfied with its power (21.4 kW is enough to heat a house up to 171 m²), then in the same line of Sime boilers there are more powerful models: 25.7, 32.2 and 37.5 kilowatts (the last of them can serve objects up to 300 m²).
