Sime introduces the Murelle One HE 25 kW combi

Intelligent heating and hot water solutions provider, Sime Ltd is pleased to introduce the Murelle One HE 25 kW combination boiler.  Available from 1 May 2017, the Murelle One is Sime’s latest high-efficiency wall-hung 25 kW model, and is the most compact and energy-efficient boiler in Sime’s popular Murelle range.

Lightweight and easy to install, the Murelle One HE 25 kW features the elegance of Sime’s signature Italian design and is made from premium quality components including Giannoni’s new condensing evolution stainless steel and alloy heat exchanger, that incorporates larger diameter waterways.  Its compact size makes the Murelle One HE 25 ideally suited for rooms where space is at a premium.  This small but perfectly formed combination boiler packs a punch, delivering a 25 kW output to meet the on-demand heating and hot water requirements of any home.

Sime General Manager Massimo Bizzotto comments; “In many urban homes today, it is essential to maximise the use of space in every room.  The Murelle One’s compact size makes it perfect for smaller dwellings such as flats and houses with limited space.  While it may be small, the Murelle One doesn’t compromise on performance, delivering twenty-five kilowatts of power in the most energy efficient way possible.”

In addition to being operationally energy efficient, the Murelle One HE 25 kW is 100 percent recyclable, making it the ultimate environmentally conscious boiler purchase.
