One of the names you’ll want to bear in mind if you are considering a new boiler is Ferroli. This company produces both commercial and domestic heating solutions, and it is well known for creating the Modena boiler. This is the smallest boiler of its known and it is also said to be the quietest. If your existing boiler habitually makes a lot of noise you will be pleased with this replacement. They also sell the Optimax and the DOMIcondens boilers, and all their offerings have a warranty on them that lasts for a minimum of two years.
The name of the company comes from Dante Ferroli, who created it back in 1955. As such it may not be the oldest company of its kind, but it has certainly achieved a lot in the half century or so since its beginnings in Italy. The vast majority of the components used to make Ferroli boilers are produced in their own premises, thus giving them the highest degree of control over the nature of each boiler they create.
You will not be surprised to learn that Ferroli has also created a selection of environmentally friendly boilers and products, thus developing its eco-friendly range too.
