What is a built-in boiler?

The built-in boiler is designed to be installed out of sight, inside a recess cut into the wall or in a protected external housing. Unlike traditional wall-hung boilers, it stays hidden and leaves the wall clear and tidy. It is the ideal solution for anyone who wants to combine the comfort of heating with a refined look, without giving up performance.

The aesthetic and installation advantage

The main strength is the aesthetic advantage: the boiler disappears behind a door or panel, blending in with the furnishings and freeing up valuable space in the kitchen, bathroom or on the balcony. From an installation point of view, mounting it in a recess or outdoors makes it possible to use corners and spaces that would otherwise go unused, moving the appliance away from living areas and reducing its perceived bulk. A smart choice both in new builds and in renovations.

How to choose the output in kW

A boiler's output is measured in kW and is chosen based on the size of the home, the number of radiators and the demand for hot water. Here are some practical references:

  • Up to 24 kW: apartments and homes of limited size.
  • From 25 to 28 kW: average homes with good hot water demand.
  • Over 28 kW: large homes or those with many active draw-off points.

A properly sized output ensures constant comfort without wasted consumption.

Concealed, recessed or external installation

Built-in boilers can be installed in different configurations: concealed behind an internal door, in a recess cut into the masonry or in a dedicated external housing. The choice depends on the available space and the project. In every case the goal is the same: to achieve an efficient and barely visible system, perfectly integrated into its surroundings.

The best brands available

You'll find the leading manufacturers in the sector, with official warranty and available spare parts: Baxi, Riello, Savio, Ariston, Chaffoteaux and Beretta. Prices start at around 750 euros and reach the most complete solutions, for every budget.

Efficiency and condensing technology

Many built-in models use condensing technology, which recovers heat from the flue gases and clearly reduces gas consumption. To learn more about this technology you can browse the condensing boilers, while for more traditional installations the wall-hung boilers remain available. To complete your home's system, also consider the other heating solutions.
