What is a wall-mounted pellet boiler?

A wall-mounted pellet boiler is a biomass generator that heats the water in your radiators and produces domestic hot water, burning pellets instead of gas. The wall-mounted version takes up little space and installs on the wall like an ordinary boiler, so you reclaim floor space while keeping standalone, independent heating. It is the ideal solution if you want to cut gas costs and rely on a renewable fuel.

How biomass heating works

The pellets burn in a combustion chamber and transfer their heat to the water in the system, which feeds radiators or radiant panels. Power is measured in kW and should be chosen based on the home's floor area and level of insulation. Unlike a pellet stove, which mainly heats the room it sits in, the wall-mounted boiler serves the entire hydraulic system of the home.

The hopper and automatic management

Every model includes a hopper that stores the pellets and feeds them automatically to the burner. Automatic management controls ignition, flame modulation, fuel loading and cleaning of the burn pot, so the appliance holds the set temperature without constant attention. Using a programmable thermostat or daily scheduling, you set the on times and let the boiler work on its own.

Efficiency and performance

Modern pellet boilers reach very high efficiency, because they recover most of the heat produced by combustion and lose very little. High efficiency means more heat with fewer pellets and therefore a lighter bill. Low emissions also allow many models to fall into the most virtuous environmental classes, a useful requirement for accessing incentives too.

The available brands

The catalogue features wall-mounted pellet boilers from the most reliable Italian manufacturers in the biomass sector: La Nordica and Kalor, with official warranty and readily available spare parts. Prices range from about 4.100 euros to over 6.600 euros, depending on the power in kW and the automatic management features. If you are looking for alternatives, you will also find wood stoves and the entire stoves and fireplaces section.

Tax incentives and grants

The purchase and installation of a biomass boiler may qualify for tax incentives where applicable, such as reduced VAT for renovation work, within energy efficiency upgrades. The conditions depend on the type of work and the appliance's environmental class, so it is worth checking the current requirements before buying and keeping the technical documentation.

Frequently asked questions

What is the difference between a pellet boiler and a pellet stove?
The wall-mounted pellet boiler heats the water in the system and feeds the radiators and domestic hot water of the whole home, while the pellet stove mainly heats the room where it is placed. The boiler is the right choice when you want to replace the home's main heat generator.
How many kW do you need to heat a home with a pellet boiler?
The power in kW depends on the floor area and the insulation of the home. As a rough guide you need about 1 kW for every 10 well-insulated square metres, but for correct sizing it is best to assess the home's actual heat loss.
How much pellet does the hopper hold and how often must it be filled?
The hopper capacity varies from model to model and determines the running time. With a large hopper and automatic combustion management, the boiler can run for more than a day on a single load, depending on the power demanded and the temperatures.
How does automatic management work?
An electronic system controls ignition, flame modulation, pellet feeding and cleaning of the burn pot, keeping the set temperature. With a programmable thermostat or daily scheduling you set the times and the boiler works on its own without constant attention.
Do pellet boilers have good efficiency?
Yes, current models reach high efficiency because they recover most of the combustion heat and lose little. High efficiency means using fewer pellets for the same heat produced, and therefore lower spending.
Can I use tax incentives for a pellet boiler?
In many cases yes. Biomass boilers may qualify for tax incentives where applicable, such as reduced VAT for renovation work, depending on the appliance's environmental class and the type of work. It is worth checking the current requirements and keeping all the documentation.
