Ariston boilers for heating and hot water

Boilers are the heart of the range. The condensing models recover the heat from flue gases and reduce consumption compared to older traditional boilers, providing heating and domestic hot water from a single unit. Output is measured in kW and is chosen based on the surface area to be heated and the number of radiators: the most common sizes range from around 24 kW for apartments up to 32 kW and above for larger homes. Most are wall-hung boilers, compact and simple to install.

Water heaters: from the classic electric model to the heat pump

Ariston is a benchmark for water heaters, available in many capacities to cover every need, from a single apartment to a large family. Alongside the traditional electric models you'll find heat pump water heaters, which produce hot water using far less energy and often qualify for tax incentives where applicable, such as reduced VAT for renovation work.

How to choose the right output in kW

For a boiler, sizing depends on the home and the system:

• 24 kW: medium-sized apartments with a limited number of radiators.
• 28 kW: homes with multiple hot water points and a good number of radiators.
• 32 kW and above: spacious homes or those with high domestic hot water demand.

For water heaters, the reference is instead the capacity in litres, to be matched to the number of people and the draw-off points. If you're unsure, our support team will help you choose the most suitable model.

Ariston air conditioners

Beyond heating, Ariston offers a range of wall-mounted monosplit air conditioners in the most requested sizes, from 9000 to 24000 BTU, with inverter heat pump technology to cool in summer and heat in winter. It's an appealing choice if you want to rely on a single brand for air conditioning and the thermal comfort of your whole home.

Tax incentives and reduced VAT

The purchase and installation of condensing boilers, heat pump water heaters and Ariston air conditioners may qualify for tax incentives where applicable, such as reduced VAT for renovation work. The conditions depend on the type of work, so it's worth checking the current requirements before purchase. You'll find discounted products in our offers section.
