Characteristics

Models: 24, 28, 1.24
Compact dimensions (700x395x285) and light weight (28,5 kg)
Central flue (as traditional boilers), for easy and fast replacement
1:5 modulation to match the thermal output of the boiler to the demand of the building, optimising comfort levels. Reduced stress on components, lower noise level, and increased reliability
Stainless steal heat exchanger with large water passageway, greater thermal seasonal efficiency
New hydroblock reduces electrical consumption, and maximises DHW flow rate
Remote control Baxi Mago as optional

Features

Baxi Space

Advanced system control for a smart integration of different technologies. It offers a customized and efficient system tailored to meet all your needs and preferences

Digital Ready

It can be connected to BaxiMAGO, the WI-FI smart modulating thermostat, and Baxi service App. You can have your boiler always under control

Hydrogen Ready

Ready to work with a 20% hydrogen/natural gas blend, reducing gas consumption and environmental impact

Hybrid Ready

It facilitates the integration of other heating sources, simplifying the climate management of your home

1:5 Modulation

Modulation up to 1:5 reduces on-off cycles for improved efficiency and savings

(1) Low temperature: return temperature (at boiler inlet) for condensing boilers 30°C, for low temperature boilers 37°C and for other heaters 50°C.
(2) High temperature setting means 60 °C return temperature at boiler inlet and 80 °C flow temperature at boiler outlet.
