High Efficiency Combi Boilers
The new Basica boiler completes the Biasi condensing pre-mixed range of boilers.
Compact yet powerful, the Basica is a reliable boiler that guarantees high efficiency, low consumption and respect for the environment.
This boiler comes with built in weather compensation, by installing a simple inexpensive temperature probe (optional), it will allow the boiler to automatically react to what is happening with the outside temperature, giving you that boost when you need it and saving you money when you don’t.
Biasi have removed the plastic blocks from the boiler and replaced them with a fully brass hydraulic valve section. The Condensing Heat Exchange is stainless steel with an aluminium coating to offer maximum resistance to corrosion.
The Basica is the perfect choice for someone looking for ease of operation. At the same time, you also have the ability to add an array of advanced optional controls that will improve the comfort of your home and reduce your heating bills.
The Basica range is available in 24kw, 28kw and 32kw.
The Basica range comes with a full 5 years guarantee covering parts and labour*
