Electric boilers provide many benefits to homeowners, not least the ability to become carbon free when used with a renewable energy supply.
With Government legislation banning the installation of gas boilers in new-build properties from 2025, the Biasi Pro-Electric range of boilers is the perfect alternative.
Seamlessly switch
Our electric boilers work in a very similar way to a traditional gas boiler, but can also be installed in properties where a gas boiler is not possible or where there is no gas supply to the property. It doesn’t need a flue, so can be sited anywhere.
It is easy to install, comes pre-wired and fits seamlessly into the existing pipework and radiator system. There are minimum moving parts, making our Pro-Electric boilers very quiet, offering low-cost servicing and less need for repairs.

Environmental advantages
he Biasi Pro-Electric boilers are almost 100% efficient, with power modulating from 2kw to full power, using less energy and therefore making the boiler cost-effective to run.
You can also make your heating carbon-neutral by:
- Integrating with solar PV panels
- Insulating the property well
- Choosing a 100% renewable electricity tariff
Clean power generation is a key part of the UK’s strategy to reach net zero by 2050 and the government is rgeting energy providers for all electricity to come from 100% zero-carbon generation by 2035.
The majority of domestic energy providers offer renewable energy contracts, although it is worth checking that the electricity is being generated from renewable sources and that there is no “greenwashing” taking place.

Benefits of the Biasi
Pro-Electric Boiler Range
- Almost 100% efficient and power modulates to use less energy
- Carbon-free with renewable energy tariff
- Very few moving parts, so almost silent, minimal repairs and low servicing costs
- Easy to install, no flue required and comes pre-wired
- No carbon monoxide, gas leaks or condensate
- Neat and compact design with stylish touchscreen control and digital display
Safety first
Because our boilers are electric, there is no risk of a gas leak or carbon monoxide.

We offer the option of a system boiler, which works in conjunction with an indirect hot water cylinder, or a combi boiler.
Our range covers different sizes and power levels, depending on the size of the property, the hot water requirements and the size of the electric supply into the property.

System BoilersSystem
Boilers
Our electric system boilers are a direct replacement for a gas boiler and are designed to work with an unvented indirect hot water system to provide all your hot water needs, especially in larger properties with more than one bathroom.
If you use a timer with the boiler, you can also set your system up to take advantage of off-peak electricity prices to heat your water.
The Pro-Electric system boiler works with both vented and unvented cylinders and can be integration with a olar PV system.
It has an integration pump and expansion vessel, stylish touchscreen control panel and minimal moving parts.

Biasi Pro-Electric
Combi Boilers
As with all the Pro-Electric boilers, our combi range can be sited anywhere in the property, as no flue is required.
This is a direct replacement for a gas combi boiler and uses the same pipework and radiators
It provides continuous hot water with flow rates of up to 7 litres per minute on the 14kw boiler, and has an integrated pump and expansion vessel
The single phase versions of the combi boiler are ideal for smaller properties, such as flats and apartments.
In larger properties with multiple bathrooms, we recommend the larger combi boiler that uses the three phase supply (or the system boiler with a cylinder)
