The Biasi Pro-Electric 14kW Single Phase Electric Combi Boiler (BIPROELEC14C) is a wall-mounted electric combi that supplies both central heating and instantaneous hot water from one compact unit, with no flue, no gas supply and no condensate drain. Because it uses the same ¾" heating and ½" hot water connection sizes as a conventional combi, it is a direct replacement that reuses your existing pipework and radiators.
Power modulates from 2kW up to the full 14kW so output follows demand, and hot water flow of up to 7 litres per minute on the 14kW model. It has an integrated pump and 5-litre expansion vessel, a touchscreen control panel with a 24-period timer, and a dedicated floor heating mode that limits flow temperature to 60°C for underfloor heating circuits.

Fittings Pack Sold Separately
The Biasi Combi Fittings Pack (Ei1124503) is not included with this boiler. It is available as an optional item so you can add it only when you need it.
Electrical Supply Check Before You Order
This model draws 61A at full load on a 230V single phase supply and Biasi recommend a 80A breaker with 10mm² cable. Biasi require a voltage and load test calculation to confirm the breaker size and that the property supply can carry the load before installation.
Best Suited to One Bathroom
Biasi's suitability chart rates the 14kW for radiators, taps and showers but not recommended for baths. For larger homes with multiple bathrooms, Biasi recommend the three-phase combi or a system boiler with a cylinder.
No Flue, Fit Anywhere
With no combustion there is no flue, no condensate and no carbon monoxide risk, so the boiler can be sited wherever the electrical supply can reach.
Direct Gas Combi Replacement
The same ¾" and ½" connections as a gas combi mean it fits existing pipework and radiators with minimal disruption.
2-14kW Modulation
Output steps down to 2kW to match demand, close to 100% efficient because all electrical input becomes heat.
Underfloor Heating Mode
Switch between radiator mode (30-80°C) and floor heating mode (30-60°C) from the touchscreen.
Touchscreen with 24-Period Timer
Includes winter and summer mode, child lock, anti-freeze and a room thermostat input for wired controls.
Integrated Pump and Expansion Vessel
A 5-litre expansion vessel, pressure gauge and safety valve are pre-fitted, and the boiler is supplied pre-wired.

Warranty and Installation Requirements
The 3-year Biasi warranty is only valid if the boiler is installed by a competent, registered installer, a Part P electrical certificate is issued immediately after the live connection, the guarantee is registered within 45 days of purchase, the appliance is serviced annually by a registered electrician, and a magnetic filter is fitted to the heating return. Biasi state they accept no responsibility for failures where these terms are not met.
Frequently Asked Questions
Is the fittings pack included?
No. The Biasi Combi Fittings Pack (Ei1124503) is sold separately as an optional item. Add it to your order if you need the fittings.
Is the 14kW single phase suitable for my property?
Biasi's datasheet positions single phase combis as ideal for smaller properties such as flats and apartments. It suits one bathroom; for multiple bathrooms Biasi recommend the three-phase combi or a system boiler with a cylinder.
What electrical supply does it need?
It draws 61A at full load and needs a 10mm² cable and an 80A breaker. Many properties will need a supply and consumer unit check first, and a Part P certificate must be issued.
Can I use it with underfloor heating?
Yes. Select floor heating mode on the touchscreen to limit the heating flow temperature to 60°C.
Can it be used with solar PV or off-peak tariffs?
Yes. The 24-period timer lets you schedule heating and hot water to run when generation or cheap-rate electricity is available.
