Biasi Pro-Electric 14kW Single Phase Electric Combi Boiler
The Biasi Pro-Electric 14kW Single Phase Electric Combi Boiler (BIPROELEC14C) is a wall-mounted electric combi boiler that provides both central heating and on-demand hot water through your existing radiator pipework β with no flue, no gas supply, and no condensate drain required. It modulates from 2 kW to 14 kW, delivers up to 7 litres per minute of hot water, and operates at close to 100% efficiency since all electrical energy is converted directly to heat. Includes the Biasi Combi Fittings Pack (Ei1124500) β full-bore isolation valves, and automatic bypass valve β all required at commissioning and a condition of the warranty.

- Biasi Combi Fittings Pack (Ei1124500) β full-bore isolation valves (heating and DHW)
Features & Benefits
β No Flue β Install Anywhere
No combustion means no flue, no condensate drain, and no gas safety risk. The boiler can be sited in any room where the electrical supply can be run β kitchen, airing cupboard, utility room, or bathroom β without planning a flue route through the external wall.
β Direct Replacement for Gas Combi
The Pro-Electric uses the same ΒΎ" heating and Β½" DHW connection sizes as a conventional gas combi and fits straight into existing pipework and radiators. No system redesign is required β making it the lowest-disruption upgrade route when removing a gas boiler.
β 2β14 kW Power Modulation
Output steps down from 14 kW to as low as 2 kW to match actual demand rather than cycling on and off at full power. This reduces electricity consumption and eliminates the rapid cycling that shortens component life in non-modulating designs.
β 7 L/min DHW β Sufficient for One Bathroom
At the rated 7 litres per minute, the boiler raises incoming cold water temperature by up to 30Β°C β delivering a comfortable shower for a property with one bathroom or en-suite. At a reduced flow rate the temperature rise is higher, giving more flexibility at the tap.
β Underfloor Heating Compatible
A dedicated floor heating mode limits flow temperature to 60Β°C, protecting UFH manifolds and pipe circuits designed for lower operating temperatures. Switching between radiator mode (up to 80Β°C) and floor heating mode is done via the touchscreen display.
β Touchscreen Control Panel
The built-in touchscreen provides 24-period timer programming, winter/summer switching, child lock, and antifreeze protection. A room thermostat input accepts any standard 2-wire on/off demand signal β compatible with conventional wired thermostats and most smart thermostat systems with a wired relay output.
β Solar / Off-Peak Tariff Ready
An electric combi is the most compatible boiler type for use with solar PV and time-of-use tariffs (Octopus Go, Economy 7, Agile). Scheduling the boiler to run during cheap-rate or self-generated electricity periods is straightforward via the 24-period timer or an external smart thermostat.
β Fittings Pack Included β Warranty-Compliant
The Ei1124500 fittings pack contains every component required to meet the Biasi commissioning checklist: full-bore isolation valves and automatic bypass valve. Installing without these voids the warranty.

Frequently Asked Questions
Is the single-phase 14kW suitable for my property?
The 14kW single-phase version is best suited to flats, apartments, and 1β2 bedroom properties with one bathroom where the gas boiler being replaced was also in the 12β18kW range. It provides sufficient DHW flow (7 L/min) for one shower or bath at a time, and enough heating output for a well-insulated property with modern or recently replaced radiators. For larger properties or two-bathroom homes consider the 25kW three-phase version β but note this requires a three-phase supply.
What electrical work is needed before installation?
A dedicated circuit from the consumer unit using β₯10mmΒ² cable and a β₯80A MCB or ELCB is required β this is significantly larger than a typical 6mmΒ² cooker circuit. Many properties will need a new consumer unit or an upgraded incoming supply to accommodate this, particularly in older flats where the existing supply is rated below 80A. A Part P registered electrician must carry out this work and issue a certificate; Biasi will require this certificate for warranty registration.
Can it work with solar PV or a battery storage system?
Yes β an electric combi is well-suited to solar self-consumption. The 24-period internal timer can schedule heating and hot water during daylight generation windows, or an external smart thermostat (e.g. Drayton Wiser, Hive, Tado) can be wired to the room thermostat input for more dynamic control. For direct PV-to-heating diversion, a solar diverter device such as the myenergi eddi can be used in conjunction, further reducing the cost-per-kWh of operation.
What does the 7 L/min flow rate mean in practice?
At 7 litres per minute and a 30Β°C temperature rise, the boiler delivers water at approximately 50Β°C (assuming 20Β°C incoming cold mains). A comfortable mixer shower typically uses 8β12 litres per minute mixed down to 38β40Β°C β meaning the Pro-Electric can comfortably supply one shower outlet simultaneously. Running two showers at once, or a bath tap at full flow alongside a shower, will exceed the boiler's capacity and one outlet will experience a drop in temperature or flow. For multi-bathroom simultaneous demand, a stored hot water system (heat-only boiler with cylinder) is more appropriate.
