Ferroli SEV50 50 Litre 3kW Unvented Electric Water Heater c/w G3 Expansion Kit GRDR4W0A
The Ferroli SEV 50 is a 50-litre vertical unvented electric water heater supplied complete with a G3 expansion kit — everything needed for a fully Building Regulations G3 compliant installation, straight from the box. Built with a titanium-healthy blue silicone glass-lined inner vessel and a stainless steel heating element rated to 3 kW at 240 V, the SEV50 delivers reliable hot water storage for studios, small flats, and single-occupant all-electric homes. With an IPX4 splash-proof rating and shockproof ABS casing, it suits bathroom and utility-room installations alike.
Unvented hot water systems must be installed and commissioned by a G3 accredited competent person in accordance with Building Regulations Approved Document G3 (England & Wales) or equivalent Scottish / Northern Irish regulations. All electrical connections must be made by a qualified electrician in line with current IET Wiring Regulations. The Benchmark commissioning checklist must be completed and left with the householder.
The SEV50 is heated entirely by its 3 kW electric element. There is no boiler coil — this is an ideal solution for all-electric properties, flats without gas supply, or Economy 7 installations. The complete G3 expansion kit is included; no separate unvented components need to be sourced.
The inner tank is finished with Ferroli's titanium-healthy blue silicone glass lining, which inhibits limescale build-up, improves energy efficiency, and extends vessel lifespan compared to bare-steel alternatives. The stainless steel heating element is independently warranted for 3 years, providing peace of mind in both soft and hard water areas.
Supplied as a fully compliant G3 package — the expansion kit, safety controls, and all required unvented components ship with the unit. No additional unvented kit purchase is required, making this a cost-effective and convenient specification for G3 installers working on new or replacement installations.
IPX4 splash-proof protection makes the SEV50 suitable for installation in bathrooms, shower rooms, and utility areas subject to water spray, compliant with current IET Wiring Regulations zone requirements. The shockproof ABS outer casing protects internal components in demanding installation environments.
A user-adjustable thermostat allows output temperature to be set to preference. The vertical wall-mounted design allows easy access for periodic servicing without the need for major disassembly. A built-in electrical cable is pre-fitted for straightforward connection to a dedicated fused spur.
As an unvented cylinder connected directly to the cold-water mains, the SEV50 delivers hot water at mains pressure — no loft tank, no pump required. This ensures consistent flow and pressure to all hot outlets in the property, and is compatible with thermostatic shower valves that require balanced hot and cold pressures.
Ferroli has designed and manufactured water heating appliances since 1955 in Verona, Italy, and now operates in 14 countries. The UK operation is based in Burton-upon-Trent, Staffordshire. Ferroli's water heater range covers instantaneous and storage units from 5 L to large commercial capacities, with a strong focus on build quality and long service life.
