Strom 6kW Single Phase Electric Heat Only Boiler - SBSP6H No Flue Compact Wall-Mounted Central Heating

Description

The Strom 6kW Single Phase Heat Only E-Boiler (model SBSP6H) is a compact, entry-level electric boiler built for central heating only, ideal for small homes, flats, extensions or annexes where a full-size system boiler isn't needed. It runs on a standard single-phase 230V domestic supply, needs no flue of any kind, and pairs with an indirect hot water cylinder if hot water is also required from the property.

At only 520 x 235 x 120mm, the SBSP6H is one of the smallest units in the Strom range, making it well suited to tight plant rooms, cupboards and utility spaces. With minimal moving parts for near-silent, low-maintenance operation, an LED digital display for simple control, and zero emissions at the point of use, it's a straightforward electric alternative for properties off the gas grid or where flueing a conventional boiler isn't practical.

Warranty*

Qualified Electrician Required

This boiler must be installed by a qualified, competent electrician registered with a competent persons scheme, in accordance with BS 7671 (IEE Wiring Regulations). An electrical installation certificate and a Part P certificate are legally required for any new boiler circuit, and this documentation is also a condition of the manufacturer's warranty.

Heat Only, Not Combi

This is a heating-only boiler: hot water must be provided separately, typically via an indirect hot water cylinder connected to the boiler's heating circuit. If instant combination hot water and heating from a single unit is needed, the Strom Combi Boiler range should be considered instead.

Correct Sizing Matters

A proper heat loss calculation should be carried out before purchase to confirm this 6kW output suits the property. As one of the smallest units in the range, it is best matched to small homes, flats, annexes or well-insulated new-build spaces with modest heating demand.

Ultra-Compact Wall-Mounted Design

At just 520 x 235 x 120mm, the SBSP6H is small enough to fit into tight cupboards, utility rooms and plant spaces where a full-size boiler wouldn't.

Minimal Moving Parts

With very few mechanical components, the boiler runs near-silently and needs little in the way of ongoing maintenance compared with fossil-fuel alternatives.

No Flue Required

As a fully electric boiler, the SBSP6H produces zero carbon monoxide at the point of use and needs no flue, chimney or external venting of any kind.

LED Digital Display

A clear LED display and simple control interface makes day-to-day operation straightforward for the end user.

Solar & Underfloor Heating Compatible

The boiler is compatible with solar panel systems and underfloor heating, giving flexibility for renewable integration or low-temperature heating circuits.

Space-Saving Plant Room Solution

Its small footprint and wall-mounted fitting make it a practical choice for extensions, annexes, and other spaces where every centimetre of plant room counts.

Does this boiler provide hot water as well as heating?

No. The SBSP6H is a heat only boiler for central heating. Hot water must be provided separately, typically by connecting an indirect hot water cylinder to the boiler's heating circuit.

Do I need a flue for this boiler?

No. As an all-electric boiler, the SBSP6H produces zero carbon monoxide at the point of use and requires no flue, chimney or external venting of any kind.

What size property is this boiler suitable for?

At 6kW, this is one of the smallest outputs in the Strom range, suiting small homes, flats, annexes or well-insulated new-build spaces. A heat loss calculation should confirm suitability for any specific property before purchase.

What size breaker and cable does this boiler need?

Strom's specification calls for a 26A rated current, a minimum 32A breaker and a minimum 2.5mm² cable. An electrician should always confirm the correct breaker and cable size on site, since supply voltage can vary property to property.

Can this boiler be paired with solar panels?

Yes, the boiler is compatible with solar panel systems, and can also be paired with underfloor heating circuits alongside standard radiator systems.

Is professional installation required?

Yes. Installation must be carried out by a qualified, competent electrician in line with BS 7671 wiring regulations, with an electrical installation certificate and Part P certificate provided as a condition of both building regulations compliance and the manufacturer's warranty.
