3 Phase electric boilers – 0.8kW to 5mW

3 phase electric boilers are commonly used and installed for a central heating system and hot water (domestic hot water via a indirect hot water cylinder for high flow rates) production in locations such as large properties, guest houses, and hotels with a suitable 3 phase electric supply to the building.

Our three phase electric boilers have been specifically designed to meet the heating demands of large domestic properties and commercial buildings or spaces.

Installation can be almost anywhere in the property, as no flue or external wall is needed with a 3 phase electric boiler. Thus making the boiler easy and quick to be installed.

They are highly efficient (100% on the immersion heaters) and have high heat load matching or modulation rates, which modulates the electricity consumption and also reduces the running costs of the wet electric heating system.

Using green or renewable electricity as a heat source for the electric boiler, can ensure a carbon free central heating system.

Three phase boiler product options

FHMN3-8  This 8kW 3 phase electric system boiler,with pump and 5 litre expansion vessel,has PV solar readiness with an adjustable output range of 2kW, 4kW, 6kW, and 8kW, and a 400V 3 phase electricity power supply is required.

 

This 3 phase electric boiler modulates to the following power output steps: 

0.8kW, 0.9kW, 0.9kW, 1.3kW, 2kW, 2.6kW, 3.3kW, 4kW, 4.6kW, 5.3kW, 6kW, 6.6kW, 7.3kW, 7.9kW

So yes, this electric boiler can be set to either 2kW, 4kW, 6kW or 8kW (technically 7.9kW, but close enough to 8kW for us), and the boiler will ramp up and down the above modulation scale depending on what the heating system demands.

FHMN3-24 A 24 kW 3 phase electric system boiler with pump and 5 litre expansion vessel,, PV solar ready – 400 Volt 3 phase electricity powered.

This 24 kW 3 phase electric boiler modulates to the following power output steps: 

1kW, 2kW, 4kW, 6kW, 8kW, 10kW, 12kW, 14kW, 16kW, 18kW, 20kW, 22kW, 24kW

This 3 phase electric boiler can be set to either 12 kW, 16 kW, 20 kW, or 24 kW and will ramp up and down the above modulation scale depending on what the heating system demands.

We go all the way up to 45kW in output this domestic range of 3 phase electric boilers, and are fully detailed on this webpage – electric central heating boilers.

28kW to 96kW Output electric boilers

Our commercial 3 phase electric boilers, which are available from 28 kW to 96 kW in outputs, with stainless steel heating elements and 7 power-step output modulation for central heating only or central heating and hot water.

These electric boilers benefit from full BMS (building management system) or 0-10 volt control capabilities (commercial installations often require this control regime) with our standard “X” control panel. This range of three phase electric boilers can be wall-mounted or floor-mounted with our floor-mounting kit.

Three phase electric supply

Three phase systems are better suited for high-demand scenarios because they can deliver significantly more power than single-phase systems.

Three phase electric boilers deliver power more consistently compared to single-phase systems that use one alternating current wave.

Three phase electric boilers provide better load balancing by spreading the electrical load across three wires.

Three phase electric boilers use three live wires, each 120° out of sync, for more powerful heat delivery, making them ideal for large demands.

Only qualified individuals should handle electric installation of the unit to comply with safety standards and local electrical codes. A plumber or electric heating company or a combination of both can fit our three phase electric boilers with easy.
