Portable electric boiler range 19kW or 40kW

A portable electric boiler is a mobile boiler used for emergency heating, temporary heating, commissioning or testing heating systems or pipework and to reduce screed drying time on construction sites.

Our mobile electric boiler range includes a fully programmable digital control panel for staged heating and separate electrical sockets for use on a variety of different electrical power supplies.

Our temporary electric boilers come complete with an internal pump and expansion vessel, making them a system boiler on a mobile trolley with safety features such as overtemperature and high-pressure cutoff in a compact and efficient package.

These mobile boilers are suitable for providing heating on construction sites, at events, etc., they are also used as temporary heating in the event of central heating disruptions, such as boiler failure or maintenance downtime requirements in schools, healthcare centres, care homes, factories, or temporary buildings.

Emergency heating

These mobile or portable electric boilers are perfect for temporary heating, be it radiator or underfloor heating systems with rapid energy transfer / heat up times, in times of planned maintenance or a boiler heating system failure.

These trolley mounted boilers provide hot water to the central heating system with minimal disruption and can be installed quickly in various facilities, including care homes, hospitals, schools, domestic properties, and construction sites, provided they have the suitable electrical phase or electric generators available.

They are used in a variety of settings where temporary, supplemental, or emergency reliable heating is needed and where installing a permanent boiler system is impractical or unnecessary.

Underfloor heating system

Whether you’re proving or testing an underfloor heating system or using the underfloor heating to dry the screed out (screed drying of the floor), our range of portable electric heating boilers are the perfect solution for these tasks. Mobile electric boilers are compact, reliable, and 100% efficient, making them suitable for your site hot water system or your customers’ needs for providing hot water heating.

Our units have two standard screed drying programs that allow gradual rises in temperature over a period, which is essential when floor and screed drying is required.

These standard programs ensure compliance with EN 1264-4:2021, which is a set of guidelines for the installation of water-based, surface-embedded heating and cooling systems..

The standard includes requirements for leak testing and the initial commissioning and heating-up process of the system, such as with an underfloor heating scheme.

You can also set up your own specific heating programme if you have any special heating processes or requirements.

Speed up the drying process of screed

Our units have two standard screed drying programs that allow gradual rises in temperature, which is essential when floor and screed drying are required.

Key Advantages of Portable Electric Boilers:

• Clean operation: Electric boilers have no combustion, so no emissions or venting are required.
• Easy installation: Plug-and-play with minimal setup.
• Quiet and safe: No open flames or fuel handling with electric boilers.
• Precise temperature control: Ideal for temperature sensitive applications.
• Trolley mounted :Easy to manoeuvre and transport to site

Mobile electric boiler range

First, our 19kW portable electric boiler – this electric boiler can produce either 19kW, 11kW or 3kW (single phase only for 3kW output), depending on the electrical power supply, the 19kW and 11kW outputs require a three phase electrical supply. They are compact and durable electric boilers, self contained with a portable design on a wheeled trolley for ease of movement.
