The compact design of the SlimJim Electric Flow Boiler makes it ideal for heating applications where space is at a premium. The Slim Jim is a fully controllable Electric Boiler which is designed to maximise cupboard space.

Our single phase Electric Flow Boiler outputs are 4kW, 7kW, 10kW, 12kW with the 14.4kW available for properties that require larger outputs.

The SlimJim Boiler can be used in an ‘S’ Plan configuration to enable you to select Heating only, Hot Water only or both at the same time. It is 100% efficient, silent in operation and easy to install.

The SlimJim Electric Flow Boiler also has an easy-fit front cover for future maintenance purposes. It has a user-friendly front Control Panel incorporating an easy-to-use temperature control dial, heat and fault diagnostic indicators for the user and installer.

The unique Run-Dry Water Level Sensor incorporated within the SlimJim Boiler protects the heat exchanger from running dry due to system water loss. The Stainless Steel Heat Exchanger is fully insulated to minimise energy heatloss.

The Boiler temperature range can be set between 30 degrees and 80 degrees which also makes it a suitable choice for wet central heating radiators and underfloor heating systems.
Safety is of paramount importance and as such the Boiler incorporates a unique high current safety cut-out device to protect the Boiler against overheating.

The SlimJim can be supplied as a standalone unit or complete with a choice of Boiler Packs for Heating only or Heating and Domestic Hot Water Installations.
