SlimJim Boiler & Direct Cylinder Packages

Boiler output range from 7kW to 14.4kW and Cylinder capacities from 120L to 180L

SlimJim Electric Boiler & Cylinder Heatpacks are designed to reduce installation time and eliminate unnecessary external plumbing and pipe work. This value-for-money package includes a 7kW SlimJim Electric Boiler and a 120L Direct Stainless Steel Cylinder complete with a Boiler Pack designed for Heating and Domestic Hot Water installations.

SlimJim Electric Boiler Packages are available with single phase Boilers from 7kW to 14.4kW with a choice of Direct Stainless Steel Cylinders from 120L to 180L. An Electric Boiler on a wet central heating system presents all the controllability offered by a gas fired central heating system. Using standard pipe-work, conventional wet system radiators and thermostatic radiator valves the boiler, being 100% efficient and fully modulating, will take the same amount of time to heat the property as a gas boiler. As no flue is involved and no gas analysis is required the installation of the system will be a lot quicker than that of a gas system boiler.

Our single phase Electric Flow Boiler outputs are 7kW, 10kW, I2kW with the I4.4kW available for properties that require larger outputs.
