Product Description

The SlimJim Electric Flow Boiler is a very compact floor-standing electric boiler designed and manufactured by the Electric Heating Company.

Why choose an electric boiler?

Electricity could be the best solution for home heating as gas and oil supplies begin to run low and are expected to run out within the next 40 years. There are many benefits to installing an electric boiler, including: zero emissions, no risk of a carbon monoxide leak, flexible installation as there’s no need for a flue, fewer moving parts to reduce the risk of a fault and no need for an annual service which are needed by law for gas and oil boilers.

Why is electric boiler efficiency different to gas?

Electric boilers often have an efficiency rating of 99-100% while gas an oil boilers tend to achieve a maximum efficiency of 93%. Despite this, electric boilers are awarded an ErP D-rating while gas and oil boilers have an A-rating.

During operation, electric boilers are highly efficient, converting almost all energy into heating and hot water for your home whereas gas and oil boilers produce waste. So, a 93% efficient boiler is wasting 7% of fuel efficiency rating which means that for every £1 spent on heating a home, 7p is wasted.

The reason for the lower ErP rating for electric boilers is because electricity is considered a carbon intensive fuel, producing double the amount of CO2 as natural gas, which in turn makes it much more expensive.

You can find more about this in our article Electric Boiler Efficiency Explained.

Could this boiler help to save me money?

A SlimJim electric boiler could save you money in a number of ways from the installation to lower energy bills. Electric boiler installation is much simpler than gas or oil boiler installations, potentially saving you over £250. Once installed, the 100% efficiency will keep your energy bills to a minimum and there’s no need to arrange an annual boiler service which is a possible saving of £60-£120.

How efficient is a SlimJim boiler?

SlimJim electric boilers are highly efficient, boasting a 100% efficiency rating and also have an ErP D-rating.

Is this electric boiler right for my home?

An output rating of 4 kW makes this SlimJim boiler best suited to smaller homes and flats with around 3-4 radiators.

Are there any alternative options in the range?

If 4kW is too small for your home, then the SlimJim electric boiler range includes many more options too: 7kW, 10kW, 12kW and 14.4kW.

What are the key features of the SlimJim electric boiler?

SlimJim electric boilers might be compact in size and minimalistic in design but there’s still plenty of room for features, which includes: virtually silent in operation, no mandatory maintenance, option of volt free or 230v control connections, a 6 stage heating, easy fit connectors and sensors, inbuilt fault finding diagnostics and an S-plan configuration which allows you to select heating only, hot water only or both at the same time.

The unit has an easy fit front cover for easy access on future maintenance, user-friendly front control panel, a unique run dry water level sensor that protects the heat exchanger from running dry in the event of system water loss, stainless steel heat exchanger that’s fully insulated to minimise energy heat loss, boiler temperature range that can be set between 30-80 degrees and there’s a unique high current safety cut-out device to protect the boiler from overheating.

How long is the warranty period?

SlimJim electric flow boilers are available with a 2 year warranty, with the option to upgrade to 3 years, so you’ll be well covered after the installation.

* This is a guide price for a straightforward, like-for-like boiler replacement. Installation costs will vary dependent on work required.
