Product Description

Please note that this product will be backordered for 15th August 2022.

The Mirrorstone 12kW Electric Combi Boiler For Domestic Heating & Hot Water is the perfect upgrade for most UK homes, offering a fantastic ratio of power to performance over older combustion boilers.

This boiler runs off of mains electricity, converting it into useful thermal energy. This is then sent throughout your home, just like in a traditional combustion boiler, sending heat through your radiators. It will also provide you with hot water, letting you enjoy a convenient all-in-one heating solution.

This boiler is equipped with modern anti-freezing technology. In simple terms, this means that if the water temperature drops below 8°C, the first level of anti-free will kick in, bringing the water temperature up to 15°C. If it drops further below 5°C, then the second level will activate, again warming the water to a safer level. This will help keep your boiler working effectively!

For a small extra fee, your boiler can come equipped with a WiFi-enabled thermostat. This handy device adds loads of extra features and convenience to your heating routine, and lets you take control of everything from your smartphone!

If you’re the sort of person who tends to panic that you’ve accidentally left the heating on all day, or who can’t stand getting out of bed to face a chilly house, this WiFI thermostat makes it easy for you to get things set exactly how you like them!

Please note that this Electric Boiler will require its own dedicated power line.

Eco Friendly Heating

One amazing benefit of using an electric boiler is that they can massively lower your carbon footprint in the right circumstances. This does come with a few caveats, which we’ll explain!

Firstly, electric boilers run entirely off of mains electricity. That means that they don’t burn any fuel on your property, which makes them theoretically carbon neutral. It also makes them a lot safer, as an added side benefit, with a much lower risk of leaks.

However, they still use power, and that power has to come from somewhere. However, every passing year, the UK reduces  its reliance on natural gas and other non-renewable and expensive sources of energy. So, by installing your boiler now, you can future proof your home for years to come.

Since this boiler operates off of electricity, you can also combine it with renewable sources of energy such as domestic solar panels. Thanks to their increased energy efficiency (electric boilers boast a near 100% efficiency rate in terms of converting the electrical energy they receive into useful thermal energy), this is a viable method of getting power, even in less sunny countries!

Even More Boilers

We have several other models of electric boiler available for you to purchase, so if this particular variant isn’t quite what you need for your home.

If you have another source of hot water on your property then you won’t need a combi boiler. In that case, consider the Mirrorstone 8kW Electric Boiler For Domestic Heating which is exclusively used for producing heat.

If you have a larger or less well-insulated property, then the Mirrorstone 14kW Electric Combi Boiler For Domestic Heating & Hot Water is a good option, using slightly more power to produce even more heat.

Installation Guide

Installation of an Electric Boiler should only be carried out by a qualified plumber.


Electric boilers are ideal for homes where there is no gas supply. Not only that, but they operate at far higher efficiency (99%) than most gas boilers (89-95%). Electric boilers also require no flue as there are no waste gases, and are more compact as a result. They operate silently and require no servicing.
