The Product

The Etna range is stunningly beautiful to look at and to touch. It can be manufactured in a range of sizes and power outputs to work perfectly in almost any room. There are two different colourways, White Etna and Black Etna. Both are finished in a satin finish and will never discolour, mark or deteriorate. Magma stone carries a lifetime warranty. If ever you have a complaint or concern regarding the Etna stone finish, don’t worry, any problems will be rectified by our technicians. If there is a problem with any Harmony stone, we never repair, we would always replace. Fortunately, problems with our stone heaters are very, very rare, but it’s good to know that we will be here to put things right if you have a problem. Etna is created to look and feel like natural stone, and it is manufactured in the same way as natural stone, heat and pressure. Etna is a luxury product, which is aesthetically pleasing and designed to blend in with your décor. The Etna range will not look out of place in any part of your home. It can become the centre piece in your lounge, become the focus of attention in your conservatory or be manufactured for the bathroom or shower room where we can design and install towel rails or towel hooks to keep your towels or bath robes warm and soft, whilst keeping your bathrooms free from mold and dampness. If we manufacture any Harmony product for use in a bathroom or wet room, we manufacture them as IP24 heaters, which comply with building regulations when installing electrical heating in any area where water is present. No matter where you need warm and controllable heating, the Harmony range will probably have a beautiful solution.

Etna is shaped and sculpted to reveal the undulations that you will only see in a natural stone product. It comes in a black or white finish and manufactured under 400kg/cm2 of pressure and then baked at 1200c. During the manufacturing process, the metal plates that shape the Etna stone finish, press the stone into the shapes that you see on the Etna finish.

In essence, the Harmony range, no matter what finish you choose, is the next step in modern electric heating and exclusive to the UK. With 100% efficiency and a choice of designs, perhaps it’s time for you to consider switching to an electric heating system for your home, that will not only make your home more beautiful, but will heat it beautifully as well.

Why Choose Magma Stone

The Magma Stone radiator is not dependent on water temperature or a boiler. It works at 100% efficiency. All the electricity used is turned into heat, so the money you spend is not wasted. It comes with its own thermostat, which is one of the most accurate available. Most thermostats are accurate to within 2c, but the Harmony thermostat is accurate to within 0.05c. For every 1c increase in temperature, your heating cost can increase by as much as 10%, therefore having a more accurate thermostat will reduce your energy consumption as the room never overheats.

As each radiator in the Harmony range works individually, there’s no need for pipework or disrupting installation. There’s no need for annual maintenance and your radiator should last a lifetime. You can say goodbye to unsightly rust and to cold spots in your rooms from ageing radiators.

What a difference it could make to your home.

The Magma Stone is designed in such a way to give comfort, ensuring you get the benefit of both radiant and convected heat with an even distribution in the room. Furthermore, you gain peace of mind knowing you have a wonderfully warm house, while significantly reducing your carbon footprint. And there’s very little effort from you to that effect. Plug it in, set your controls and enjoy the benefits.

Don’t forget, the design means it will also look fantastic in your home.

Heating Cruise Control (HACC)

The Harmony Cruise Control (HACC) uses minimal power consumption to maintain a constant temperature avoiding peaks and troughs of power usage and heat output. It is based on a predictive algorithm that adjust the consumption based on the thermostat readings (accuracy of 0,05ºC).

3 Level Temperature Selector

You can have total control over your heat output with 3 easy selections. Comfort, Eco and Frost. This gives you the ability to set your heating system up to ensure you’re using the correct amount of energy throughout the day.

Real Time Monitoring

The Magma Stone can combine with Wi-fi and wireless, which allows you to reduce energy consumption. It also means you can view your energy usage in real time. Hence you are totally in control of your costs and comfort. No big bill surprises at the end of each month.

Google Home and Alexa

The Climastar product range includes state of the art integration with the latest smart-home technology. So you can control your heating through voice activation. You can easily pair the apps with Climastar products.


Your Harmony heating system knows when you are home or away thanks to a Geolocator. So, if you have to leave unexpectedly, it will turn your heating down. When it ‘sees’ you coming home, it switches your heating to a higher setting.

Open Window Technology

With a Harmony product, you no longer need to worry about heat escaping from an open window or door. It will sense that the window is open and go into standby mode. Then, turn back on again when you close the window. Thus, you are not losing any heat and that saves you money.

How Does It Work

At the core of the technology with the Harmony range is the Magma Silicon Battery which stores heat which improves efficiency whilst reducing consumption. Twin Magma silicon batteries are key to keeping the room warm and comfortable whilst reducing energy consumption.

The front heat battery is designed to store heat and release that heat into the room for longer periods whilst drawing very little power. The front panel is manufactured with a ‘double core’ heat conduction chamber that optimises the convection process. The second Magma heat battery at the back of the heater absorbs heat that would have escaped into the back wall and transmits it back into the room, using all of the energy produced. No energy is wasted.

Furthermore, due to the way the front panel is manufactured, the heat is transferred in a uniformed way. Essentially, this provides the most efficient way to heat a room. In comparison, German designed heaters pass heat from an internal clay core, which then has to pass through a steel casing. Thus, a barrier is created which reduces the efficiency of the transference of heat into the room. Not so with the Magma Stone. Every Kilowatt of heat produced is passed into the room.

So the room stays warmer and the costs are reduced.

What Are The Benefits

With any Electric Heating System, you will benefit from a warm home while being kinder to the environment at the same time. With Harmony electric heating, there is 100% efficiency from your heating product, with no wastage. Because you are not burning fossil fuels, there are no pollutants released into the atmosphere. Additionally, there is no risk of a carbon monoxide leak in your home, as with gas. Or if using oil, there’s no risk of an environmental spillage.

Furthermore, you don’t need your fuel delivered to your door, and you don’t need to store it. Your Magma Stone radiator is hard wired into your electrical circuit. Using our award-winning wireless thermostat, you can set your temperature, set the times when you want your room to be heated and enjoy the control it gives you over your heating. The thermostat will “learn” your heating patterns and using an algorithm will work out when to draw power to heat the room to the exact temperature you have selected. Our thermostat’s keyboard is intuitive and very easy to use. Selecting the best temperature, or programing your heating to switch off or on, is simple and straightforward, just how you want it to be. Because our Thermostatic control units are wireless, they can be positioned where ever the customer wishes in the room, on the wall or as a free standing unit.
