Installation of storage heaters must always be undertaken by a professional electrician – this product is not suitable for DIY installation. The Magma HHR is compatible with both single and dual supply systems. Wiring schemes for both options are provided in the manual.

Your electrician will select the appropriate wiring scheme for your property’s power supply and metering system. They should also assist you with ensuring you are on a suitable tariff, and that your charge periods have been set up correctly, for you to take advantage of off-peak electricity rates. Electric Radiators Direct cannot advise on energy providers or metering systems.

Please note – the flexible charge times and supply options available on the Magma HHR can also accommodate users who wish to power their heaters with self-generated energy such as solar PV or wind turbines.

The bricks will be supplied separately to the main body of the heater. Due to their weight, we highly advise moving them from the pallet in stages rather than all at once and recommend having another person on hand to help.

We do not recommend electric storage heaters for bathroom installation. This is because there is the temptation to hang towels over the appliance to dry, which can obstruct ventilation on the heater and cause a hazard.
Warranty

Ecostrad Magma HHR Storage Heaters come with a 10 Year Manufacturer’s Warranty on the heater body and 2 Year Warranty on the electronics.

Smart Heating Control with WiFi

The Magma can be controlled remotely through your smartphone when paired with its optional WiFi hub, giving you access to your heating from anywhere. The SmartHome Heating app allows you to manage 24/7 programming, track energy usage, and create guest accounts, all through a user-friendly interface. Plus, with its geolocation function, the Magma adjusts based on your proximity to home, making sure your space is always at the right temperature. If you prefer not to use WiFi, the Magma can also be programmed directly using the clear colour interface on the heater, giving you complete control at your fingertips.

Cutting-Edge Energy-Saving Technology

The Magma storage heater makes the most of Economy 7 and other off-peak tariffs with smart, efficient features designed to save energy. Its smart automatic charging adjusts based on your settings and previous usage, ensuring the heater only draws the necessary power. Each heating element is individually controlled, switching off when fully charged. This unique feature optimises efficiency and means you get the most out of every charge.

Silent, Efficient Venting System

A standout feature of the Magma is its exclusive silent venting system. When additional warmth is needed, the vent automatically opens to circulate air through the ceramic core, maintaining your set temperature without using extra power. Unlike fan-assisted models, this system doesn’t rely on constant electricity usage and operates quietly, providing efficient warmth without the noise. The Magma also features extra insulation to help retain heat for longer. If stored heat runs low, its integrated backup heater kicks in to keep the heat topped up.

German Engineering for Lasting Performance

The Magma is built with precision German engineering, so you’re guaranteed high standards of quality and efficiency. Each unit undergoes strict testing at every stage of production to guarantee reliability and performance. The Ferolite bricks inside the heater are known for their high iron content – they increase heat retention and improve conduction, further enhancing the efficiency of the Magma HHR. With its compact design and powerful performance, this storage heater is the ideal choice for modern, energy-conscious homes.
