Manuals & Installation

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.

Meet the Ecostrad Magma HHR High Heat Retention Storage Heater – a modern take on classic Economy 7 heating. With premium German engineering, smart energy management, and a design that saves you space, this storage heater keeps things simple while delivering highly efficient, EPC-ready warmth. No more fiddling with clunky dials or guessing how to get the best out of your heating – if you’re looking to upgrade your storage heaters, the Magma HHR is the right choice. The Magma's performance data has been made publicly available in the Product Characteristics Database, which can be accessed here.

Silent Heating with Exclusive Vent System

What makes the Magma HHR unique to the UK market is its silent venting system. Unlike fan-assisted models, the Magma HHR heats without noises or breezes. When more warmth is needed, the vents automatically open to circulate air through the ceramic core – and it doesn’t use up any extra power. Plus, if your stored heat ever runs low, the built-in convection heater can step in to give you an extra boost, so you're never left in the cold.

Smart Heating Technology

The Magma HHR makes sure you’re only using the energy you need thanks to its smart automatic charging that adjusts based on your settings and the previous day’s usage. Each element turns off individually when it’s fully charged, so you’re not wasting any energy. It’s this technology that fully optimises Economy 7 and Economy 10 tariffs – adaptable, efficient charging at night so you can fully benefit during the day.

German Engineering at Its Best

Thanks to its precise German manufacturing, the Magma HHR is packed with extra insulation and Ferolite bricks, helping it retain heat for longer so it can deliver reliable warmth throughout the day. As a testament to its quality, each unit is tested at every stage of production to make sure it meets the highest standards of efficiency and performance. Its 18.5cm profile and chamfered corners offer an ergonomic design with no sharp edges – allowing the Magma to more seamlessly blend into your living space.

Optional WiFi Control

Want more control over your heating? The optional WiFi SmartHub lets you manage everything from your phone or tablet, so you can adjust your heating from home or on the go. Compatible with the SmartControl Heating app, enjoy extra features such as energy usage statistics, geolocation, and smart speaker pairing.
