  • Manuals & Installation

    Download the Technotherm TTB-E Duo WiFi Controlled Storage Heater manual here.

    Installation of storage heaters must always be undertaken by a professional electrician – this product is not suitable for DIY installation. The Technotherm Duo 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 Technotherm Duo 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.

  • What You Will Need

Technotherm's 2.55kW Duo storage heater makes economy 7 heating easier and more accessible than ever before. There’s no unintuitive dials or guesswork needed with the Duo: this smart storage heater is fully programmable so you can set precise comfort temperatures for every hour of the day throughout the week, leaving your heating to run itself. Even if you’re halfway across the world, you can still take full control of your heating by purchasing the Duo’s optional WiFi hub. This allows your storage heaters to connect to the internet so you can manage your heating on the move using a smartphone or tablet – simply download the app and enjoy innovative control at your fingertips. The Technotherm hub unlocks a range of extra features to help you slimline your running costs, including energy-usage statistics, guest account options and a geo-location feature which switches your heating to a lower level whenever you leave a set radius from your property.

Efficient heating technology

As well as offering smart control, the Technotherm TTB-E Duo also comes with smart heating technology for greater efficiency. It uses intelligent automatic charge, which calculates how much energy to draw based on your set program and the previous day’s usage, minimising waste without needing any user input. Each heating element inside the appliance can operate independently, so as it reaches its target charge, it can turn off each element in series to minimise the amount of power drawn from the wall. It’s a feature completely unique to Technotherm storage heaters and ensures your heating system is as affective as possible.

Another feature that is exclusive to the Technotherm range of storage heaters is its patented venting system. When more heat is needed, the vent opens to allow an extra flow of air to the bricks, and once opened, requires no more power. It’s completely automated, completely silent and doesn’t constantly draw energy – the perfect balance between manual venting and fan-assist models. In the event the Duo runs out of stored heat, you’re never left in the cold. Its in-built convection heater activates whenever you need a boost of warmth and always ensures your ideal comfort temperature is maintained.

High-quality German design

These German-engineered storage heaters are insulated for extra efficiency and use Ferolite bricks with a high iron content to provide optimal heat retention and conduction. Each unit is rigorously tested at every stage of the manufacturing process and is personally signed off by a quality control manager for traceability. Featuring a compact design with a modern chamfered body, the Technotherm TTB-E Duo night storage heater is the perfect upgrade to older manual models.
