Manuals & Installation
Installation of storage heaters must always be undertaken by a professional electrician. They are not suitable for DIY fitting. 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.
You will need to input charge times for the storage heater via its menu so that it matches your tariff. This will also be the case if you are planning to use them with self-generated energy, e.g. solar PV or wind turbines.
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.
Technotherm TTB-E Duo WiFi Controlled Storage Heaters come with a 2 Year Manufacturer’s Warranty.

What You Will Need
The 3.4kW Technotherm Duo storage heater offers an economy 7 heating solution with unparalleled control. 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.
Take the guesswork out of home heating with the automatic charge function of the Technotherm TTB-E Duo. This function calculates how much charge is needed based on usage from the previous day and then automatically adjusts so that it has enough heat for the next day’s set program. This requires zero user input and delivers a much more intuitive and energy-efficient heating system for your home.
The Technotherm TTB-E Duo features three separate heating elements that can all operate independently of one another. This means that when the heater is reaching the end of its charging cycle, the elements will switch off one by one for more accurate charge and output, cutting down on the amount of power being used and preventing any wasted heat.
Instead of using energy constantly like fan-assisted storage heaters, the Technotherm TTB-E Duo comes with a unique venting system that allows air to easily flow through to the thermal bricks in a completely silent way. Once in place, this vent does not have to move again, using no energy whatsoever and provides a more energy-efficient heating solution.
When purchased with its compatible WiFi hub, the Technotherm TTB-E Duo allows for intuitive WiFi control. Simply download the Technotherm app onto your smartphone for easy heat management at your fingertips. Check the charge level and your power usage or simply adjust the temperature and control your heating no matter where you are in the world. As long as you have access to the internet, you’re always in charge of your home heating.
