Inerzia Dry Stone electric radiators are easy-install, fully programmable electric heaters which provide an energy efficient heating solution for large and difficult to heat spaces — especially those with high ceilings.

Dry Stone Technology

The Inerzia Dry Stone range optimises the energy efficiency of large space heating with dry stone technology, a high-precision electronic thermostat, and fully programmable heating control. Lightweight ceramic dry stone elements inside the radiators heat up quickly and push out heat at greater intensity than conventional radiators, creating an energy-efficient means of heating large and difficult to heat spaces such as open plan offices, listed buildings, communal stairwells and rooms with high ceilings and large windows. The excellent heat retention properties of these ceramic dry stone blocks prevent the radiators working hard to maintain temperatures, with the potential to save energy and reduce heating bills. The precision thermostat is accurate to 0.2 °C, so the radiator will switch on or off automatically to maintain a comfortable temperature. With good insulation, this means the radiators only use power for a fraction of the time – creating massive energy saving potential.

Control Features

Fully programmable controls allow you to set a 7-day heating schedule to suit the usage of your rooms, with different settings for every hour of every day of the week. The Inerzia range is easy to control from the lockable control panel mounted on the face of the radiator. You can take your pick from 4 pre-set heating programs and 1 customisable heating program, and you can even control different rooms or areas of your house separately – keeping busy areas comfortable and preventing heat wastage in empty rooms.

These updated versions of the Inerzia for 2018 also feature adaptive start and open window detection functions, to improve efficiency and lower running costs. If a window is opened, Inerzia TTS radiators will sense the sudden drop in temperature and temporarily switch off until temperatures stabilise. This ensures you don’t waste energy if a window is left open accidentally. Meanwhile, the adaptive start function kicks in whenever the radiators’ temperature is scheduled to change. Rather than starting or stopping the heat at the scheduled time, these radiators will prepare in advance, learning how long it takes to raise the temperature and tapering its heating so it hits the desired temperature on time.

The Inerzia TTS range is mess-free, safe and easy to use. The control panel can be set to your choice of three languages (English, French and Spanish), and is fitted with an energy consumption meter which tracks how much power the unit uses every month. The radiators’ built-in memory can store your programming for up to 24 hours without a power connection – so you won’t need to worry about re-programming your radiators when there’s a power cut. All heating elements are fully enclosed so there's no danger of wall blackening.

The elegant contemporary design of these radiators makes them discreet yet stylish additions to any building. Lightweight and compact, Inerzia radiators are astonishingly powerful for their size. They're eco-friendly too: the 100% recyclable radiator body is made from high-grade recycled aluminium and comes with a 10 Year Manufacturer’s Warranty.
