Haverland Inerzia Electric Radiators are easy to install with very basic DIY knowledge. They simply screw to the wall and plug into a normal 13amp socket. Each radiator is supplied with wall plugs, screws, and a template to show you where to put the screws. All you need to do is drill four holes, mount the radiator on the bracket supplied, and plug into the nearest socket. It really is that simple.
We do not recommend electric radiators or panel 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.
Care must always be taken when connecting multiple radiators or heaters to avoid overloading the ring main of your property. If you are unsure, contact a qualified electrician for advice. For a professional installation, cables can be shortened and the heater connected to the mains supply by a fused spur. This work must be carried out by a qualified electrician.
All Haverland Inerzia Dry Stone Electric Radiators come with a 3 Year Manufacturer’s Warranty and a 10 Year Warranty on the radiator body (subject to manufacturer's terms and conditions).

Inerzia Dry Stone TTS RC12 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 radiator heat up quickly and push out heat at greater intensity than conventional radiators achieve, 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.
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, if needed! The Inerzia 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.
This updated version of the Inerzia for 2018 also features adaptive start and open window detection functions, to improve its efficiency and lower running costs. If a window is opened, the Inerzia 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 Inerzia’s temperature is scheduled to change. Rather than starting or stopping the heat at the scheduled time, the Inerzia prepares 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 1800w RC12 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 radiator’s 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 our radiators make them discreet yet stylish additions to any building. Lightweight and compact, Inerzia radiators are astonishingly powerful for their size – a heating solution for larger spaces which doesn't require unsightly bulky radiators. 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.
Installation is simple and fast, a straight-forward DIY task. Simply screw to the wall and plug into the nearest socket. Full installation and programming instructions are included. See installation for more details.
