    Haverland RC Wave Electric Radiators are easy to install with the most basic of 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 exactly where fittings should be placed. All you need to do is drill four holes, mount the radiator on the brackets 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.

  • Warranty
    All Haverland Designer RC Wave Electric Radiators come with a 3 Years Manufacturer's Warranty and Lifetime Warranty on the radiator body (subject to manufacturer's terms and conditions). 1 Year Warranty for Haverland accessories.

  • What You Will Need

Haverland Designer RC Wave RC3W slimline digital electric radiators are energy-efficient with the latest dry thermal technology, a high precision electronic thermostat and fully programmable heating control. Dry thermal elements emit heat by a combination of convection (pushing heat around the room) and radiation (pushing heat out). The precision thermostat is accurate to within 0.2 °C, so the radiator will switch on or off automatically to maintain a comfortable temperature. Fully programmable controls allow you to set a 7 day heating schedule to suit your lifestyle, with different settings for every hour of every day of the week, if needed! This allows you to minimise waste and keep your heating bills as low as possible.

Heating Technology & Programming

The RC Wave range is also mess-free, safe and easy to use. Dry thermal technology uses fully enclosed heating elements with no liquid or moving parts, so our radiators cannot leak, and will not lead to wall blackening. Our radiators come with full programming instructions, a lockable built-in control panel and the option to purchase a remote control which allows you to programme all your radiators without leaving your seat. Integrated computer memory ensures that your settings will not be lost if your radiator is disconnected from the mains for up to 4 hours – a useful safeguard in the event of a power cut.

Design & Quality

The ultra slim, stylish design of our radiators make them attractive, space-saving additions to your home. They're eco-friendly too: the 100% recyclable radiator body is made from high grade recycled aluminium. We’re so confident in the superior manufacturing quality of Haverland radiators that we offer the RC Wave with a lifetime guarantee on the radiator body – read the full warranty here .

The RC Wave is a more economical radiator than comparable Haverland ranges such as the RCA and RCE electric radiator range. The RCA range does not include programming features so each radiator must be purchased with an additional controller. RCE radiators do not come fitted with a plug, so must be fitted by a qualified electrician. With excellent in-built control facilities and suitability for DIY installation throughout the home, the RC Wave is not only a superior heating solution but a more economical choice for your home. 


Installation is simple and fast, a straight-forward DIY task. Simply screw to the wall and plug in at the nearest socket. If you prefer to install freestanding, a set of feet can be purchased separately. For more information, take a look at the complete RC Wave manual.

Available in five sizes: 450W, 800W, 1100W, 1400W & 1700W.

Set and forget, zero-hassle heating

The RC Wave allows you to create a schedule for every hour of every day of the week, so that your heating is completely in tune with the rhythm of your home. Assign comfort mode when you know you’ll be home and enjoy warm and cosy rooms set to your ideal temperature – or, assign economy mode to periods when you know you’re going to be absent to slim your monthly bills and keep wasted energy to a minimum. It’s an intuitive, energy-saving way of keeping warm that’ll help cut costs.

Precision temperature management

Unlike other heating systems that can sometimes be out by up to 3 °C, the RC Wave uses a digital thermostat to monitor your room temperature with exceptional precision, so you won’t waste energy by overheating your space. With an accuracy of ±0.2 °C, the RC Wave never lets temperatures drift too far away from your comfort setting and also means it stops drawing power the second it reaches its target.

Super-slim, super-efficient design

While the majority of heating systems take up valuable room, the RC Wave can be installed in the tightest of spaces, with its minute 75mm depth and lean, compact frame. Make use of those awkward or otherwise wasted spaces that won’t accommodate other radiators and be free to choose exactly where you want your heating. With the super-slim RC Wave, nowhere is off limits.

Automatic, eco-conscious heating

Save money on a day-to-day basis with the RC Wave’s intelligent energy-saving features. To ensure your rooms are warmed to perfection, the RC Wave is able to work out when to start heating ahead of schedule, hitting your target temperature exactly when needed rather than leaving you to wait around in the cold. The RC Wave even knows to stop heating if it detects a strong draught, waiting until the temperature equalises before continuing – only heating when it knows you’ll feel the benefit. The RC Wave’s automatic features do the hard work for you so sit back, relax and enjoy luxuriantly heated rooms without any effort.

Quality engineering designed to last

The RC Wave will keep you warm year in, year out, without any maintenance or call-outs required – just reliable heating time after time. That’s why the RC Wave comes with a lifetime guarantee on the radiator body – helping you to purchase with confidence, safe in the knowledge your heating is protected from day-to-day use.

The RC Wave uses lightweight aluminium heating elements that heat and cool quickly for an agile system that adapts quickly to change.

When purchased with its optional remote control, the RC Wave can be adjusted from the comfort of your chair with a simple point and press.
