    The Adesso is designed for a professional fitting only as an electrician will be required to hardwire the heater to the mains and install the element. Each unit comes pre-filled with thermal oil, however, the element will arrive separately so please ensure that you have both the radiator and the element before booking a contractor for fitting.

    Adesso radiators require a two-person installation due to their weight. The fixtures supplied with each unit are for use on solid walls. If you intend to hang the Adesso on a stud or partition wall, you must consult a professional beforehand. They will be able to judge whether your wall will bear the weight of the heater and advise on the appropriate fixtures required.

    The radiator must be hardwired into a fused spur. Attaching a plug to the cable will void the warranty. This Adesso is designed for horizontal installation only and must not be hung vertically. If you require an upright heating solution, please see our range of vertical Adesso electric radiators.

    Adesso radiators are rated IPX5 and can be installed in a suitable bathroom location by a professional electrician. They must be hardwired and wall-mounted in a location at least 1m away from water sources to prevent surface corrosion.

    We always advise consulting a qualified electrician before having multiple radiators or heaters connected to avoid overloading the ring main of your property. If you are at all unsure about the scale of your project, a professional will be able to provide in-depth guidance.

  • Warranty
    All Ecostrad Adesso radiators come with an 10 Year Manufacturer’s Warranty on the powder-coated finish and a separate 2 Year Manufacturer’s Warranty on the electronic heating element.

  • What You Will Need

Few electric heating solutions offer the prestige of the Ecostrad Adesso, with its high-quality steel body, sophisticated design and precision control. These designer radiators fulfil two room requirements in one: providing comfortable and efficient heat, as well as an elegant accent to any interior design scheme. This version of the Adesso has a horizontal body finished with a slate black powder coating to create a pleasing contrast against your décor.

Programming & Control

One of the most impressive features of the Adesso is its cutting-edge Terma MOA Blue heating element, which offers a level of control on a par with some of our most advanced electric heating systems. Using the Terma BlueLine heating app and a Bluetooth enabled mobile device, you can adjust your Adesso’s heat levels from your phone or tablet with ease and even create a custom 7-day heating schedule. If you don't want to use a mobile device to control the Adesso, the heating element also includes a simple, push-button interface which allows the heater’s output to be increased or decreased incrementally between 1 – 5 stages. The interface is situated on the right side of the radiator and can be rotated by up to 90 degrees for ease of use.

Heating Element

The MOA Blue incorporates a host of other useful functions to make your Adesso convenient and easy to use. If you only want to use the Adesso for a short period of time, you can make use of its convenient timer function. This feature allows the radiator to warm for a restricted 2 hour period, after which it will switch off automatically. An anti-frost mode is also included, which will activate when ambient temperatures fall below 6 °C to prevent pipes from freezing. A temperature sensor in the MOA Blue element limits the maximum operating temperature of the Adesso to 60 °C. As an additional safeguard against overheating, the heating rod also includes a fuse which will cut power to the radiator if it exceeds a temperature of 82 °C.


The Adesso has an IPX5 protection rating, making it suitable for installation in bathrooms, provided it is hardwired by an electrician and mounted at least 1m away from water sources to prevent surface corrosion. This version of the Adesso is designed to be installed horizontally. Please see our range of vertical Adesso radiators for heating solutions that can be installed upright on narrow stretches of wall.

Adesso radiators require professional two-person installation due to their weight. The fixtures supplied with each unit are for use on solid walls. If you intend to hang the Adesso on a stud or partition wall, you must consult a professional beforehand. They will be able to judge whether your wall will bear the weight of the heater and advise on the appropriate fixtures required.

Heating control with a tap of a screen

The MOA Blue heating element supplied with the Adesso comes with Bluetooth connectivity built in and is designed to be paired with the Terma heating app. When downloaded to a smartphone or tablet, it offers effortless programming using an intuitive user interface so you can make quick changes to your heating without having to physically crane over the heater. Bluetooth programming means that as you move from room to room, your heating controls move with you, and if you want to increase the temperatures for your heating, you don’t even have to leave your chair. All the control you could ever need is in the palm of your hand.

Keeping an eye on your energy usage

Use the Terma Blueline heating app to help keep track of your energy usage. Through the app, you can view energy usage statistics for every heater in your system over a course of days, weeks, months and years, giving you a top-down view of how efficiently your system is operating. If some heaters are using more energy than you’d like, you can adjust their schedules and temperatures accordingly so they use less power and streamline your running costs at the same time.

Maximising efficiency with zero effort

Ecostrad Adesso electric radiators are filled with thermal oil to provide a slow cool down time and maximum comfort throughout the day. Even when the Adesso stops drawing power from the wall, the heated fluid inside the radiator means that it continues to emit heat for a long time afterwards so your heaters don’t need to use as much energy to keep rooms warm. The lasting warmth of the Adesso reduces running costs over time so more money stays in your pocket.

Lot 20 Compliant
With weekly programming and adaptive start control via its heating app, the Ecostrad Adesso is fully Lot 20 compliant for energy-efficient heating.
Low Maintenance
The Adesso never needs bleeding or annual maintenance so you never need to spend money on upkeep.
Quick Installation
There’s no messy plumbing needed for the Adesso. A professional electrician will be able to easily hardwire this electric radiator to the mains of your property.
