Dimplex Q-Rad
.
Q-Rad monitors the effect of its actions on a room’s temperature. It knows precisely how long it takes to reach the desired temperature and when to turn off as it approaches that target. This minimises the energy that it uses, while maximising comfort – so you stay warm for the lowest possible cost.
Thanks to its low thermal mass, Q-Rad is able to heat up more quickly and react more responsively to changes in room temperature than a fluid-filled electric radiator. This means improved control, comfort and energy saving.

Energy savingEco Start - delayed start anticipatory control
Eco Start is Q-Rad’s unique, self-learning delayed start function. This learns the thermal characteristics of a room then determines how long the appliance needs to operate to reach target temperature according to room size, heat losses, prevailing weather conditions and so on. By measuring the heat-up and cool-down times of the room, and how they vary with external temperature, the heater works out what time it needs to start heating to reach the user-defined target temperature at a specified time. This minimises wasted energy and can deliver cost savings for users. For example, say you plan to get up at 7am and your desired temperature is 21°C: with a traditional system, you would need to estimate when to set the heating to come on to ensure it preheats the room in time. Depending on your settings and the prevailing temperature, this could mean that the room is still cold when you get out of bed or that it has been warm for some time before it needed to be. However, this clever feature means that Q-Rad anticipates when it needs to start heating to reach 21°C by 7am, preheating for shorter periods when the weather is mild and longer periods when the weather is cooler. |

Stylish heatingTaking design cues from their category leading Quantum heater, Q-Rad is sleek, slim and stylish. Combining good looks with flexible installation options, Q-Rad is ideal for use in many applications, including in place of conventional convector heaters or electric radiators.

Dual-element technologyQ-Rad has a convective element with a variable power output, as well as a radiant element. It uses one or both of these heat sources automatically to maintain an accurate target room temperature. Q-Rad calculates the time needed to heat a room and the convective element begins by operating at full power.
As the room approaches the target temperature, Q-Rad begins to cycle the convective element between full and reduced power output until the target temperature is reached. At this point, Q-Rad switches off the convector, thereby avoiding overshooting and saving you energy. To maintain the target temperature, Q-Rad then cycles the convective and radiant elements on and off, as required. |
