Heater Dimensions ?


Ducasa Avant DGS radiators are simple to use, good looking and economical to run. Made from recycled aluminium with a tough powder-coat finish, the smooth lines of the radiator hide a multitude of technically advanced design features. The body of the radiator hides a system of discreet aluminium fins, which are heated by a special maintenance free heat transfer fluid.

The components are perfectly balanced to provide fast heat up times, together with sufficient retained heat to ensure a comfortable and near constant room temperature. Some lookalike heaters have a dry convector, ceramic or inertia element, which may heat up quickly but they also lose their heat quickly, producing peaks and troughs of heat resulting in less comfort. Some lookalike heaters cause the air to become ‘dry’, which leads sore sinuses and itchy eyes. Because the surface area of the Avant DGS is much larger it doesn’t change humidity levels and is therefore much more comfortable.

To adjust the room temperature just use the + or – button and let the radiators’ digital system do the rest. Accurate to 0.2°C, the technically advanced radiator will help to reduce your bills by avoiding ‘overheat’.

By pressing both buttons at the same time for a few seconds the 7 pre-set programmes are revealed. Then simply set the time and choose the programme that suits your needs and that’s it.

This clever electric radiator also comes with Open Window Detection, which switches the heater off temporarily when a window or door is opened to reduce wasted energy and help with running costs.

  • Simple to operate traditional feel radiator
  • 7 pre-set programmes if required

How Many Heaters Will You Need?

To ensure your conservatory is warm and comfortable all year round it is important to fit the correct size and number of heaters.
With a newly built conservatory, it may be possible to calculate the heat loss with U-values which are a measure of insulation and then calculate the wattage required, however it is still necessary to decide the best place to install your heaters.

As most people do not have the U-values of their conservatories we have put together the following guidelines to help you decide which heater to buy.

First work out the size of your conservatory by measuring the length and width then multiply the two numbers.


When you know the size, simply choose the box below which best describes your conservatory and multiple the size by the wattage required.

Example: 11.1m2 x 90w (new conservatory) = 999w

Next choose the heater model and the wattage which best suits your requirements. It’s unlikely our heater wattages will match your requirements exactly, so always best to choose the next size up. All our heaters have thermostats which will switch off the heater when the room is warm enough, so running costs won’t increase.

Still unsure what size or model of heater to choose? No problem - call the team at Conservatory Heating - a family business with over a decades experience and here to offer friendly, free and honest advice.
