1. What does Quinn Radiators sell? For over 40 years, Quinn Radiators has been known as a manufacturer of steel panel radiators. These radiators are available in 4 types: Sensa, Quattro, Integrale, Ligna, Compla en Verti. The Sensa, Quattro, Integrale, are available in 6 different heights and 18 lengths. The Ligna, Compla en Verti, available in 24 configurations, completes our comprehensive range of panel radiators. To complement our product range, Quinn Radiators has for many years supplied design radiators. The range of design radiators is very diverse and contains: bathroom radiators, and vertical panel radiators. A limited range is stocked in Belgium, whilst the complete range is available to order.

2. What makes a Quinn radiator different?

3. Why does the Quinn radiator gives more heat output? The Quinn radiator has higher heat emissions by his unique concept. Thanks to the narrow water channels, Quinn succeeded in attaching directly more convection strips to the water channels. The contact surface will increase; thanks to welding the convection to the water channel, the heat emissions increase considerably. The Quinn radiator also has lower water content, so he will heat up faster and he will give you more quickly the desired warmth in your home or office.

4. Why do heat output for Quattro radiators and Integrale radiators different from Sensa radiators? The heat outputs for Quattro or Integrale are slightly lower then the heat output for a Sensa radiator. The Quattro and Integrale radiators are nicely finished with side panels and a decorative grill. This slightly restricts air flow which is fundamental to high performance. The exact heat output figures (measured according to EN 442) are published in our technical catalogue and pricelist.

5. How to work with the conversion factors in the technical catalogue? Since January 1st 2002 all radiators have to be tested according to EN 442 standards. These heat output figures can be found in our technical catalogue. These values were tested with a temperature regime of 75/65/20 or a delta T50 and also published that way. It is however possible that you have an installation with different supply and return temperature. It could also be that the required room temperature is different. In these cases you can also use the figures detailed in our technical catalogue. You need to use these figures in combination with the conversion factors which you can find at the back of the catalogue. The use of this table with conversion factors can best be explained using two examples: (a) Suppose that according to the technical specifications you have to place a radiator in a kitchen with a heat output of 1500 Watt at a temperature regime 80/60/22. Which radiator do you have to select in the list with outputs according to 75/65/20 ? In the table you will find a multiplication factor of 1.07 at 80/60/22. So, you are looking for a radiator that according to EN 442 75/65/20 gives a heat output of 1500 x 1.07 = 1605 Watt. (b) Imagine in the table you see a radiator with a heat output of 2000 Watt according to EN 442 75/65/20. You want to know what the heat output of this radiator will be when you install it with a temperature regime of 90/70/20 ? In this table you will find a factor 0.8 So in your installation of 90/70/20 this radiator will give a heat output of : 2000/0.8 = 2500 Watt.

6. What is EN 442 ? Difference with NBN 236? As of January 1st 2002 a new norm for measuring the heat output had been installed in Belgium, the Netherlands and Luxemburg. The new norm EN 442, ends the use of different norms which were used in the Benelux-countries. In most European countries this norm EN 442 is already in use and published for several years. As per January 1st 2002, Belgium, the Netherlands and Luxemburg will also use EN 442. Across Europe, one uniform method of determining heat outputs of radiators and convectors is used. This new norm measures heat output at a supply temperature of 75°C, a return temperature of 65°C and a room temperature of 20°C. This means an overtemperature (= average difference in temperature between object and the environment) of 50 degrees Celsius. Prior this was 60 degrees. The new catalogues and technical publications of radiator manufacturers, will be based on the new standard. This new standard does not affect the characteristics of the radiator. Because of the new measurement according to EN 442 the published heat output figures do change. The changes due to the new norm reveal itself in the T, which indicates the average difference between the water temperature in the radiator and the air around it. With the introduction of EN 442, testing facilities need to meet with new requirements regarding the measurement of heat output and determination of other quality characteristics of the radiators. In the whole of Europe, there is only one valid method of measuring since January 2002. The heat output is measured by placing a radiator into a testing cabin of 4 x 4 x 3 meters. The radiator is placed free next to one side. All walls, except for the wall behind the radiator is cooled by means of water, so that the temperature inside the cabin is 20° constantly. The radiator is then heated with water with a supply temperature of 75° and a return temperature of 65°.

7. Warranty for radiators? All Quinn radiators come with a 10 year warranty against manufacturing defects, at the condition that all radiators have been installed by a qualified installer with appropriate use and maintenance.

8. Does Quinn Radiators have an ISO-certificate? For Quinn Radiators, quality is a priority. We are therefore very proud of the fact that Quinn Radiators is ISO certified. Quinn Radiators has the ISO 9001 certificate for its complete production process. Quality of our products comes first.

9. Sounds in your radiator? Sounds in your radiator can have different causes. If you constantly hear the sound of running water in your radiator, this means that you have air in your installation. This can be solved by means of the air vent. Your radiator can also make a ticking sound. This is mostly due to the contact of the brackets with other materials, such as the radiator itself. The sound absorbing plastic inserts need to be placed on the bracket to prevent this. These plastic inserts are delivered together with the brackets.

1. Sensa, Quattro, Verti and Verti Compla will have L-brackets, a ventilator and a blank in packaging. L-brackets will be visible very well, so you cannot miss them in packaging. Thanks to this concept, the radiator can be installed, without removal of packaging.
2. Integrale: thanks to his unique concept, radiators type 21 and 22 are reversible. Type 33 is reversible too, but the tap will come further away from the wall.
3. Compla and Ligna: The ingenious, mechanical anchoring of the front plate guarantees a long life and easy maintenance.
