In this section you can find the most frequently asked questions about Quinn Radiators;
Q. What type of connections do Quinn radiators have?
A. All Round Top radiators are supplied with Bottom-Opposite-End (BOE) connections. All Compact radiators are supplied with Top-Bottom-Opposite-End (TBOE) connections.
Q. What are the tapping to tapping (connection to connection) dimensions of the radiator?
A. The nominal radiator length minus 10mm and 5mm for Compact.
Q. What colour is the radiator?
A. Round Top radiators are painted RAL 9003. Compact radiators are painted RAL 9016.
Q. What is the paint finish?
A. A primer coat is first applied using a 'high throw' electrophoretic anodic paint process. This allows the water based primer coat to penetrate all the way up behind the fins increasing protection to an area which is vulnerable to rusting with conventional methods. A top coat of polyester powder paint is then added to create an attractive, durable and easy to clean finish.
Q. Do Quinn radiators comply to BS EN 442?
A. All Quinn radiators are manufactured and tested to BS EN 442 and carry the BSI Kitemark.
Q. How did BS EN 442 affect heat outputs?
A. The new test method reduced heat outputs by an average of 11.5%. This modification applies to all manufacturers.
Q. What is Quinn Radiators quality management system?
A. Quinn radiators are manufactured under a quality management system that is independently certified by BSI to conform to BS EN ISO 9001:2000.
Q. What is your quality registration number?
A. 7941
Q. What is the effect of bottom-opposite-end (BOE) installations on output?
A. Output testing to EN 442 confirms there is no reduction in heat output with a BOE installation.
Q. How do you convert kilowatts into BTU/hr?
A. Watts x 3.412
Q. Where is the air vent located on Round Tops?
A. Each panel is supplied with a built-in bleed screw which is located under a plastic cover on the back of the panel.
Q. How long is your warranty?
A. Each radiator is under full warranty for 10 years in respect of defective materials and manufacture.
Q. What Delta T factor (DT) heat outputs are Quinn radiators based upon?
A. DT 50°C. A full range of DT 60°C outputs are available on request. However, to calculate DT 60°C simply multiply the watts x 1.2675.
Q. What is DT 50°C?
A. It is the mean water temperature of 75’c flow and 65’c return then minus room temp of 20’c.
Q. What is DT 60°C?
A. It is the mean water temperature of 70’c flow and 90’c return then minus room temp of 20’c.
Q. Which DT temperature should I choose when sizing a radiator?
A. If the boiler temperature operates higher than 70°C, which is normally the case with installations in the UK, choose DT 60°C.
Q. How do I calculate the water content and dry weight of the radiators?
A. Consult the technical information section on each radiator.
Q. Do you manufacture top-bottom-opposite-end (TBOE) Round Top radiators?
A. Yes, we manufacture TBOE to an agreed size, quantity and lead-time.
Q. Should I use inhibitor in the system?
A. It is strongly recommended that the system should be properly flushed and filled in accordance with the British Standard Code of Practice for the Treatment of Water in Domestic Hot Water Central Heating Systems BS7593. Use of a corrosion inhibitor is strongly recommended by the manufacturer. Failure to observe this recommendation will invalidate the guarantee. For in-depth product information, please consult the technical information section for your preferred radiator.
