Myson Column Radiators are for use on two-pipe, pumped, indirect, domestic and commercial central heating installations, with a maximum working temperature of 248°F. The system should be designed with particular care taken to avoid air entry or water discharge. We do not recommend the use of single feed indirect circulating pumps, as the possibility of aeration due to water interchange may lead to corrosion. The installation work must be carried out in accordance with recognized good practice, and precautions taken to avoid contamination, which could lead to corrosion. If a corrosion inhibitor or other water treatment is to be used, the manufacturer’s instructions must be strictly followed.
