Correct radiator sizing begins with the room heat loss, not with a visual estimate. An undersized radiator may fail to maintain the required indoor temperature, while unnecessary oversizing increases cost and can complicate system balancing. Distributors and project buyers should therefore use a consistent method when comparing products and preparing quotations.<\/p>\n
Heat loss depends on outdoor design temperature, required indoor temperature, wall and roof insulation, glazing area, ventilation and air leakage. A qualified heating designer calculates the required watts for each room. The radiator schedule can then be built around those loads.<\/p>\n
Radiator catalogues often publish output at \u0394T50. This temperature difference represents the relationship between the average water temperature and the room temperature. Low-temperature systems, including many heat-pump applications, operate at a lower \u0394T and therefore produce less output from the same radiator. Buyers should request conversion factors or tested output data instead of assuming the \u0394T50 figure applies to every system.<\/p>\n
Recesses, covers, curtains, restricted airflow and unusual mounting clearances can reduce effective output. The selected radiator must also fit the available wall area while leaving space for brackets, valves, pipework and cleaning. Connection centres should be confirmed against the drawing before production.<\/p>\n
When sourcing from different manufacturers, compare the same radiator type, dimensions and temperature conditions. Check whether outputs are supported by recognised test methods. Also review water content, weight, working pressure, coating and connection specifications because these affect transport, installation and long-term use.<\/p>\n
SUNLIKE works with importers and heating-sector customers to prepare practical product matrices for their markets. Matching dimensions and radiator types to real project demand can reduce excessive SKUs and improve inventory turnover. For OEM programmes, technical data, labels and packaging should all communicate the same tested specification so distributors, designers and installers receive consistent information.<\/p>\n","protected":false},"excerpt":{"rendered":"
