Discuss Range rating for a Grant Vortex Pro External Condensing Combi Oil Boiler 26kW in the Plumbing Jobs | The Job-board area at PlumbersForums.net
Indeed I do. The boiler can only achieve max efficiency by leaving the condensate within the heat exchanger to deliver its latent heat to the system, not the air outside. The
rating is too high for the system load.
