My apartment has no heating radiant. I have this state of the last 2 weeks, and are not hot zone despite the rain cooled off over the weekend. The kitchen is small and has a ref. Elect. wide and dishwasher. Is the hot zone in the region near a dishwasher concentrated, but not in other parts of the kitchen. What kind of service, should call the company to revise them. Should I point the fire department. check the house?
