A heating system, e.g. for a bed mattress or floor sleeping area, has a tube extending in an array from a water inlet portion to a water outlet portion through a sinuous intermediate portion. The heating system has a longitudinal inner area extending centrally along the array and a pair of longitudinal outer areas extending at opposite sides of the inner area along the array. The intermediate portion has innermost runs distributed over the central area, where a sleeping person is most likely to lie, and connected directly to the inlet portion and to one another and outermost runs distributed over the outer areas and connected directly to the water outlet portion and to one another. A pump has an outlet connected through the water heater to the water inlet portion and an inlet connected to a water reservoir; and a water temperature and flow control device is connected to the pump and the water heater. |
