FIELD: agriculture, in particular, agronomical equipment for heating water used for plant or seedling growing in greenhouses, hotbeds for small-scale agricultural production, in horticulture and home's ground. ^ SUBSTANCE: water heater uses capacity of water to accumulate solar heating energy realized by means of hangover construction made from elastic water-tight material, such as vessel made from transparent polyethylene film hose heat-sealed at its ends to define closed bag resembling "pillow". Supporting bar or pipe is inserted into cut-off upper corners of vessel. Vessel is hung on bar or pipe, which may be suspended from roof ridge beam under greenhouse roof. One side of vessel facing south or all sides of vessel are blackened. End of flexible hose with weight is lowered into vessel and fixed to supporting bar at site where hose extends from vessel. Other end of hose is lowered and connected to valve at the level below vessel. Water in vessel intensively absorbs infrared component, eliminates overheating in greenhouse, hotbed etc. At the end of day, when solar radiation intensity decreases, water in vessel transmits heat into environment. ^ EFFECT: simplified construction and reduced temperature drop in greenhouse, hotbed etc. ^ 4 dwg
