To achieve highly efficient heating of fluid.SOLUTION: A heating apparatus includes: switching elements (34, 35) which are installed on a wall part and turn on and off supply of electric power to a heater; a fluid temperature detection unit (33) which detects a temperature of fluid; a temperature estimation unit (40) which estimates a temperature of an element of each of the switching elements (34, 35) on the basis of the fluid temperature detected by the fluid temperature detection unit (33); and an upper limit determination unit which determines an upper limit of electric power supplied to the heater on the basis of the temperature of each of the switching elements (34, 35) estimated by the temperature estimation unit.SELECTED DRAWING: Figure 1 【課題】流体の加熱を効率よく行なうこと。【解決手段】壁部に載置され、ヒータへの電力の供給をオン／オフするスイッチング素子（３４，３５）と、流体の温度を検出する流体温度検出部（３３）と、流体温度検出部（３３）が検出した流体の温度に基づいて、スイッチング素子（３４，３５）の素子の温度を推定する温度推定部（４０）と、温度推定部が推定したスイッチング素子（３４，３５）の温度に基づいて、ヒータに供給する電力の上限を決定する上限決定部と、を備える。【選択図】図１
