PROBLEM TO BE SOLVED: To provide a liquid heating device that does not excessively heat cooling water and can reduce load on a circuit of an electric heater.SOLUTION: The liquid heating device 100 includes: a liquid circulation circuit 1 through which antifreeze liquid circulates; the electric heater 12 provided in the liquid circulation circuit 1 and heating the antifreeze liquid circulating through the liquid circulation circuit 1; and a controller 30 serving as a control part for controlling output of the electric heater 12. The controller 30 regulates the output of the electric heater 12 when viscosity of the antifreeze liquid exceeds a prescribed viscosity threshold.SELECTED DRAWING: Figure 1

    【課題】冷却水を加熱し過ぎることがなく、かつ、電気ヒータの回路にかかる負担を低減できる液体加熱装置を提供する。【解決手段】液体加熱装置100は、不凍液が循環する液体循環回路1と、液体循環回路1に設けられ、液体循環回路1を循環する不凍液を加熱する電気ヒータ12と、電気ヒータ12の出力を制御する制御部としてのコントローラ30、を備える。コントローラ30は、不凍液の粘度が所定の閾値粘度を超えた場合に、電気ヒータ12の出力を制限する。【選択図】図1
