By installing the control on an existing immersion well, HydroStat® can be used as a universal replacement for common Aquastat® models. (see "Note" at bottom for models this will replace) Whether it's a cold start or a tankless coil boiler, Hydrostat® will provide all the temperature functions of the control being replaced.

Or, install HydroStat® on a Hydrolevel Electro-Well (sold separately) to automatically activate the low water cut-off function. With HydroStat® you can add low water cut-off protection to new or existing installations without the added time and cost to install a separate control.
