䡵 On new boilers… On existing boilers… Install Fuel Smart HydroStat® with a Hydrolevel Electro-Well™ to meet local and state low water cut-off requirements and to provide your customer with fuel-saving Thermal Targeting technology. Replace common Aquastat® models in the field to quickly upgrade older boilers with Fuel Smart HydroStat®. If you choose to add the protection of a low water cut-off, just replace the immersion well with a Hydrolevel Electro-Well™ (sold separately).

How Fuel Smart HydroStat Saves Fuel ® Thermal Targeting The boiler and radiation installed in a house is designed to keep the house warm on the coldest day of the year. For every other day, the heating system is essentially larger than it needs to be. With conventional boiler controls, this “oversized” boiler burns more fuel than is needed to keep the house warm. Fuel Smart HydroStat® uses Thermal Targeting technology to analyze thermostat activity and continually evaluate how much heat the house requires.
