Flo-H2O® Closed Loop Steam Heating

Flo-H2O® with electric actuated steam control valve is a general purpose water heater which is mainly suitable for non-temperature critical applications, such as building heating or anywhere there is a constant flow required.

The Flo-H2O® uses a modulating electric operated control valve to, dependent on the outlet water temperature, vary the amount of steam flowing into the heat exchanger. The Flo-H2O® can generally maintain an accuracy of +/-5°C as long as the changes in hot water demand are not too fast or extreme and +/-1°C in constant flow and closed loop heating systems.

A condensate pump is normally required for good temperature control where the hot water is consumed and there is a fluctuating demand.
