Compact Steam Fired Water Heater
The Hubbell PS model is a point-of-use storage water heater
that utilizes steam to heat domestic water. Its compact
design takes up minimal floor space and eliminates the
need to rely on oversized instantaneous heaters or large
storage heaters for your low to medium demand hot water
requirements. The Hubbell PS model is constructed for
demanding commercial and industrial applications by utilizing a heavy duty storage vessel lined with specially
formulated Hydrastone cement and copper-silicon threaded
tank openings to ensure a long lasting and energy efficient
water heater. When you specify and install a Hubbell PS
model water heater, you will have confidence in knowing the
owner will be provided with a long lasting and trouble-free
source for hot water.
