Range of Materials
Description
Hubbell hot water heating coils are designed to efficiently transfer heat from a steam, boiler water, solar water or high temperature hot water (HTHW) system to the domestic potable hot water system. The primary heat source (steam, boiler water, solar water or HTHW) travels through the tubing in the Hubbell heating coil and transfers heat to the secondary system (potable water) without allowing either system to come into direct contact with the other. Hubbell heating coils are designed and constructed for maximum efficiency and longevity and additional features are readily available to provide the most appropriate style and material of construction for virtually any application.
When you specify and install a Hubbell water heating coil, you will have confidence in knowing the owner will be provided with a trouble-free and long lasting source for hot water.
