Shipping Details

Residential hydronic baseboard heating sections provide silent, comfortable heat using hot water from a boiler or water heating system. Utilizing natural convection, hydronic baseboard heat provides the quiet comfort without noisy fan assisted heating which can make a space and dusty. At only 7-3/8" high and 2-11/16" deep, homeowners praise the simple uncluttered look of the HydroTherm HB panels and the decorating freedom provided by the white semi-gloss prime coat.

economical, clean, quiet heat

Would Recommend

Replaced my gas heat with Hydro-therm. It was easy to install, and works well. I have been enjoying it now for more than a year, and my heating bill are less. The heat is clean, and quiet. The rooms maintain a steady temperature, no more fluctuating heat. I don't have to turn the thermostat up very high. It provides great heat.
