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.

even distribution of heat

Would Recommend

easier than I thought to work with, dispersed the heat evenly and made the room it was installed in much warmer

Good.

It seems ok. Installed fairly easily. Product is less robust than the old rusty unit it replaces. Typical of most products today (cheaper build), but I think it will work just fine. Looks good.

Good

So far it works well, just wish I could have gotten just the copper pipe with fins rather than the entire baseboard
