The hydronic design seems efficient. After the thermostat shuts off the heater, it continues to throw heat for several more minutes. Sensible design. I am considering retrofitting my entire house with this type of system.

I purchased this product because I added an additional hydronic baseboard heater to a project I completed earlier this year. I used the same brand and type of heater because I liked what I bought from you on my original order. It has performed excellently! We installed a fairly large solar electric system this past December. Part of the conversion is over to using solar/electric heat instead of our gas heating system. I also really like hydronic heaters versus the less expensive baseboard heaters. It provides silent, even heating. I would recommend this to others.

Optional Accessories Available For The QMark Baseboard Heater HBB Models

25 amp at 120-277 Single Pole Thermostat HBBT1: Single pole thermostats break only one side of the power line to your heater and cannot be turned ''off.'' Therefore, power is continuous to the heater even if it is not running. The control knob will have a low temperature setting without an ''off'' position. These thermostats generally have a temperature range of 40 to 90 degrees. The thermostat attaches in the end cap of the heater.

Duplex Receptacle 15 amps at 120 VAC HBBDR: An optional accessory that attaches and makes an additional two plug outlets for any baseboard heater. This accessory will add 8 inches to the length of the baseboard heater as it attaches to the end cap of the heater.

25 amp at 120-277 VAC Double Pole Thermostat HBBT20: A "Double Pole" is an older term for a switch that allows you to turn both sides of the filament on and off - actually turning it completely off making it much safer than leaving it always energized. Double pole thermostats should be used for zonal heat systems such as electric fan heaters, baseboard heaters, and radiant heaters. This thermostat attached within the end cap.

Two Pole Tamper-Proof Thermostat: A standard two pole thermostat but with a tamper proof guard that resembles a small disc covering, which is only removable with a screwdriver. Once it is off, an inside stem is clearly visible. This is then rotated with a screwdriver or with your fingers. This thermostat attached within the end cap.

Inside Corner CBDCIC: Allows two baseboard heaters to be set up next to each other on walls that are at a right angle to each other. If you were standing in the corner, the point of the corner would point away from you.

Outside Corner CBDCOC: If you were facing the point of this corner, it would be pointing towards you..

AC Outlet 20 Amps at 208/240 VAC HBBAC: This accessory enables you to install a 240 volt 20 amp outlet to your baseboard heater.
