Everhot & Therma-Flow Indirect and Oil-Fired Water Heaters
A.J. LeBlanc Heating installs Everhot and Therma-Flow water heaters across Southern NH. They're the same Northeast manufacturer ("tfi everhot"). Glass-lined oil-fired tanks and indirect tanks built for NH homes already heating with oil, known for long service life and high recovery rates.
One Manufacturer, Two Brand Names
Everhot and Therma-Flow are the same Northeast water heating manufacturer (Therma-Flow, Inc., often branded "tfi everhot"). They have supplied the New England plumbing and heating trade for decades. Their tanks are glass-lined for corrosion resistance and built for the high-demand recovery typical of NH homes already heating with oil. The "Everhot" name covers their oil-fired tank water heaters; the "Therma-Flow" name covers their indirect water heaters and storage tanks. Both are excellent fits for homes on oil heat.
