Boiler Report: Lochinvar

Share With:

Lochinvar’s heritage of excellence dates back to 1939, when the company was founded. The introduction of the Power-Fin product line in 1986 revolutionized the industry and helped establish Lochinvar as the leader in advanced hydronics and water heating technology.  Through the years, Lochinvar’s continued investment in research and development has produced many of the industry’s most innovative products and technology.  Today, with company headquarters in Lebanon, Tennessee, Lochinvar is the leading manufacturer of energy-efficient water heaters, boilers, pool heaters and commercial solar thermal systems.


In our series of boiler reports, Mechanical Hub recently caught up with Jeff Vallett II, product manager, Lochinvar to talk Lochinvar boilers.

The Lock-Temp Stainless Steel Storage Tank is a fully welded and passivated stainless steel storage tank for potable water.

The updated SHIELD line now includes three additional models, extending the offering from 125,000 Btu/hr to 500,000 Btu/hr, and an extensive list of upgrades that are all designed to improve performance, accessibility and — ultimately — customer satisfaction.

MH: What are two commonly asked contractor questions regarding Lochinvar & its products, and how do you address those questions?

JV: Is Lochinvar a foreign company? Lochinvar is actually the name of a knight found in Sir Walter Scott’s poem titled, Lochinvar. Many people think that with a Scottish name like Lochinvar, it must be a foreign entity. However, Lochinvar is proud to have roots in the Detroit, MI and Nashville, TN areas. Lochinvar is proud to be an American manufacturer with world headquarters located in Lebanon, TN, USA.


What kind of products do you make? Many contractors know us for one or two products within a specific product segment. The most common reaction is that of surprise when visitors to world headquarters see the breadth of Lochinvar’s product line. Lochinvar manufactures the most complete offering of residential and commercial water heaters, boilers, swimming pool heaters and solar thermal heating systems. Water heaters range from 2-gallon under the sink models to multi-million Btu/multi-thousand gallon water heaters used in commercial applications. Residential to commercial hydronic heating boilers and pool heaters are a core strength as well. Finally, Lochinvar also has customers covered with commercial solar thermal systems. With a product offering this full, nearly every project that involves heating water could also involve Lochinvar.

MH: What do you believe are the two toughest things facing contractors today and how are the problems rectified?
JV: Differentiation—it is a very competitive market with multiple contractors bidding on the same job many times. Finding a way to make your company standout can be a challenge. One way to differentiate your business from the competition is by offering quality, high-efficiency products from reputable manufacturers.

In addition, it’s essential to stay up to date with technology. There are new products being introduced constantly, and while keeping up to speed can be a challenge, it’s also extremely important in keeping your business ahead of the competition.
