Lochinvar Introduces Online Water Heater Sizing Calculator

LochSpec Calculator Provides Sizing for Commercial Water Heaters

LEBANON, Tenn. — Lochinvar has released a new online version of its LochSpec Sizing Calculator, which the company said provides a quick and easy solution for sizing commercial water heating systems. Once the user has provided the necessary data, LochSpec uses its formulas to recommend appropriate Lochinvar equipment options, and provides customized energy savings information for the application.

Users begin by selecting the application type they are interested in sizing, such as an apartment complex, athletic club, car wash, nursing home, office building, school, etc. From there, the user is prompted to provide application details to determine peak demand times, durations, and hot water volume. The final step is to input job requirements, which vary depending on the application type. Based on this user input, LochSpec calculates and recommends system options for Lochinvar water heaters, with or without storage tanks. It also provides product specs and an energy savings comparison calculator for each option.

Once the user selects one of the recommended options, they can request that a Lochinvar representative contact them about the application. They can also access a printable application summary report, which includes details about the job, the selected equipment, as well as a breakdown of the sizing formula. Registered users can also save jobs for future reference.

“We developed the new online LochSpec calculator to provide our customers with a simple solution they can rely on for accurate sizing recommendations and energy savings information,” said Mike Juhnke, Lochinvar’s product program manager. “Now, users can quickly see what options they have for the job at hand and compare each one side-by-side.”
