Lochinvar Gas Pool Heaters

Natural Gas and Propane Pool Heaters by Lochinvar

Lochinvar gas pool heaters are designed with customer-satisfaction in mind. The highly-engineered design features several components that distinguish the Lochinvar brand from its competitors. These gas pool heaters come in sizes starting at 150,000 – 400,000 Btuh and are available to run on either natural gas or propane. Lochinvar leads the industry in innovation and has created pool heaters that are unrivaled in their short heat-up time, all while saving money on energy.

Advanced Design
All of Lochinvar’s components are designed with advanced technology and separate their gas pool heaters from the rest of the industry. Their heat exchangers are designed with copper-finned tubes and without O-rings to eliminate leaks and failures. Polymer headers resist most types of corrosion, and with options for slip-fit or threaded connection. The combustion system uses Direct-Spark ignition for reliable start-up and features stainless steel burners for maximum efficiency. The sealed combustion chamber is designed to maximize efficiency and keep out unwanted spiders and pests, all constructed with durable stainless steel. The combustion chamber is surrounded with a layer of Loch-Heat ceramic tile to maximize the transfer of heat to the heat exchanger for powerful and efficient energy use.

Easy-to-Use Technology
With all their advanced components, Lochinvar gas pool heaters are still easy to use. The digital display allows for simple temperature scheduling, and comes equipped with a diagnostic menu for convenient access to heater operation. The display pad also has password protection to prevent tampering. Set-up is simple, with a flexible terminal strip for convenient wiring of third party controls. Plumbing installation is also flexible, with capabilities for PVC and CPVC connections. To top it off, each model comes with a built-in floor shield, giving owners the ability to install on a combustible surface. The Lochinvar brand goes to great efforts for their customers, making sure that every feature of their gas pool heaters is accessible and easy to use for pool owners.

Additional Features
To further improve your pool experience, Lochinvar offers a number of additional features to their line of pool heaters that can increase the convenience of using your unit and extend its lifetime for several years. Each pool heater comes with the option for a Cupro-Nickel heat exchanger, made of a highly-engineered alloy that is designed to better resist corrosion while improving energy transference. Units have standard outdoor venting kits, but Lochinvar can also provide a versatile indoor venting kit to conveniently improve the installation flexibility. For commercial pools, there is the option for ASME-Certified models which include a ASME Pressure Release Valve and glass line header. In addition, Lochinvar offers a Multi-Stack Frame for indoor installations where multiple heaters are required, thereby reducing the overall footprint.
