INCLUDES Mounting Brackets This type of heat exchanger is used to heat swimming pools and spas from any hydronic system such as an outdoor furnace. It can also be used in conjunction with an existing gas, propane or oil fired boiler.Specifically, it's used to keep the pool and boiler water separate while providing an efficient means to transfer heat between the two systems.This model can be used for up to a 25,800 gallon pool at a 1°F/hour heat up rate.FeaturesUL ListedLimited lifetime warranty against manufacturers defectsIncludes high quality easy to use mounting bracketsConstructed with corrugated tubes for optimal efficiencyLess expensive, more durable, and easier to install than brazed plate heat exchangers Designed to perform at high fluid velocities with low pressure drops Complete welded construction ensuring strength and durability Due to high flow rates through the exchanger, it's inherently self cleaning Product dataConstruction: 316L stainless steelOutput: 300,000 BTU/hrBoiler (Tube) Side: 1-1/2" FNPT FittingsPool (Shell) Side: 2" FNPT FittingsShell side ports on same side for easiest installationUnits with opposing side ports are also availableNotesStainless Steel heat exchangers are not intended for use with salt water pools.For salt water pools or commercial applications, we recommend cupro-nickel or titanium pool heat exchangers. For occasional (weekend and holidays) use we recommend a 2x multiplier to obtain a 2°F/hr heat up rate.Do not place chlorine in skimmer basket, and if using an auto-chlorinator, be sure to install a check valve between the heat exchanger and the auto-chlorinator).
