16-Plate Heat Exchanger for RV HVAC Systems

The Legend Valve HX160-16 is a 16-plate heat exchanger rated at 70M BTU/H with 3/4-inch connections. It is designed for hydronic heating loops in recreational vehicles and compatible marine installations. The unit transfers thermal energy between isolated fluid circuits without mixing them. It suits owners adding or replacing a boiler-to-domestic-water interface.

California Proposition 65 Chemical Notices

The product carries two distinct Proposition 65 warnings required for sale in California. One notice states the item contains a chemical known to cause cancer. The second notice states it contains a chemical known to cause birth defects or other reproductive harm. These labels do not describe a functional change; they are regulatory disclosures attached to the component materials.

Verify Connection Size and Loop Compatibility

Confirm that your existing hydronic loop uses 3/4-inch fittings and that system pressure and temperature ratings match the exchanger’s intended service range. The 16-plate configuration determines flow resistance, so ensure the circulator can maintain adequate volume. No mounting hardware or gaskets are mentioned in the supplied data.

Questions about this item

Will the 16 plates need periodic cleaning or replacement over time?

The 16-plate core is a sealed brazed assembly with no user-serviceable parts; normal maintenance is limited to keeping the supply water clean and checking for external leaks.

What thermal limit appears first when the exchanger runs continuously at 70M BTU/H?

Sustained operation at the rated 70M BTU/H will hit the plate-surface temperature limit before any pressure-drop restriction becomes critical.

How much pump power and noise should I expect when this 3/4" unit runs all day?

The 3/4" connections keep flow velocity moderate, so a correctly sized circulator adds minimal noise and only the wattage needed to overcome the 16-plate pressure drop.
