Legend Valve HX100-10 heat exchanger

The Legend Valve HX100-10 is a 10-plate heat exchanger rated at 50M BTU/H. It transfers thermal energy between two fluid circuits without mixing them. This unit suits hydronic heating, snow-melt or domestic hot-water loops in recreational vehicles and light commercial installations.

Suited for high-output hydronic loops

Installers who need a compact plate exchanger for high BTU loads will find the 10-plate, 50M BTU/H rating appropriate. Buyers who require a lower capacity unit or a different plate count for smaller zones should look at alternative models. The Proposition 65 notice also means specifiers in regulated projects must document the listed chemical exposure.

Fits between boiler and distribution piping

The exchanger sits between a heat source and the distribution manifold, requiring compatible circulators, isolation valves and piping on both primary and secondary sides. Its plate construction keeps the footprint small, freeing mechanical-room space for controls, expansion tanks or additional zones.

Questions about this item

What plumbing connections must I already have to install the 10-plate HX100-10 heat exchanger?

You need two 1-inch supply and return lines with compatible fittings so the 10-plate unit can be plumbed directly into your existing hydronic loop.

Can the 50M BTU/H exchanger run alongside an older boiler that only delivers lower flow temperatures?

Yes — the 10-plate design transfers heat whenever a temperature difference exists, so it will still exchange energy with cooler boiler output, just at a reduced rate.

How can I verify the HX100-10 is performing at its 50M BTU/H rating after installation?

Measure the inlet and outlet temperatures on both sides; if the delta-T matches the design spec for your flow rate, the 10-plate exchanger is delivering its rated output.
