14-Plate Double-Wall Heat Exchanger

The Legend Valve 807-034 is a 14-plate double-wall heat exchanger with 3/4-inch connections. It is designed for hydronic heating systems requiring fluid separation between circuits. The unit suits installers working on radiant floor, snow-melt or solar-thermal loops.

Compact Plate Design for Tight Spaces

The 14-plate stack fits inside mechanical rooms where shell-and-tube units would not. Double-wall construction isolates potable water from glycol loops without an intermediate tank. Standard 3/4-inch ports connect directly to copper, PEX or threaded adapters.

Passive Operation With No Power Draw

The exchanger transfers heat through conduction across the plate walls, so it adds no electrical load and produces no fan noise. Thermal performance scales with flow rate and temperature difference across the two circuits. California Proposition 65 warnings apply to materials used in the assembly.

Questions about this item

How many plates limit the flow capacity of the 14-plate double-wall heat exchanger under sustained use?

The unit uses 14 plates in its double-wall construction, which sets the maximum heat-transfer surface and therefore the flow limit during continuous operation.

What noise, heat or power output should I expect when the Legend Valve 807-034 runs all day?

This is a passive heat exchanger with no moving parts, so it produces zero noise, consumes no power, and adds no heat beyond the thermal energy it transfers between circuits.

Which piping connections must I already have to install the 3/4-inch double-wall unit?

You need existing 3/4-inch pipe connections compatible with the inlet and outlet ports on this compact 14-plate heat exchanger.
