HRV with 85% efficiency?
Other than Zehnder. Nothing against Zehnder other than the $8,000+ install price tag.
I’m building in Washington State (4-marine) and the energy code requires:
“whole-house ventilation requirements as determined by Section M1507.3 of the IRC shall be met with a heat recovery ventilation system with minimum sensible heat recovery efficiency of 0.85”
I called my regular HVAC contractor and he said he doesn’t have anything that meets that requirement and doesn’t know of any other than Zehnder. Anyone have any ideas for a more budget friendly HRV that can hit that 85% sensible heat recovery efficiency number?
