Or you could save $2k on materials & labor, and put in a filtered vent fan. You only need around 15CFM per resident.
Household HRVs & ERVs have suspiciously low heat efficiencies for their costs.
- BizarroLand 3y ago85-95% isn't suspiciously low. Where are you getting this information from?
- sbaiddn 3y agoDoes this "filtered vent fan" exchange air with the outside? If not, Im not interested.
- symlinkk 3y agoAre you talking about a fan that simply blows outside air in? Wouldn’t that basically fight what the HVAC is doing? AFAIK the only real solution is an ERV / HRV, and they are extremely expensive (like $10k in my area)
- balfirevic 3y agoNo direct experience, but single-room HRV units look pretty cheap https://www.amazon.co.uk/single-room-heat-recovery-ventilation-system/s?k=single+room+heat+recovery+ventilation+system https://www.amazon.co.uk/single-room-heat-recovery-ventilati...
