Are there any "best practices" for whole house drain heat recovery (DHR)
retrofits? By whole house, I'm also including the basement drains that
serve basement bathrooms and laundry. Sometimes upper floors also drain
into pipes that are embedded into the basement slab.
Is a small catch basin + sewage sump pump that lifts the drain line to
drop back through a DHR a viable solution? This would ideally include a
overflow bypass in case the sump pump fails for whatever reason.
Any comments/opinions are welcome.
