“Hot water distribution works well -- no more than 20 seconds for hot water to arrive at any fixture in the house without pumps. We are currently using [the ERV] continuously to circulate air around the house with 20 min./hour of outside air introduced. This has helped maintain indoor humidity when outdoor RH is lower.”
