I have tankless Bosch unit for whole house but it takes forever to get hot water to kitchen sink. The Bosch unit is by all 3 bathrooms, so hot water there is not a problem, but kitchen is on opposite end of house. I've looked into recirculating pumps, but that seems so inefficient. Since i'm remodeling from flood, i want to install small instahot type unit under kitchen sink. Looking at EEMax unit model HA011240. Anyone have this brand or install this type of setup?
