Going to put two 40 gal water heaters into a 3773 sq ft new house utilizing pex manifoild blocks for . 3-4 bedrooms with master on opposite side from kitchen, laundry. For when just my wife and I are there, i.e. no company, does it make sense to put a tie line between PEX manifoild blocks so that only one water heater can service the whole house??
