My house built in 2005 is plumb entirely with Pex-A expansion pipe.
The plumber ran a hot and cold header or manifold down the middle of the house approix. 45 feet long. The manifold is 1" pex and all the tee's are 1/2" branch lines for all the fixtures throughout the house.
FYI: I have 6 bathrooms and 2 full kitchens so there are lot of tee's.
The issue I have is I have a oil fired Hot water heater all the way to one end of the manifold and the Master bathroom is all the way on the opposite end.
I am thinking about installing a Hybrid Heat-pump hot water heater located approx 10 feet from the master bathroom and install isolation valves on both heaters so I can choose which hot water heater I want to run. ( the hope is the hybrid unit will deliver and be efficient compared to the oil)
The question comes into all the new hot water heaters I have looked at are 3/4" inlet and outlet. My existing heater is 1" inlet and outlet.
How much difference in flow will the 3/4" compared to the 1" I have now?
Should I run 1" from the manifold to the new hot water heater then reduce down to 3/4" ??
Or
Should I install a 1"X 3/4" reducing tee into the manifold and run 3/4" pex to the new hot water heater??
Does any of this make a difference since all my fixtures lines are 1/2"??
I am leaning towards a AO Smith Voltex Smart Hybrid unit, anybody of experience with this unit or recommend something better??
From the reviews it seems all manufactures are have a % of bad units.
Thank You
