Help me choose a hot water heater, recirc pum, tankless or vertex
We are in the process of building a house. Currently our plan includes a 75 gallon tank located in the garage. We have a 2 story home, about 4000 sq ft. 2 baths(1 is guest, used infrequently), kitchen, laundry down. 3 baths, stackable laundry center up. We are concerned about getting hot water to the other side of the house where the master bath is located. We have 4 very young children, under 8 yrs old. So not alot of simultaneous morning showers now, but that could come in a few years.
Here are our options:
75 gallon w/recirc pump = $1800
two 50 gallons w/recirc pump = $1800 + $575
Tankless Rinnai (adequate for 2 showers running same time)= $1408, if we need 2 smaller system add $1442
50 Gallon Vertex On Demand = $1771
The Vertex seems to be a good option if it can provide us with enough hot water?
Please give me you opinions/experience!
