We
are trying to decide on a tankless vs solar water heater w/electric not
gas backup so we can use our solar electric and the New State Premier
Energy efficient power direct vent.
We have a 2 story house with 3
bathrooms, a washer and dishwasher and want a family of 5 to be
comfortable having plenty of hot water. We want to lower our bills and
help the environment. As I said we do have solar but not solar water
heating. Can you give feedback on best?Also why is the New state more
energy efficient than the tankless?

It
is a great idea to take advantage of the free solar renewable
energy, help the environment and reduce the greenhouse gases.
If
you live in southern parts of US, solar water heating can replace over
70% of your water heating costs... and with the electric backup
you are good to go. You have a solar water heater, but no solar water
heating, if I am not mistaken. Expect to pay few thousands of dollars
for solar panels, and other equipment, plus installation. You can take
advantage of the government grants, to reduce the cost.
Tankless
is also good idea, State tankless water heaters are good quality as
other manufacturers and very similar to AO Smith, State parent company.
Look for the EF, energy factor .82 or higher, which are Energy Star
qualified and eligible for government grants also. The average price is
around $1000. I recommend Noritz, Navien, Rinnai also.
Premier
power direct vent you are looking for is the condensing water heater
whose thermal efficiency is over 90 % (here is 96%), and this is
very similar unit (if not the same) as Vertex from AO Smith. Condensing
water heaters are best of the best, they can reduce the cost
significantly due to its ability to steal the energy from venting gases
and therefore increase the efficiency.
State Premier power
direct vent is the 50-gallon condensing water heater but provides
higher recovery rate than 75-gallon conventional State heater which is
more than enough for your size family.
If you keep your options open for other manufacturer, check out tankless condensing like Noritz
for example. Expensive but great. As other tankless water heaters, they
provide an endless hot water, on demand, save on space and have high
thermal efficiency of over 93%.
Look also for the water heaters that are using low NOx burners.

Buy
American. State tankless water heaters are as good as these Japanese or
Korean water heaters. They are using similar gas valves, fans, vent
material, sensors, controls... so why not to support our economy. 505
series is what will suit your needs as their maximum hot water capacity
is 9.4 gallons per minute.
