Hello, I am planning to have Navien 240A tankless heater with Navicirc valve installed to get hot water quickly.
1. I am told that the navicirc crossover valve does not really make so much difference to get hot water quickly. Is that true? Can anyone give feed back on Navicirc performance ?
2. Also I heard there is a greater chance of getting hotwater from the cold water line in the faucets that are more close to navicirc crossover valve. Is that true ?
3. The check valve suggested to be put in the cold water inlet line above the recirculation line Tee in the cold water line is going to restrict the cold water flow and reduces the quantity of the hot water out flow. Is that true?
4. I have 1/2 inch natural gas line (high pressure though) connecting to the present 50 gallon tank water heater. If I change to Navien 240A should I get the gas line changed to 3/4" dia ?
Please suggest, Thanks in advance.
