The Hosford's are a great Father and Son team and installed a Navien NPE 240A tankless hot water heater at our home. They are certified Navien installers so knowledgeable about the equipment and the installation. They were honest, diligent, and offered very competitive pricing. As far as the equipment goes, we could not be happier. Our home is over 100 feet long, has 5 bathrooms and 14 sinks. We had two 50 gallon tanks together at one end and a circulation system. It could run at set times, run constantly (which waisted a tremendous amount of propane) or from a push a button in the house. Basically, the system was inefficient, inadequate and inconvenient. After the Hosfords installed the Navien we now have unlimited hot water and not wasting propane keeping 100 gallons hot. The Navien's built-in circulation system works flawlessly and we find that setting it at 120 degrees is adequate. I looked at several other tankless installs prior to doing our job and none turned out as well (esthetically) and those using other brands had to set the temperature higher to achieve a satisfactory result. Because the other brands did not have a built-in circulation pump they had to use an external pump and have the inconvenience as I previously described or if they had a pump it worked on Wi-Fi which again, seems inconvenient. Navien offers a Wi-Fi add-on however it seems totally unnecessary as, in my opinion, their standard system is by far superior. It monitors the temperature of the circulation line and heats the water in the line when the temperature falls 20 degrees below your set temperature so you always have very warm to hot water at every fixture immediately depending on when the line was last automatically heated. If the circulation line has not been heated for a while the hot water is adequate to start and reaches full potential quickly. -- Of course, there has to be a circulation line already installed in the home for this to work. If not, Navien has a less expensive model without the built-in pump. It takes a knowledgeable installer for this all to work as intended and I recommend Hosford Plumbing. read more
