Tankless water heater for family of 4+1?

Question

Is Tankless water heater good choice for 4 adults + 1 baby in a house with 2.5 baths + kitchen + laundry...

Palomo brand has 7.2 Gallons per minute... Is this good for my case?

Answer 1

Depends on your usage and your incoming water temperature. That 7.2 gpm is not at 45o F. The lower the incoming water temp, the lower the output. The higher the temp of the water heater the lower the output. If you run your washing machine on hot, your dishwasher, and try to have two showers going it isn't going to work. Generally a gas powered will deliver enough to power two high flow fixtures at the same time and four low flow fixtures at the same time. If you have low flow showerheads and pressure balanced shower valves you'll be fine. If not, try to find out the lowest water temp in your area in winter. Low flow shower heads deliver 2.5 gpm @ 60lbs of water pressure, keep in mind that some of that 2.5gpm is cold water. 7.2 gpm is more than enough, 5gpm is more than enough. The question is will it really deliver that.



* I just checked the Paloma site. The 7.4 unit will meet your needs. It delives 5.3 gpm @ 40oF with the unit set at 104oF.

If you live up north, you'll want to set it low like that in winter. 125oF is where most heaters are set. With a baby in the house you probably want it close to that anyway. Go for it dude. It will save a lot of energy, reduce emmisions and deliver endless flow of hot water. Also check out Rinnai heaters. The Rinnai Continuum will deliver the same with a 65o temp rise (40oF - 104oF) but will deliver 8.5 gpm compared to the Paloma's 7.6 gpm with a 35o temp rise (70oF - 104oF)

Answer 2

gazing the position/area accessible and the proximity to the various centers the position the heated water will be used the 7.2 GPM ought to nicely be adequate. Given there ought to nicely be 3 showers using the heated water rapidly plus added use at different factors i ought to signify you concentration on a separate heater with a lot less volume for the laundry and kitchen factors. 7.2 divided by using 3 will provide 2.4 GPM to each and each of the three furnishings, that's probably pushing the means of the only heater. evaluate the run from the heater to the most suitable use discharge because the water ought to ought to warmth each and each of the piping before its use on the wanted temperature.

It depends on whose unit you are going to use. Some manufacturers have limits on their equipment. Some require a certain water pressure and temperature to operated properly. If you have a well water system I wouldnt try to use them. A good unit that I have installed is called Takagi. They are very versitile and give unlimited hot water. Check them out.

Take into consideration the size of your electrical panel. These things need a lot of amps. This size should be plenty big enough for your family.
