on demand hot water - how long does it take to get hot water?
Comments (3)The time it takes for the hot water to get to your faucets or shower is related to the distance the water has to travel from the hot water source to the sink and the diameter of the hot water building supply pipe (typically 3/4 inch) as well as the feeder pipe to the sink (typically 1/2 inch). A 3/4 inch pipe holds about 8 ounces of water for every 3 feet of pipe. So if your tank (or tankless) unit is 90 feet away from a faucet, you would have to push out about 1.8 gallons of cold water (plus whatever water is in the feeder pipe, a 6 foot section of 1/2 inch pipe holds about 8 ounces of water) before the hot flows. A typical sink faucet will run at 1.5 gallons per minute maximum flow rate - so you are looking at over 1 minute to get hot water in this scenario. With tankless units, there is also a small delay between the time the unit senses water flowing through it (which triggers it to fire) and the time the unit heats the water up to the set temperature. There are 3 ways you can eliminate the long delay. The first is to put a hot water source (tank or tankless unit) closer to the sinks that are far away from the current source. The second way is to use point of use hot water generators under key sinks that you use. These POU units are very small tanks or tankless units designed to service just once sink. The last method is to install a recirculating loop where you constantly circulate hot water through the hot water building supply. I have a Rinnai tankless system that we installed in the basement directly below the master bathroom. From the time I turn on a shower or sink, hot water is flowing within 10 seconds. That was the good news. The bad news was that the kitchen sink and 3 other sinks that we use often are over 120 feet away from the Rinnai tankless units. Just before we finished the house, we discovered that it was taking several minutes to get hot water at the kitchen sink - and that was unacceptable to us. I wound up installing a recirculting loop. This was not the way I would have preferred to do it, but space and venting in the basement on that side of the house was an issue. You could just live with the delay you have - 1 minute isn't that bad. If you decide to fix the delay, I recommend posting some details on the plumbing forum and seeking advice on how best to correct....See MoreMuffle noise from power vent hot water heater?
Comments (5)Hello. The whine from our neighbor's vent fan, directly opposite our dining room window, has been so severe and at such an unfortunate frequency that its noise could be heard even in the farthest corners of our big house. We tried a variety of acoustic solutions, some suggested on websites like this one - basically following the idea that a longer pipe, or a "tee," or stepping up the pipe diameter, or running it to the ground behind bushes, adequately kills he noise. No go in our case. We ended up piping the vent into an old plastic garbage can filled with discarded fiberfill pillows and comforters. They must be packed loosely enough to allow the very moist hot air to escape freely, but densely enough, obviously, to kill the noise. It's also important to drill air vent holes in the sides, top, and bottom of the garbage can. It's an experiment,but so far, so good. - SL...See Morehelp! new water heater, no hot water!
Comments (9)okay, So, the water comes out of the hot water faucet, but it's not hot. Yet you say that the water heater is hot. Check again to see that you have the cold water line hooked to the cold water inlet on the heater. That side hooks up to a dip tube that goes to near the bottom of the tank. The idea is that the cold water is introduced on the bottom and the hot water rises to the top where the outlet is. The Hot and Cold are marked on the top of the tank. Just confirm that it's right. A less likely problem is that the dip tube is missing or broken so the cold water is introduced at the top and then goes directly out the hot side. I'm taking you at your word that the heater is getting hot (meaning that the elements are working and the power is connected properly)....See MoreHow old is your hot water heater?
Comments (42)I replaced the heater that came with the house when it was about 25 years old, and last summer I just replaced the replacement one. I was a bit annoyed that it only lasted about 10 years or so. I remember the folks had heaters last 20+ years. But yes, that was years ago. Plus my "replacement" one was covered by the recall on the diptube and all seemed well. He showed me about flushing it and I did it quite a bit, slacked off and started noticing more rust in the water. I was a bit concerned but wrote it off as lowered maintenance. Well last summer it started leaking. The one cat came screaming at me and wouldn't leave me alone. I started following him thinking the food dish was empty and he promptly went down the basement. I stopped and when he got to the bottom of the steps, he turned and screamed at me again. I followed him down thinking he was mad about the litter box but he walked past them and into the laundry room. I hesitated, he screamed and I followed. He walked around the furnace, screamed and I finally came around and he looked at me then walked over to the trail of water heading to the floor drain. He stopped, looked at me rather proud of himself, I swore, swore again, swore louder, then he walked over and took a lick of the rusty water! But this time I decided to have it done rather than do it myself. I asked the plumber about how long they should last and he said that getting 10+ years I did real well. He said in this area 5-7 years is pretty common and I groaned. I had a 30 gallon natural gas when I moved in, replaced it with a 40 gallon (gas) and this time replaced it with a low profile 40 gallon gas unit. I only wanted to get a 30 gal to save gas cost but it was more expensive so I figured nope. Wouldn't be prudent. But the new one is supposed to be self cleaning. No idea how that works and the plumber didn't know either! I had looked into the tankless units but after doing some research and thinking about it, they don't save the megabucks that they'd like you to believe. Essentially you'll save the heat loss from the tank which isn't that much. However they should last longer than the tank units so there's a potential savings there. But you have to size it properly. So do a lot of research and get a variety of unbiased opinions on it. Don't forget hidden costs....See Morepeteyboy
