RInnai Water Heater

Is there a way to get hot water faster? It seems to use a lot of water (3+ gal) to get hot in the kitchen which is maybe 15 feet from the unit.

The only way that I have found to work is to place a small electric water heater close to the point of use. Yes this does defeat some of the efficiency of having a tankless water heater but if you figure electric rates are now cheaper than gas rates in some areas, it may save you money.

Another alternative is to put a domestic circulator in-line and recirc the domestic water either all the time or install a timer.

None of these options are "low-buck" options.

15' of 1/2" copper holds less than 1 gallon of water so something is wrong with the heater if it takes 3 gallons to get hot water to the faucet.

My Rinnai is only 3 years old and just recently it is running out of hot water. It has been taking about 10 to 15 minutes for hot water to return. We have well water and we are unsure what the problem is....


The Rinnai relys on good water flow to fire it up. In saying that it runs out of water; thats actually not possible. The Rinnai just heats up water as it goes. Usually fault for installs on bore or well water is a problem with water flow. Causes are blockeed filters or you water pump from the bore starting to fail. I would expect you to have a large filter somewhere on the water line from the well. Try and find it and clean it our. The Rinnai also has a filter. It,s like a plastic round shaped nut just under the heater on the miidle connection. Turn the water off first, it should almost unscrew by hand, take it out and clean it (make sure you don't drop the O ring on it. Also some tapware has water filter right in the end of the spout, check these too. After you tried all this focus on the pump. Make sure no ther water id flowing, try the hot tap and see if it works. Do the same but slowly turn on a cold tap, slowly increasing the flow. Have someone out by the heater and see if the heater shuts down at any point. If it does it could be the water pump at fault. From what you have told me and am certain water flow is the culprit here. Really focus on anything that might lessen the flow before you start messing with the heater. Best of luck.

We have 3 bathrooms, two are close to the rinnai, one is further away. The one that is further away in the early morning fails to get hot. We run the water for 15 minutes and then still sometimes no hot...


chances are that you have a bad faucet that is drawing water from a cold water tap. You will need to have a helper turn on the hot water in that bathroom while you feel the pipes at the water heater and see if they are heating up. If they feel like there is no flow, the water is coming from somewhere and you will need to turn the shut-offs of at various sinks to target the problem faucet. If you find which cold water line is acting up, install a back-flow check valve so the water goes only one way, toward the faucet.

Can't get hot water heater to work - Rinnai Infinity 18


If you can get to the gas valve make sure it is in the on position and not in pilot or off. Does it sound like
a spark ignition system? Even though you say the gas valve is on, by code thered should be a gas shutoff valve located within site of the unit. Follow the
gas pipe until you find such a valve and make sure its on

Does not put out enought heat


Hi this is tech crazy

the solution and reason to the problem mentioned by you is as follows:

As cold water comes in, it remains at the bottom of the tank because it is denser than hot water. If you use the hot water faster than the heating elements can heat the incoming cold water, and if you consume all of the hot water that the tank holds, you run out of hot water in the middle of your shower. If this seems to happen too often, it could mean that the bottom heating element in an electric water heater has burned out or that your water heater is too small for your house. Or it could mean that you are taking really, really long showers.

Hope this helps u a lot

Please do rate me on the above said solution

No hot water - Rinnai tankless hot water heater


sounds like the water line is frozen before it gets to heater. You can take a blow dryer and try to thaw the line.You should be able to hook up a hose on the hot side of water heater. turn valve off so it wont flow into house.You can turn on hot water valve on in kitchen but you will have to thaw cold and hot line. Make sure you know where water shut off is to the house just in case a line breaks.

Piping of these heaters in tandem is critical. Specified by Rinnai in their design manual, the cold water should be piped to both water heaters with a back-flow presenter installed before the first heater. The hot out piping should be "Tee-d" together and going to your hot water needs.

If piped as per the manual, try turning the water off to only one of the units. Turn on a hot water tap and see if the unit stays on without interruption. Then try the same on the second unit. You may find that one unit has a bad flow control, which is shutting off the flow of water.
