Question about Rinnai Air Conditioners

1 Answer

We have installed a rinnai water heater in the basement. Since it takes a little time before the hot water arrives in the kitchen or upstairs in the shower, we are wasting qite a bit of potable water every day. What is the best/most energy efficient way of avoiding the waste of a precious resource like water? Installing an electric water heater? Many thanks for and best regards. Bettina

The only way to reduce water waste would be to have a plumber install smaller pipes coming from the water heater to each individual point of use. The normal way of plumbing a house uses a large pipe that has smaller pipes that go to each sink, tub, shower, etc. The larger the pipe, the more water is in it and the longer it will take to get hot water to where it is going. An electric tank won't save you from wasting any water unless you have a separate hot water circulation system installed. This would keep the hot water drawn out to the far ends of the plumbing system and allow the hot water to reach it's destination alot sooner. However, keeping a tank full of water hot is not economical and a circulation system basically turns your pipes into a radiator causing you to waste electricity. I know it may seem that you are wasting alot of water waiting for the hot water to get there, but in the long run you and the environment are coming out ahead due to the saved energy and efficiency of the Rinnai unit. Also just in case you were thinking of it, a circulating system is not compatible with a Rinnai water heater.

I agree with you. The foam insulation should only be on the Hot Water side. The cold water side doesn't make any difference, as that temperature rarely changes in California.

Hope this helped you AK, thanks for choosing FixYa.

We have a brand new Rinnai gas heater, Avenger 25. The first two times we operated it, it was fine, but since then a code 13 comes up after 3-4 minutes and the heater turns off. Rinnai said we could...


These are the possible issues with the unit, based on the code list and description

Check that the gas is turned on at the water heater and gas meter. Check for obstructions in the flue outlet.
Ensure gas line, meter, and/or regulator is sized properly.
Ensure gas type and pressure is correct.
Bleed all air from gas lines.
Ensure proper Rinnai venting material was installed.
Ensure condensation collar was installed properly.
Ensure vent length is within limits.
Verify dip switches are set properly.
Ensure appliance is properly grounded.
Disconnect keypad.
Disconnect EZConnect™ or MSA controls to isolate the problem.
Check power supply for loose connections.
Check power supply for proper voltage and voltage drops.
Ensure flame rod wire is connected.
Check flame rod for carbon build-up.
Disconnect and re-connect all wiring harnesses on unit and PC board.
Check for DC shorts at components.
Check gas solenoid valves for open or short circuits.
Remove burner plate and inspect burner surface for condensation or debris.

Clean inlet water supply filter.
On new installations ensure hot and cold water lines are not reversed.
Check for bleed over. Isolate unit from building by turning off hot water line to building.
Isolate the circulating system if present. Open your pressure relief valve; if unit fires, there is bleed over in your plumbing.
Ensure you have at least the minimum flow rate required to fire unit.
Ensure turbine spins freely.
Measure the resistance of the water flow control sensor.
Check for DC shorts at components

We are a bit confused by the device that you are using to heat the Hot water with- Is it an instantaneous HW heater?--
They are pressure sensitive-- Could it be, that your water pressure drops momentarily, (which causes the instantaneous heater to shut down its flame-- and you get a pulse of Cold water.)

If your hot water is a tank-- It is possible that something is cycling your hot water away-- like rinse pulses on the Washing machine)-- or your dishwasher?

I would suggest that you turn temperature setting up to 140 degrees and see if this won't help you. Obviously with water temperature that high make sure no little ones are left unattendded. Thank you

I have just installed a new gas hot water heater. All faucets are running except the kitchen. Do I have a vapor lock? If so how do I fix it. Thanks


Unscrew the aerator on the bottom of the faucet, alot of times when a water heater is changed out
rust deposits can break free from the pipe and clog up. Run the water until clear, if nothing comes
out you may have to take apart and clean the faucet.

Looks like your recirculation pump might be bad. If your opening a valve close enough to the heater and it comes on, It sounds like it's giving your pressure switch a false reading and allowing it to come one while the farther away you get, it is not enough line pressure to overcome the safety's of the heater.

4 problems: I am the homes second owner - I


Hi, let me try and help you locate this filter. They put them on the return side of the system. Depending on the size of you're home, you may have up to 3 or more.Normally, they put them in the ceiling to clean the air as it is drawn back to the blower fan motor.Check through out home to see if they are in the ceiling. If not, go to the unit upstairs.If the blower motor is an up flow with motor above, you should be able to see the filter above the motor.If it is a down flow, the filter should be laying below the blower motor.To sum this up, which ever way this motor is blowing the air would be the supply air flow, and the filter will or should be before the air heading out.It should have an arrow showing the direction of the supply air on the blower housing.The return is the air coming back to the heater, where the filter should be located to catch the dirt and start the cycle again.It could have a grill in the wall next to the furnace, or on the face of the furnace it self.Some will be marked on the furnace and will say return filter excess.It could be that the owner before you removed it, and never installed a new one?There will be some way, grill, in furnace for the air to go back to the blower section. Use a good light to look inside.This loud squealing, sounds as though you have a belt drive blower motor that is worn out.They are on split systems, the older ones.That would be the squeal you hear, go to the furnace upstairs, and by removing panels, you will find the belt and more then likely, the filter section.The belt will have a number on it like, 4L330, 4L460, or even A-37 ect.Easy to remove and replace.A direct drive motor has no belt.It also sounds as though this home has a zone control, using hot water that circulates by the use of a water pump in line somewhere in the system so when it calls for heat, this pump starts sending hot water through out different heating zones in this home, more like a commercial system would have.Gas would heat this water, and flow through pipes to VAV boxes in the ceiling, or maybe your supply vents are on the floor, I don't no this. As for the 9 degree difference in the upstairs and down, could be many causes, as the way this heating system is designed, and what type thermostat controls this unit. It will always be warmer upstairs, as you know heat rises, but you can check the way that the duct work has been installed, and see if indeed this is a hot water zone controlled system.You could have dampers in the duct work controlling the amount of air to different parts of the home that may be shut of causing this much of a differential.Take care of the belt, which you can buy at most hardware stores, keep searching for the filter or filters as they are somewhere on the return side, you may hear or feel the air being sucked back to the unit, that is the return side.Find out by looking for a boiler hot water supply if you have a basement, attic and so on.You will be able to solve a lot of these problems by getting familiar with the way this system is set up. I would like to hear back from you on this.Sincerely,
Shastalaker7
