Question about Bosch AquaStar Propane Tankless Water Heater #125HX-LP

1 Answer

I need to convert this water heater to natural gas. Is there a kit available to do this?

    So there is no kit, but can it be converted. The black pipe and copper pipe is a connection issue, and should not have an effect on changing out the regulator and orifices. The NG unit's heat exchanger is surely copper or stainless.

No kits are available to convert his unit to NG. This is because the LP uses copper pipe and is within code, the NG uses black pipe and each unit is specifically designed, entirely, to use the gas associated with the unit.

    Ok,I just posted what the manufacture recommended and say's. I suppose that is why they make two different units, one for NG and one for LP.

Can i convert a Rheem ECO 180DVP (LP gas unit) to a natural gas unit ?


Rheem water heaters should not be converted from propane to natural gas. The burners have been optimized for the rated gas and will not work as well after conversion. (Unlike ranges where the gas/air flow ratios can be adjusted when the burner orifices and regulator are swapped, the water heater doesn't have that option.)

I wish I had better news for you. I recommend you get a new water heater for the LNG service; it will be safer and more efficient.

How do I convert my rheem water heater from lp to natural gas model#21vp40-1p


Call Rheem
Generally the company does not support changing type of gas since propane burns much hotter and has more pressure than natural gas.
You need different gas control valve, and need cast iron burner and orifice than matches that specific gas control valve.

I bought a AQ125BNG from my neighbor and when I read the instructions it says to use a gas pressure regulator on the AQ125B but I dont know if I need it on my AQ125BNG too is not that clear. I will ap


The NG at the end of the model # means natural gas. If you have a nat gas meter outside on your home, the regulator is already there. If you have propane gas for your home, then the control and the appliance needs to be converted to propane, if the conversion kits are available. Call the manufacturer if you have any doubts.

Can you convert a natural gas rc80i n waterheater to propane


Contact manufacturer.
Generally the answer is probably no, especially if you have a family, children, dog and neighbors.

Propane burns Hotter and has more pressure than natural gas.
Burner must be more robust cast iron.
Orifices must be changed to accommodate different gas.
Different gas control valve needed.
In some cases there are dip switch changes for type of gas and altitude above sea level ... the higher the elevation, the hotter gas burns.

Here is expected result from changing NG to LP.
But your good luck might lead to less volatile result

Change orfis in water heater


Do NOT do that.
If you put LP gas to NG heater you can cause explosion.
Contact manufacturer and see if they sell conversion kit. Most do not.
