Options for Wiring a Tank Less Water Heater
My main service is 200 amp
- I have a single 2-pole 60 amp going to my my sub-panel.
- Currently I have a single 2-pole 40 amp circuit going to electric range oven.
- I do have plenty of spare empty slots in the sub panel.
- The wire going to sub panel is 6-3 Romex.
Here is my main question:
- I want to replace my old water heater with tankless one that requires two 2-pole 40-amp breakers or other model calls for single 2 pole 60 amp.
- What are my options?
- The range oven has to stay
- I can not bring new wires to the sub panel
- It is 50 feet to the main panel
- Everything in the house is finished
Please help before purchase. Thank you. Happy holidays!

Thanks for your electrical question Alex.
Electrical Wiring and Circuit Requirements for a Tank less Water Heater
- You will need to install the required circuit for the tankless water heater that you select.
- If you need additional space in the circuit breaker panel then you can purchase and install a Quad circuit breaker which will create the 2-pole circuit that will be required.
- You may also install twin circuit breakers to replace the existing full size circuit breakers which will create the space for the new circuit as well.
