Using Splitvolt Splitter Switch with a water heater.
- Herrick Hu
We have many customers who uses the Splitvolt Splitter Switch with their electric water heater with success.
The choice comes down to their decision on whether the water heater or the Dryer/EV charger (or other appliance sharing the splitter) should be the priority.
If they decide the water heater should be the priority, then they can simply plug their water heater into the dryer socket, and the other appliance into the EV socket. This will allow their water heater to ALWAYS have full power, and the appliance in the EV socket will have power when the water heater is in standby (when it’s not actively heating up water). EV socket’s power will be switched completely off when water heater is actively heating up water.
If they decide their Dryer/EV Charger or other appliances should be the priority. Then they can plug that appliance into the dryer socket. Whatever is plugged into the dryer socket will ALWAYS have full power. The water heater, which will be plugged into the EV socket, will have power when the Dryer or EV charger is not actively in use.
Since the water heater will be actively heating the water throughout the day, and is hard to predict, most customer make their Dryer/EV charger the priority, as they are typically used no more than once a day, and the water heater can always wait till the Dryer or EV Charging is done. There has been no reported issue of water heaters, even IoT enabled water heaters, return to normal operation from a power loss as a result of this configuration.
Note: When the appliance plugged into the dryer socket is on and in standby mode, (like always-on appliances such as, Water heater, EV charger), it will not cause the EV socket to lose power. Only when it is actively in use, would the EV socket lose power.
