You don't, electric water heaters are not meant to be converted.
There are small water heaters that run on 110 volts. However if yours is a large 240 volt heater and you only have 110 volts going to it, then it is fused and one on the fuses has blown in the service panel.
110-120 degrees Fahrenheit.
yes
It will not work. It will work, but you will only receive 25% of the rated output of the tank. A 3000 watt heater will only product 750 watts at 110 volts.
110-120 degrees for domestic hot.
110 into a decimal? = 110.0
110% = 110/100 = 11/10
Hardware store, home improvement center, or plumbing supply house.
Yes they do. The heaters are either 110 or 220. And the elements are usually universal.
To convert 110% to decimal divide by 100: 110% ÷ 100 = 1.1
A standard domestic water heater in a house, apartment, etc will need 220 Volts AC. They have two heating elements upper and lower and each is 110 VAC hence the 220 Volt supply. Make sure it has a dedicated circuit and a disconnect on the wall above and beside water heater.
No mixing valve is needed for either one. Set water heater at desired temperature. Both are usually pre-set from factory at normal 110-120 deg.
