What's Needed for a successful Home Brewery

Most fully electric home breweries are based on a 5500 Watt water heating element for the brew kettle, a 5500 Watt water heater element for the hot liqour tank and a 1650 Watt to 5500 Watt water heating element for the mash tun or RIMS tube. Add all of these together and you could easily be at 16500 Watts just for heat and to run all three of these at once would require 68.5 Amps at 240 VAC.

But as shown in the picture above, you really only need one of these elements on at a time.

One 5500 Watt heating element only draws 22.9 Amps, making an existing 30 Amp dryer outlet or a new install dryer type outlet the ideal power source for an Electric Home brewery. The 7.1 Amps left over leaves plenty of room for other accessories like electric pumps and electric valves.

Step 1: Voltages Delivered to your House

The main utility power feed to your line transformer is usually around 7200 Volts AC. Your line transformer drops this high voltage down to two 120V voltages that are connected in series. The connection between the two is called a center tap and the center tap is connected to earth ground with a metal stake that's hammered into the ground.

Voltage is a measurement from one location to another that have a common electrical connection. For example a common flashlight battery is 1.5 volts - that's the measurement from one end of the battery to the other end of the battery. But if you were to measure from the top of one flashlight battery to the top of another flashlight battery you would not read any voltage because they are not connected together. Line the batteries up end to end & facing the same way and measure the voltage from one end to the other. You will measure 3 Volts because 1.5 Volts + 1.5 Volts = 3 Volts. This is called a series connection - the two batteries are connected in series.

The power connection to your house is no different. The voltage from the center - earth ground to either power lead coming off your transformer is 120 VAC but just like the battery example I showed earler, the voltage across the two in series, the two outside wires is 240 VAC.
