BREWING SYSTEM REQUIREMENTS
We aim for EINBREW 3V2P to take care of electrical control for you, leaving you to concentrate on
designing and building your brewing system!
Constructing your own Electric Brewery is beyond the scope of these user instructions, and there are
a number of great guides out there that’ll help you achieve this. There are also a number of
performance and safety issues to consider when specifying and putting together your brewery.
However, for EINBREW 3V2P to work effectively, there are some areas to consider.
•Your heating elements must be appropriately sized for the amount of wort you’re trying to
heat/produce, whilst meeting the maximum EINBREW 3V2P power restrictions. If the heating
elements are too small, it may take a long time to increase the temperature of the wort as you
go through the brewing process, especially when boiling. In the worst case, you may be unable
to maintain your target temperature at all due to losses. You can also improve system
performance by ensuring that you keep a lid on your vessels when brewing, and insulating the
vessels. Elements that are too large may result in scorched wort, or considerable temperature
overshoot and oscillation during heating.
•EINBREW 3V2P supports one heating element for the Hot Liquor Tank, and one heating element
in the Boil Kettle, each up to 15A. This can only be used consecutively, not concurrently. For the
Hot Liquor Tank, the element can be directly in the vessel, or you can use an external heating
element through which wort is pumped around.
•Your system pump must be sufficiently powerful for the task –importantly, if using RIMS the
water flow must be able to remove heat from the in-circuit heating element at a sufficient rate,
or you may encounter issues where the water is e.g. boiling at the heater itself and much cooler
elsewhere. The pumps must also be rated for use at the operating temperature –it is worth
noting that many pumps will not operate correctly at 100C (boiling) due to cavitation. You
ideally want the temperature throughout the system to be as equal as possible, helping to
reduce temperature overshoot and oscillation. In the worst case, you could encounter
equipment damage or scorched wort. Similarly, the pump must be powerful enough to
continuously recirculate the wort through your mash without sticking, if relevant. The amount of
flow required can also vary depending on the type of grain and crush quality used.
•It is important that you do use pumps in your system where feasible, as if the volume of water is
not well mixed, the accuracy and quality of the control system will degrade.
•Ensure that your system interconnector pipes are of sufficient diameter to let through enough
flow, and is rated for use at the operating temperature. Make sure you test the system with the
pumps running and cold water after installation, to ensure there’s no leaks – these could be
dangerous when working with heated wort!
•Ensure that you have added sufficient filtering to the pump inlet –otherwise, you may encounter
clogging or flow restrictions after adding grain due to debris or grain in the fluid path/circuit. The
same applies if you intend to e.g. recirculate after hops have been added.
