Antifreeze Water Bowls
Heated 24 V drinking bowls - how do they work?
Heating drinking water using the trough is so easy! You only need at least one heatable trough, a thermostat
and a transformer (as 24-volt operation).
Which transformer for how many bowls? Simple! If you only want to operate a drinking bowl with 80 Watt of
power, then a 100 VA transformer will suffice. If you also want to connect a 24 V
heating cable, simply add the power consumption (= Wattage) of
the cable and this gives you the minimum power required for the
transformer. Do not measure the transformer‘s power too
precisely in order to have a buffer for extensions.

When choosing transformers, ensure that you take
account of the power loss through the feed cable. A
sample calculation and a table containing the power
losses can be found in this catalogue.
