Please remember that the current UK heat-wave is an aberration even though it's summer. abigt
If the average temperature in your location is
LESS than the temperature at which you wish to control the fermentation temperature of your brew, then there is no requirement for a fridge!
I normally ferment at +/-20*C so if I lived in Birmingham (I thank God that I don't
) I would only need to
HEAT my fridge to control fermentation temperature all year round.
A fridge is ideal for the purpose of fermenting because the insulation that is designed to stop the heat entering the space when it is in refrigeration service, is the same insulation that prevents the heat from escaping when using it as a Brew Fridge during cold weather.
The fluctuations outside of any fridge are kept at bay so that the interior of the fridge stays very stable
if the door is kept closed. Over an average summer day, the external temperature may fluctuate from +30*C to +15*C but the temperature inside the fridge may well stay to within 17*C to 19*C.

Fermenting at +20*C in Birmingham, you may
never need to cool down the FV, but you will definitely need a heater in the fridge for at least 10 months out of every year! :thumb:
