Inside heated homes or apartments, this may be all you need to maintain proper fermentation temperatures.

What happens if you ferment beer too warm?

At higher temperatures, yeast grows more quickly, and fermentation is more vigorous. This causes the yeast to create by-products which spoil the flavour of the beer. … The most common by-products generated when you ferment beer too warm are esters and fusel alcohols.
