Unironic poverty; These showers can be installed with minimum cost beyond running a line (usually parasiting a nearby electric outlet) and if they break, it can be easily replaced. Also, electricity is costly in Brazil, so running a themoacumulator even for a few hours could become prohibitively expensive, especially as many only use warm showers during the colder months.

Yes, but we're too poor and retarded.
