Zumbi Steffens, eu pensava muito em usar uma versão compacta assim para chuveiros externos.

Viu que este termina com um vidro por cima da moldura? O vidro deve colaborar bastante, ele deixa a luz entrar para aquecer o tubo e prende o calor lá dentro, com certeza aumenta a eficiência

1/4/x50ft of black poly pipe much more efficient and cheaper.

I’m going to try this for my pool, can’t see why it wouldn’t work to help heat it, much easier than the bubble cover. Great idea!
