The Powerblanket range has obviously been designed and manufactured with quality and care in mind – the materials are beautiful, look like they will stand up to repeated use and even the instructions are clearly written. This model is a good start for bucket electric blankets. I use them to keep the natural soaps, waxes and dermatological products I make at a constant temperature. I've noticed significantly less energy consumption as I'm not heating things up, waiting for them to cool down and wasting energy. I can also do a lot more in less time. So if you need constant heat for a keg this looks like a very energy efficient solution. The pace seems incredibly stable - super impressed.
