One of the more pleasant looking tanks on the market if that is important to you, this option from Hyco may be small, but it certainly competes with ones twice the size.
Great if you are placing in a room with no hot water system, water takes forever to reach your sink or want to go electric. This tank can be placed under any sink for low-demand hand washing or dishwashing purposes.
There is a temperature control dial so you can perfect it for the task at hand. A neon power light will let you know when its services are being used. It reaches a temperature up to 75 degrees, which is perfectly suitable for the vast majority of needs.
A 1.5m power cable is generous and comes pre-wired for easier installation. If you are rather knowledgeable regarding DIY and plumbing, you may even be able to give it a go yourself. Either mount it to a wall or leave it floor standing if it’s under a sink.
It is PX4 waterproof rated, and the inner is porcelain enamel-lined, so safe from corrosion and rust over time. You will be able to get around 2 L of hot water from it before it starts going tepid, and it takes about 12 minutes to fully heat again. Ideal for sinks or hand washing in lower demand areas, and it’ll also work with mixer taps.
