Best Boiling Water Taps – Buyer’s Guide
Boiling water taps are increasingly becoming a must-have for every kitchen and, after reading through our top five, we’re hoping that you can see why! However, if you’d like a little more information before purchasing a boiling water tap, here are some different criteria worth considering:
A Filter System
Though this is usually an additional advantage and by no means a requirement in a standard boiling water tap, it is definitely a feature that is worth considering. Not only does the addition of a filter system help to prolong the performance consistency of your boiling water tap, it will also help to reduce the chance of limescale forming if you live in a hard water area and keep unpleasant odours or tastes from forming in your drinking water.
Safety Features
In our opinion, this is one of the most important specifications that every boiling water tap should have. Luckily, many manufacturers have ensured that their boiling water taps are not only convenient and easy to use, but also completely safe to use, too.
Though the safety features will differ for each boiling tap, one of the most common types of safety precautions taken is by including a safety clip to prevent boiling water from being dispensed, or by requiring a specific lever to be pulled to activate the boiling water.
Tank Size
Another feature you might want to consider is the capacity of the tank. The size of the tank can vary from tap to tap, so it’s important to first decide how often you are going to be using it. If you plan on using your boiling hot water tap frequently, it might be worth going for a boiling water tap with a larger tank capacity. If you don’t plan on using it that often, though, a smaller one will suffice.
