Before delving into the world of 21st-century water heaters, there are some factors you have to consider. To have an optimum experience with under sink tankless water heaters, each of these factors is crucial. So, before purchasing any of these water heaters, you have to make a calculated decision.
The Two Types of Under Sink Heaters
Firstly, you have to be aware that there are two kinds of under the sink water heaters. It could come with a tank like the Bosch Tronic mini tank water heater, or it could be tankless such as the Stiebel Eltron. Tankless water heaters are created in such a way as to heat water fast, so a storage tank is not needed. These tankless water heaters take lesser physical space and can easily be mounted.
However, the mini-tank in the other kind serves as a reservoir. The tank ensures that the user has hot water in the few seconds instead of waiting for incoming hot water. The tankless model does not have a storage tank, but it provides an unlimited supply of heated water. On the other hand, the tank-type is limited by the capacity of the tank.
Before you purchase an under-sink water heater, you should be equipped with an awareness of the water you intend consuming. When you choose your water heater, you should consider how you want to use it and where.
Do you intend using it on boats, kitchen sinks, bathrooms or in commercial areas? For instance;
If you have considered purchasing a tankless water heater, you should be aware of its limitations. As they do not rely on reserved water, there is a targeted amount of water they can heat up which is the GPM rating.
The higher the GPM rating is, the more the amount of hot water delivered by the unit. For under sink water heaters, the size you purchase should depend on the number of people in the area where it will be used (e.g., the home).
Very important, you need to consider the size of the under sink water heater carefully. Lightweight units are generally preferable as they can easily fit into small spaces. But this depends on how you intend to use an appliance; if you plan on using the heater for the kitchen sink, shower and washer simultaneously, a bigger unit might be a better choice.
Good water heaters should use less water and less fuel (electricity or gas). To help your wallet and the planet, it is wise to be energy-smart. So, purchasing a water heater that uses up everything is not a good option.
You should check out reviews to ensure that the unit can be easily installed. There are some such as the Ariston GL2.5 reviewed in this best under sink tankless water review that can be installed singlehandedly.
