The 48-ounce reservoir is the best you can get in its price range. With this capacity, you will be able to make roughly six to eight cups of coffee in a single Brewing. This huge capacity speeds up the coffee brewing and saves you a lot of refilling time and energy.
Even the refilling process is quite simple. The water reservoir can be removed from the machine. To refill the water reservoir, you can simply remove the tank and refill it with water. You can also choose to refill it while it’s still attached, but that may cause some damage to the machine.
The water tank has a special and unique feature called ‘descaling’. The descaling feature will remove any scales in the water reservoir.
One of the major problems you may face with the water reservoirs is the scale build-up. Now, generally, when distilled water is stored, there won’t be any scale build up because of the absence of salts. However, the water we use and drink has a lot of salt in it.
Those salt may include calcium, sodium, potassium, etc. The Calcium salts create scales in the water tank when stored for a long time. These scales may be potentially harmful when present in the water. You will be safe from these harmful effects because of the descaling feature.

The power efficiency of the self-priming machines is lower than those of the normal machines. This can be an advantage to the environment. However, it takes more time to brew coffee after turning it on for the first time.
The water reservoir has a descale indicator, which basically indicates the level of the scale build-up in the reservoir. The scale build-up is not good for the water, and hence cleaning is a necessity once the scale reaches high in the indicator.
