Pros and cons of connecting the dishwasher to hot water

Dishwashers are relatively new to the usual way of life of most of our fellow citizens, so questions related to their use still arise quite often.

Among the most common are worth noting as commonplace, for example, about how to load the dishes, and more global, for example, whether it is possible to connect the dishwasher to the hot water system. This question is connected with the fact that the cost of electricity increases, and there is always hot water in the faucet. That is why people think about why, and why waste light on water heating in the dishwasher, if it is possible, just connect it immediately to hot water and avoid unnecessary costs.

User comments on this topic are often found on the network, so we decided to devote today's material to the question of whether it is possible to connect a dishwasher to a hot water system, and not traditionally to a cold one.

After interviewing experts, we concluded that it would not be possible to give a clear and unambiguous answer “yes” or “no”, because there are conflicting recommendations, even from manufacturers of dishwashers. Some respondents claim that it is more economical, while others say that it is better for the appliance when the owners still connect the dishwasher using cold water.

Traditional connection of the dishwasher

Most dishwashers that are sold all over the world are designed to fill the hose with cold water and are equipped with instructions that the device needs to be connected to a cold water supply.

Most people follow the instructions and connect their dishwasher to a cold water source, and they work fine.

Question of connecting to hot water

Many dishwashers can be connected to a source of warm water. However, it is important to remember that this must be indicated in the instruction book and you must follow some

rules. However, if you decide to connect the dishwasher to hot meals, you must use a special pouring hose that is designed for use with such water.

You should understand that this is not just a meaningless requirement. By connecting a cold water hose to hot water, you are at high risk.

Remember that water supply hoses are always marked in red or blue, or with a red stripe or a blue stripe. This is done so that the consumer can recognize the destination. If this is pure marketing, then it is still justified.

It is reasonable to expect that the materials have separate requirements for carrying hot and cold water, they are sufficiently different to require specialized hoses.

Pros and cons of connecting a dishwasher to hot water.

• Pros for

Presumably this saves energy because dishwashers wash dishes at high temperatures and also use high temperatures for the last rinse to help drying.

However, it is not entirely clear why under the condition that warm water is used, because washing is so much more efficient in this case, manufacturers rarely recommend using hot water to connect. On the contrary, the instructions state that cold water should be used for the connection.

• Arguments against

If the water is more than 60 degrees, it can damage the filtration system built into the dishwashers, so do not use very hot water if this is the case.

It is well known that water heating should only be set at 60 degrees in any case, which is the best indicator for water supply in most homes. If the water is much hotter, it is not only dangerously hot, but you cannot use it for anything without adding a lot of cold water.

The question arises, why then heat the water to such a high temperature, only to cool it with a cold source before it can be used. An exception to this rule may be relevant for people using solar energy to heat water, where it can heat up to higher temperatures at no extra cost.

However, the high temperature still remains a potentially dangerous factor and is relevant depending on the age and abilities of people who can use it.

Hot water sources cannot have the same water pressure as cold water, especially if it is supplied through a cylinder in a boiler. Hot water hoses are more prone to kinks and wrinkles, so if you connect a dishwasher, you will need to ensure that the hose is not under any kind of physical activity, because when the warm water passes through it, the hose may become softand burst.

Hot water can also “glue” food to the plates when washing for the first time, and complicate the cleaning process.

Dishwashers often have a wash cycle with a temperature of 50 degrees. If the inlet water temperature is already 60 degrees, this program may be compromised.
