Pros and cons of connecting the dishwasher to hot water

Dishwashers have recently become part of the everyday life of most of our fellow citizens, so questions related to their use still arise quite often.

Among the most common, it is worth noting as banal, for example, about how to load dishes, and more global, for example, is it possible to connect a dishwasher to a hot water system. This question is due to the fact that the cost of electricity increases, and there is always hot water in the tap. That is why people are thinking about why waste light on heating water in a dishwasher, if, perhaps, just connect it directly 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 came to the conclusion that it will 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 say it is more economical, while others say it is better for the appliance when the owners do connect the dishwasher using cold water.

Traditional dishwasher connection

Most dishwashers sold around the world are designed to fill the hose with cold water and have instructions for connecting the appliance to a cold water supply.

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

Hot water connection issue

Many dishwashers can be connected to a warm water supply. However, it is important to remember that this must be indicated in the instruction book and some rules must be followed.

However, if you decide to connect your dishwasher to hot water, you must use a dedicated fill hose that is designed for use with that water.

You must understand that this is not just a meaningless demand. There is a high risk of connecting a cold water hose to a hot water supply.

Remember that water hoses are always labeled red or blue, or with a red stripe or blue stripe. This is done so that the consumer can recognize the purpose. If this is pure marketing, then it is still valid.

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

Pros and cons of connecting the dishwasher to hot water

• Arguments for"

This presumably saves energy, as dishwashers wash dishes at high temperatures, and also feature high temperatures for the final rinse to aid drying.

However, it is not entirely clear why, given the use of warm water, because the sink is so much more effective in this case, manufacturers rarely recommend using hot water for connection. On the contrary, the instructions state that cold water must be used for the connection.

• Arguments against"

If the water is over 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 common knowledge that water heating should only be set to 60 degrees anyway, which is optimal for water supply in most homes. If the water is much hotter, not only is it dangerously hot, but you can't 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 be heated to higher temperatures at no additional cost.

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

Hot springs of water cannot have the same water pressure as cold springs, especially if it is supplied through a cylinder in the boiler. Hot water hoses are more prone to kinks and kinks, so if the dishwasher is connected, you will need to make sure that the hose is not under any physical stress, as the hose can become soft when warm water passes through it. and burst.

Hot water can also “stick” food to the plates during the first wash and complicate the cleaning process.

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