Saving made easy: How to drastically reduce your hot water costs!

Due to rising energy prices, hot water consumption is increasingly becoming a significant cost factor for households. According to information from Cosmo Hot water is the second highest household expense after heating costs. An average two-person household needs around 90 liters of hot water every day, which can result in monthly costs of between 20 and 60 euros. For older boiler systems, these costs can be even higher.

The type of hot water heating has a significant influence on the amount of expenditure. Simple saving measures such as shorter shower times and careful use of hot water when washing hands or washing dishes can help to reduce costs significantly. The use of single-lever mixers, which are more economical and user-friendly, is recommended. Economy shower heads that limit the water flow to around six liters per minute also contribute to savings. For comparison: a full bath uses between 120 and 150 liters of hot water, while a five-minute shower requires a maximum of 50 liters.

Efficient hot water preparation and temperature optimization

The recommended hot water temperature is between 50 and 60 degrees Celsius. This not only helps save energy costs, but also prevents the formation of Legionella. Switching to modern hot water heating systems is particularly beneficial in terms of climate protection as it reduces dependence on fossil fuels. Domestic water heat pumps and the integration of solar power are promising approaches here.

Replacing outdated boiler systems with modern electric storage systems can bring significant savings. Models like the EWH Digital from Austria Email, which have WiFi connectivity and app control, are particularly advanced. In ECO+ mode, the maximum temperature can be reduced from 65 to 58 degrees Celsius, saving up to 15 percent energy. In addition, the domestic water heat pump uses the ambient air to heat water and only requires a small amount of electricity.

Practical tips and recommendations

To get the most out of your hot water, it is important to choose the right boiler setting. This should be between 50 and 60 degrees Celsius to minimize energy loss. In general, a storage tank with 80-100 liters is sufficient for 1-2 people, while models with 120-150 liters are recommended for 3-4 people. By combining various savings measures, hot water costs can be reduced by up to 70 percent.

It is also helpful to know that not all energy-saving shower heads are compatible with hydraulic water heaters. These usually switch on at a flow of at least 8 liters of water per minute. If the flow is being tested with a flow restrictor, an economy shower head may be able to be used. In areas with high lime content, low flow volume fittings should be considered to use water more efficiently. Energy-saving hand basin faucets can only flow cold water at the center setting.

In the brochure “Saving Energy in the Household” from Federal Environment Agency You will also find tips on selecting and using efficient electrical appliances economically. Especially in view of the high costs and the negative impact on the climate, a conscious use of energy is essential. Households can further reduce their expenses by using energy-saving devices and conscious use of light sources.

The right combination of modern technology and conscious consumption decisions can make a significant contribution to saving money and energy in everyday life. By implementing these individual measures, not only financial benefits can be expected, but also a significant contribution to climate protection.
