Stepping into the shower in a hotel or a friend’s house is always a step into the unknown. Where is the ideal temperature for showering, how long does the water take to warm up? Surprised A lot of living comfort depends on the optimal water supply, which makes controlling it in your own home even more important. This control not only makes showering and washing up more pleasant, but also significantly saves hot water.
Hot water consumption accounts for a significant portion of household energy consumption. In this guide we present some tips with which you can save hot water and thus significantly reduce your costs.
1. An optimized hot water tank lays the foundation for savings
While some hot water storage tanks are tied to gas boilers, many modern storage tanks do not require an existing gas heater because they are not dependent on the heating system.
You can save a lot of hot water even on a small scale, but it’s best to lay a solid foundation to regulate the water balance in your home. With a efficient hot water tank a lot of wasted hot water can be reduced. This memory ideally has one strong thermal insulation and also does not give off the high temperature by heating up the fittings.
This is particularly important insulationsince the water is in a hot water tank permanently kept at a higher temperature – this prevents the proliferation of legionella, a type of bacteria in water. Without proper thermal insulation, energy must constantly be expended to reheat the water as the heat is released to the outside. However, high-quality modern storage systems have good insulation and consume energy not much power in regular standby modewhich is why the potential to save hot water with them is high.
Because unlike without additional devices, you have to have a hot water tank Don’t let the water run first and waituntil it finally heats up. In older, unrenovated homes this can take a considerable amount of time, using up a lot of unnecessary energy for showering, washing dishes or even simply washing your hands.
No matter whether with a gas boiler or other heating installation Costs of every wasted warm-up add up quickly. Modern storage systems can heat up immediately and in a very short time. But older models require a certain lead time. Older types of heating still incur additional costs Maintenance and repairs heating by an expert service provider. Modern devices require less maintenance.
Tip: Even if the passive heat output of the storage tank is very low, you should still adapt the size of the hot water storage tank as closely as possible to the size of the household and consumption.
2. Faucets become more efficient with little effort
A hot water tank is a major investment and takes a while to recoup the initial cost due to the lower electricity consumption compared to a tankless water heater. In contrast, there is several small productsthe effect of which may not be immediate, but is cheap to purchase – and also saves hot water in the long term.
Aerator
In many places the term “aerator” is used synonymously with aerator. Perlator is actually a registered trademark of the Neoperl group of companies.
A prime example of this is a water-saving one Aerator: Attached to the faucet, the small nozzle mixes air into the water jet, meaning the jet remains equally strong but uses less water.
The practical devices only cost a few euros and can significant savings in water consumption make this possible – with particularly water-saving models, over 5 liters less are consumed per minute!
An aerator is cheap and saves water; it only needs to be descaled occasionally.
This is particularly useful if surfaces need to be wetted, for example when washing dishes or washing hands. If you fill a bucket with water, you obviously have to wait a little longer until the bucket is full due to the lower output. It therefore makes sense to install aerators specifically on the taps that are used a lot for showering instead of filling up.
In addition to preventing constant dripping, what is beneficial for all hot water faucets in the house are Single lever mixer or one-handed fittings, i.e. taps, where Hot and cold water regulated by a lever become. If you have to mix the right temperature with two levers or knobs, a lot of water is lost until you find the desired heat every time. With a single-lever mixer, you can easily internalize the correct position of the lever.
Danger: While it seems practical to always leave the levers in the correct position, it is better, especially on the sink, to always turn them to the right to “cold”. This means you don’t heat up water unnecessarily when you don’t need it warm, and it’s a particularly easy way to save hot water.
3. An economical shower head does what the name promises
When it comes to tips for saving water, there is usually one tip at the top: Showering instead of bathing. And that is undoubtedly true Showering usually uses significantly less water than a full bath. Not letting the tub fill up too often is a much cheaper option. But there is still a lot that can be improved when it comes to showering itself.
A Economy shower head works similarly to a faucet aerator: this Water is mixed with air, which does not limit the showering experience in any way, but can reduce water consumption by more than half. Models can be particularly water-saving flow rate limit to 4-6 liters, while regular shower heads average 12-15 liters.
Saving shower heads are available for €20-30. It doesn’t take too long until you make up the money by saving hot water.
In addition to the product-related options, of course they also apply simple measuresthat more on Behavioral changes based: To reduce the shower time or turn off the shower while soapinghelps to reduce consumption without any additional purchases.
