Heat Pumps for Hot Water Explained

As a pre-installation, the Heat pump for hot water circulation is responsible for ensuring that as little cold water as possible is wasted. For example, when you are about to take a shower might have to wait until the water has warmed up. The same applies to the use of the tap in the morning hours. 

Because the circulation pump supplies the warm water, there are advantages in terms of economy and a more conscious use of drinking water, which in turn protects the environment.

Why are Heat Pumps for Hot Water necessary?

The heat pump tank addresses a common problem in central water heating systems. These are set in such a way that cold water first has to flow completely out of the pipe before new, warm water can be processed through it. In theory, this should prevent water from being wasted or unnecessarily heated. In practice, however, this has disadvantages. Because, especially in the morning hours, it sometimes takes longer for water to actually come out of the pipe at the desired temperature. Therefore you have to let the shower run a little ahead of time or wait until the tap no longer delivers cold water.

Can Heat Pumps Be Integrated ?

The circulation pump for hot water addresses this issue and can be integrated as a supplement. It then ensures that the treated water circulates continuously in the pipe system and that warm water is available from the first drop. This eliminates the cost factor that arises from the unused cold drinking water, which protects both the wallet and the environment. Further advantages can be seen in terms of comfort. Because of course it saves a lot of time if you can take a shower instead of having to wait first.

How Does a Heat Pump Work ?

The pump is integrated as an additional installation, creating a circuit. A hydraulic balance of the system is absolutely necessary before installation. Otherwise the efficiency could suffer and the desired savings effect could not even occur. Several such pumps can also be installed in apartment buildings in order to meet the increased demand. In particular, this also helps to prevent undesirable irregularities and instead to ensure a really pleasant temperature from the first drop.

Cost & Energy Consumption of the Circulation Pump

Both acquisition costs and ongoing costs must be taken into account here. Depending on the model, the one-time purchase costs are around 120 to 150 euros. In view of the fact that the pump can then be used for years, the costs remain manageable. The running costs arise from the operation of the pump. Here, however, it must be taken into account that these are also created during hot water preparation and are consequently minimized and not increased by the circulation pump for hot water. Modern models promise about a saving of 30 euros a year, although this naturally depends on how often hot water is used.

Newly installed pumps normally consume around 10 to 30 watts

Newer models also have the advantage that they work with an intelligent pump control. The circulation in the circuit is therefore only driven when the temperature actually threatens to drop too much. If the circulation pump is not connected to the control, it can alternatively be controlled via an on-site timer. An additional check valve prevents gravity circulation and protects the pump from back flowing water. The insulation of the pipes therefore also plays a role. Newly installed pumps normally consume around 10 to 30 watts. With older installations, however, the consumption is much higher.
