In order not to use too much unnecessary energy for hot water circulation, in addition to an efficient pump model, switching regulation that is as economical as possible is important. In the following, we will show you what to look out for and what technical support options are available.
Set the switching times of a hot water circulation pump economically
Whether the circulation of warm drinking water in the house is set up out of obligation or simply for more comfort and hygienic safety - it always costs additional energy. How much is entirely up to the operator. And to a considerable extent. Depending on which method and which techniques are used, the annual cost of hot water circulation can go into the hundreds or remain on a low, double-digit and slightly dampered level.
The most important in economizing the hot water circulation are the following aspects:
- Energy-saving pump model
- Possibility for the regulated time circuit
- possibly even intelligent user adaptation of pump control
The basis: an efficient pump model
The half rent in the energy and cost-saving hot water circulation is the pump model. If you are still taking advantage in the years or even the gravity circulation method, you will charge high costs every year. Modern high-efficiency circulation pumps consume a fraction of what older models with more inefficient drive technology and possibly more significant signs of wear and tear - they often get by with only around 15 watts.
Let the pump pump only when necessary
In addition, it is already standard nowadays to only let a circulation pump work when hot water is actually being drawn off. This saves unnecessary operating energy and, if required, hot water is still available immediately. This can easily be done with a simple timer. The pump can then ideally set this in motion as rarely as possible during the day, for example once in the morning and once in the evening, before the peak times for hot water consumption. The concentrated, time-switched phase operation with very regular daily routines is particularly worthwhile.
In times when artificial intelligence is on the advance, circulation pumps or upstream controllers that are equipped with learning technology are increasingly coming onto the market. They register the consumer's hot water usage habits and automatically adjust to them by starting the pump in good time before the usual tapping time. What is particularly convenient is that the pump not only adapts once, but also faithfully follows the consumer when habits change.
