Hot water with shorter waiting times – domestic hot water circulation pumps
Enjoy hot water sooner at the tap
We’re all used to running the taps and showers in our homes and having to wait for our water to run hot. Most people have come to accept that this is normal, but does it worry you how much water you’re wasting in the meantime and how this affects your water bill?
Depending on the distance between the water heater and the tap, it can take up to 30 seconds for hot water to arrive. During this time, approximately three litres of water may flow unused.
Did you know that by installing a hot water circulating pump this time is greatly reduced as hot water is pumped to your taps quickly and efficiently, meaning that you’ll reduce the amount of water you waste and improve the comfort of your home at the same time?

What is a hot water circulation pump?
Common centralized hot water systems are designed in a way that cold water in the pipes needs to be drained before freshly heated water reaches the tap. As water sometimes has to flow through long pipelines before reaching the desired outlet, patience is often required.
This is where a hot water circulation pump comes into play: It is an electrically operated pump that is integrated into the hot water system of a house
Its main task is to circulate hot water through the pipework, helping to make it available more quickly at the connected taps.
How it operates
The process starts at the water heater. Cold water is heated and flows to the point of use, such as the sink or shower. When you turn off your tap or shower, the circulation pump moves the warm water in the pipes back to the hot water storage tank. Additionally, the pump circulates the water through the pipe system, helping to maintain a more consistent temperature. This keeps the water constantly in motion, preventing it from cooling down.
Modern circulation pumps may include features such as timers or temperature controls that allow the system to operate according to demand. An integrated thermostat can adjust the pump’s operation according to the water temperature. This can reduce unnecessary pump operation and the associated energy use. Additionally, many circulation pumps are equipped with programmable timers that activate the pump only during specific times of the day, such as mornings and evenings when the demand for hot water is higher.

Running the tap after vacation is important to flush out stagnant water from the pipes and reduce the risk of bacterial growth, such as legionella. Stagnant water in the pipes during your absence can promote the growth of bacteria.
By running the tap for a few minutes, fresh water is flushed into the pipes, removing possible contaminants.It is advisable to take this measure to improve water quality and reduce the risk of health issues when using the water upon your return. Make sure the hot water temperature in your hot water system is not below 55 degrees Celsius, as temperatures below this level may promote the growth of Legionella.
