Instantly hot without wasting a drop - domestic hot water pumps
Get instant hot water at your fingertips
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?
It can take up to 30 seconds for water to run hot, depending on how far it has to travel across our homes, which could equate to approximately 3 litres of wasted water.
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 centralised 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 and ensures that hot water is immediately available without having to wait long or waste precious drinking water.
Its main task is to continuously circulate the hot water through the pipes to ensure immediate availability at every tap in the house.
How does a hot water circulation pump work?
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 continuously circulates the water within the pipe system, ensuring a consistent temperature throughout. This keeps the water constantly in motion, preventing it from cooling down.
Modern circulation pumps have various features to minimise energy consumption. An integrated thermostat regulates the pump's power according to the desired water temperature. This prevents the pump from running unnecessarily and wasting energy. 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.

How much energy does a hot water circulating pump use?
Hot water circulating pumps provide near-instantaneous hot water, minimising the waiting time and ensuring hot water is readily available when needed. This efficient delivery of hot water not only saves time and energy but also eliminates water wastage that typically occurs while waiting for hot water. Additionally, these pumps consume 60-75% less electricity than traditional hot water systems. By reducing both energy consumption and water wastage, these pumps are an eco-friendly choice for households. Installing a water circulating pump allows you to enjoy the convenience of instant hot water while minimising your environmental impact.
