HOT WATER

INSTANTLY HOT WATER

Most people appreciate the pleasure of instant hot water. A hot water recirculation solution ensures that you never have to wait for hot water in showers and taps, and thereby reduces the water wasted while waiting for the water to reach the desired temperature. A hot water re-circulation pump is a pump designed to circulate domestic hot water within the hot water distribution system. The hot water re-circulation pump transfers hot water from the water heater to the tapping points sending cooled water back to the water heater to reheat insuring instantly hot water.

WHAT A WASTE

Every year, a typical family of three living in a household fitted with a conventional one string plumbing system pours up to 16,000 litres of clean water straight down the drain - for no good reason at all. Every time they turn on a hot water tap or a shower, they wait an average of 60 seconds for the water to run hot. This wastes approximately 1,5 decilitres of water per second.

Using hot water five times a day over the course of a year results in a total waiting time of over one whole day.*

It's a burden not only on your pocket and your time, but also on the environment.

*The figures are based on a report by Dr. Ing. Hugo Feurich VDI and calculated as a typical household of three persons each wasting 15 litres of clean water on waiting for hot water per day.

SUDDENLY, THE WORD 'WASTEWATER' GAINS A WHOLE NEW MEANING!

Talk of global warming is usually in relation to global temperature change, melting ice caps or when catastrophic weather events occur. Yet one of the greatest challenges we face over the next few years will be the widespread shortage of drinking water in many parts of the world.

Waiting on hot water is not only a waste of time and money; it's also a waste of nature's finite resources.

SUPERIOR COMFORT AND ENERGY EFFICIENCY

Instantly hot water has been the popular characteristic of the Grundfos' COMFORT pump. Now, we take the solution one step further with the introduction of the new high efficient COMFORT PM pump with AUTOADAPT. The intelligent AUTOADAPT function learns the consumption pattern of the household and adapts the domestic hot water supply to it. Tapping data is stored in an integrated calendar each time a hot water tapping occurs. This is done by means of the external sensor that detects each time hot water is tapped. The calendar stores 14 days of information and is continuously updated. In so doing the demand for circulation in-between tappings is reduced to an average running time of 3 hours resulting in electrical savings of up to 96% and heat energy savings of up to 48% compared to a conventional hot water recirculation pump.
