The winter 2009/10 in Europe was a long one and very, very cold.  The temperatures dropped to minus 20° Celsius and even more. And the colder the winter is the more energy is needed.

As in the page Inherent Energy already described a lot of energy is being wasted. The colder the outside temperatures the more energy is wasted. Little gadgets, like a Heat Exchanger, could prevent this waste of energy.

This is not just a waste of energy but also a waste of your money!

In the cold winter the water arriving at the building is about plus 4°  Celsius.

The water in the water tank of the toilet heats up to the surrounding temperature of about  plus 20°  Celsius and even more.

The difference is 16°. This needs a lot of energy.

In the end the water is flushed into the sewage where the heat disperses and melts the snow on the manhole cover.

A Heat Exchanger at the outflow to the sewage could be a good investment.

Since pictures say more than 1000 words, let the picture talk.

The pictures were taken 2009/10 in Belgium and Germany.

    Helpful piece of writing. I can consider it be the case of course not normally. I usually don’t publish though I would like to chime in this time and let you know I appreciate the blog.

    I’ve recently started a blog, the information you provide on this site has helped me tremendously. Thank you for all of your time & work.

    Thanks for sharing, I just wanted to let you know that your blog doesnt show up perfectly on the blackberry browser but I am probably still in a minority of users.

    Hello, I found this by accident while doing some research on a different topic. As is the case for me. I found your posts informative which is highly refreshing. Keep up the great work.

    nice, but i think for example the inherent Energy Saving of historic and old buildings have a very interesting things, Many historic buildings have energy saving physical features and devices that contribute to good thermal performance.

    Older buildings were found to use less energy for heating and cooling and hence probably require fewerweatherization improvements. They use less energy because they were built with a well-developed sense of physical comfort and because they maximized the natural

    I found this post while surfing the net downloads. Thanks for sharing will be sure to follow this blog regularly and will email this article to my friends.

    Energy efficiency in industry contributes to decoupling economic growth and environmental impact while reducing industrial energy intensity and improving competitiveness. Industry is responsible for more than one third of global primary energy consumption and energy-related carbon dioxide emissions. Industrial energy use is estimated to grow at an annual rate of between 1.8 per cent and 3.1 per cent over the next 25 years. In developing countries, the portion of energy supply (excluding transport) required for industry can be up to 50 per cent. This often creates tension between economic development goals and constrained energy supply.

    The integration of Photovoltaics in the fabric of the building will not only ensure that the cost of electricity will be lower but that resulting carbon dioxide emissions will also be reduced.

    solar system will always compliment an existing boiler, think of the solar panels doing the hard work taking the water temperature upto 45 degrees in winter and the gas boiler taking the water the last bit to 60 degrees. Solar Thermal Solar thermal / solar water heating system uses heat energy from the sun to generate hot water for heating applications where the demand for hot water is significant such as showers and swimming baths. A solar thermal system depending on the size of the installation can provide up to 70% of your total annual hot water requirement.
