  • Grundfos energy saving pumps

    When it comes to saving energy, you may not think that pumps have very much to contribute. But you might be surprised to learn that pumps actually account for around 10% of all electricity consumption worldwide.

    Grundfos pumps

    Where are all these pumps? If you think about it, they’re an essential part of modern life, from circulating water in central heating systems to powering showers and running pool filters. There are more pumps around than most people realise, and most homes contain at least one.

    Designed with energy efficiency in mind

    That means that there’s considerable potential for saving energy by choosing the right type of pump. Grundfos Pumps is one of the leading manufacturers and designs its pumps with energy-efficiency in mind.

    Many individuals and businesses buy a bigger pump than they need, and they leave it running for longer than necessary. There’s therefore potential to save energy by specifying the right equipment and controlling it properly.

    Grundfos Pumps offer many of their models with automatic speed adjustment, which means they only work as hard as they need to. For things such as showers, the pump doesn’t need to run all the time - only when the shower is in use. This has other benefits too, as pumps - even those such as the Grundfos Amazon shower pump, which is designed for quiet operation - always generate some noise when running. So only having it operate when required makes for a quieter environment.

    Choosing the right Grundfos pump

    In areas with poor mains water pressure, a pump may be required in order to get a decent flow at the taps. By specifying the correct model from the range of Grundfos Pumps, it’s possible to eliminate water-flow problems but still minimise energy consumption. Again, a key element is control - only running the pump when it’s required rather than having it active all the time.

    For commercial users, Grundfos Pumps have tools to help users carry out an energy check or pump audit to ensure they’re using the right pumps for their needs. It may be the case that by switching to a smaller pump, users are able to save energy and still shift the same amount of water effectively.

  • The history of central heating: From 15AD to 2015


    central heating pumps

    Today we take our central heating systems for granted, but it wasn’t always like that. Our modern systems with efficient boilers and central heating pumps are designed to keep our properties as warm as we like, but they have developed substantially from the initial models. Here we take a look at the development of central heating, from the early Roman methods through to the systems we benefit from today.


    Early Heating Methods

    The Romans were the first to invent any form of heating as far back as 15AD. Hypocaust, as the system was called, used a furnace to create hot air that then went along channels under the floor and pipes within the walls to generate heat. This type of heating created better living conditions and was the start of the development of central heating.


    19th-Century Developments

    Once the Roman Empire collapsed, the use of central heating largely came to an end, and homes generated heat through the use of individual fireplaces. Over the next thousand years, there was very little central heating in existence. It wasn’t until the 1830s that mass-produced systems that used steam were introduced.


    These were initially created by Angier March Perkins, who was an American based in the UK. His first customer was the then Governor of the Bank of England, who wanted to keep his home warm to enable him to grow grapes.


    Radiators were first introduced in Russia in 1855, and this is when we see the start of central heating as we know it today. Thomas Edison then went on to invent the electric heater in 1883, and by 1896 there were solar water heaters in existence.


    Central Heating Pumps in the 20th Century

    There were further developments in central heating systems during the middle of the 20th century. Robert C Webber came up with a direct exchange ground source pump towards the end of the 1940s.


    Central heating started to be installed within new homes from the mid-20th century. Today very few homes don’t have any form of central heating. Our modern systems combine radiators, a boiler and central heating pumps. Radiators are designed as a feature of the room now rather than a bulky appliance, and there are designer, slim and vertical styles to choose from.


    21st-Century Heating

    We now benefit from far more advanced heating systems than those early Roman models. The technology that we use within central heating pumps and other components allows the system to run as efficiently and effectively as possible. This enables us to have lovely warm homes while at the same time helping to keep our energy usage in check.


    Engineers are constantly looking at ways of improving our central heating systems to make them more efficient and cheaper. We are now seeing the use of more renewable sources of energy, such as solar and wind. They are considered a more viable option than they were a few years ago, and this is an area that will see significant changes in the coming years.
