Electric Water Heating
Understanding the advantages of instantaneous hot water
Nick Mawby, Category Manager for Water at Redringdiscusses the
opportunities that instantaneous hot water solutions offer electrical
wholesalers by outlining the advantages for electricians and end users.
and the energy landscape have changed and alternatives to gas are increasingly sought due to a number of reasons. Thanks to advances in technology, electric heating and more specifically instantaneous water heating provides an extremely efficient, future proof solution that has the potential to revolutionise the way the UK generates its hot water. According to research undertaken by the
H
Redring Xpelair Group (RXG) a staggering 18 billion litres of water a day is wasted in the developed world along with 3,400 terajoules of energy, just through water being heated and then not used for its intended purpose. Wastage that Redring believes can be avoided through point of use, instantaneous water heating solutions.
The benefits are clear Instantaneous hot water solutions are available
for hand washing, water boiling for drinks, powering showers or sinks. Therefore when selling these types of products, the key
istorically, gas has been the most popular fuel source for space and water heating. However, the market
advantages to highlight is that they deliver hot water… lWhere it is needed lWhen it is needed lHow it is needed …all factors that help to reduce water and
energy usage, making them highly efficient and cost effective to use. Instantaneous water heaters only require a cold water mains feed to enable them to heat the water at point of use. This means that it is possible to fit them just about anywhere in a property or building, without the need for the installation of expensive and often time consuming hot water pipes.
Thinking about the pipework, many people
overlook the energy that is wasted in heating up long pipe runs when hot water is delivered from elsewhere (e.g. a central boiler) but with an instant point of use solution this is not an issue. There is also no delay waiting for cold ‘slugs’ of water to drain through before the water being heated by a boiler reaches the point of use. As the name suggests, hot water is delivered instantly which means there is no requirement to store hot water resulting in no standing heat losses. Also the heating and water flow starts
when the appliance is turned on and stops the moment it is switched off, helping to combat the problem of wasted water and energy highlighted as an issue in the RXG research.
A valid alternative to gas As the trend to extend domestic properties continues, homeowners are finding that SAP and water regulations are becoming a stumbling block when it comes to additional bathrooms. Point of use electric water heating provides an easy alternative that meets current regulations as well as helping avoid costly installation costs whilst increasing energy efficiency. A win-win outcome. For projects that involve multi-floor properties such as apartment and office blocks it is worth noting that current legislation may prohibit the use of gas in tall buildings so again point of use electric heating is the ideal alternative in this situation. Also, Point of Use electric water heating can
provide landlords with a simple solution that reduces installation, refurbishment and maintenance costs and complications as they don't require annual gas safety inspections or carbon monoxide monitoring.
