NAVIEN TECHNICAL DIRECTOR SEAN KELEHER HIGHLIGHTS WHY INSTALLERS SHOULD EDUCATE THEIR CUSTOMERS ON THE IMPORTANCE OF PRIORITISING HOT WATER DELIVERY IN THEIR HOMES… Making hot water delivery a priority
For homeowners, heating systems can be a daunting field - and one in which they typically have little expertise. The sheer size and scale of the range of boilers now available mean that a heating engineer’s customers increasingly see them as not just an installer, but also a consultant. In the space of a couple of decades, the conversation has changed from the simple ‘can you fit my new boiler?’ to ‘what kind of boiler is right for my home?’. THE RIGHT TECHNOLOGY In the past, for larger domestic properties or the increasingly prevalent multi- occupancy homes where adult children are yet to leave the nest, installers have traditionally favoured system boilers. This is because, historically, combi boilers servicing multiple bathrooms would
have resulted in low flow rates and delays in delivering enough hot water to meet increased demand. However, new technology can now meet the increasing demands of end-users who expect hot water on tap. Hot water recirculation systems can make combi boilers viable for these busier homes and they not only provide more comfort and convenience – but they can also help homeowners save money. Combi boilers with hot water recirculation can be a practical choice for larger homes. Also known as secondary return systems, they create a hot water loop, providing near-instant hot water to every outlet regardless of its location or the time of day. HOW IT WORKS Let’s go into a little more detail, taking as an example the Navien NCB700 ON Combi
