NRG Zone System Explanation

The Differences between NRGZone and other Heating System Manifolds on the Market We are constantly being asked if NRGZone is just another manifold like so many others on the market including Low Loss Headers, Neutraliser's and the manifold that I were made over 20 years ago, to deal with standard systems back then. I thought I'd put the differences here to answer those questions once and for all. The diagrams here show how an NRGZone and the types could be used to connect boilers and zones and to describe what happens inside the unit's when they are working in their uniquely patented way. One of the crucial features of the NRG Zone unit is that it has three distinct chambers, the top one is where boiler flows and zone flows are attached, the middle chamber is a bypass for any water that is not being used by the zones to return to a standard temperature boiler like a conventional oil or gas boiler or a solid fuel stove. The bottom chamber in the NRGZone is completely different to any other unit as it collects the return water coming back from zones and allows that coldest system water to be drawn back to condensing boilers or heat pumps making them much more efficient and operate at their most energy cost effectiveness. Both condensing boilers and heat pumps completely rely on their return temperature being as cold as possible for them to work as efficiently as they are designed to do. This feature is not available in any other manifold on the market. The additional third socket on the left and right hand side of the NRGZone also adds great versatility to how it might be used for example 2 boilers might be connected at the left side with the second boiler flow entering the manifold through the top left-hand socket and this would allow all of the other sockets to be used for zones. It would be quite easy using the NRGZone 5 manifold shown to have 6 zones as well as the two boilers where two zone flows could be taken from one flow port and the returns could be connected similarly. Price-wise, the NRGZone 4, a lager but still standard sized unit then the NRGZone 4 shown can handle two boilers and 5 zones as well as all typical ancillary equipment. Check for yourself what it would cost for any other manifold to do that and I think you might be pleasantly surprised as it could be as much as €100 material cost in the difference as well as a substantial increase in installation costs. There are many other features in the NRGZone that would take too long to describe here but to list some examples would be; fully insulated, built-in air separation, larger internal volume for a better buffer type facility and the ability to connect an expansion and cold feed on the top right-hand pair of connections directly to the manifold making open systems much easier and economical to install. All of the other manifolds in the marketplace and including the huge range of Low Loss Headers do not work well with condensing boilers because the returning zone water is always mixed with the hot unused primary flow water and this is certainly the case with heat pump installations. This is a different era in the area of central heating, the cost of fuel has changed all of that, as well as customers’ expectations and their interest in the environment and fuel savings and of course present building regulations and the further regulations on the way. There was a need for NRGZone to satisfy all those requirements and to be as cost competitive as it is. We are all aware that there has been a sudden upsurge in gimmicks appearing on the market that any competent plumber would naturally know do not work. Many believe that those gimmicks have entered the marketplace because many installers are taking less and less interest in the technical side of the trades. We believe that it is not just a matter of interest to understand how best systems should work but that it is a responsibility that customers can demand from their installers. But most importantly the quality of the systems and the workmanship that an installer leaves behind will decide the quality of his reputation and the quantity of his work in the future. We believe that NRGZone will continue to make problem-free systems that installers can not only enjoy working on but can profit from knowing that they will not have system call-backs if they follow the simple instructions and take advantage of our free technical support.
