bottom also provides new opportunities. The Mixergy cylinder, for example, uses a pump to drive the hot water thermocline to accurately control water volume to an accuracy of 1 per cent, and it can also drive hot water to the absolute bottom of the cylinder. This ensures that complete pasteurisation of the cylinder takes place. Pasteurisation events are controlled by the tank, as is the stored water temperature. This ensures that cleansing cycles are carried out at suitable intervals, proactively managing the health of the domestic hot water system. This data is provided to housing providers in a smart intuitive dashboard. Additional savings are also achievable now cylinders behave like a hybrid,


tank now enables housing associations to have an auditable water hygiene strategy. Is it at a safe temperature? Has it been pasteurised recently? Is my tenant using hot water at all? The smart technology deployed on the Mixergy smart hot water tank has


allowed some really interesting data insights to be gathered. When given the opportunity to selectively heat a cylinder by volume (i.e.


1-100 per cent) the average state of charge of over 400 networked tanks was shown to be only 60 per cent, showing that over 400 customers are no longer needing to heat the full volume to serve their hot water needs. Volumetric control with a smart schedule has delivered up to £124 per annum in hot water bill savings for some users. This is made easy for tenants with a smartphone app, a desktop login and simple visual gauge or even a remote control, ensuring that even the most technophobic can still benefit from the technology. Data has also shown that there is less than 5 per cent probability of an


occupant using more than 60 per cent of a hot water tank in one event – and these rare events can be boosted and planned for rather than the ‘just in case’ daily full charge only offered by conventional cylinders. Measurement and control of the cylinders water temperature from top to


Estate constructed with Kingspan TEK


The Kingspan TEK Building System is providing a precise offsite building solution for one of the country’s largest Passivhaus developments in Bowthorpe, Norwich. RG Carter are constructing 112 of the 172 properties on the development to the Passivhaus Standard. After reviewing the market offering to achieve the demanding fabric requirements of the Passivhaus Standard, it was concluded that the Kingspan TEK Building System was the best solution for the project on the basis of technical specification and value offered. Kingspan TEK structural insulated panels (SIPs) feature a high-performance insulation core sandwiched between two layers of OSB/3.

enabling control of each available heat source. For example it can be set to use electricity between 3 am to 9 am, solar between 9 am to 4 pm and gas between 4pm to 3 am, meaning that occupants can reduce bills as much as possible by using whichever energy source is cheapest or most prevalent at any given time. Sensor networks on smart cylinders like Mixergy’s allow remote diagnostics


and maintenance to be carried out, reducing the number of field service visits required and improving the first time fix rate. Reheat recovery times are improved when charging the tank volumetrically –


reheating up to five times faster than conventional cylinders through use of its diffusers that prevent hot and cold water mixing. This means that housing associations can now install cylinders that are 30 per cent smaller than the one they replace, making more room for storage in their tenants homes. The opportunity to meet the demands of macro themes upon our


organisations while offering tenants a better user experience and lowering their costs is a challenge, but smart deployment of the right technologies can make this easier. One simple lifecycle replacement that doesn’t require an additional


infrastructure and can improve the asset management and maintenance strategy of the housing provider and effectively manage an estates fuel poverty and water hygiene is now in possible with the use of intelligent hot water cylinders.


David White is business development manager at Mixergy Insulation solution for Bristol development


A private development for contemporary urban living in Bristol is benefiting from the latest advancement in vacuum insulation technology and exceptional thermal performance with the Kingspan OPTIM-R E Roofing System. The Old Library is an exclusive new-build featuring 36 spacious studios and apartments in the vibrant, North Bristol neighbourhood of Cotham. Kingspan Insulation provided detailed information regarding the fitting of the Kingspan OPTIM- R E Roofing System, ensuring the ratio of Kingspan OPTIM-R E panels to OPTIM-R flex infill strips was optimised. This ensured that the U-value requirements were met without compromising on aesthetic design.
