THE BRAND NEW SIZE IT FROM ANDREWS WATER HEATERS – NOW WITH LZC SOLUTIONS
The Size IT electronic sizing programme from Andrews Water Heaters has been updated to reflect a number of new developments both within the industry and in regards to the latest Andrews products and solutions. As a result this innovative software now includes new products, easier user options and, for the first time, LZC (Low/ Zero Carbon) technologies.
The LZC section includes the fundamental principles of how to size a solar thermal system, taking into account basic load and solar fractions, with a choice of either flat plate or evacuated tube options. Other factors included in the calculations are: where the project is in the country, the annual amount of solar irradiation predicted, the size of the roof and the energy production available from different panel angles. A total of three different options can even be trialled on screen.
The latest models added to Size IT are the SF60 condensing continuous flow direct fired water heater and the brand new NEOflo single burner condensing direct fired storage water heater. The SF60 is designed to deliver large volumes of high temperature hot water for a variety of commercial and industrial applications and is available in seven outputs from 142kW to 539kW. The NEOflo is available in 200, 300 and 400 litre stainless steel storage tank options and has no internal circulators, so it can operate at pressures as low as 0.2 bar, thereby offering an alternative solution where mains water pressures are low.
There have also been a great many changes in the presentation of Size IT to improve its usability. In response to customer request, Size IT is now Vista compatible and has a larger screen size as well as an updated ‘install programme’ that is easier and faster to use. The Andrews Water Heaters and Potterton Commercial websites have recently been updated as well and visitors will soon be able to download the Size IT programme directly onto their computers from these sites. The programme will read the version of Size IT already installed and, if there is a more up to date version available, it will display a list of changes, asking the user if they want to update now or be reminded later.
