Andrews Water Heaters’ sizing tool is better than ever

Andrews Water Heaters has launched a new and improved version of its original sizing tool for water heater specification: Size-it.

Quicker, personalised and now accessible online on any device, Size-it helps specifiers to select the most appropriate Andrews Water Heater for a project. Using the ‘quick calculator’ function, users can get advice on the most appropriate product range for one of 12 project types including schools, leisure centres, and launderettes.

For more detailed sizing recommendations, specifiers can create an account in just a few simple steps and enter further information such as the temperature of hot water needed, the number of fills required, and duration of use for each type of appliance on the site. The full version of the tool accurately recommends the most suitable Andrews Water Heaters product solution for the job, along with a detailed summary report and all the technical information required to complete a hot water schedule.

Available for free via the Andrews Water Heaters website and www.sizeit.co.uk, the new tool allows users to manage and share a portfolio of projects and tailor the sizing to their exact property type and hot water requirements. The new Size-it links to the most up-to-date information on CAD, BIM and ErP labels when recommending a product to allow for simpler specification, and all information given can be easily downloaded as a summary or detailed report.

The tool aims to combat the issue of oversized systems, which can be problematic. The capital outlay is greater on larger plant, more energy is used in operation, and, if the demand for hot water is not there, it will cost the end user more in energy bills. This is all before considering that a larger plant takes up more room, which can cause installation issues it there is only a limited amount of space allocating to siting equipment.

Size-it calculations are based on the hot-water requirements guidance in CIBSE’s Guide G Public health and plumbing engineering and Andrews Water Heaters’ 40 years’ experience in hot water generation.

Chris Meir, sales director at Andrews Water Heaters, said: “Size-it was the first sizing tool of its kind for the UK water heating industry, and remained the market leader. Following recent insight into the needs of our customers, we’ve made the UK’s number one sizing tool even better.

“Size-it is now more user-friendly and informative than ever before and can be accessed online on any device. Users can save project templates for future jobs, share sizing and can earn a 2% heat efficiency credit* just by using the tool.

“Ultimately, we’ve made it as easy as possible for busy professionals to get the information they need in order to match the right product to the right job.”

Introduced in 1996, Andrews Water Heaters’ CD sizing tool was the first of its kind for the water heating industry. The launch of the new Size-it is the latest milestone in the company’s successful history and coincides with its 40th anniversary celebrations.
