Heating controls manufacturer Danfoss is counting the days to Christmas with the return of its prize-packed online Advent Calendar competition.

Installers can enter the competition free of charge when they register for the new Danfoss Elite loyalty programme on the website.

The competition gives Elite installers a chance to win some great prizes every day from 1 December to Christmas Eve 2013, from food hampers and shopping vouchers to the latest must-have electronic gadgets.

Behind each day on the 2013 Danfoss Advent Calendar is a multiple choice question relating to the company’s extensive range of energy saving solutions, from programmers and thermostats to TRVs and motorised control valves.

Whether it’s about how one of Danfoss’ innovative products works, its key features, or savings potential for householders, the answer can be found on the company’s website with the help of hotlink hints that take you to the relevant page.

Submit the correct answer from a choice of three and you’ll be entered into a free prize draw for that day. Danfoss will notify the lucky winners by e-mail and send them their prize.

Danfoss believes its interactive Advent Calendar is a fun way to increase awareness of how high efficiency heating controls can reduce domestic energy consumption, while also providing heating professionals with a means of growing sales by installing or upgrading customers’ heating controls.
