  We started producing electric in-floor heating in Jiangsu,China almost eight years ago in 2011 and have been growing steadily ever since. In 2015 we started selling our own specially-designed lines of in-floor heating products and two years later once we were confident had a winning product line we started offering them on-line to customers like you all across North Europe. During the summer of last year our sales had grown so much that we moved distribution and fulfillment from Lishui Distrct,Jiangsu to Jiangning Distrct, Jiangsu where we now have more space and offer quicker freight to many parts of the country more easily and at a lower cost than before.

  I invite you to check out our competitive pricing and to send us a request or call me personally if there is anything we can do to help you get started.
