I have requested a number of sample carpet tiles, different ranges and colours. They were delivered very quickly and were useful to try a get the right colour and type of carpet for my living room and hall and possibly the two bedrooms as well. I was also impressed with the quality. I was disappointed, however, to find out that they are only suitable for underfloor heating up to 27c. I run my underfloor heating at over 40c and that is a normal temperature for underfloor heating. In fact up to 50c is not unusual. I'm not sure that any carpets would be suitable if 27c really is the maximum temperature.
