## Questions & Answers

**Q: Is this item suitable for use with heater wrc-nsf**
A: wrc-nsf is not the model name/ number. wrc-nsf is water approval & certification

**Q: What is the length of this thermostat please?**
A: This version of the thermostat is 27cm or 10.5 inch in old money. There is a longer version 65110976 available from a number of different suppliers (not via Amazon) which is 44.5cm or 17.5 inch. I got mine from Advanced Water Company. The shorter one via Amazon is about £14 whilst the longer one I paid £21 for but various firms charge a wide variety of prices of anything up to almost twice as much; shop around! All measurements are for the brass element itself not including the grey connecting end.
