It is not a hot air one, but thanks for trying to help.Just tried our local plumbers and they only have square thermostats and I am after an oblong one, so I will try somewhere else on Monday.
We are in a rented property and the cover on the thermostat has cracked, we are after a replacement can anyone help with where to get one non of our local plumbers can help? or if not where what would be an easy replacement?
