hi.
is there anyway conclusively to tell that a scaled HE is the cause behind DHW poor temprature?? some one has mentioned getting a digital thermometer and doing a thermal survey on the exchanger? but surley a scaled/ defective thermistor would also be the cause of poor dhw temp.any ideas as ive no wish to replace plate exchangers that are actually fine only to find its scaled thermistors?? help
