    I have a Baxi Duo Tech 28 HE. According to an online search with the serial number and GC number, I should have a 20-plate heat exchanger. So, I purchased a 20-plate unit. However, when I removed the old part, it appears to have 12-14 plates. Is there any harm in installing a 20-plate exchanger...
