As one of the most successful applications of the geothermal energy in buildings, the air-soil heat exchanger (ASHE), which is also called earth-to-air heat exchanger (EAHE), earth-air tunnel (EAT) or underground air tunnel (UAT) [15], has attracted extensive attention over the last few decades due to its simple structure and the low operation cost [16, 17].
If you have an iron heat exchanger, then you need to find an iron repair liquid, which uses chemical reactions to seal holes in iron. Pour a little bit of the chemical on the hole, and leave it to dry until it seals around the exchanger. Step 3 - Aftercare. Now that you have fixed the heat exchanger, replace it in the furnace.
