Why THERMOSTAHL ECW 15 does not reach set temperature?
- MMichelle HodgesAug 10, 2025
The THERMOSTAHL Boiler might not be reaching the set temperature due to several reasons. The fan could be blocked, or its regulator and thermostat might not be functioning correctly, so check or replace the fan. The air passages might be blocked, so clean them. The boiler itself might need cleaning. Ensure the boiler is started correctly. There might be insufficient water in the system, so fill it. The pump debit could be too high, so regulate the pump speed. The boiler might be under dimensioned. The fuel used could be of bad quality, so change the fuel. Finally, there might be insufficient chimney draught, so check or clean the chimney.
