How to troubleshoot too little or no DHW in Danfoss Termix VMTD-F-B Water Heater?
- VvlarsonAug 15, 2025
If your Danfoss Water Heater isn't producing enough or any domestic hot water (DHW), several factors could be the cause: * A clogged strainer in the supply or return line may be restricting flow. Cleaning the strainer(s) can resolve this. * The DHW circulation pump may be faulty or set too low. Inspect the circulation pump. * A defective or clogged non-return valve could be the issue. In this case, replace or clean the valve. * Check if there is electricity.
