Possible Causes and Solutions for Excessive Consumption
and Other Issues in Heat Substation Existing Applications

When there is no hot water supply, what parts, issues, and solutions should be checked in the heat substation?
Check the movement of the thermostatic valve. The issue may be a locked thermostatic valve inner core. The solution is to replace the core.
Inspect the dirt collector. It might be clogged. If necessary, clean the dirt collector or replace the filter.
Check the flow rates of the heat exchanger. Decreased capacity due to scaling and reduced heat transfer surface connected to the system can occur. The solution is to replace the heat exchanger.
When a high heat consumption bill is received, what parts, issues, and solutions should be checked in the substation?
Check the movement of the thermostatic valve. The problem might be a locked thermostatic valve inner core. The solution is to replace the core.
Inspect the sensing cable of the thermostatic valve. The issue may be due to the cable’s compass deviation. The solution is to replace the thermostatic valve.
Perform a check on the actuator valve inner core movement. The problem might be the actuator valve inner core being stuck in the open position. The solution is to replace the core.
Check the capillary tube of the balancing valve. The problem could be due to leakage or cutting of the capillary tube, preventing balancing and resulting in high boiler flow. The solution is to replace the capillary tube.
Inspect the balancing valve. The problem may be blockage or tampering with the valve adjustment. The solution is to relieve congestion by pressing on the upper part and checking the settings. If the issue persists, consider replacement.
When there are heating complaints, what parts, issues, and solutions should be checked in the substation?
Check the circulation pump. The issue may be a blockage in the connected pump. The solution is to release the blockage from the upper part of the pump and provide movement. Then, turn off and on the power. The pump will make the initial movement at full power, and the blockage will be cleared.
Monitor the boiler temperature. The problem may be the boiler operating at a low temperature. The solution is to increase the temperature by consulting with management.
Inspect the balancing valve. The problem could be blockage or tampering with the valve adjustment. The solution is to relieve congestion by pressing on the upper part and checking the settings. If the issue persists, consider replacement.
Check the pressure of the indirect heating line. The problem may be a drop below one bar, causing the pump not to work and air to accumulate in the system. The solution is to bleed the air and feed water up to 2.5 bars through the filling valve to maintain a closed-circuit heating system.
