What to do if the old-fashioned heater is not hot

With the arrival of winter, many families begin to use heaters for heating. However, older heating systems often run out of heat due to their age or improper maintenance. This article will analyze the common reasons why your old heater is not hot, and provide detailed solutions to help you restore warmth quickly.

1. Common reasons why old-fashioned heaters are not hot

2. Methods to solve the problem of old-fashioned heating that is not hot

1. Check and clear pipe blockages

Older heating systems are prone to pipe blockage due to scale or impurity buildup. Solutions include:

• Turn off the heating system and drain the standing water.
• Use a professional cleaner or a high-pressure water gun to flush the pipes.
• Perform regular maintenance to avoid long-term accumulation.

2. Eliminate gas accumulation

The air in the radiator will affect the circulation of hot water, causing the upper part to not be hot. Solution:

• Find the exhaust valve on the radiator and gently unscrew it with a screwdriver.
• Wait for the air to escape until water comes out and then close the valve.
• Repeat the operation to ensure that all radiators are exhausted.

3. Adjust water pressure

Insufficient water pressure can cause your heating system to not circulate properly. Solution:

• Check the boiler pressure gauge, the normal value should be between 1-2 bar.
• If the pressure is too low, open the water supply valve to increase the pressure.
• If the pressure is too high, reduce the pressure appropriately through the drain valve.

4. Inspect valves

Valve failure will directly affect the heat delivery of the heater. Solution:

• Check that the valve is fully open and make sure it is not stuck.
• If the valve is damaged, replace it with a new one in time.
• Lubricate valves regularly to prevent rust.

5. Check the boiler operating status

The boiler is the core of the heating system. If there is a problem, it will affect the overall heating. Solution:

• Check whether the boiler ignites normally and whether the gas or electricity supply is stable.
• Clean the carbon deposits or dust inside the boiler.
• If you cannot solve it by yourself, contact professional maintenance personnel for repair.
