How to Fix Central Heating Problems

By Edited Dec 22, 2015 0 0

The primary need of a central heating system is to provide warmth to a portion or the entire building's interior. The distinguishing element between central and local heating is that in the former, the generation of heat happens at one place which could be a furnace room in a home or a mechanical room in a commercial building. There are several systems of central heating available in the market today but the potential central heating problems are more or less similar and hence troubleshooting them is also not very different.

Some of the common central heating problems include the below mentioned list. Radiator's top section being cold: This usually occurs when air has entered has entered the system and is trapped. This reaches the top and blocks the hot water from reaching that spot. To release this, heating must be stopped first. Using a radiator key, the air bleed valve which is on top of the radiator must be loosened. Water flows as the air comes out. The vent then needs to be closed and wiped dry. When radiators are cooler in one specific area, it is an indication that they are not well balanced. This is because the radiators near the boilers take more hot water than required. Use the lockshield valve to regulate the water flow to the radiator.

Sound of water gurgling in the heating system is an indication that air has entered and bleeding the radiator resolves the issue but care must be taken not to bleed them frequently. The help of an expert must be sought for. When a lot of sludge and rust builds up in the radiator, the bottom section becomes cold. The radiator must be removed and the sludge flushed out with the help of a hosepipe. In case of absence of heating or hot water, ensure that the fuse is not blown and the power supply is on. When the ball valve does not shut down the water supply, the cistern continues to fill and water spills out of the overflow pipe. The reason for this could either be a worn washer or an ill adjusted valve.

When water leaks from a connection or joint, it must be tightened with a wrench or spanner. If the area where there is a leak does not have a joint, then the pipe must be replaced. When there is insufficient water flowing through the boiler, it becomes noisy. The rate of water flow must be closely monitored especially with wall-hung boilers. When the heat pump does not blow or blows cold air, firstly the thermostat must be checked. The thermostat must signal the unit to generate heat and for this they must be set to warm enough. A tripped breaker or a blown fuse in the panel box could be reasons for this. The gas supply in the gas heat pump must also be checked for its continuity. When central heating problems arise, it could result in a lot of unnecessary trouble. Hence proper maintenance is advised and if you are unable to fix them yourself, it is best to find a local plumber to do if for you.

In recent times, the concept of underfloor heating has fast become popular because of the advantages it holds vis-à-vis a conventional heating system.
