The advantages and disfavours of the diverse heating boiler models
Central Heating systems come in different forms. A central heating boiler, central heating radiator and pipework are common components in many of these Central Heating Systems, they are simple in plumbing terms.
In most parts of the UK air conditioning is hardly required because of the average temperatures of those regions. Most of us need a decent heating supply far more; this is why the majority of new houses that are being built in this day and age are built with a Central Heating System.
Heating is essential, particularly whens winter is heading our way. A heated home has a comfortable and enjoyable feel to it. So you want to be sure that your Gas Central Heating System is dependable. Additionally, your central heating system should also be safe, user-friendly and durable.
There are two main types of Central Heating Systems; pumped/vented and sealed systems.
Pumped/vented systems are the ones that many homes have and they have the most components resulting in potentially higher maintenance costs. A pumped/vented Central Heating System has a feed and expansion tank. Your radiators are heated and your water is stored in a hot water tank. The expansion tank has adequate space to accommodate any water expansion that occurs due to heat. It is normally placed at the highest place of the house like the loft area, taking up space. The hot water tank has two main functions; to heat the house and and provide hot water for washing.
Most houses, especially the old ones will have a vented/pumped heating system.
A Sealed Central Heating System is a relatively modern technology, and is being adopted by many homeowners today. No water tanks are needed with the sealed system. This unvented system eliminates water tanks and attic plumbing, thus giving a number of advantages.
- The problem of freezing pipes is eliminated.
- There won’t be any repair work on the tank or pipes which will be in the attic for a pumped/vented system.
- The risk of leaks is decreased.
- Reduced risk of air locks, corrosion and sludge as there isn’t a chance of air being drawn down into the system through open vents as the system is sealed.
- It is possible to flush out the system if required by using the mains water supply.
Such a Sealed Central Heating System is installed with all the required gauges, controls and safeguards. No tank feeds a sealed system, the supply comes directly from the mains. It is plumbed straight into the main water supply.
The system also has a pressure vessel which contains compressed gas, it controls the variations in pressure and a diaphragm is used to separate it from the sealed system. If the pressure is very high in the system, then the water will escape from the safety valve, and if the pressure is too low, then the safety valve will open to let the water in.
Compared to any other form of heating, Gas Central Heating systems are by far the most practical and economical. They also offer you all round control which is more than most heating systems do.
