The benefits and disadvantages of the various central heating boiler models
Various types of Gas Central Heating Systems are available in the market. These systems for the most part are made up of a number of radiators, pipework and of course a gas boiler.
Whilst we need heating systems air conditioners are not needed in the United Kingdom and Europe because of the average temperature throughout the year. Many of us find proper heating a necessity; as a result most of the new houses being constructed today are built with a Gas Central Heating System.
With wintertime coming up round the corner heating should be at the front of your mind. A well heated house can help create a comfortable space for you to enjoy with your family. Your Central Heating System must be fault free as much as possible and efficient to cut bills. You Gas Central Heating System must give you the feeling of assurance that it is safe, simple to use with a long life.
Pumped/vented and sealed are the two main types of Gas Central Heating Systems on the market.
You will find pumped/vented systems in most homes at the moment. An expansion tank is present in a pumped heating system. The hot water tank performs two functions; firstly, supply hot water to your house, and secondly, provides heat to the radiators. The expansion tank has adequate space to accommodate any water expansion that occurs due to heat. A pumped/vented heating system requires that the tank be installed at the highest level within the house – such as an attic or loft space, certainly on the top floor. It not only heats the house, but also supplies hot water.
Older homes generally have pumped/vented Gas Central Heating systems.
A Sealed Gas Central Heating System is a relatively modern technology, and is being adopted by many homeowners today. This system doesn’t have water tanks as it’s a closed heating system, this will save you space and reduce maintenance costs as there are fewer components. There are benefits to have this closed type of system with pipework and tanks being unnecessary.
- The problem of freezing pipes is eliminated.
- No maintenance or repair work is required for the pipes and tank which would have been in the loft.
- This decreases the chances of a possible leakage.
- The air cannot enter the system as its sealed and hence there are lesser risks of sludge, corrosion and airlocks developing.
- The main water pressure can easily be used to flush out a Sealed system for easy maintenance.
The sealed Gas Central Heating system is a fully packaged system with all the controls and safety devices already in place. No tank feeds a sealed system, the supply comes directly from the mains. The main water supply feeds the system immediately under pressure.
Separated from the sealed system by a diaphragm is a pressure vessel, which contains compressed gas; this vessel is responsible for managing variations of pressure in the heating 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.
As compared to other heating systems, Central Heating systems are cheaper to run. They also offer you all round control which is more than most heating systems do.
