Gas Heating System Choices
Gas Heating System Choices
Nowadays there is a choice of boiler types to power your central heating system according to your dwelling requirements. This page focuses on the type of system available. The main component in a central heating system is the gas boiler and this will be chosen in accord with your needs.
In terms of the systems within your household the central heating system will be one of the most expensive and the one that is in everyday use, and cooling systems are seen less often. The majority of new houses that are being built in this day and age are built with a Central Heating System.
The value of central heating systems is fully realised in winter although most are also used to furnish hot water every day of the year. Heating your dwelling provides a restful and cosy atmosphere. The central heating system also can give you a cheap source of hot water. Dependability is a major requirement for your central heating system. You want to match the central heating system to your home requirements so that it both meets your requirements and uses energy efficiently.
Pumped systems and sealed central heating systems are the two primary forms.
The pumped/vented system is most often seen. This type of system has a feed and expansion tank in concert with a hot water cylinder. Hot water expands and in this type of system runs back to the expansion tank. The expansion tank needs to be installed higher than the other system parts and most often this will be placed in your attic.
Sealed central heating systems are now more commonly installed in new homes. A sealed system, as the name suggests is a closed system so no water tanks are needed. The water for a sealed Central Heating System is rendered direct from the main water supply. It feeds directly from the primary water supply. There are no tanks or pipework in the loft, seaing the system and removing the need to vent the hot water has some advantages:
- you don’t need to care about copper piping in the loft freezing
- fewer elements mean low get costs
- fewer leakages from pipe work seals
- the sealing of the system precludes air entering which could lead to inner corroding or the development of an air lock
A pressure vessel is included in the system to deal with any pressure variations in the water supply. A safety valve will open if the pressure is higher than recommended. Similarly cold water is allowed into the system if the pressure is lower than the advocated level.
