Do you require a vented or a sealed heating system
Central heating systems have developed and that there are now many different forms each with differing advantages and disadvantages according to your needs. In this page we will discuss that the types of central heating system available to help you match them to your requirements. The primary component in a central heating system is the central heating boiler and this will be selected in accord with your needs.
Air conditioning systems are not yet a frequent feature in households whereas every northern European dwelling is built with a form of central heating. Most existing houses and virtually all new home developments now incorporate central heating systems to heat the household and furnish hot water.
The value of central heating systems is fully realised in winter although most are also used to supply hot water every day of the year. No one would deny how a dwelling is changed when we install an economic heating system. Another crucial role for the central heating system is to create hot water. Reliability is a major requirement for your central heating system. Systems tend to last for fifteen years and you will need one that is both economic and reliable.
Pumped systems and sealed central heating systems are the two primary forms.
pumped/vented systems are the most common. You will find that this configuration incorporates a feed and expansion tank in addition to a hot water cylinder. Hot water expands and in this type of system flows back to the expansion tank. The expansion tank needs to be installed higher than the other system constituents and most often this will be placed in your attic.
As thinking develops sealed systems are now more normally being installed in homes. An advantage of a sealed system is that it has no demand for an expansion tank. A sealed Central Heating System is connected to the mains water supply to allow the removal of the water feed tank. There are no tanks or piping in the loft, you will get the following benefits when adopting a sealed system:
- frozen winter pipe work from copper pipes in the attic it is now eradicated
- your upkeep requirements are reduced as there are fewer constituents
- less pipework and joints to leak
- sealed systems do not have air locks and the absence of air trims the likelihood of internal corrosion
It is usual for the water supply pressure to alter and that this is dealt with by incorporating a pressure vessel. A safety valve will open if the pressure is higher than advocated. Similarly cold water is allowed into the system if the pressure is lower than the recommended level.
