Central Heating Systems: A Simple Guide

Central Heating Systems

Your house temperature is a crucial element in ensuring a comfortable living. Winters can get extremely uncomfortable if your house is not centrally heated and doesn’t have sufficient hot water to allow for convenience.

A central heating system is a central unit in the house that maintains heating for various components in the house. These heating systems, as opposed to area-dedicated heating systems, maintain the temperature of the entire house. There are various types of heating systems differing in terms of the boiler system that they use. There are three main types of heating systems from which to choose; a conventional heating system, a system boiler heating system, and a Combi boiler heating system.

Types of central heating systems

1.      Conventional heating system

A conventional heating system is perhaps the most common central heating system for home use. These operate on two water tanks with one situated at a higher level than the other. It relies on gravity as its primary tool. The water tank that holds the hot water is kept in the higher tank. It is usually placed in a cupboard or loft on a high floor of the building. The other tank is placed in an expansion tank with a hot water cylinder. The hot water from the higher tank flows down to the lower floors naturally by gravitational pull instead of using artificial pressure. The water in the top tank is heated by a boiler and as soon as the hot water ends, more water is heated. The conventional central heating system, however, is that it takes a lot of time to heat the water and it is less efficient in terms of heat conservation. Heat is lost from the pipe-work and energy is wasted even as water that is not used is kept heated.

2.      System boiler central heating system

A system boiler is available in two types; a vented low-pressure and an unvented high-pressure system. This boiler system has an extra storage tank that helps maintain the hot water. Yes, this system has an additional hot water cylinder but most of the remaining components are situated inside the unit itself. A system boiler is cheaper, much faster, and more efficient than the conventional system. However, it does take more cupboard space. This type of boiler is ideal for a larger complex and if used in a smaller home, it wastes energy as not much hot water may be needed.

The unvented water heater is a sealed system. This also includes a pressure relief valve and a pressure gauge. These additional components eliminate the need for a feed and expansion tank.

3.      Combi Boiler Heating Systems

In modern homes, a Combi Boiler is the heating system of choice for most. A Combi boiler heating system is an efficient and cost-effective alternative that also removes the need for an additional water tank. Combis use the main pressure water system and therefore do not need a water tank to be placed at a height. Another efficient additional feature is that they can instantly heat the water without needing any hot water cylinder. The fact that it is connected to the mains water supply means that you also do not need a water pump for a power shower.

Today, Combis are the popular choice because they are much more compact and can easily fit inside a cupboard all together. Its instant heating is another one of its perks. This means that you can rely on it in cases of emergencies without having to wait for the water to heat. These heaters are also available in a number of different types. These boilers are available in electric, gas, and oil variants while all others usually only have a single power option. This makes it possible to install a new Combi boiler without having to change the power system.

There are numerous choices of heating systems in the market from which you can choose. Among these various boiler types and options, a good choice is a vertical radiator that is a very compact device and equally efficient as a traditional radiator. When choosing a central heating system for your house, do consider the pros and cons of each type.
