CH4 Installations Ltd. A BASIC GUIDE TO GAS BOILERS This is our ‘Beginners Guide’ to the different types of gas boiler systems. Nowadays all new boilers are energy-efficient, so choosing the right boiler is really about what is most practical and efficient for your home and usage requirements. Since 2010, all boilers must be (condensing) A-rated for energy efficiency. THERE ARE 3 MAIN TYPES OF  BOILER SYSTEM: Combi Boilers Combination Boilers, often referred to as ‘combi boilers’, are the most popular type of boiler in the UK. Combination boilers are energy efficient because they heat water directly from the mains water supply as and when you turn on a tap or shower. This means that they can provide unlimited heating and hot water rather heating water and storing it, so there is no need for a hot water tank or cylinder in a cupboard or in your loft. Combi systems use mains water pressure, so they provide good water pressure without the need for a pump. They are most suited to a household where there are one or two bathrooms and where there is not a high demand for hot water to be used at the same time. System Boilers System boilers, also known as a ‘sealed system’, require a cylinder for storing hot water, which is usually placed in an airing cupboard or the loft. The main heating components are in the boiler so there is no need for a water tank in the loft. These boilers are often used in homes with loft conversions and are suitable for properties where you need to run hot water for multiple uses around the home at the same time. Although they do not provide instant hot water and they can run out of water, meaning you will have to wait for it to reheat. Conventional Boilers Conventional boilers, sometimes known as ‘heat only’ ‘regular boilers’ or ‘open vent’ systems are usually installed with a hot water cylinder in an airing cupboard fed by a cold water tank in the loft. These types of boilers provide stored hot water and are suitable for properties where you need to run hot water from multiple taps or showers at the same time. These systems are often used in properties with more than one bathroom and where a lot of water needs to be used at the same time. They are suitable for low water pressure or with old heating systems, where the higher water pressure provided by combi or system boilers may be too much. How to choose the right boiler for your home? We offer free professional advice There are also a huge variety of boiler manufacturers offering a range of models to choose from. In order to choose the right boiler for your home there are many factors to consider in terms of the type of boiler and performance requirements, before you can consider specific models that may be most suitable. It is of course important to consider both the existing central heating system, your usage requirements, as well as any improvements that you may wish to make to your hot water and heating system, such as smart heating controls as you will need to make sure the new boiler needs to be compatible with those too. As part of planning a replacement boiler or central heating installation our heating engineers will first assess the household before making any recommendations on boiler type and models to suit your requirements.

There is only one boiler and that is an Intergas boiler. Intergas boilers can be fitted to any system because any Intergas boiler can be either a heat only boiler, a system boiler, a combi boiler or even just a water heater. This is beneficial for anyone who has an old gravity system and need a new boiler but can not currently afford to convert the heating system at the same time. You now have the option to replace the old broken boiler now and convert the heating system in the future. For more info contact Pavlou Plumbers.

There are three main types of boiler all A rated efficient and condensing. A combi boiler will heat your radiators directly and switch to hot water on demand A system boiler will heat your radiators and your hot water storage cylinder set to the programme you desire, it also provides expansion and fill so does not require a feed tank in loft. A heat only boiler will make up part of the conventional system, loft tanks, copper cylinder, pump and motorised valves.

There are 3 types of domestic Gas boilers. All new boilers fitted are condensing boilers and new installations have to comply with ‘Boiler Plus’ regulations. Combination boiler: This type of boiler heats hot water instantaneously as the water passes through it. They are space saving as no other cylinders or tanks are required. The heating system is pressurised. System Boiler: These are usually fitted with an unvented cylinder or sometimes even a copper cylinder. A system boiler heats the hot water indirectly via a storage cylinder. It has some integral parts of the heating system built in ie the pump and expansion vessel and the heating system will be pressurised. Conventional/ Regular boiler: This type of boiler heats a copper cylinder indirectly. You will also have 2 tanks in the loft space to feed the hot water cylinder and heating system. The heating is low pressure fed via the header tank and the hot water pressure is also gravity fed. The controls are external unlike a system boiler.

Domestic gas boilers mainly come in 3 types. Heat Only: This is your conventional boiler, the only job of the boiler it's self is to heat the heating system water. These systems have an external pump, zone valves, thermostats and controls along with a separate hot water cylinder and cold water tanks. System Boiler: A system boiler still need a separate hot water tank but the boiler it's self will have its own built in pump, filling loop, expansion vessel and pressure relief valve. Combi Boiler: A combi boiler doesn't need any form of water storage tanks or external components. The boiler unit provides instant hot water on demand or heating. It has its own built in pump, diverter valve, filling loop, expansion vessel and pressure relief valve.
