There are several types of gas boiler from which you can choose, so its important that you understand how they differ if youre to make the right choice for your individual needs. It is also advisable that you find out what type of fuel is available in your local area if you do not already have heating installed or you are thinking of changing. Types of Central Heating Systems. The Conventional Heating System Conventional Home Heating System. Requires two water tanks located high up one a Cold Water Storage Tank the other an Expansion Feed tank, also requires a Hot Water Cylinder. The storage cylinder holds a large quantity of hot water that is available immediately or as soon as the feed allows. However when this store has been used up it has to be reheated, this could take anything up to 1 hour. This type of system is considered the least efficient as there are heat losses from the pipe work to and from the boiler to the cylinder and the cylinder itself. System Boiler Heating Systems System Boiler Heating System. System boilers come in two types, a vented low pressure and an un vented high pressure system. Both require a Hot Water cylinder. Vented system boilers require a storage tank but most of the other components are held in the unit itself which means that installation is quicker and cheaper. Also, the hot primary water is pumped through the system to the radiators and hot water cylinder resulting in a faster response and more economical running costs. Un vented system boilers incorporate the equipment necessary to form a sealed system including a pressure relief valve and a pressure gauge, removing the need for a feed and expansion tank. Combi Boiler Heating Systems Combi Boiler Heating System. Combis are now the most used form of central heating boilers. Most Combis run on mains pressure water, thus do not require tanks to be placed in the loft. They also eliminate the need for a hot water cylinder as they instantly heat the water when it is needed. Another benefit with the combi is that, due to it running from the mains water supply, you can create an effective power shower without the need for a pump. Combi boilers require the least amount of plumbing thus offer a cost saving when installing. Condensing efficiency boilers versus standard efficiency boilers. Condensing efficiency boilers versus standard efficiency boilers. Whilst all new central heating boilers have to meet government set minimum standards of operating efficiency SEDBUK Band D or above, like cars and household appliances such as washing machines, some boilers operate more economically than others. Condensing boilers hence low emission levels and are very energy efficient. Old conventional boilers run between 6. Dell Dimension 9150 Sata 3 Cables. Types of fuel. Gas Gas Boilers and Condensing BoilersGas is the most used fuel for heating the home, it comes in two forms Natural Gas This is piped to your home via a supply company. If you require natural gas and it has not been connected to your home yet then it can cost a lot of money to get connected. You can install a gas central heating system yourself but will need a Corgi registered installer to make the connection to the gas supply. Natural gas is very convenient and there are a good variety of heating systems that can be powered by gas, such as Combis, back boilers, wall heaters etc. Another benefit is that you will not run out of fuel for your heating. LPG This is an alternative to natural gas where it is too expensive or impractical to get natural gas. LPG is supplied to your home via large orange cylinders that stand about 4 feet tall, you usually require two of these cylinders to be fitted with a valve to switch between the two as there are no gauges on them to tell you how full they are. LPG works in exactly the same way as natural gas but you will need a boiler that can be made compatible via a conversion kit. Oil Boilers. Oil fuels some of the most efficient boilers available, the choice of heating systems are fewer than with gas being restricted to just boilers. In most cases to run an oil boiler you will need a tank to be installed outside your house, these are usually large and very hard to disguise, you also have to conform to a variety of regulations in sighting it. Another thing with oil is that if you let it run out then you will need a heating engineer to re prime the system before you can get it working again. Solid Fuel Boilers. Solid fuel heating boilers are mostly limited to back boilers, or kitchen ranges. There are some solid fuel boilers which run the same way as other fuelled boilers and use automatically fed pellets from a hopper situated outside the house we do not supply these. Most solid fuel heating systems are inefficient as they consist of open fires they also can be messy and require cleaning out once a day at least. Solid fuel comes in a variety of forms, coal, wood, etc. Electric Boilers. Until recently effective Electric central heating was limited to storage heaters or blown air systems. These were both run off cheap rate electricity supplied in the small hours, and in some cases for a short top up period in the afternoon. Though storage heaters the most popular are reasonably efficient they have a problem of being on all the time, so if you have a hot day after a cold day in the winter, you will have heating even though you dont need it. They are also susceptible to drafts which can discharge them very quickly indeed. A new form of electric powered heating has appeared recently in the form of electric heating boilers. These can directly replace other boilers in conventional heating systems they are very compact, light and can be run off cheap rate electricity. Another benefit is that they are completely silent. Retrofit Central Heating Homebuilding Renovating. Homes in need of renovation often have dated, inefficient or downright dangerous central heating systems, while others will have none at all. In these cases, it will be necessary to plan to have a new boiler and radiators installed. A central heating system consists of a heat source combined with connected heat outlets this usually means a boiler and radiators, but it can also mean underfloor heating and renewable heating solutions. You will need to find a properly qualified heating engineer to install your new system and your choice should depend on the type of boiler you are having fitted. Gas boilers engineer registered with Gas Safe. Solid fuel burning boiler eg woodburner a HETAS member should be considered. Oil burning appliances and services an Oil Firing Technicians Association OFTEC member. Electric boilers need a qualified electrician or a boiler engineer with experience of electrical boilers. So, What Will You Need For Your New Central Heating SystemIn short, a boiler and, depending on the type of boiler you opt for, possibly a hot water cylinder and maybe a cold water tank plus radiators and controls for the system. You can calculate how many and what size radiators you will need yourself there are various rough calculators available online to help, or ask your heating engineer to do this for you. A rooms overall heating need is measured in British Thermal Units BTU and radiator manufacturers and suppliers will provide the BTU output for each model. How Much Will New Central Heating Cost The costs of the materials will vary depending on the system and specification you opt for. You will need to factor in the cost of your boiler, radiators and controls, including pipework, plus the cost of having them all installed. As a rough guide, to install central heating into an average three bed property with no heating system will cost between around 3,2. Find a tradesperson. Installing Central Heating Step by Step. Choose a boiler and select the radiators that will offer adequate heating for your home, along with new controls perhaps with the aid of a heating engineer. Your engineer should be able to help you come up with a plan for the system you want to install. You will also need to decide on a good spot for your new boiler and where you want to position your radiators. The radiators are usually installed first, at around four to six inches above floor level. The pipes are then laid from the radiators and valves to the boiler, after which the controls are then installed. The water and, in some cases, the gas is shut off while the boiler is installed. All of the radiator vents will be closed, the system filled with water and each radiator allowed to vent through. Finally, the boiler can be switched on and the flow of heated water balanced using the valves. Our estimate 35 days 34,2. Which System Combi Combination boiler systems heat the water as you need it so no need for a hot water storage tank. They also use mains water pressure so there is no need for an overflow tank. Gravity Fed Systems It can occasionally be better to upgrade these systems rather than replace. The negatives though include variable flow and the space the cylinders and expansion tank requires. High Pressure Systems These systems use mains water pressure, so they usually give lots of hot water at a good flow. They do, however, require a hot water tank which can add to installation costs.
