Condensing Gas Boilers
Condensing gas boilers are ideal for heating homes during cold seasons when we all long to keep warm amidst the creeping cold. Though these boilers come in different kinds, conducting condensing gas boiler reviews can go a long way in helping you find the best condensing boilers in the market. You need to understand that condensing gas boilers prices differ depending on the kind of boiler and other features.
Various kinds of Condensing Gas Boilers
There are three kinds of gas boilers, the regular, combination and system boilers.
Regular condensing gas boilers: These are also known as conventional or traditional boilers. These boilers come with a cistern for cold water that is stored in the loft. The boiler also has a copper cylinder where hot water is stored up. This is normally fitted inside the airing cupboard. Other features that come with the regular boilers are the expansion and feed cistern, the boiler along with extended controls.
Combi condensing gas boilers: These are the most popular condensing gas boilers in the market. Combi boilers heat the water as it is needed. They do this by directing water from the main source to the boiler. It heats the water without storing it and since this kind of boiler has no tank, it occupies less space in a home. It is therefore good for small homes that have limited space. The good thing about combi gas boilers is that it takes a short time to heat the water and the how fast water flows depends on how fast the boiler heats it. This makes it hard or even impossible for two people to simultaneously use hot water. It therefore good to ensure that you don’t do dishes when another person is in the shower if you are using s combi boiler.
System condensing gas boilers: These boilers kind of form a middle way between combi and regular boilers in terms of space demands and supply of hot water. System boilers do not have cold water storage tanks but they do have tanks for storing hot water. This means that you have hot water flowing in multiple facets and also, you need enough space to place the water tank.
How do condensing boilers work?
Condensing gas boilers allow heat to rise up via primary heat exchanger. Once at the top, the gases are redirected and diverted to a secondary heat exchanger. This reduces the gas temperature in the flue to around 55°C. This decrease in temperature causes the water formed during a combustion process to condense. In droplet form, the water falls due to gravity and collects at the base of a flue manifold. The other remaining gases are then expelled outside through a fan supported balanced flue. Condensation produced inside the appliance is drained into a waste pipework for discharge or outside into a soakaway.
The best gas condensing boiler for you
In selecting suitable condensing gas boilers, condensing gas boilers comparison is important to determine which one meets your needs. Since they use elevated storage systems, regular condensing gas boilers are great in keeping water pressure in check in case the pressure goes down. The availability of a hot water storage tank makes it possible for these boilers to supply hot water to several taps at the same time. If your house has a loft that is not in use, it is advisable to purchase a regular boiler particularly if there are many people living in your home who would need to use hot water simultaneously. Due to the space needs, regular condensing gas boilers are not suitable for small houses. For small apartments, the combi gas condensing boiler is more ideal and practical. If you have no option but to use a combi boiler and would like to avoid hot water lags, get the one that has the feature to keep hot. You may want to get the system condensing gas boiler if you have a big house but want to spare your space for other things.
What you need to do before buying your gas boiler
Before you buy your gas boiler, you need to conduct some research. Research to understand how different condensing gas boilers work. Take time to research on different manufacturers of boilers such as British gas condensing boilers so you know what they are offering as well. You may want to find out how modulating condensing gas boiler and natural gas condensing boilers work and how they are different in terms of cost and energy consumption levels of condensing gas boilers.
