Which Type of Condensing Boiler is the Right One for You?
If you’re meaning to switch to a new system, a condensing boiler is what you should be looking for. Ever since a 2005 regulation, in fact, all new systems installed must be condensing boilers. What does that mean, and how do you choose the right one for your home?
What is a condensing boiler?
Condensing boilers are highly efficient systems that manage to recover waste heat through a large heat exchanger (or sometimes a secondary exchanger) and by expelling cool gases from the flue. These boilers are called “condensing” because, from time to time, flue gases can get so cool that the gas vapours condense. The vapour itself is then used to recover even more energy: condensing boilers make use of exhaust gases that are usually released through the flue and go to waste, and the vapour is turned into liquid condensate in order to use this latent heat. Thanks to this process, condensing boilers are able to extract more heat from the fuel it uses compared to a standard efficiency boiler. Moreover, the system loses less heat through the flue gases.
How many types of condensing boilers are available?
You can choose between two main types of condensing boilers:
Regular Boiler: these systems are quite similar to old, traditional boilers, because they include a water tank and similar pipes, thus requiring smaller adjustments. You should choose this system if your house has enough space for the water tank and if you often need to have more taps open at the same time. Regular boilers ensure that water pressure will not decrease in these cases, and the family will not be left with no hot water.
Combi Boiler: condensing combi boilers are a great option if you have limited space in your apartment. They are the most compact option and heat water on demand directly from the mains, with no need for a water tank, so they can fit easily in a kitchen cupboard. They are the best solution for apartments or flats with no more than two bathrooms: if too many taps are open at the same time, you will experience decreases in water pressure.
Is there an alternative to condensing boilers?
Condensing boilers are considered more environmentally friendly because they are highly efficient and waste less energy than old systems. However, if you wish to become more sustainable, you can look into biomass boilers instead. These systems are fueled by wood, which is considered a carbon neutral fuel because burning logs and pellets release as much carbon dioxide as the growing trees absorb. By choosing a local certified fuel reseller (who ensures that new trees are planted) or even by using your own waste wood, you can get a completely sustainable boiler system. However, you will need space to store your pellets or logs.
