There are several types of water boilers in the market and it is therefore very important for users to always give it a second thought before choosing a water heater for purchase. First of all, before you buy a heater, determine the type of users using its services. Is it for personal home usage or for residential apartment usage? Well, let’s first of all look at the available types of water heaters so as to give you an insight on the basics of water boilers.
First, we have the Combi condensing boilers and they provide instant water heating without using a storage tank. This type of boiler is very effective for small homes where we don’t require much hot water and they are admirable due to their small size that could see them fit into a kitchen cabinet thus using minimal space. Secondly, we have the sealed system water boilers and they provide heating through a storage cylinder. It is ideal for large homes using more than one bathroom. We also have the open vent boilers. Water heating is through a cylinder and a water tank usually situated in the loft. It is very effective for multi-user situations where more than one tap can be running at a time.
With that in mind, you need to add more considerations so as to ensure you purchase the most effective and reliable water boiler. We all know that a new boiler is expensive, but always consider going for a new boiler rather than acquiring a second hand boiler. Boilers are accounting for the highest percentage of energy being consumed nowadays and whenever you buy an old boiler, it might not have the set standards for effective energy regulations and in the long run it might end up being more costly than it seemed. New boilers are effective in saving energy bills since they help reduce energy use by over 40 percent.
You also need to take a good look at the efficiency of the heater you are to buy. You will need a good heater that will ensure it converts about 90% of its fuel into heat. This will ensure you save both on energy as well as on time taken to heat the water.
It might also be of importance to consider the type of fuel supported by the water boiler. Nowadays, boilers are run by various energy sources including electricity, natural gas, liquid e.g. propane or even solar energy. Before you go for a boiler, know the ones that are extremely costly to use and those that are pocket friendly. Electric boilers have proved to be very costly since they are the least energy savers. Solar heaters, though not very popular, come in better energy saving adjustments putting in mind that they are offered in either passive or active configurations. Although these types are very expensive to purchase, they might end up saving you more in the long run than any other water boilers. They have also proved to be very cheap to use.
Similarly, consider the capacity as well as throughput values of the water boiler. You can easily estimate the daily usage of during the busiest hour. Go for the boiler that will have a First Hour Rating that is close to the number you estimated. Heavy users will require a boiler with huge capacity thus being advised to go for boilers with a tank.
Finally, most people ignore the most important factor. The material used to build the storage tank. If you choose a stainless steel tank, you will be acquiring the most long-lasting boiler since it will never rust and it is not prone to corrosion as compared to tanks made from Iron or any other easy to rust metal.
