A boiler is a must-have of every home, as it provides hot water every time we need it. However, if you plan to replace an old boiler or a faulty boiler, or simply get a boiler for a new home, the task can become a challenging one. With so many products available on the market, it is hard to decide. More than this, you want to make sure that the boiler you purchase is also adequate for your household needs. So, what kind of boiler should you choose? The following guidelines are meant to help you. Or click here to speak to us.

What to bear in mind when looking for a boiler?

The first thing you need to think about is the space where the boiler will be installed. If you have a special room in the house, like a laundry room, where you have a generous amount of space available, then size won’t be a problem. But if the boiler will go in a closet-type of space, then every inch counts. So, make sure to first take the measures of the available space. This way, you will know to look for boilers that will fit without a problem.

Measuring the available space will turn out to be even more helpful if you’re looking to invest in a larger boiler. Classic boilers, like the open vent or conventional models, are usually among the largest. If you noticed your old boiler had a hard time providing all the hot water your household needs, getting a larger version will definitely help. But, when the available space is limited, taking its measures into account will help you narrow down the list of options, without a doubt.

The types of boilers available on the market

Before you make any choice, it is worth knowing a little about each type of boiler available these days on the market. Even if you know something about boilers, maybe it doesn’t hurt to check this info as well, making sure the knowledge you have is the right one.

  1. The open vent boiler

This type of boiler is also known as the conventional type. When it comes to replacing an old-system boiler, this is usually the recommendation. However, this option will not fit all cases, so it is worth paying attention to its specifications. As the name suggests, this type of boiler has an “open vent” with a tank that stores cold water and another tank designed for expansion, which is installed in the attic in most cases.

Besides the boiler, you will also need a cylinder for hot water. This will allow you to enjoy hot water in the house whenever you need it, as the cylinder’s job is to make sure hot water will run through the taps or shower heads throughout the day. Why do you need a cylinder? Well, open vent boilers are known for being used for heating only, so the cylinder will help you solve the hot water problem. Due to its size and power, this type of boiler is great for homes with multiple bathrooms, as it can provide hot water fast throughout the entire house.

What recommends the open vent boiler? This type of boiler is ideal if you already have an open vent system installed in your home. If this is the case, you will save a good deal of money on the installation of the boiler. Also, it is a great choice if the pipework in the house is old, as it may not cope with the high pressure provided by the other types of boilers. And, believe it or not, it’s recommended to go for an open vent boiler if you’re dealing with low water pressure.

  1. The combi boiler

The combi boiler is a rather popular choice because it offers hot water when you need to use it. Quite compact, this type of boiler was created to hold all the necessary components in one single unit. So, if you have space-related issues, like not having an attic available for the installation of an expansion tank, a combi boiler can be a great choice. Also, it does not need a cylinder either. And if all these aren’t enough, the installation of a combi boiler is much simpler, which also translates into more affordable.

Its functioning principles are also very simple. In order to get hot water, all you need to do is to connect the combi boiler to your main water supply. Thus, when you will turn on a tap in the house, the boiler will start heating the water and deliver it to you in a matter of seconds. So, it is possible to say that this boiler is energy-efficient, as it heats the water instantly, not wasting any energy, transferring it to the water on the spot.

When is the combi boiler a great choice? It is ideal for small spaces, as it doesn’t need an expansion tank or cylinder for hot water. You can even hide it in the kitchen, as its size helps it fit inside a regular cabinet. The installation costs are lower because the unit works on simple principles. Also, since it is connected directly to the mains, the water is safer to consume. And, probably the most important advantage, it saves a lot of energy and time, when heating the water. Brands such as BAXI, Valliant, Worcester Bosch to mention a few very good manufacturers.

  1. System boilers

Are you split between choosing an open vent boiler and a combi boiler? Then the system boiler is the middle ground in this case. A system boiler will also be connected to the mains, just like the combi boiler, but will also feature a cylinder, needed for storing all the hot water. This way, you will have hot water available whenever you need to use any.

Because this type doesn’t need a cold-water tank, its installation can be done quickly and will also be cheaper than in the case of an open vent boiler. This option is ideal if you want to save space, as the system boiler is smaller than the open vent one, but make sure at the same time that hot water will be available in the multiple bathrooms of your house and the kitchen.

What makes a system boiler an adequate choice? First of all, even though it’s larger than the combi boiler, it still manages to save space. In other words, you don’t need an attic for its installation. It is highly responsive due to an internal pump that was built to serve the boiler’s needs only, so hot water will become available very fast. It is great for large families and households that have more than one bathroom, as it is capable of providing hot water to several taps at once.

Final aspects to consider before buying a boiler

Now that you know the particularities of each type of boiler and what could make it suitable in your case, it’s easier to make a final decision. So, first of all, think about space availability and how many taps you need to serve. A combi boiler, for instance, is more than sufficient for one or two bathrooms, while the other two versions are great for smaller homes, where there is a large number of taps. When you have a numerous family, the chances for the existent taps to be used at once is quite large. Thus, you will need a boiler that can meet the demand, making sure everybody enjoys hot water at all times.

You should also bear in mind the kind of installation you already have in your home. If you already use an open vent installation, then it is easier to get a similar one. Because the system is already in place, it is easier and quicker for the new boiler to be made functional. Choosing a boiler that is similar to the one you currently use, in terms of installation, makes things easier and cheaper for you. If you want to completely change the type of installation used for the boiler in your home, then you need to be prepared to face some serious additional costs. Also, you may end up having to deal with some repairs as well, if the pipework needs to be changed as well.

To make the boiler replacement process a straightforward one, it is recommended to stick to the same installation, if it shows no problems. Also, because every home is different, you need to take all its characteristics in mind when shopping for a boiler. How many people are living inside the house? How many bathrooms do you have? How’s the hot water demand in your home? Is the pipework old or new? What about water pressure? Is it low or high? The answers to these questions, plus all the information we provided earlier, should help you make an informed choice and enjoy the boiler that fits your needs best.
