Regular Boilers - The Ultimate Guide

Regular boilers are the oldest type of boiler but they are now manufactured keeping in mind the new energy laws. Conventional boilers are not obsolete, in fact, a lot of homeowners staying in larger properties opt for this. In the past years and even this year, we have been selling regular boilers. In this article, we would be discussing conventional boilers in great detail.

Now, in this article, we shall discuss combi boilers, an ideal choice for residential buildings. Are you worried about rising heating costs? Opting for a combination boiler is the best option. It’s pretty challenging to have an understanding of the world of boilers, there are so many models, so many manufacturers, a lot of sales and installation.

What is a conventional boiler?

Conventional boilers are also vented, regular or heat only boilers, these units operate your central heating via a separate boiler and water cylinder. Regular boilers are very simple and once upon a time, these systems were found in the majority of UK homes. But again with advancement, these days? traditional boilers are generally found in old properties. The units are ideal for homes having a huge demand for hot water or homes that have many bathrooms. Conventional boilers are not suitable for smaller properties because they require a cold water tank and hot water cylinder. There are wide ranges of traditional boilers so that you can choose the right one for your home.

Regular boilers would always need a hot water tank and also cold water storage mainly occupying the loft. But it depends on the system you are using, whether it?s vented or unvented. The unvented systems are also known as sealed systems; these operate mainly under pressure using the air bubble formed in the expansion vessel or cylinder. This allows expansion of the hot water; this is the reason why you do not need a cold water tank. When it comes to a vented hot water system, there is a vent pipe that connects the hot and the cold water tank and it works for expansion. Thus, it needs a cold water tank.

If you are residing in an area having a low water pressure, a regular boiler is the best choice. The best part is, unlike combi boilers these units can supply a large volume of hot water. One very important thing you must know that it?s a rule that all boilers will have to be condensing ones. This means if you install a conventional boiler today, it has to be a condensing boiler. Condensing regular boilers take up heat from the gases and fumes that come up while heating, the fumes are recycled, and this saves money, energy and carbon footprint. It’s the best choice for homeowners who are conscious of the environment.

The main differences are:

Boiler type Cold Water Storage Tank Hot Water Storage Cylinder
Regular boiler
System boiler
Combi boiler

How does a conventional work?

The cold water supplied from the tank is heated and transferred to the hot water cylinder. Once the system is fuelled, the heat exchanger immediately starts working, warming the water and this water is transported to the tank that stores hot water via a pump. This hot water is supplied into the taps, showers, and faucets. Traditional boilers might be open-vented or sealed and these boilers are best suited for homes that have older radiators. It might happen that radiators that become old might not be able to tolerate the elevated water pressure of other boiler types.

In case you have an already existing conventional boiler, its best to install a traditional boiler again. You need to pay for little pipe-work, the installation is easy and quick. There are conventional boilers that are also compatible with systems that run on solar heating; this lowers the wastage of energy and carbon emission. You must bear in mind that a regular boiler cannot produce instant hot water. You need to program the thermostat accordingly so that water is heated in advance.

Traditional boilers have an expansion vessel within; it helps to maintain a constant pressure by controlling heated water after expansion. This is vital as it safeguards pipes and pumps from bursting. An expansion and feed tank basically helps to maintain the water level of the heating system and sometimes used to hold surplus hot water.

Advantages of a conventional boiler

We still suggest conventional boilers to some of our customers because they do have advantages. Here are the set of pros:

  • Multiple taps can deliver hot water at a time ? This is a very big advantage that only regular boilers have. There would be more necessity for hot water in big families and in homes that have many bathrooms. Regular boilers are the best when the hot water demand is high. This is the reason why regular boilers are still the hot favourite for many customers.
  • Installation is quick and easy ? Do you already have a regular central heating system installed at home? If you are planning to replace, bear in mind that it?s cheap, easy and quick to replace it with a conventional boiler again. You would have to invest more if you plan to change the boiler type.
  • Energy efficiency ? The boilers that we sell at Plumbers 911 are all energy-efficient, A-rated and most environment-friendly. We sell boilers from the topmost brands like Worcester Bosch, Vaillant and also Ideal. If you get your boilers from our store, we ensure low energy bills. We are also selling all condensing boilers, thus very energy efficient.
  • Small leaks are not a problem ? The main advantage of a regular boiler is that small leaks are not a major issue and does not cause any loss of pressure in the shower.
  • These could be fitted along with an electric immersion heater ? All these devices come with a back-up because what if your boiler fails to work in heavy winters? If you have an immersion heater, you would have a backup and access hot water when required. This is one of the biggest advantages of installing a regular boiler because the other types are not equipped with the feature.

Disadvantages of a conventional boiler

Installing a conventional boiler also has certain drawbacks so take a look at those:

  • Boiler operation can be pretty expensive
  • Compared to other types of boilers, it?s a costly affair to install these units

  • You get hot water access as much as the tank can accommodate
