How do conventional boilers work?

A conventional boiler is a water heating system that involves not only the boiler itself, but also a hot water storage tank, a cold water tank, and a hot water cylinder.

All of these parts work together to form the regular boiler system, which ensures that you always have enough hot water and that your heating runs perfectly.

Usually, homeowners put at least one tank in the loft, if not both, to allow gravity to help the water to travel down from the tank to the boiler.

The boiler itself is often kept in an airing cupboard or utility room lower in the property, where it is out of the way.

The cold water tank supplies the water for taps, and the water is heated using the hot water cylinder and stored there.

If the cylinder runs out of hot water, then more can be heated, but this might take time. This is where a combi boiler comes out on top.

The second tank is the hot water storage tank, also known as the feed and expansion tank. This tank contains cold water which is bought down to the boiler to feed the property’s heating system.

Throughout the day your central heating system works to keep your radiators warm, and the hot water tank in the loft of your home can help this system to run smoothly.

The system will send the cold water from the tank to the hot water storage cylinder, where it is heated and stored until your heating needs to be turned on to warm your home.

As such, both halves of your home’s hot water use are separate in a conventional boiler system, but they work together to ensure that your home is always warm, snug and supplied with hot water.

What are the alternatives to a conventional boiler?

If you don’t think that a regular boiler is right for your home, then there are plenty of other boiler options to choose from, so you can find the perfect solution.

Aside from conventional boilers, the most popular type of boilers on the market are system or combi boilers. A system boiler is similar to a regular boiler in that it has a hot water storage cylinder.

Unlike conventional boilers, system boilers do not need an additional water storage tank, as they heat the water and store it in the cylinder.

Combi boilers are even more compact and efficient, as they don’t need a water tank at all. Combi boilers heat water on demand, so they save space in your home.

These compact solutions can fit the entire boiler system into a small airing cupboard, loft space or kitchen cupboard, so they’re great for small properties.

Is a combi boiler right for my home?

A combi boiler is ideal for small homes or flats with few boilers and a small central heating system. A system boiler might work well for larger homes with multiple bathrooms that don’t need a regular boiler but could benefit from larger hot water and heating capacity.

In some cases, getting a new combi boiler quote or system boiler could be better than a conventional boiler for your home. For example, if your property has high water pressure, then a combi boiler would possibly be better than a conventional boiler.

Each of these types of boiler can work well for a modern home, so it can be tough to choose the perfect solution. If you’re unsure of which boiler you should install to heat your home and provide you with hot water, then talk to a boiler expert. We really like the combi boiler, they just work so well.
