So how do conventional boilers work?

Conventional boilers are the most traditional form of heating in the UK. Although they are still in use today, their popularity has fallen recently in favour of combi boilers. Despite this, a conventional boiler could still serve your heating needs effectively.

A conventional boiler is also sometimes called a regular boiler or heat only boiler. This type of boiler uses hot and cold water storage tanks, usually installed in your home’s loft. The boiler unit is plugged into your mains, which supplies the water to be used in your home.

The boiler fires up by igniting its fuel, usually gas or oil. The heat exchanger warms up the water. A pump transports the water to the hot water storage tank for use throughout the day. When you set your thermostat, the hot water moves to through your radiators, emitting its heat energy to warm up the room. The hot water is also directed to water outlets in your bathroom and kitchen when you turn on a tap.

Another crucial component of a heating system employing a heat only boiler is the expansion vessel. This vessel controls the expansion of water as it is heated. This prevents your pumps and pipes from bursting, keeping pressure relatively constant throughout the system.

There is also a feed and expansion tank, located in your loft, which is filled with water. It keeps your heating system’s water levels relatively constant. It also provides an extra space for hot water to go, if the system heats up too much water.

Is a conventional boiler a good choice?

To determine whether you should choose a regular boiler to keep your house warm, it’s useful to understand the pros and cons of this type.

The advantages

A conventional boiler is extremely effective in providing the hot water your home needs. Depending on the size you choose, this boiler type is capable of heating up large amounts of water to cover your space heating and hot water demand.

With conventional types, you are able to get hot water from multiple taps at the same time. You don’t have to worry about water flow dwindling as more taps are used. This is in comparison to combi boilers, where multiple water outlet use means a diminished water flow. As such, conventional boilers are more suitable for homes with relatively low water pressure or 2 or more bathrooms.

For older homes that are more likely to already have a traditional heating system, it is much easier to just replace with a conventional boiler. An installation of a heat only boiler is much easier in older properties rather than switching to a new kind of system.

The disadvantages

With the hot and cold water tanks, a conventional boiler takes up a lot of room, particularly in your loft. This type is not suitable for homes with limited space. With these components, installation of a new conventional boiler system takes time, money, and effort.

The hot water cylinder needs proper insulation in order to keep the water hot enough for use in heating. This could increase your costs further during installation.

Also, a conventional boiler does not heat water on demand. It takes time for the unit to heat up water. This could be problematic if you run out of water during the day. The storage tank only holds a finite amount of hot water, so if your hot water demand exceeds what is stored in the tank, you’ll have to wait before you can enjoy warm air and water again.
