New Conventional Boiler Installation - Regular, Heat-Only & Open Vent

Conventional boilers (also known as regular boilers, heat only boilers or open vent boilers) are designed to provide both heating and hot-water with the use of an additional cold-water tank and hot-water cylinder. These boilers could be particularly suitable for households where multiple people are likely to require hot-water at the same time.

Here at HomeServe, we supply a range of heat only boilers and it is our aim to help you select the right boiler for your home. Our online free quote tool could provide you with a personalised quote for the installation of your new conventional boiler.

What Is A Regular Boiler & How Does It Work?

Heat only boilers or Regular boilers are often regarded as the traditional form of central heating. These boilers use a cold-water tank and a hot-water cylinder for storage, which both tend to be installed into loft spacing. Once the fuel has been ignited, the heat exchanger warms water which is then transported to the hot-water storage tank by a pump. This stored hot-water is then sent to your taps and radiators when you need it.

How do regular boilers work? A Conventional boiler system is built with an expansion vessel, which is used to keep the pressure constant by controlling the heated water as it expands; this helps prevent pumps and pipes from bursting. A feed and expansion tank is additionally required in order to help maintain your heating system’s water levels; it could also be used to store extra hot-water.

Advantages of a Conventional Boiler

Heat only boilers supply a variety of homes with heating and hot water, providing you with a number of potential benefits. These include:

 

They’re designed to provide hot-water to multiple taps simultaneously

Conventional boilers could be a great choice for you if you have a high demand for hot water or if you have multiple bathrooms, as these boilers are designed to deliver hot-water to numerous taps simultaneously.

Often quick, easy and cost-effective to install

If your home already has a traditional central heating system, installing a new open vent boiler could be a quick and easy task. It could also be cheaper as a change in boiler type require additional parts and labour.

They could be fitted with an additional electrical immersion heater

These devices are designed to provide you with a back-up in case your boiler ever suffers a breakdown. With an immersion heater you could still have access to hot water even if your boiler is on the blink, as they run off of electricity as opposed to gas or oil. This could be one of the main advantages of installing a conventional boiler, as some other boiler types typically don’t have this feature.

Which conventional boiler do I need in my home?

Here at HomeServe, we aim to supply a range of conventional boilers so that we’re able to meet the needs of a variety of homes. It is our goal to provide you with the help and advice you need to help ensure that the boiler you have installed is able to heat your home effectively and efficiently.

Factors such as your home size and central heating demands will help determine the kW output that you’ll need from your new boiler. A boiler’s kW output influences its ability to cope with your central heating needs and tends to be based on the number of radiators and bathrooms that you have in your home.

For example, if you choose to install a boiler that has a higher kW output, you could receive a higher the supply of hot-water. However, this does not mean that you should purchase a boiler with the highest output available, you must ensure that your boiler’s size matches the size and requirements of your home.

The estimated guide below could help you get a better idea about the kW output that your home may require:

12-15kW 1-3 bedrooms, 1 bathroom
18-24 kW 3-4 bedrooms, 1-2 bathrooms
30kW + 4 or more bedrooms, 2+ bathrooms
