Despite the need for an airing cupboard, sealed system boilers actually take up less space than a traditional open vent boiler, which needs a second tank in the loft.
Installation of a sealed system boiler is quick and easy because all the parts are built within the boiler itself. This includes the components for heating and hot water.
Water pressure is very good with sealed boilers and you’ll also be able to have more than one hot water supply running at the same time. This is different to a combi boiler which will struggle to supply hot water to more than one outlet at the same time.
Is the sealed system boiler right for me?
The sealed system boiler works well with a larger family or home. It can supply multiple bathrooms with hot water at the same time.
You’ll still save space with a system boiler compared with an open-vented boiler as you only need room for one tank. However, you’ll have to wait for water to heat up so you won’t always have hot water on demand. You could end up using up the hot water supply quickly.
Many people with older and larger installations choose sealed systems when they replace their boilers. Although it proves more expensive, you’ll free up space in your home.
