Hot Water Cylinders from Vaillant

Some boiler systems such as system and regular boilers, require a hot water cylinder as part of their installation. These systems are often installed in larger homes with multiple bathrooms which have a high demand for a constant supply of hot water. For families, a hot water cylinder means that you can run multiple showers, do the washing up and flush the toilet simultaneously without a negative effect on the system.

What is a Hot Water Cylinder?

A hot water cylinder is a well-insulated tank which stores water after it’s been heated. Water is heated through your boiler system and is then stored, at temperature, ready for you to use whenever it’s needed. By storing hot water in this way, there’s no need to run the heating system constantly resulting in lower energy bills, without subjecting household members to cold showers.

Do I Need a Hot Water Cylinder?

If you have a system or open vent boiler, heat pump, or solar hot water solutions then you will need a hot water cylinder installed as part of your heating and hot water system.

If you own a home with two plus bathrooms and a high demand for a constant supply of hot water, then installing a heating system which utilises a storage cylinder will ensure your needs are always met. For properties where low pressure is an issue and a pump is needed to support the flow of water to the shower, a hot water cylinder will ensure that water is delivered at the right temperature.
