About System Boilers

System boilers are generally installed for homes with two or more baths. System boilers are pressurised with mains water and are accompanied with either a separate open vented or an unvented cylinder, usually situated in the airing cupboard.

Rather than trying to heat a lot of water instantly they can be set to heat a larger volume of water indirectly. Vented cylinders have a tank above the cylinder in the airing cupboard or loft and rely on gravity to supply the hot water. Whereas un-vented cylinders are mains cold water pressure fed. The size of the tank is usually designed around how many bath and shower rooms the property has.

• They take their water from the mains so no tank needed to fill the radiators up.
• Hot water delivered to many taps at the same time.
• Economical to run.
• Built in components to make the installation neater and faster.

They are most suitable if:

• You are happy with your current system and want a like for like replacement.
• You have more than one bathroom.
• Your mains water pressure is low.
• You have a standard boiler but you want to remove the cold water tank in your loft.
