In order to obtain accurate water pressure measurements, We always recommend using a plumber/installer to obtain this information with a water pressure gauge before you finalise any orders.
Gravity fed system
Gravity fed systems are commonly found in older properties where you will find a cold water tank in the loft and a hot water cylinder to provide water at low pressure.
Low Pressure – (LP) 0.2BAR
- 0.2 BAR
Combi boiler system
Combination boiler systems heat water directly from the mains and provide hot water on demand.
• No storage tanks in property
A 28KW combi boiler will typically provide between 1Bar – 1.5Bar pressure
*Pressure is dependent upon the age and size of the combi boiler plus the mains water pressure.
- 1.0 / 1.5 BAR
Mains high pressure
Unvented pressurised cylinders such as a megaflow, store hot water at mains pressure and deliver it to multiple outlets without losing pressure.
• Unvented cylinder with an expansion cylinder
• No cold water storage tank in the loft
• Stored hot water
• Balanced Pressure
• Limited to Mains Pressure
High Pressure – (HP) 1.0 – 3.0 BAR
- 1.0 / 3.0 BAR
