How do I know if my product is suitable for my water system?

Our products will be advertised with a minimum rating for the recommend pressure in your property, please see the below for reference:

• LP Minimum 0.2 Bar
• MP Minimum 0.5 Bar
• HP1 Minimum 1 Bar
• HP2 Minimum 2 Bar
• HP3 Minimum 3 Bar

It is always recommended to consult your installer before purchasing but in general:

LP systems are water tanks in your loft space with a hot water cylinder. These are older systems and are often used in older houses.

Combination boilers typically run between 1 and 1.5 bar water pressure.

Pressurised systems, sometimes called Megaflows, are usually 3 bar water pressure

Products with a lower pressure rating can always be used on higher pressure systems up to 5 bar. An LP product can be used on a Megaflow, but a HP3 cannot be used with a water tank without a pump.
