Which installation kit do I need?If you have conventional gravity fed, or indirect, system which has a cold water tank in the loft space and hot water cylinder, then the standard 15 mm kit would be suitable. If you are still on 15 mm pipework but have a combination boiler, or direct type system, then you are better to go with the 15mm full flow installation kit. This has the benefit of using uprated fittings and connection hoses and ensures that you get a minimum of 15 mm bore through everything and therefore get no restriction on flow. If you have 22mm pipework, then the best choice is the 22mm high flow install kit. This is found on the majority of houses less than 10 years old and is generally used on feeding mains fed unvented hot water systems. If you are unsure, then please call us on 0845 10 80 685 or email for clarification. START HERE 15mm (1/2") Rising Main If unsure go with direct Direct system i.e. Megaflow or Combination Boiler Indirect system i.e. Loft Tank = = |
