How many hot water cylinder types is there?

Have you ever wondered about how many types of hot water cylinders there actually is?

We have complied a list of hot water cylinders for you, showing application, benefit and disadvantages helping you make an educated decision before purchasing your next hot water cylinder.

First of all we need to separate the PRESSURE TYPES from the MATERIAL TYPES. In New Zealand one can purchase almost any material type at three different pressures.

Most common pressure types available in New Zealand (Domestic Applications) 

    • Low Pressure, open vented systems where the pressure is provided by a cold water storage tank, open vent or rely on a pressure-reducing valve to reduce the pressure below mains pressure supply.
      Typical Pressure: 30 – 75 KPA, typically 3 – 7.5 metrets Head
    • Medium Pressure, open vented systems where the pressure is provided by a cold water storage tank, open vent or rely on a pressure-reducing valve to reduce the pressure below mains pressure supply.
      Typical Pressure: 75 – 120 KPA typically 7.5 – 12 meters Head
  • Mains Pressure, with a working pressure equal to incoming supply. Pressure can be limited to any requirement but using the appropriate valve work.
    Typical Pressure: Ranging from 120 – 1400 KPA (Domestic Supply is typically 350 – 750 KPA depending on requirement)

Mains pressure water heaters are the predominant type of new installation in Australia and New Zealand.

Shame on you BT plumbing and gas

We come across a lot of copy cats online. They steal content, ideas and images from others and later call it “mine”. Most content thieves don’t realise that search engines take content theft seriously and penalise such sites accordingly in organic search. A timeless record of all online platforms recorded by the Wayback machine will quickly reveal where content originated from. Search engines such as Google also provide time stamps, quickly disadvantaging such websites with copied content and this includes images.

In this instance several things were copied by BT Plumbing and Gas with the most obvious being images from our website. A quick Lead Gen site put together by the effort of others wanting to provide a unique experience to their users. Hot water cylinders Ltd legitimately purchased these images honouring the original copyright.

BT Plumbing and Gas may have employed a shoddy company or possibly knowingly copied our content. Either way, excuses aside, you are responsible for what you publish. We work hard to provide our users with an exceptional experience, contributing to a general better online experience fighting spam and content theft.

My advice is.. Try creating real authentic content that will actually benefit your users and if you completely fail in the “creativity” department and must “steal” other people’s work / ideas, do it in a way that is not so obvious to others.
