If your hot water cylinder has malfunctioned or become obsolete in some way, then you naturally want to replace it with some affordable and effective. With energy and heating costs growing year on year, its makes sense that everyday families are on the lookout for something they can depend on reliably for a long time and that will minimise the cost of running it.

If your unit had suddenly broken down, it can be tempting to replace it with the exact same thing just so you can get back to enjoying showers like you used to. However, if you are patient and do your research you may be able to find yourself and your family a much better deal on a unit that it probably less likely to break down on you.

The following will examine different hot water cylinders and their features that should influence whether or not you invest in them.

Why can’t you just buy the same model again?

Of course – you can. But do you really want to go with the same model of hot water cylinder that broke down on you? Just because it will be quicker to install the same unit to the existing connections doesn’t mean it is actually a more convenient solution and it end up draining more of your money in the long run.

It’s a good idea to investigate what your usage is like so that you can gauge what new model would be best for your home. Perhaps there are ways you and your family can limit your levels of everyday usage in the future so that you can use a cheaper model that is more environmentally friendly.

Electric hot water cylinders

  • Cheap to buy and to install, but they are the most expensive models to run over a long period as the draw directly from the main power grid.
  • If you are replacing with the same model of hot water cylinder, installation can take as little as a few hours.
  • Using a peak electricity system can be cheaper but has a bulkier tank as it needs to use what’s stored from overnight drawing. Also, your home may not have access to off-peak electricity which would make this model obsolete for you.
  • Can be set up either indoors or outdoors.

Solar hot water cylinders

  • Uses naturally occurring, free and abundant energy of the earth’s sun without producing any emissions.
  • The sun does not always behave predictably and thus power generation is never consistently guaranteed.
  • While it will use as much solar power as possible, these hot water cylinders will still draw from the main power grid when it needs to make up the difference to keep the contents hot on cloudy days.
  • They are expensive and time consuming when they are installed, but they will pay for themselves once they start being used.
