A Simple Checklist On Purchasing A Hot Water System

If you’re unhappy with your home’s shower pressure, then it might be time to switch out your hot water tank or system. It can be hard to know which brand you should be going for or which brand will be the most suitable for your home. Indeed, a hot water tank is certainly one of the more popular choices and you’ll soon see why.  Like purchasing any item for your home, you need to have a clear and straightforward process that you stick to, regardless of whether the tank will be a brand new installation or replacing an old, outdated system. So, here’s what you need to remember.

Gas vs electric

One of the big dilemmas when purchasing hot water cylinders is whether to go with a gas option or an electric configuration. A gas system uses a gas burner to continually heat the liquid. One of the benefits of this is that it produces fewer emissions, meaning it is better for the environment. Simultaneously, because it is a gas-powered cylinder, it’s also a lot more energy efficient. You’ll see your energy bills fall in the long run and your aqua usage decrease!

Alternatively, a hot water system powered by electricity operates slightly differently. In essence, there is a heating element fixed at the bottom of the tank that completes the heating function. Firstly, an electric system is considered more reliable to maintain and cheaper to install (the initial price is lower as well). However, it is more expensive to run an electric hot water system in the long term because electric power is less energy efficient. Likewise, electric systems leak more greenhouse gas emissions, having a more negative effect on the environment.


Proximity of the unit

Another thing you need to consider is how far away the unit will be from your source. Heat loses energy the further it has to travel, so the further away your taps are from the unit, the less efficient your hot water system will be. Put simply, you’ll be burning more energy, more money and likely be having colder showers.

If your new system is too far away, you may have to look into having it moved to a different location or modify the pipes connected to your unit. You may require a separate flow on both sides of your home to ensure pressure remains constant, while not wasting valuable H20.


Size of family

When you need to purchase a hot water cylinder, you need to consider how many people will be using the unit. If you are living by yourself, you’ll only need a relatively small unit. Generally, one tank can sustain the needs of approximately three people, so it’s not until your living with more than four people that you’ll really need to consider whether you require a larger hot water storage tank. On a side note, you’ll also need to be thinking about how many outlets you have – taps, sinks and showers. The more you have, the larger your tank will need to be to ensure adequate distribution.


Available sizes

Hot water heaters come in a wide range of sizes. A stainless steel electric heater can range from 50L to up to 315L. The stainless steel also helps with durability by preventing rust. A generic electric cylinder can hold up to 400L, while the regular gas heaters are available in models holding 135L and 175L. The “stellar” gas models are equipped to hold 330L and 360L, making them perfect for larger families. It also comes with a 10 year cylinder warranty and boasts a 5 star energy efficiency rating.
