The different types of hot water systems

A hot water system in a home is one of those unnoticed appliances that have become very essential to our day-to-day lives. We rely on them for all the hot water supply in our homes. If you are planning on replacing your hot water system, you should know that there are various types in the market. These are the four main types of hot water systems you can choose from:

1. Electric Hot Water System

Electric storage systems use a heating element located inside a tank to heat water, similar to the way an electric kettle works. Water is heated and stored in the tank, available in various sizes, where it is kept hot and ready to be used. Here are some of the major pros and cons of an electric hot water system:

Pros

  • They have a low upfront cost
  • Convenient and easy to use
  • Produces hot water on demand
  • Brilliant choice for a family that uses a moderate amount of hot water
  • Does not require a lot for space

Cons

  • Can end up being expensive in the long run
  • Longer time recovery
  • No hot water during a power outage

 

2. Gas Hot Water System

A gas hot water system is a water heating system where the main fuel used is gas. Hot water systems that use gas haven’t been as common in Australia traditionally as the humble electric tank, although that is starting to change as the gas grid has expanded and modern style electronic ignition continuous flow water heaters that have features like touch pad temperature control have now evolved .

Gas hot water systems are great for large families because of their high recovery rate or rapid heating. The amount of water that they can heat to a certain temperature is higher compared to an electric water heater. In fact, it has been proven that they can heat twice as fast as the electric hot water heater system.

If you are connected to the natural or LPG gas, then you should consider getting a gas hot water installation. There are two main types of this water heater: gas continuous flow and gas hot water storage tanks.

Here are the key pros and cons of a gas hot water system:

Pros

  • High recovery rate or rapid heating
  • Ability to supply hot water even during a power outage
  • Low cost of operation
  • Limitless hot water

Cons

  • Higher initial cost
  • Risk of explosion

 

3. Solar Hot Heater System

With global warming becoming a real threat to the planet, eco-friendly solutions are being advocated to lower greenhouse gas emissions. Solar hot water system are one of the best examples of eco-friendly solutions in water heating. The system is powered by solar energy that is freely available and renewable.

Pros

  • They have a low running cost in the long run
  • Easy to use
  • High efficiency
  • You are able to get government rebates for renewable energy

Cons

  • Higher initial cost
  • Require sufficient roof space
  • Cold season or low levels of sunshine can affect it

 

4. Heat Pump Water Heater

Heat pump water heaters use a small amount of electricity to move heat from one place to another, rather than generating heat directly. To heat water, a heat pump works like a refrigerator in reverse. There are different types of heat pump systems but the most common type are when the evaporator absorbs whatever heat energy is available from the air and vaporises the refrigerant. This vapour is then compressed raising its pressure and temperature. Cold water from the storage tank is now pumped through the evaporator heat exchanger with the now heated water returning back to the storage cylinder.

Compared to a conventional electric water heater, a heat pump is more energy efficient and draws less power. 

Pros

  • High efficiency
  • Very low running costs
  • Great for a large family
  • Longer lifespan

Cons

  • Higher upfront cost
  • Requires good ventilation
