Hot water systems come in all shapes and sizes, but there are three main types that homes in Australia typically use. Suppose you’re trying to decide which hot water system is best for your home. In that case, it’s important to understand the differences between them. In this blog post, we’ll take a closer look at each type of system and discuss some of the pros and cons of each option. Read on to learn more!
The main types of hot water systems
The hot water system is one of the most important inventions of the modern world. It allows us to heat water to high temperatures, making it safe for use in various settings. The first hot water systems were developed in the early 19th century and have been evolving. Today, there are various hot water system types available, each with its own set of benefits and drawbacks. However, all hot water systems share one common goal: to provide hot water. Let’s try to understand the main types of hot water systems available today.
Storage Tank water heaters
Storage tank water heaters are the most common hot water systems used today. They come in various sizes, from small 75-litre units to large tanks that can hold 375 litres or more. And they’re available in both electric and gas models.
How do they work? Simply put, storage tank water heaters work by heating water and then storing it in a tank until it’s needed. When hot water is called for—for a shower, dishwashing, laundry, etc.—it’s pulled from the top of the tank, and hot water is drawn up from the bottom to replace it. The size of the hot water tank is important because it determines how much hot water will be available before the system needs to reheat the water. If you have a household of four people who all take showers every day, you’ll need a larger hot water tank than if it’s just you and your spouse taking showers. The same goes if you have a lot of visitors or if you entertain often and need to do lots of cooking and dishwashing.
There are several advantages and disadvantages associated with this type of appliance. Some of the pros of a storage water heater include the fact that they are relatively inexpensive installation cost, efficient, easy to maintain, and safe. Additionally, storage water heaters are often quite readily available. Some of the cons associated with storage water heaters include heat loss, difficulty in operating, heating vs. storing, and the fact that they can be bulky. Overall, the pros and cons of a storage water heater should be carefully considered before deciding whether to install one in your home.
on-demand or continuous flow water heater
A continuous flow hot water system, also known as a tankless hot water heater, is a type of hot water system that does not rely on a storage tank of hot water. Instead, it heats water on demand as it is needed. This means that you will never run out of hot water as long as there is a sufficient supply of cold water. Continuous flow hot water systems are powered by either gas or electricity, and they come in a variety of sizes to suit different needs. Generally speaking, they are more energy-efficient than storage hot water systems, as they only heat the water that you need when you need it.
Tankless water heaters have grown in popularity in recent years due to their compact size, energy efficiency, and design flexibility. However, there are some drawbacks to tankless water heaters that should be considered before making a purchase. Tankless water heaters cannot store hot water, so if there is a sudden water service interruption, you may not have any hot water. Additionally, tankless water heaters can have inconsistent temperatures, meaning that the hot water may not be consistent from one tap to the next. Despite these drawbacks, tankless water heaters have many benefits. They can be an excellent choice for homeowners looking for an energy-efficient and space-saving hot water solution.
Solar water heaters
A solar water heater is a hot water system that uses solar energy to heat water. Solar water heaters are typically used in residential and commercial applications. There are two types of solar water heaters: active and passive. Active solar water heaters use pumps or fans to circulate the water through the solar collector. In contrast, passive solar water heaters rely on gravity and convection to circulate the water. Solar water heaters are typically more efficient than conventional hot water systems. They can save up to 80% on hot water costs.
Solar water heaters use the sun’s energy to heat water, which means they don’t produce any greenhouse gases. Solar water heaters are also easy to maintain and quiet but prone to corrosion issues and could become an added burden to your roof, weight wise. The initial cost of solar water heaters can be expensive, but they will eventually pay for themselves. Solar water heaters are a great option for people who want to reduce their carbon footprint. However, solar water heaters only work in good weather as a storm may block its energy supply, and they can’t be used to power other electrical devices as opposed to solar panels that could power other appliances.
