Buffer tanks store water for hot water heating systems, helping maintain flow through plumbing. A steel buffer tank provides one option, while buffer tank design depends on the heating system, available space and required storage.

A buffer tank is a storage tank that helps maintain a constant flow of water in your home. It stores extra water, which can be released into the plumbing system when needed. This ensures that you always have enough water available, even if there is a sudden demand for it. ArchiPro features the best buffer tanks in Australia from reputable and trusted suppliers.

Chilled water buffer tank

A chilled water buffer tank is a small, insulated container filled with water. It sits between the chiller and a larger buffer tank, which holds hot water.

Hot water buffer tank

Hot water buffer tanks are used to store hot water for use later on. They are especially helpful if you do not have an in-home boiler, or if you need large amounts of hot water heating in your home.

The advantages of high-quality buffer tanks

High-quality buffer tanks are essential when you’re thinking about upgrading your existing model or buying your first one. High quality buffer tanks are better at running longer and more efficiently compared to lower quality alternatives. If you’re looking to reduce your energy consumption, high quality buffer tanks have better insulation thickness and coverage, meaning a greater insulation effect reducing your overall heating costs. Better build materials also result in an increase in the lifespan of your buffer tank too making it a great return on investment.

How to choose a buffer tank that’s right for you

If you’re in the market for a buffer tank, some factors to keep in mind are size, type, and material. The size of your buffer tank will depend on what kind of work you do, how much space you have available and how much storage space you need. It’s important that your buffer tank is big enough for your needs but not too big for its own sake. You should also think about the heating systems you have in place such as an air to water heat pump or an electric water heater and which type of buffer tank is needed. You should also consider what material your buffer tank is made out of before buying it since this will affect how long it lasts over time. When sizing a system, a 1000l buffer tank should be assessed against its storage requirements and available space.

What size buffer tank do I need?

The standard buffer tank storage capacity is between 250L to 5000L. However, the size of a buffer tank in Australia depends on the volume of water in your plumbing system, and how far the water has to travel.

Where should a buffer tank be placed?

The ideal place for a buffer tank in Australia is in between your water heater and the rest of your home. That way, when you use hot water, it gets stored in the buffer tank until you need it. As the hot water is used, it's replaced by cold water from your supply line—which means that you have an endless supply of hot water at any time.

What is the difference between a buffer tank and an expansion tank?

Buffer tanks are different from expansion tanks because they're designed to store energy rather than just maintain a constant pressure level. Expansion tanks are designed to prevent flooding in case something happens to cause a dramatic change in pressure (like turning off a tap).
