Expansion Vessel Bracket Overview


What Is an Expansion Vessel Bracket

You use an expansion vessel bracket to hold a thermal expansion tank in place. This bracket attaches to a wall or another solid surface. It keeps the thermal expansion tank steady so it does not move or fall. When water heats up in your plumbing system, it expands. The thermal expansion tank absorbs this extra pressure. The expansion vessel bracket supports the tank and helps it do its job. You find these brackets in homes, schools, and large buildings. They come in different shapes and sizes to fit many types of thermal expansion tanks. Some brackets work best for small tanks, while others support heavy tanks in big systems.

Tip: Always choose a bracket that matches the size and weight of your thermal expansion tank. This helps keep your system safe.

Why Proper Support Matters

Proper support for your thermal expansion tank is very important. When you use the right expansion vessel bracket, you protect your system from leaks and damage. The bracket keeps the tank in the correct position. This helps the thermal expansion tank control pressure changes caused by expansion. If you do not use a strong bracket, the tank might shift or fall. This can cause pipes to burst or water to leak. You also help your system last longer by using the right support.

  • The expansion vessel bracket:

    • Controls thermal expansion by holding the tank steady.

    • Maintains stable pressure in your system.

    • Prevents damage to pipes and stops leaks.

    • Keeps your heating and plumbing system safe.

    • Helps you follow safety codes and standards.

You need to check your expansion vessel bracket often. Make sure it stays tight and free from rust. A good bracket helps your thermal expansion tank work well every day.

Floor and Leg Supports

Sometimes you need to put the thermal expansion tank on the floor. Floor and leg supports help keep the tank steady and upright. You use these for bigger tanks or when there is no wall space. Easywell makes strong supports for commercial boiler rooms and big HVAC systems. The steel is tough and does not rust. These supports hold heavy tanks. You can use them where there is vibration or movement. Rubber pads help lower noise and stop the tank from wearing out.

Bowed, Round, and Square Brackets

You pick bowed, round, or square brackets based on your space and needs. Bowed brackets save space and fit in small areas. Their sealed design works well in wet places and stops rust. Heavy-duty bowed brackets are good for factories. These brackets are small, so you can use them in tight spots.

Round brackets have parts you can change and adjust. Most standard tanks fit in these brackets. The design spreads weight evenly and keeps the tank stable. Lab tests show round brackets lower stress by 30%. You get a 5-year warranty for the coating. This means the bracket will last.

Square brackets are best for small hydronic systems. They give a strong and steady base for the thermal expansion tank. You see these brackets in homes and businesses.

  • Space-saving design uses strong steel tubes for heavy tanks.

  • The finish and topcoat protect against rust for over 10 years inside.

  • Rubber pads lower noise and stop tank wear.

  • You can install tanks up or sideways with adjustable plates.

  • All designs meet EN 13816 and ASME BPVC Section VIII safety rules.

Adjustable and Universal Brackets

Pressure Vessel Supports

Lug, Skirt, and Saddle Supports

There are a few main types of supports for pressure vessels. The most common ones are lug, skirt, and saddle supports. Each support works best for certain shapes and sizes. You can see how they are different in the table below:

Support Type

Typical Application

Load Distribution Characteristics

Effect on Vessel Stresses

Skirt Support

Tall vertical columns

Loads spread over a shell welded to the vessel bottom; handles many loads

Minimal local stresses at the junction; good for many loads

Lug Support

Medium height vessels

Eccentrically attached; causes bending moments and local stresses

Induces bending, compressive, tensile, and shear stresses

Saddle Support

Horizontal vessels

Loads spread over two or more cradles; placement affects load distribution

Minimizes stress concentrations using vessel head stiffening

Skirt supports are used for tall, vertical vessels like distillation columns. These supports hold up the vessel’s weight and stand up to wind. Lug supports are good for medium-sized vessels. They attach to the sides and can hang or sit on the floor. Saddle supports are made for horizontal vessels. Two saddles hold the vessel and spread out the weight. Saddles are often placed about one-fourth of the vessel’s length from each end. This helps the vessel heads make the vessel stronger and lowers stress.

Choosing the Right Support

When you pick pressure vessel supports, you need to think about the vessel’s shape and size. You also need to know where it will go. It is important to look at the parts that hold the weight and how they affect the vessel. Here are some key things to remember:

  • Material strength and corrosion resistance help supports last longer.

  • The way the vessel sits changes which support you need. Vertical vessels usually use skirts. Horizontal vessels use saddles.

  • Industry rules like ASME Section VIII and EN 13445-3 help with safe design.

  • How much space you have and how heavy the vessel is matter. Lug supports are good for small spaces or hanging vessels.

  • How easy it is to fix and make the support can change your choice.

Tip: Always make sure your support follows safety rules and fits your vessel. Good support keeps your system safe and helps it last longer.

The right support does more than just hold the vessel. It also keeps it safe from stress and damage. If you know about the different supports, you can pick the best one for your system.

Choosing a Bracket

Size and Weight Considerations

You must pick a bracket that matches your expansion vessel’s size and weight. If the bracket is too weak or small, it can break and cause problems. Always check how much the tank weighs when it is full, not just empty. Easywell has brackets for many tank sizes, from small home tanks to big commercial ones. Use the maker’s guide to find the right size. The right bracket keeps your system safe and steady.

Tip: Do not guess the size or weight. Always measure and follow the rules for your system.

Installation Environment

Where you put your bracket matters a lot. Some places have water, chemicals, or very hot or cold air. These things can make the bracket rust or get weak. You should pick materials that can handle these problems. For example:

  • Stainless steel is good in places with saltwater or strong chemicals.

  • Fiberglass-reinforced polyester does not get damaged by water or chemicals.

  • Epoxy or powder coating gives extra protection.

  • Aluminum is light but may need a coating for tough places.

The right material helps your bracket last longer and keeps your system safe. Always check what your area needs before you buy.

Compatibility and System Design

You need to make sure your bracket fits your system’s design and setup. The bracket should fit the tank and work with your pipes. Some systems need special ways to mount or extra support. Easywell has kits and adjustable brackets for different setups. Always look at your system’s needs before you choose.

Here is a simple checklist to help you pick the right bracket:

  1. Check the tank’s size and weight.

  2. Look at the area for water, chemicals, or extreme temperatures.

  3. Make sure the bracket fits your system’s design and setup.

  4. Pick a bracket with the right material and protection.

Bracket Installation

Bracket Installation


Tools and Preparation

Before you start the installation, gather all the tools and materials you need. This helps you work safely and finish the job without delays. Here is a checklist to guide you:

  1. Pipe cutter and pipe wrench

  2. Screwdriver set

  3. Drill with bits for your wall type

  4. Teflon tape or pipe thread sealant

  5. Bucket and towels for water spills

  6. Compatible expansion vessel and bracket

  7. New pipes or fittings if needed

Tip: Always turn off the power to electric heaters or shut off the gas supply for gas heaters before you begin. Shut off the water supply to the heater and release any pressure using the relief valve. This step keeps you safe and prevents water damage.

Choose a spot near the water heater, close to the hot water outlet. Make sure the area is clear and has enough space for the expansion vessel. You want at least 18 inches of clearance from any vent connector. If you replace an old tank, drain the system and remove the old tank carefully.

Mounting the Bracket

Proper installation and placement of the bracket are key for system safety and long-term performance. Start by marking the mounting location on a solid wall or support. Use a level to ensure the bracket sits straight. Drill holes for the mounting hardware. Easywell’s modular kits come with pre-drilled M8 holes and all the hardware you need, which makes the installation process faster and easier.

Mount the bracket vertically whenever possible. This position puts less stress on the fittings and keeps the tank stable. If you must mount the tank horizontally, add extra support to prevent movement. Secure the bracket tightly to the wall or support. Make sure it does not wobble or shift. Easywell’s modular kits allow you to adjust the height by up to 50mm, which helps when you retrofit older systems or work in tight spaces.

Note: Always choose a location that allows easy access for future maintenance and avoids areas with high heat.

Securing the Expansion Vessel

Once you have mounted the bracket, you can secure the expansion vessel. Attach the vessel to the bracket with the connection at the top. This vertical position reduces mechanical stress on the fittings. Use sturdy straps or clamps if your bracket design includes them. Connect the cold-water inlet pipe to one side of the vessel and the hot-water outlet pipe to the other. Apply Teflon tape or pipe thread sealant to all threaded connections to prevent leaks.

Add a lockable ball valve and a drain point near the vessel for easy isolation and maintenance. Install a pressure relief valve between the tank and the ball valve to protect the system from excess pressure. After you finish the connections, turn the water supply back on and check for leaks. Refill the system and bleed any air using the relief or bleed valves. Turn the heater or boiler back on and monitor the pressure to make sure it stays within safe limits.

Easywell’s modular kits fit most standard expansion tanks and include vibration-damping features. These features reduce noise and help the system last longer. The kits also come with clear manuals and 3D models to guide you through each step.

Safety Tips and Common Mistakes

You must follow safety steps during installation to protect yourself and your system. Here are some important tips:

  • Always turn off power, gas, and water before starting.

  • Wear gloves and safety glasses to protect your hands and eyes.

  • Use a sturdy ladder if you need to reach high places.

  • Double-check that the bracket is mounted on a solid surface, such as concrete, wood, or metal.

  • Do not mount the bracket on drywall alone, as it may not support the weight.

  • Make sure all connections are tight and leak-free before turning the system back on.

Common mistakes include mounting the bracket in the wrong position, using the wrong size bracket, or skipping the pressure relief valve. Avoid these errors to keep your system safe and efficient.

⚠️ Alert: Never rush the installation. Take your time to check each step. A careful installation helps prevent leaks, damage, and costly repairs.

When you use Easywell’s modular kits, you simplify the installation and reduce the risk of mistakes. The adjustable arms and pre-drilled holes save time and help you align the tank with precision. You get a stable, safe, and long-lasting support for your expansion vessel.
