Thermal-Plus Tanks: Safeguarding Your Hot Water System

The Thermal-Plus pressure tank from Aquasky is a high-tech solution designed to address the challenges of thermal expansion in modern water heating systems. This essential device is engineered to prevent excessive pressure build-up, protect plumbing components, and extend the overall lifespan of water heaters. Aquasky Thermal-Plus expansion tank ensures that your system operates safely and efficiently.

1. Introduction to Thermal-Plus Expansion Tank

What is water expansion?

When water is heated, it expands in volume. For example, heating water from 30°C to 80°C in a 180-liter tank can cause an expansion of nearly 6 liters. Because water is incompressible, this additional volume must be accommodated to prevent pressure from reaching dangerous levels.

In a home water heater, when a full tank of water is heated, it may require more space than the tank can provide. If the expanding water has nowhere to go, it will build pressure, which can damage valves and even rupture household plumbing, significantly shortening the lifespan of the water heater. Every home with a tank-type water heater faces this challenge.

What is thermal expansion tank?

Since 1990 municipalities have been installing backflow preventers within water systems to prevfent water from flowing back into the main supply. This change has turned open-loop systems into closed-loop systems, creating the need for thermal expansion tanks to provide a place for the expanded water to go in closed systems.

A thermal expansion tank is a safety device designed to minimize the risk of pressure damage to the plumbing system. In a closed-loop domestic water heating system, as cold water is heated, it expands, leading to an increase in both volume and pressure within the system. The thermal expansion tank serves as an overflow receptacle by absorbing the excess water volume created by the water heater, thereby preventing pressure from reaching dangerous levels.

Aquasky Thermal-Plus expansion tank

In response to this need, Aquasky created the Thermal-Plus expansion tank series to effectively absorb expanded water in closed hot water systems. By maintaining a dedicated reservoir for the expanded water, these tanks help manage the increased volume and pressure, ensuring the safety and efficiency of the water heating system. The Aquasky Thermal-Plus expansion tank is engineered to provide a reliable solution to the challenges of thermal expansion, protecting your plumbing components and extending the lifespan of your water heater.

2. Design and Features of Thermal-Plus Expansion Tank of Aquasky

Aquasky Thermal-Plus expansion tanks feature robust construction and advanced materials to ensure durability and longevity, even in challenging conditions.

Exterior:

* The shell of the Thermal-Plus expansion tank is built with cold-rolled carbon steel, providing excellent strength and the ability to withstand high pressure.

* Each tank is equipped with a stainless steel system connection.

* The exterior is coated with a three-layer rust-resistant, appliance-grade finish. For standard Thermal-Plus series, the triple-grade almond (RAL1015) coat distinguishes it from other series.

Interior:

* Inside the tank, a flexible diaphragm made from butyl rubber - known for its superior air resistance - separates the water from an air cushion. This diaphragm is engineered for maximum flexibility and durability, capable of withstanding temperatures up to 90°C and repeated pressure cycles without degrading.

* The diaphragm divides the tank into two chambers: an air chamber and a water chamber.

* An additional layer of FDA-approved polypropylene lines the water chamber. This liner prevents the water from coming into direct contact with the tank shell, protecting the shell from corrosion and maintaining water quality.

This careful selection of materials ensures the tank can handle frequent pressure changes while maintaining its integrity over time.

4. How Thermal-Plus Tanks Work

Thermal-Plus expansion tanks play a critical role in maintaining the safety and efficiency of closed-loop water heating systems. Here's a detailed at how they operate:

* When the water heater turns on and begins to heat the water, the water expands. In a closed system, this expansion is absorbed by the thermal expansion tank.

* When the expanding water enters the tank, it pushes against the diaphragm, compressing the air on the other side. This compression increases the air pressure inside the tank, which counteracts the pressure in the water system, maintaining equilibrium. The expanded water is temporarily stored in the tank, preventing it from increasing the pressure in the main water heater and plumbing system. This balance ensures safe pressure levels.

* When a faucet is opened or a shower is turned on, the pressure in the system decreases. The compressed air in the tank pushes the diaphragm back up, sending the stored water back into the main system. This dynamic response to pressure changes ensures that the system remains safe and efficient, even during significant temperature fluctuations.

This continuous process of absorbing and releasing expanded water helps maintain a balanced pressure within the water heating system. It prevents dripping valves, relief valve discharges, and other potentially hazardous conditions caused by excessive pressure.

In a closed-loop domestic water system, which may include a backflow preventer, water meter with a check valve, or other non-return valve, the Thermal-Plus expansion tank works in conjunction with these components. Once attached to the cold water inlet of the water heater, it controls excessive pressure generated as water heats and expands. By providing a dedicated space for the expanded water, the tank prevents pressure from rising to harmful levels. This ensures balanced system pressure, preserving the integrity of the water heater and plumbing, and maintaining safe operation in your home.

5. Installation Tips for Thermal-Plus Tanks

Installing a Thermal-Plus tank involves several steps to ensure proper functioning:

* Position: Install the expansion tank on the incoming water line to the water heater, between the water heater and the backflow preventer or check valve.

* Location: Choose an appropriate location near the water heater to minimize pipe length and potential heat loss. Ensure the area is accessible for future maintenance. Select a location with proper water drainage to prevent property damage in case of leaks.

* Connection: Use the correct fittings and connectors to attach the tank to your plumbing system. Flexible connectors are recommended to accommodate any movement or vibrations.

* Pressure Setting: Adjust the pre-charge pressure in the tank to match your system’s operating pressure. This step is crucial for optimal performance and can usually be done using a standard air pump.

* Testing: After installation, test the system to ensure there are no leaks at the connections and that the tank is effectively absorbing the pressure increase.
