Overview

The WT-V Accumulator tanks are designed to store heated water, typically for use in heating systems. These tanks are essential components in systems where a heat pump or other heat source generates heat that needs to be stored for later distribution, ensuring a stable and efficient supply of heating or hot water. The design focuses on robust construction and efficient heat retention to maximize energy savings and system performance.

Function Description

The primary function of the WT-V Accumulator tanks is to act as a buffer storage for heated water. This allows the heat source, such as a heat pump, to operate at optimal efficiency by running for longer periods and storing excess heat rather than cycling on and off frequently. When there is a demand for heat in the building, the stored hot water from the accumulator tank is circulated through the heating system. This decoupling of heat generation from heat demand contributes to a more stable indoor climate and reduces wear and tear on the heat source. The tanks are designed to maintain the water temperature effectively, minimizing heat loss to the surroundings. Connections are provided for various system components, including the heat source, heating circuits, temperature sensors, and expansion/venting lines, allowing for flexible integration into different heating setups. Some models also feature connections for immersion heaters, providing an auxiliary heat source if needed.

Usage Features

The WT-V Accumulator tanks are designed for straightforward installation and integration into existing or new heating systems. Before connection and filling, the tank must be placed on a solid, level surface. Some models are equipped with setscrews for precise leveling, while others may require shims. This initial leveling is crucial for proper operation and stability. Once leveled, the tank can be connected to the piping system. Any unused connections should be properly plugged to prevent leaks and ensure system integrity. During the initial filling with water, condensation may form on the outside of the tank, which is a normal occurrence and will cease once the tank heats up. It is important to ensure a floor drain is present in the same room to manage any potential water spills or condensation.

For situations requiring the temporary removal of insulation, such as navigating narrow passages during installation, specific instructions are provided. This involves removing Torx 10 screws that secure the locks at the top and bottom, flipping the locks, and then removing the remaining screws along the side. The insulation also features Velcro on the inside for easy reattachment. This feature highlights the modularity and serviceability of the tank's design.

Commissioning involves filling the tank and then pressurizing it, followed by filling the entire radiator system. It is critical to ensure that the working pressure does not exceed the specified test pressure, and a safety valve with an appropriate release pressure must always be installed as a safety measure.

Maintenance Features

Maintenance of the WT-V Accumulator tanks is designed to be simple and regular to ensure long-term reliability and safety. An annual check of the safety valve is recommended. This involves manually opening and closing the valve handle to confirm that water is released, indicating proper function. Additionally, all connections, including those of peripheral installations like a heat pump, should be checked annually for any signs of leakage. This proactive approach helps identify and address potential issues before they escalate, ensuring the system operates efficiently and safely.

The electrical installation associated with the accumulator tank must be carried out by an authorized installer, adhering to all applicable norms and regulations. When selecting electrical equipment, it is essential to choose approved materials and ensure the correct enclosure class for safety and compliance.

For the eventual disassembly of the product, it is important to observe all applicable laws and regulations. Users are advised to contact their installer for detailed information and guidance on proper disposal and recycling procedures, emphasizing environmental responsibility.
