## Overview

The Duda Solar ExpTank-008V-S is an 8-liter red expansion tank designed for solar water heater systems, featuring a high-temperature resistant EPDM membrane made in Italy. It supports up to 10 bar pressure and 130°C fluid temperature, ensuring reliable thermal pressure protection. Certified for hygiene and safety, its robust steel construction and precise sizing make it essential for maintaining system stability and preventing pressure-related failures.

## Description

Expansion tanks are essential for solar water heater systems. The Red expansion tank is used for relieving pressure build-up in the closed loop system. This helps keep the pressure consistent and relieve pressure from the piping as the working fluid increases in temperature. Should the solar system go into overheat mode and shut down the circulation pump, the expansion tank is essential for preventing the pressure valve from blowing out the working fluid. The Red Duda Solar expansion tank is fitted with a special high temperature EPDM membrane made in Italy which can withstand the high temperatures of the solar systems. The size of the expansion tank needed depends on the total amount of fluid used in the closed loop (maximum possible volume). Some data regarding common fluid volumes in the solar systems is in the chart below. As an example, a standard 300 liter solar system has a 30 tube collector, 100 feet of 1/2" stainless steel tubing and a 300 liter tank (25m coil) for a total of ~7 liters of fluid volume, requiring at least an 8 Liter expansion tank.

### ⭐⭐⭐⭐ 







  
  
    Good basic tank
  

*by A***N on Reviewed in Canada on 16 July 2020*

Well built, replaceable bladder if you can find one, works well. I almost give it two thumbs up.My only complaint is that the BesTank datasheet says 1" fitting. True, sort of, it is a 3/4NPS (a 1" straight thread instead of the usual 3/4NPT tapered thread). Finally found the fitting at McMaster-Carr, their part number 5372K223. Would have been nice to have been told what type of thread it was.
