Closed System Testing Analysis

 

Regularly testing your closed heating or cooling system for microbiological and chemistry levels ensures your system is under control and is a preventative task that helps reduce risk of system failure, corrosion, scale, poor flow and bacterial growth. All of which can help reduce large bills to repair inevitable system failures if no testing is carried out. Such testing can help identify sufficient chemical inhibitor levels such as Molybdate and Nitrite. 

uRisk is a nationwide water hygiene company with City and Guilds trained engineers who have experience in industrial, commercial and domestic heating and cooling systems.

How often should I Test my Closed System?

 

Closed System Testing frequency is carried out every 3 months (quarterly) or when a system has changed where there is new or additional pipework.

How long does Closed System Testing take?

 

Closed System Testing can take up to 1 hour depending on the design and heating system you have installed.

What happens after the Closed System Testing Results

 

Once you receive you Closed System Testing Results you will be advised on the next steps to take. In most instances you will be advised to have your system dosed with either inhibitor and/or biocide. You may also be advised that further Closed System Testing is required to interpret how the inhibitor and/or biocide has impacted your system.

How much does Closed System Testing cost?

 

Closed System Testing prices may vary depending on the size, quantity of your systems and site requirements, but industry prices generally range between £100 to £400 per system test.

How to make my Heating System or Cooling System more Efficient?

 

New systems are often higher more efficient systems heating systems and cooling systems due to technology upgrades. But how do we keep our heating systems and cooling systems efficient; and how do we make old and existing heating systems and cooling systems last longer?

Preventative monitoring and servicing can play an important role in avoiding large bills for faults and replacement costs for heating and cooling systems. Below are just a few ways you can avoid those unwanted expensive bills:

  • Designed correctly and fit for purpose
  • Installed correctly
  • Cleaned & commissioned correctly
  • Maintained correctly

Failure to ensure any one of these 4 items will results in poor system performance, a reduce system lifetime and more expenses.

What happens if I do not treat my Closed System?

 

Systems that are not treated at least annually (commercial systems bi-annually) will begin to suffer from scale, corrosion, and gassing can occur as well as the potential for microbiological proliferation. System efficiency can see up to 30-40% reduction in system efficiency on sludgy and fouled systems.
