## Commercial Gas Calculator Description
This quick and simple-to-use app will assist gas engineers in calculating the maximum time required to purge air from a non-domestic natural gas installation, allowing the appliances to fire correctly.

Suitable for natural gas (NG) installations only, with an installation volume not exceeding 1m³, and a maximum operating pressure (MOP) not exceeding 40mbar at the outlet of the primary meter regulator. Calculations are performed in accordance with IGE/UP/1A and are intended to help you double-check your own calculations.

If you also require the tightness testing duration (TTD) for the system, the option to calculate this is available to purchase in-app.

For the busy multi-client gas professional, there's an option to purchase a Save Installations add-on allowing you to save and retrieve installation layouts for future reference.

## Commercial Gas Calculator Reviews in Vereinigtes Königreich

### *---- "Absolute rubbish"
Doesn’t do anything lets you put measurements in then wont add to system tried on iPhone and ipad same results zero
-- trricky rick, 2025-07-24

### ***-- "Could be better"
Would be a lot better and more useful if it was made useable for UP1 as well
-- GreenYamoChop, 2023-01-12

### **--- "Hose size on the purge makes no difference"
Very disappointed to see that the purge time remains the same for a 15mm purge point as it does a 50mm 
Something very wrong here hey
-- honest help, 2021-01-07

### **--- "Seriously lacking"
This is fine for domestic and medium-sized commercial installations, but where it falls short is on calculations involving larger internal volumes.  I find that once you get up to about 1.8 cubic meters or above, it simply errors and does not give purge and test times at all.

Furthermore the steel pipe sizes (a) are given in mm when steel is always measured imperially - in inches and fractions (b) only goes up to 150mm - six inches - when eight inch, twelve and above are common.

Disappointing app that really could be indispensable with these small changes.
-- ColinRTM, 2020-09-27

### *---- "Could be so much better"
Yes the calculator gives TTD but the calculations above do no indicate IVmeter so does not give IV to total 
I expected the calculator to allow for maximum permissible leak rates, but sadly it just works out the purge volume and TTD although given i had to manually work out to see if it was correct 
NO TTP nor let by period 
Unfortunately the app is sadly lacking however it does work out the pipe volume correctly !
-- Peter0047, 2020-03-15

### *---- "Not Great."
Does not offer standard UK sizes for pipework or even press systems. 

No 35mm, 54mm, 66.7mm etc etc

Update, 

I was referring to press systems, Mapress, Xpress, M-Press etc etc 

What about Stainless or Carbon Press? Copper and barrel are old hat these days
-- .......................dd, 2020-03-09

### *---- "Dangerously inaccurate"
Bought this in the hope that all the other reviews were wrong and somehow it would be ok for me, tested it on a tightness test that I had already calculated, true system volume was 0.95xxxm3, the app came out with 0.85xxxm3 and said the test time would be..... 2 minutes!!!!
-- Mr stauf, 2019-12-19

### *---- "RIP OFF!!"
Load of rubbish!!!! Will be asking for my money back!!! Not paying every time I want a calculation! Much rather pay £50.00 for one that works every time and not charge for the results each time! Do not buy!! It’s a scam! They don’t tell you that you need to pay for each result!!
-- demonboy13020, 2019-12-18

### **--- "Wrong calculations"
Was a good app when I bought it until I realised the calculations were somehow wrong. 

I worked one out today using the book (did it three times) & came out as 191 second purge time where as this app said 94 seconds ! Be using the trusted book next time !
-- rickblayke, 2019-11-14

### *---- "Very carefully not good apps"
Dear buyers be careful from this apps because not good at all. I Used this apps for couple weeks suddenly I realised the calculation is in correct. From now I am using my book.
