This app doesn’t work with the latest iOS update tho:( So please EOGB can you update it so it can be used with the latest version of iOS! YES ,just got the update. THANK YOU EOGB! ### 4/5 — Great app until OS11 *2017-12-07, version 1.5* Shame that EOGB haven’t bothered to update the app. We all used this so much which helps a lot in the field when selecting Burners oil nozzles. As a paid for app this is shameful really. App makers were warned long ago about transferring from 32bit tech to 64bit tech final killing 32bit in OS11. ### 5/5 — Nozzle Calculator *2012-04-13, version 1.1* Highly recommended for any oil technician who prides in getting it right. I have been at it 5 years now and find this very helpful for getting the right nozzle for the right output. Wish OFTEC would come on board and recommend this during training. Thanks EOGB. ### 4/5 — Ok *2012-03-16, version 1.0* How come there isn't an option for 1.25? Fairly common nozzle I would say. ### 5/5 — Great Idea *2012-03-05, version 1.0* Brilliant app, wished I had found it years ago! ### 5/5 — Mack *2012-02-29, version 1.0* Long overdue. Makes calculating so much easier and quicker. Will definitely recommend this app. Excellent for calculating when boilers have no identification. ### 5/5 — Extremely useful *2012-02-22, version 1.0* Brilliant app, very handy to have as a tool, saves a lot of time working things out on site and I found it especially useful setting up when a change of fuel type is being implemented.would be useful to have a KW-BTU option on an update but that said I will certainly be recommending this app. Thank you EOGB!! ### 5/5 — Excellent idea *2012-01-29, version 1.0* Very useful app, particularly useful on older appliances and commercial boilers when no data is available.The efficiency scale is good as you can change to suit appliances plus the eh/es to h/s is of use selecting an alternative nozzle.Thanks ## Frequently asked questions about Oil Nozzle Output Calculator ### What is the Oil Nozzle Output Calculator used for?
