Electric Safety Tests
The app will show you how to carry out all of the tests from start to finish to help you make sure the boiler is completely safe. The tests should be carried out after an installation (before switching on the appliance) and also before carrying out any work on an existing boiler. Many electrical faults can be identified from the tests. Each test contains easy to understand images to make it much simpler to follow.

Use the Gas Ratio Calculator to process the results from your Gas Flue Analyser and find the CO/CO2 ratio for natural gas. If the boiler is running efficiently there may be no need to service it. Simply test the boiler with your analyser and obtain the oxygen, carbon monoxide and carbon dioxide values.
Input the values from the analyser into the Gas Ratio Calculator, the CO/CO2 ratio will be calculated and advice also given on whether the boiler should be serviced or not.

Gas Rate Calculator Android App
Try Mr Combi's Gas Rate Calculator!
Use the Gas Rate Calculator to find hourly gas rates, gross heat inputs and net heat inputs in BTUs per hour and kW. Metric and imperial calculators for natural gas, butane and propane.
Calorific values can be entered manually for more accurate results. The calorific value of natural gas in the UK varies from about 38.3 to 40.5 MJ per cubic metre; this can mean a difference in the gas rate calculation of more than 5%! With this calculator you can add the CV for your area in the settings page and avoid these inaccuracies.
The metric timer can be set to either 1 or 2 minutes. For U6 and G4 meters one minute is sufficient, for E6 meters two minutes is recommended for accuracy. The timer can be set to an audible alert, vibrate, both or neither.
A torch function is included with this app if your device has an LED flash.
