Are you a heating engineer or DIYer looking to size a radiator for a room?
This easy to use app lets you enter the details for a room, with dimensions in metres or feet, and it will then will calculate the heatloss in Watts and BTUs per hour. The desired room temperatures (12 - 24°C) can be set in the settings page and also the outside temperature (-10 to +5°C) the temperatures are also listed in their Fahrenheit equivalents.
The results will show:
• Ventilation heatloss - Losses from air passing through the room.
• Fabric heatloss - Losses through walls, floor and ceiling.
• Total heatloss - Sum of the ventilation and fabric losses.
The required radiator for the room can then be determined from the total room heat loss i.e. select a radiator that's rated higher!
The app can also be used to work out how much could be saved by fitting double glazing, cavity insulation or extra loft insulation to your home. Carry out a survey of each room in your house, with and without the double glazing/cavity insulation/loft insulation, then total the differences for the whole house to find how much heat is being wasted.
The app will also calculate the time taken to heat the room from the set outside temperature if the right radiator is fitted. You can enter flow and return rates and the Mean Water Temperature (MWT) and Delta T will be calculated, making it easier for you to select the right radiator.
If you like this app then please purchase the full version which has the following extra features:
1. Extra calculator to find the power of an existing radiator.
2. Email the results from either calculator to any destination.
3. No ads.
For only £1.50!
