Boiler - calculate time and power supply of water heating in water tank.

You can switch to mode by radiobuttons:

- calculate time of water heating in hours and minutes

- calculate power requirement in kW

- you can check "F/US Gallon" for input data in °F instead of Celsia degree and volume of tank in US gallons instead litres 

Description:

- input temperature of water (minimum +5°C or +41°F)

- output temperature at what temperature the water warmed want (maximum +100°C or +212°F)

- efficiency in % .. what is the efficiency of the device (90% - very good thermal insulation , 10% very poor thermal insulation of tank)

- volume ... volume of tank in liters or U.S. gallons = 3.78541178 liters

- energy input .... appliance power in kW (wattage appliances of device)

Example:

In tank is 21 gallons (volume) of water 41°F (input). We need to warm up water to 131°F (output).

Heating element have power 2 kW (energy input).

How long time will it take?

- you have to check box  "°F/US Gallon" (if using US units)

- put data into correct edit fields 

- pres OK
