Heating and Natural Gas: Pipe Sizing, Pressure Drop and Cost Calculations 4+

If you are a heating, cooling or natural gas services professional, these apps should make your life a bit easier.

This app bundle enables you to:

- Perform pipe sizing and pressure drop calculations for heating, cooling and natural gas installations;
- Calculate characteristics of underfloor heating systems;
- Perform sizing of a hydraulic separator for hydronic heating or cooling:
- Calculate cost of heating for different heating sources, including heat pumps, gas, oil, firewood, pellet and wood chip boilers.

Apps included:

1. Natural Gas Pipe Size

Estimate required pipe diameter for natural gas piping and installations in an instant. Calculate pressure drop for the selected pipe section.

Minimal user input is required (heat output of the burner and pipe length) and the result is instantaneous and accurate.

Wide range of conditions supported: gas lower heating value, temperature, pressure, location altitude can be set.

After a quick estimate of the recommended standard or nominal pipe size, the user can choose their own diameter, customize pipe material and define fittings and valves to calculate volume flow rate, velocity and pressure drop.

Metric and imperial units are supported.

Note: the application displays results for a pipe section. Calculations for multiple pipe sections should be performed separately.

2. Heating Pipe Size

Estimate required pipe diameter of a closed hydronic heating or cooling system in an instant.

Enter the required heating output, flow and return temperatures. Choose pipe material. The recommended pipe diameter is immediately presented as a standard DN.

Additionally, choose a pipe diameter and specify pipe section length and fittings. Results include water flow rate, velocity, pressure drop and can be used to determine the parameters of a circulation pump.

Note: only metric units are supported.

3. Hydraulic Separator

A hydraulic separator is used to separate primary and secondary circuits in heating and cooling systems. It is widely used in combination with gas boilers and heat pumps with integrated circulating pumps.

Correctly size a hydraulic separator in an instant. Two input parameters need to be specified: heat output and the smallest temperature difference required in the heating system.

4. Floor Heating

Determine the required water temperature, number of pipe loops, heat losses and more parameters of a hydronic underfloor heating system.

Floor Heating application makes it easy to design and understand hydronic underfloor heating systems.
The app is suitable for calculation of hydronic underfloor heating systems with pipes laid in a screed layer below floor covering, and can be used for a wide range of conditions: small or large systems, different floor coverings, different room locations, different insulation thicknesses and conductivities etc.

Modern low-energy and passive houses require lower water temperatures than buildings with poor thermal insulation. This application will help determine just how low.

Notes:
- metric units only;
- the application does not offer graphical layout of pipes;

5. Heating Cost

Estimate yearly heating costs when replacing existing heating generator (boiler) with a new one and compare heating costs for different heating sources/generators.

Heating sources / generators covered:
- heating oil (boilers with or without condensation),
- natural gas (boilers with or without condensation),
- LPG (boilers with or without condensation),
- firewood,
- wood chips,
- pellets,
- electricity,
- heat pumps.

Notes:
- metric units only;
- works only for existing heating generator replacement. Calculation is based on current system consumption.
