### Pipe Volume

Dead Legs are the volume of water in a pipe branch.

### Pipe Velocity

Velocity is the average speed of a fluid travelling through a pipe.

### Pressure Drop

Pressure is the force required to move water through a pipe.

### Water Flow Rate

Flow Rate is the volume of water travelling through a pipe.

### Heat Loss

Calculate the loss of heat of a building, room by room.

### Gas Pipe Sizing

Gas is used to fuel heat elements within a building.

### Air Duct Velocity

Duct velocity represents the speed of airflow through a duct.

### Duct Sizing

Duct size is the dimensions for sufficient airflow in buildings.

### Ductulator

Easily calculate duct sizes and optimise HVAC designs.

##### CASE STUDIES
###### Award-Winning Heating Design

"Using h2x was pivotal, allowing for precise heat loss calculations, pipe sizing and flow rates for each room.

This level of detail ensured that the heating load accurately matched each space's requirements, minimising energy waste and maximising comfort.

The strategic placement of heat pumps and careful sizing of pipework were crucial in maintaining minimal pressure drops over an 18-metre distance."

##### CASE STUDIES
###### Greengate, UK

"I would estimate over the length of this project, I have spent 50% less time designing than I would on our previous software.

The ability to output the design straight into Revit assisted clash detection and coordination."

##### CASE STUDIES
###### Salon Republic, USA

"The quality of the designs saw significant improvement with the adoption of h2x."

"The software offers precision through detailed result outputs and advanced options for efficient pipe sizing, allowing heating engineers to optimise based on parameters like maximum velocity and pressure drop."
