How to Specify Ridgeline for New Builds, Retrofits and Heat Pump Projects

Step 1: Define The Application

Start by identifying the role of each run:

• hot water distribution
• cold water distribution
• central heating flow and return
• air source heat pump flow and return
• plant room or cylinder connections
• underfloor heating
• final connections through Flexis

Do not specify by material alone. Specify by application and system role.

Step 2: Select The Tube And Size

Use the Ridgeline data sheets and technical support to choose the correct size for the flow requirement, pressure drop, route length and temperature.

For heat-pump applications, sizing should be checked against the heat-pump design. Heat pumps often need careful flow-rate and pressure-drop control.

Step 3: Define The Connection System

Ridgeline tube works with dedicated Ridgeline connection technology. The specification should state the fitting system and any compatibility requirements clearly.

Avoid vague language such as "connect to suit". It invites substitutions and creates confusion on site.

Step 4: Control Hidden Fittings

Where pipework is concealed, specify continuous runs where practical and keep connections accessible where possible.

Suggested wording:

Concealed pipe routes should use continuous Ridgeline 316L stainless steel tube runs where practical, with fittings located in accessible zones unless the manufacturer's instructions and project design permit otherwise.

Step 5: Include Proof Documents

Every specification should link to:

• product data sheet
• installation instructions
• approval certificates
• pressure and temperature data
• fitting compatibility guidance
• warranty information

This helps contractors price accurately and avoids substitution by assumption.
