750mm ASHP Hose Pair 1″ Female x 28mm Pair | Kudos Trading

750mm ASHP Hose Pair 1″ Female x 28mm

Flexible Connections for Air Source Heat Pumps

Air source heat pumps can produce small amounts of vibration during normal operation.

Rigid pipework can transfer this movement into the building. Therefore, flexible hoses help isolate the outdoor unit from fixed heating pipework.

They also make the final connection easier. As a result, installers have more flexibility when aligning the heat pump with the system pipework.

Supplied as a Pair

Each pack contains two 750mm flexible hoses.

Therefore, one pack provides the connections needed for both flow and return pipework.

Supplying both hoses together also helps create a consistent installation around the outdoor unit.

1″ Female Swivel Connection

Each hose features a 1″ female swivel connection at the heat pump end.

The swivel design makes final connection easier. Therefore, installers do not need to rotate the entire hose while tightening the joint.

This feature can prove especially useful in restricted installation areas.

Straight Female Swivel Design

This version uses a straight 1″ female swivel connection.

Therefore, it suits installations where the pipework can run directly away from the heat pump connection.

A straight connection can also create a clean and simple external pipe layout.

Always check the heat pump connection position before choosing between straight and elbow hose options.

28mm Pipework Connection

The opposite end connects to compatible 28mm heating pipework.

Therefore, this hose pair suits many ASHP installations that use 28mm primary flow and return pipework.

Always check both connection sizes before ordering.

750mm Hose Length

Each hose measures 750mm long.

This length gives installers useful flexibility between the outdoor heat pump and fixed heating pipework.

It also allows for small differences in pipe alignment.

However, installers should avoid tight bends, twisting or unnecessary strain on the hose.

Helps Reduce Vibration Transfer

Flexible hoses help isolate vibration between the heat pump and rigid heating pipework.

As a result, less movement can travel through the pipework into the property.

This can help create a quieter installation.

However, installers should also mount the heat pump correctly and support the surrounding pipework.

Designed for Flow and Return Connections

Water-based air source heat pumps use flow and return pipework.

Therefore, two flexible hoses are commonly required at the outdoor unit.

One hose serves the heating flow. Meanwhile, the second hose connects the return circuit.

Always follow the heat pump manufacturer’s hydraulic layout.

Ideal for ASHP Replacement Work

Flexible heat pump hoses may eventually need replacement.

For example, an engineer may replace them because of:

• Hose damage
• Connection leaks
• Seal failure
• External damage
• Heat pump replacement
• Pipework alterations
• System upgrades
• Installation refurbishment

Replacing the hoses as a pair can also help maintain a consistent flow and return arrangement.

Check the Connections Before Ordering

Heat pump manufacturers use different hydraulic connections.

Therefore, always compare the existing installation before ordering replacement hoses.

This version provides:

• 750mm hose length
• 1″ female swivel connection
• 28mm pipework connection
• Two flexible hoses per pack
• Straight swivel configuration

Do not select replacement hoses from appearance alone.

External Heat Pump Pipework

ASHP flow and return pipework often runs outside the property.

Therefore, installers need to protect it against heat loss and weather.

Use suitable external-grade insulation around exposed pipework and connections.

Also, make sure the finished installation follows the heat pump manufacturer’s requirements.

Works with ASHP Isolation Valves

Flexible hoses often sit close to heat pump isolation valves.

This arrangement allows engineers to isolate the outdoor unit during maintenance.

In addition, it can make future component replacement easier.

Kudos Trading stocks several 28mm valves for suitable heat pump installations.

Works with Antifreeze Protection

Water-based monobloc heat pumps may need additional frost protection.

For example, suitable systems can use mechanical antifreeze valves on exposed flow and return pipework.

However, frost-protection requirements vary by heat pump manufacturer.

Therefore, always follow the manufacturer’s installation instructions.

Suitable Applications

The 750mm hose pair can suit compatible:

• Air source heat pumps
• Monobloc heat pumps
• ASHP flow pipework
• ASHP return pipework
• 28mm primary heating circuits
• New heat pump installations
• Heat pump replacements
• Renewable heating upgrades
• Heat pump servicing
• Low-temperature heating systems

Frequently Asked Questions

How Many Hoses Are Included?

The product comes as a pair of two hoses.

Therefore, one pack can serve both flow and return connections.

How Long Is Each Hose?

Each hose measures 750mm long.

What Connection Fits the Heat Pump?

Each hose has a 1″ female swivel connection.

Is the 1″ Connection Straight or Angled?

This version uses a straight female swivel connection.

Therefore, it differs from the separate elbow-style hose.

What Size Pipework Does It Connect To?

The opposite end connects to 28mm pipework.

Always check the system before ordering.

Why Use Flexible Hoses on a Heat Pump?

They make the final connection easier and help reduce vibration transfer.

In addition, they allow some flexibility between the outdoor unit and fixed pipework.

Are Two Hoses Normally Required?

Water-based heat pump systems normally use flow and return pipework.

Therefore, two hoses are commonly used where flexible connections form part of the installation.

Can I Use These as Replacement ASHP Hoses?

Yes, where the length and connections match the existing installation.

However, always compare the original hose specification before ordering.

Can the Hoses Connect to an Antifreeze Valve?

Yes, where the adjoining connections and hydraulic design are compatible.

Always follow the heat pump manufacturer’s frost-protection requirements.

Can the Hoses Connect to an Isolation Valve?

Yes, where the connection sizes match.

Isolation valves can make future heat pump servicing and replacement easier.
