750mm ASHP Hose Pair 1″ x 28mm
Supplied as a Pair
Each pack contains two 750mm hoses.
Therefore, one pair can serve both the heat pump flow and return connections.
This also helps installers keep both connections consistent during installation.
1″ Female Swivel Elbow Connection
The heat pump end features a 1″ female swivel elbow.
The swivel connection makes final assembly easier. In addition, the elbow helps where installation space around the heat pump is limited.
The angled connection can also create a neater pipe route than a straight fitting.
28mm Pipework Connection
The opposite end connects to compatible 28mm heating pipework.
Therefore, the hose pair suits many domestic air source heat pump installations using 28mm primary pipework.
Always confirm the heat pump connection and pipe size before ordering.
750mm Hose Length
Each hose measures 750mm long.
This provides useful flexibility between the outdoor heat pump and fixed heating pipework.
The additional length can also reduce stress caused by small alignment differences.
However, avoid unnecessary bends or strain during installation.
Helps Reduce Vibration Transfer
Flexible hoses help separate heat pump movement from rigid copper pipework.
As a result, they can reduce vibration travelling through the heating system.
This can help create a quieter installation.
However, correct heat pump mounting and pipe support remain important.
Ideal for Flow and Return Connections
An air source heat pump needs both a flow and return connection.
Therefore, supplying the hoses as a matched pair makes installation straightforward.
One hose connects the flow circuit. Meanwhile, the second hose connects the return.
Always follow the heat pump manufacturer’s hydraulic layout.
Useful for Heat Pump Replacement Work
Flexible hoses can eventually need replacement during the life of an ASHP system.
Possible reasons include:
- Hose damage
- Connection leaks
- Seal failure
- Heat pump replacement
- Pipework alterations
- System upgrades
- Weather damage
- Installation refurbishment
A replacement pair helps restore both flow and return connections at the same time.
Check Connections Before Ordering
Heat pump manufacturers use several connection sizes.
Therefore, always check the existing installation before ordering replacement hoses.
This pair uses:
- 1″ female swivel elbow heat pump connections
- 28mm pipework connections
- 750mm hose length
- Two hoses per pack
Do not select replacement hoses from appearance alone.
External Heat Pump Pipework
External heat pump pipework needs suitable protection against heat loss and weather.
Therefore, ensure the finished hose and pipework installation has suitable external-grade insulation.
Pay particular attention to joints and connection areas.
The heat pump manufacturer’s installation instructions should always take priority.
Works Alongside ASHP Isolation Valves
Heat pump installers commonly use flexible hoses alongside isolation and frost-protection valves.
For example, the hose may connect between the heat pump and an isolation valve.
This arrangement can make future maintenance easier.
It also allows the engineer to isolate the outdoor unit when required.

Frequently Asked Questions
How Many Heat Pump Hoses Are Included?
The product comes as a pair of two hoses.
Therefore, one pack can connect both flow and return pipework.
How Long Are the Hoses?
Each hose measures 750mm.
What Connection Fits the Heat Pump?
The heat pump end uses a 1″ female swivel elbow connection.
What Size Pipework Do They Connect To?
The opposite end connects to 28mm pipework.
Always confirm the installation before ordering.
Why Use Flexible Hoses on an Air Source Heat Pump?
Flexible hoses help reduce vibration transfer between the heat pump and fixed pipework.
They also make final alignment easier during installation.
Why Choose an Elbow Connection?
The elbow helps route the hose where space is restricted.
Therefore, it can produce a neater connection close to the outdoor unit.
Are Two Hoses Needed for a Heat Pump?
Most water-based ASHP systems have a flow and return circuit.
Therefore, two hoses are normally required where flexible connections form part of the installation.
Can I Use These as Replacement Heat Pump Hoses?
Yes, where the existing connections and hose length match.
Always compare the old hose and heat pump specification before ordering.
Can They Connect to an Antifreeze Valve?
They can connect within a compatible ASHP hydraulic arrangement where the adjoining connections match.
Always follow the heat pump manufacturer’s recommended pipework layout.
