GARDENA 2400 ComfortAutomatic Water-Butt Pump: Solo or Set?
Some links in my articles are affiliate links. I may earn a commission when you buy through them.
Choose the GARDENA 2400 ComfortAutomatic Solo, 14605-55, if you already have a compatible PBA 18V POWER FOR ALL battery and its suitable charger available for watering. If you need both, compare the 14605-20 Ready-to-Use Set against the total cost of buying the missing equipment separately.
The set adds battery and charger equipment; it is not a more powerful version of the 14605 pump. Before ordering a set for use in the UK, confirm the supplied charger’s plug and exact contents with the seller. The international “Ready-to-Use” name alone does not establish that detail.
If your existing battery and charger match the requirements, check the 14605-55 Solo listing on Amazon UK. It is the without-battery option; keep that selection when comparing offers.
What each 14605 package includes
| Package | Equipment to expect |
|---|---|
| 14605-55 Solo | Pump and battery box, telescopic tube with anti-siphon valve and tap connection, barrel hook and wall mounting plate. Battery and charger are separate. |
| 14605-20 Ready-to-Use Set | The pump arrangement with battery and charger. GARDENA’s international listing names a PBA 18V/45 battery and AL 18V-20 charger. |
The September 2026 operating manual confirms that article 14605-20 includes a battery and charger. The two Amazon UK variants checked for this guide identify 14605-20 as “with battery” and 14605-55 as “without battery”. Read the actual offer’s contents as well as its photograph: shared listing pages can display several configurations.
Neither package description makes your garden hose, spray gun or irrigation layout part of the purchase. List those separately if you do not already have suitable fittings. Check the barrel opening and the route for the telescopic outlet before paying for accessories.
Choose around equipment you already own
A compatible battery and charger, with time to share them: Solo avoids buying another power package. Check the battery’s full label first. An 18V marking or a Bosch badge is not sufficient; Bosch Professional and POWER FOR ALL are different systems. Our pump battery and charger guide gives the exact types and recharge figures.
No compatible battery or charger: the set gives you one package to compare against a pump plus a separately sourced battery and UK-suitable charger. If the set’s supplied plug remains unclear, obtain the seller’s confirmation or choose a clearly specified alternative package.
A battery that is already busy in another tool: allow for when you actually water. Sharing one pack works when the jobs happen at different times and there is time to recharge. If the pump must remain installed for scheduled watering while you use the other tool, a dedicated compatible pack may be more convenient. Compare that purchase with the set rather than treating the battery you own as permanently available.
Compare the complete usable cost
For the Solo route, add the pump price, any battery and charger you still need, and delivery. For the set, add its price, delivery and anything the supplied package does not cover. Include only equipment you genuinely need: an existing suitable charger need not be bought again.
Solo route: pump + missing compatible battery + missing suitable charger + delivery.
Set route: set + any still-missing equipment + delivery.
Use prices with VAT on the same basis. A business account may show an excluding-VAT figure prominently, which can make two otherwise comparable offers look further apart than they are.
No fixed saving is quoted here because the combination of equipment you own and current offers decides it.
Make sure cordless watering suits the job
The 14605’s demand-controlled automatic mode suits moving between pots with a compatible spray nozzle: opening the outlet starts pumping and closing it stops the pump. The battery box stays outside the tank, protected from water. The pump manual also provides timer and scheduler modes; the pump is not intended for continuous operation.
For a small number of nearby pots, filling a can from the butt tap may still be sufficient. For longer watering sessions, consider both the battery’s recharge routine and the stored water available. A mains-powered pump may suit an installation with an appropriate safe supply, but choose its controls and pressure for the job. Our water-butt pump buying guide compares pressure, hose reach and usable storage.
A battery bundle does not establish compatibility with every tap timer or drip layout. If you need an automatic watering installation, use the exact equipment instructions and our pump-control comparison before buying additional controls.
Check the UK supply before ordering
Match the model number, selected battery option and seller’s included-items description. For the set, ask which charger and plug are supplied for UK use; do not infer the plug from the marketplace domain. For Solo, confirm your existing battery and charger against the current manual. If either is incompatible, recalculate the purchase with the required equipment included.
After delivery, charge the battery as instructed and commission the complete arrangement while you are present. Check its start, normal watering and stop with the final hose and outlet. A successful short run does not establish that the tank and battery will cover every future scheduled cycle.
