What best can mean here
Best is a fit for a volume and a connection. The CG-26664 is 4.4 from 1,055 reviews and the Briidea is also 4.4, from 66. One is an inline hose unit. The other is a drop-in. The top pick is the Intex 26670, the only listing that prints 12 g/h. The best value is the CG-26664 at about £118.56, with grams per hour missing from that page. The sizing rule is the salt chlorinator buying guide.
The small inline with the large review file
The Intex CG-26664 is about £118.56, a 230 V inline system. UK reviews describe it as easier than granules on a small above-ground pool. Hose detail is on salt chlorinator above ground pool. Grams per hour are not in the bullets. A QS400 manual states 4 g/h and 32 mm fittings. One UK review says it did not cover a 17,000 litre pool. Skip it in that larger band.
The listing that prints 12 g/h
The Intex 26670 is about £301.32, 4.3 from 1,090 reviews. The bullets state 12 g/h, salt at 2.5–3.5 g/L and a filter of at least 2,650 litres per hour. Poolpro's 3-pin stock of the same model number is not ASIN B07C9JL6RZ. A verified UK review says this ASIN came with a Euro plug. Do not cut that plug off. Leave it for a small storable pool, or when the parcel must arrive with a BS 1363 plug.
App cells and the ozone-titled unit
The Bonvoisin is about £286.92, up to 22,400 gallons, with no grams per hour. The YUCHENGTECH is about £329.89, up to 85 m³, with no star line. Skip both when you need a printed rate. The Intex 26666 is about £341.12. Output, volume and hose size are not stated. An 11 g/h figure belongs to model 26665 on a US page, not to 26666. Skip it as a first system.
Drop-ins for a hot tub
A hot tub is not a small pool you point the 26670 at. The Westaho is about £161.41, stated for 200–2,200 gallons. The Briidea is about £169.89, stated up to 2,000 gallons. The tub page is hot tub salt chlorinator. Choose a drop-in only inside the stated gallons, and only if the tub maker accepts salt.
Common questions
Which of these is the one for a small above-ground pool?
The Intex CG-26664 at about £118.56 is the best value for that job, with 4.4 from 1,055 reviews. UK reviews describe it as easier than granules. Grams per hour are not on the listing. A QS400 manual states 4 g/h and 32 mm fittings. One UK review says it did not cover a 17,000 litre pool. If your pool is in that band, this is the unit to skip.
When is the 12 g/h Intex the clearer listing?
When you want the rate, the salt window and the filter flow on the same amazon.co.uk page. The Intex 26670 states 12 g/h, 2.5–3.5 g/L and at least 2,650 litres per hour, at about £301.32, with 4.3 from 1,090 reviews. It is the top pick here for that reason. A UK review reports a Euro plug, so a clearer listing is not a UK plug included.
Are the Wi-Fi cells a better buy because the gallon number is higher?
No. The Bonvoisin's 22,400 gallons and the YUCHENGTECH's 18,700 gallons, also written as 85 m³, are ceilings. Neither page states grams per hour. Steps from 20% to 100% do not say how many grams 100% is. The Bonvoisin is 3.9 from 19 reviews, and the saved texts are not from the UK. The YUCHENGTECH has no star line.
Which unit is for a hot tub?
The Westaho EL-024 and the Briidea BR-159. They are drop-ins. The Westaho states 200–2,200 gallons at about £161.41 and 4.0 from 6 reviews. The Briidea states up to 2,000 gallons at about £169.89 and 4.4 from 66 reviews. Saved texts for both are from outside the UK. An Intex pool cell, including the 12 g/h unit, is the wrong install for a few hundred litres.
Does the highest star rating mean the largest pool?
No. The CG-26664 and the Briidea are both 4.4, and they are different jobs. The 26670 is 4.3 from 1,090 reviews and is the listing with 12 g/h. Stars count buyers. They do not measure volume.
What should I skip if reviews mention a Euro plug?
Skip treating the 26670 and the 26666 as ready for a UK socket. A verified UK review of the 26670 describes a Euro plug. A 2016 UK review of the 26666 says the plug is not UK compatible. A shop's 3-pin stock of the same model is a different supply. The QS400 manual says not to use converter plugs. An electrician is the next step.
Is there a best unit for every pool?
No. A small above-ground pool points at the CG-26664 if you accept a manual for the 4 g/h figure. A larger pool whose filter meets 2,650 litres per hour points at the 26670 if you will deal with the plug. A 48 mm PVC return points at the Bonvoisin only with the missing grams-per-hour figure in view. A hot tub points at a drop-in, or at neither if the warranty and the reviews do not satisfy you.
