Poolex Swimming Pool Heat Pumps
From compact Nano FI models to high-capacity Full Inverter systems for residential and commercial pools
Poolex is not a single heat pump with different badges. The range spans compact plug-and-play Nano models, mainstream Silverline and Jetline families, quiet premium designs, vertical-discharge units and large-capacity commercial machines. Choosing well means matching the family as well as the kW output.
Full Inverter models vary compressor and fan speed to meet demand, usually running more quietly and efficiently once the water is near the set temperature. The Silverline On/Off remains a simpler fixed-speed option where initial cost matters more than modulation.
We size Poolex equipment from heat loss and the manufacturer’s cold-condition output, not from the warm-weather maximum printed in the largest type.

A Practical Poolex Range Guide
Small and above-ground pools
Nano FI is compact, reversible and Wi-Fi enabled for pools up to the published 20 or 30 m3, depending on model.
Mainstream residential pools
Silverline FI and Jetline Selection FI cover a broad range of home pools. Jetline Selection FI is currently offered in multiple outputs and Poolex positions it as a strong price/performance family.
Space, sound and premium duties
Silverline Top and Vertigo FI provide alternative airflow arrangements. SilentJet FI, Silent Max FI, Jet Pro and Jet Max address quieter, colder-weather or larger professional duties depending on model.
Compare Output at the Same Conditions
A 15 kW figure at air 26 C cannot be compared fairly with another unit quoted at air 15 C. Read the A15/W26 or equivalent cold-condition line, electrical input and COP together.
Also check single- or three-phase supply, maximum current, flow range, water connections and airflow direction before deciding where a unit will fit.
Our Installation Checklist
- Correct heat-loss sizing and pool cover.
- Outdoor air and exhaust clearances.
- Bypass, unions and permitted water flow.
- Protected electrical supply and isolation.
- Condensate route and anti-vibration base.
- Winter drain-down or frost-protection plan.
Our advice: for a Poolex purchase, we compare two or three genuinely suitable models. A longer list is not more helpful.

Frequently Asked Questions
Which Poolex range is smallest?
Nano FI is the compact full-inverter family for small and above-ground pools.
Which Poolex range is fixed-speed?
Silverline On/Off is the conventional on/off option in the current category.
What is Jetline Selection FI known for?
Poolex positions it as a broad full-inverter range with a strong price, performance and efficiency balance.
What does Full Inverter change?
It allows compressor and fan speed to modulate instead of only switching between off and full output.
Are all Poolex models reversible?
Many are, but confirm heating/cooling modes for the exact product and variation.
Do all Poolex models use the same app?
Current Wi-Fi models use the supported Poolex platform, but older ranges can differ. Check the exact manual.
Can I choose from the maximum pool-volume badge?
Use it only as an initial guide. Location, cover, season and temperature target can require a larger unit.
Which airflow direction is best?
It depends on clearance and neighbour position. Compare horizontal, top or vertical discharge requirements for the chosen family.
Do larger models need three-phase power?
Some do. Confirm voltage, phase, maximum current and starting arrangement before ordering.
Is salt-water treatment compatible?
Many Poolex units use a titanium exchanger, but stay within the exact model water-chemistry limits.
Why might a discontinued model remain visible?
We retain useful product information and point customers to the current equivalent where appropriate.
Can you compare Poolex with Remora or ProTeam?
Yes. We can compare cold-condition output, noise, controls, warranty, electrical demand and cost for the same pool duty.
Why is a pool cover so important?
Most heat escapes from the water surface. A suitable cover can reduce heat loss dramatically and may change the heat-pump size and running cost.
Does the headline kW stay the same in cold weather?
No. Heat output and COP change with air temperature, water temperature and humidity. Compare the cold-condition performance for your season.
What does COP mean?
Coefficient of performance compares heat delivered with electrical input at stated test conditions. It is not a fixed year-round efficiency figure.
Why is a bypass useful?
A correctly set bypass helps keep flow through the heat exchanger within the permitted range and makes isolation and servicing easier.
Is water beneath the outdoor unit a leak?
Often it is normal condensate from the evaporator, especially in damp weather. Check that it is clear water and that the condensate drain is unobstructed.
Can the unit be enclosed in a shed?
Normally no. It needs the manufacturer clearances and unrestricted outdoor airflow; recirculating cold exhaust air reduces output and efficiency.
Who should install the electrical supply?
A qualified electrician should provide the correct protected circuit, isolation and cable sizing. Plug-fitted models still need a suitable outdoor supply.
How do I prevent frost damage?
Follow the exact winterising instructions. If the circulation is stopped, drain all trapped water from the heat exchanger and pipework.
Can you help size a heat pump?
Yes. Send water volume, surface area, target temperature, months of use, location, cover type, filtration flow and electrical supply.
Should chemical dosing enter before the heater?
Follow the installation manual; dosing equipment is normally placed downstream so concentrated chemical cannot enter the heat exchanger.
Why does flow matter?
Too little flow can cause faults or poor heat transfer; too much can exceed the unit limits. Use the specified range for the exact model.
How long will initial heating take?
It depends on water volume, starting and target temperatures, weather, cover and the unit’s output at those conditions. Maintaining temperature is easier than the first warm-up.
