How it works
Heat pulled from the air —
not burned from gas.
Captures warmth
The inverter draws latent heat from the surrounding air — efficiently, even on cooler days and evenings.
Transfers it to your water
A corrosion-proof titanium exchanger moves that heat into the pool as water circulates through the unit.
Holds your temperature
Variable-speed inverter technology maintains your set temperature using a fraction of the energy of gas.
One system, all season
Heats in spring.
Cools in summer.
Warm water on demand
Adds weeks to both ends of your season — it holds your set temperature from chilly spring mornings right through autumn, for a fraction of the cost of gas.
Beat the summer heat
When a heatwave turns your pool into a warm bath, reverse the cycle to gently bring the water back down to a refreshing swim temperature.
Works across a wide range of weather. The full-DC inverter keeps pulling heat from the air even when mornings dip below freezing — like every heat pump, output naturally tapers as the air gets colder.
The PoolWarmers difference
From the first warm morning
to the last light of dusk.
Add weeks to both ends of your season and swim well into the evening — with water that's always ready the moment you are.
Find your modelThe running-cost math
Up to 5× cheaper
to run than gas.
An inverter heat pump turns one unit of electricity into five-plus units of heat. For most pools that's hundreds saved every season — and the unit pays for itself in a few years.
Estimated seasonal running cost
Illustrative — based on typical heat-pump COP (~5) vs. gas efficiency (~0.85). Actual savings vary by climate, local energy rates and pool size.

Questions
Everything you
want to know.
How much does it cost to run?
An inverter heat pump is up to 5× more efficient than gas, so most owners spend a fraction of what propane or natural gas costs to heat the same pool. Your exact running cost depends on climate, local electricity rates, pool size and target temperature.
Which size do I need for my pool?
A rule of thumb: up to ~8,000 gallons → 25K BTU, up to ~13,000 → 37K BTU, up to ~20,000 → 58K BTU, up to ~24,000 → 68K BTU. Colder climates and higher target temperatures call for sizing up. Not sure? Talk to a specialist and we'll recommend the right model.
Do you ship to my country?
Yes — we ship free and fully insured across the US, Canada and the UK, with the correct voltage and refrigerant for your region.
How is it delivered and installed?
Units ship via insured freight to your door. Installation is straightforward for a qualified electrician or pool professional — the unit connects into your existing pump and filter circuit and power supply.
What does the warranty cover?
Every unit includes a 2-year whole-unit warranty, plus 5 years on the compressor. Keep your proof of purchase and register your unit after delivery to activate coverage.
Does it work in cooler weather?
Yes. DC-inverter heat pumps pull heat from the air efficiently across a wide temperature range and hold your set temperature well into the shoulder seasons. Performance naturally tapers in very cold conditions.
