Heat Pumps in Egypt: Pool, Hot Water & Space Heating
A heat pump does not make heat — it moves it. That single difference is why a heat pump can deliver three to five times more heat energy than the electricity it consumes, and why it is now the most efficient way to heat a pool, a home's hot water, or the home itself. We design, supply and install heat pump systems across Egypt for all three applications.
How a heat pump actually works
A heat pump runs a refrigerant around a sealed circuit. The refrigerant evaporates at low temperature and pressure, absorbing warmth from the outside air. A compressor then raises its pressure and temperature, and it gives that heat up to your water before condensing and starting again. It is the same cycle a refrigerator uses, run in the useful direction.
Because the machine is transporting existing heat rather than generating it, its output is not limited by the electricity it draws. A direct electric heater converts one kilowatt of electricity into exactly one kilowatt of heat and can never do better. A heat pump routinely returns three to five kilowatts of heat for each kilowatt it consumes. That ratio is the Coefficient of Performance, or COP, and it is the whole economic argument.
COP: what it means and what changes it
COP is not a fixed badge on a product — it is a measurement taken under stated conditions, and it moves with those conditions. Two things drive it.
The first is the outside air temperature. The warmer the air, the more energy there is to harvest and the higher the COP. This is why heat pumps perform better in Egypt than in northern Europe, and why a unit sized on summer conditions will disappoint in January.
The second, and the one most often ignored, is the temperature you ask the water to reach. The bigger the gap between outside air and target water temperature, the harder the compressor works and the lower the COP. This is why a heat pump paired with underfloor heating at 35-45 degrees is dramatically more efficient than the same heat pump forced to feed radiators at 65 degrees. Whenever you see a quoted COP, ask which conditions it was measured at.
Three applications, three different machines
"Heat pump" is a category, not a product. The unit that heats a pool is not the unit that heats your showers. We work across all three:
Pool heating: A pool heat pump holds a large volume of water at a modest temperature against constant evaporation loss. It is the most efficient way to extend the swimming season, and because pool water only needs 28-30 degrees, the COP stays high. Sizing depends on surface area, wind exposure and the season you want to swim in — not volume alone.
View DetailsDomestic hot water: A heat pump water heater pulls heat from the surrounding air into a storage cylinder. It suits households with steady, significant hot water demand, where the saving against an electric element compounds every day. Available as all-in-one units with the tank integrated, or split systems where the heat pump sits apart from the cylinder.
View DetailsSpace heating: An air-to-water heat pump feeds your central heating circuit. It is the natural partner for underfloor heating because both work best at low water temperature. With radiators it still works, but they must be sized for lower flow temperatures — which usually means larger radiators than a boiler system would need.
View DetailsWhy heat pumps make particular sense in Egypt
Egypt's climate is close to ideal for air source heat pumps. The efficiency of any air source machine falls as the outside air gets colder, which is the main constraint in northern climates — and it is largely absent here. Egyptian winters are mild enough that a well-specified heat pump holds a high COP through the season, and Egyptian summers give exceptional performance for pool and hot water duty.
There is a second, less obvious argument. Egyptian homes often need three separate things heated: the pool, the domestic hot water, and the house. A heat pump can serve all three, and a plant that works year-round is far easier to justify than one idle for eight months.
The honest counterweight is capital cost. A heat pump costs more upfront than a gas boiler or an electric heater. It repays that difference through running cost, so the calculation depends on how much heat you actually use. High, steady consumption pays back fast. Occasional use pays back slowly.
Types of heat pump
- Air-to-water — extracts heat from outside air and delivers it to water, for pools, hot water cylinders, underfloor heating or radiators. The most common type in Egyptian residential work.
- Monobloc — the entire refrigerant circuit sits in one outdoor unit, with only water pipes running into the building. Simpler installation and no refrigerant work on site.
- Split — the system is divided between an outdoor unit and an indoor module, connected by refrigerant lines. More installation flexibility, but the refrigerant circuit is made on site and demands competent work.
- All-in-one water heater — heat pump and storage cylinder in a single cabinet, the simplest option for domestic hot water where there is space and air flow.
- Split water heater — the heat pump unit is separate from the cylinder, useful where the cylinder must go somewhere without good air movement.
- Hybrid — a heat pump paired with a gas boiler, with controls switching between them. Rare in Egypt but useful where peak demand occasionally exceeds what the heat pump alone can deliver.
- Reversible — units that provide cooling as well as heating, so a single machine covers both seasons.
Heat pump, gas or electric?
Direct electric is the simplest to install and the most expensive to run, because every kilowatt of electricity yields exactly one kilowatt of heat. It makes sense for a small isolated load, and rarely for anything larger.
Gas gives high output, fast recovery and a low initial cost where a mains connection exists. Running cost tracks the gas price. It needs a flue, ventilation and competent installation, and it remains the pragmatic answer for large peak loads and intermittent use.
A heat pump has the highest capital cost and by far the lowest running cost, because of the multiplication effect. It heats more slowly than a gas burner, so storage capacity becomes part of the design rather than an afterthought.
The deciding question is not which technology is best in the abstract — it is how much heat you use and how steadily. A villa with a pool, a family's daily hot water and winter heating is exactly the profile where a heat pump wins. A rarely used guest apartment is not.
Sizing: the step that decides everything
Every failed heat pump installation we are called to inspect has the same root cause, and it is almost never the equipment. It is that the system was sized on a rule of thumb rather than a calculation, and usually on summer conditions rather than winter ones.
An undersized heat pump does not simply heat more slowly. On the coldest days it runs continuously, replacing losses with nothing left over, and never reaches target temperature at all. An oversized one wastes capital and can short-cycle, which shortens compressor life.
For space heating the calculation must be room by room — glazing, external walls, orientation, ceiling height and insulation, not floor area. For pools it is driven by surface area, wind exposure, target temperature and season. For hot water it is fixtures and simultaneity, not bedroom count. All three are different calculations, and we run the appropriate one on every project.
What would you like to heat?Refrigerants: the specification nobody asks about
The refrigerant determines a heat pump's environmental footprint, part of its safety profile, and how practical it will be to service in ten years.
Global Warming Potential measures a gas's warming effect if released, against carbon dioxide at 1. Older refrigerants score in the thousands. R290 — propane — is a natural refrigerant with a near-negligible GWP, which is why modern designs increasingly use it. The trade-off is honest: hydrocarbons are flammable, so R290 systems use low charge volumes, sealed circuits and specific installation requirements, and servicing competence matters more.
R134a and R410A are established, well-understood alternatives with technicians everywhere who know them, but higher GWP. Regulation in many markets is progressively restricting high-GWP options, so a refrigerant that is cheap and available today may be difficult to source over the equipment's life. Ask which refrigerant a unit uses and what servicing it in Egypt will involve.
What installation actually requires
- Air flow — a heat pump needs a generous, unobstructed volume of air across its evaporator. Boxing a unit into a tight shaft or a sealed enclosure is the most common installation error and it silently destroys efficiency.
- Location and noise — units produce noise. Placement relative to bedrooms and neighbours should be considered at design stage, not discovered afterwards.
- Electrical supply — capacity, phase and protection must suit the unit. Larger machines are frequently three-phase.
- Condensate drainage — the evaporator produces condensate that must drain away properly.
- Water quality — hard water scales heat exchangers. Materials and treatment matter as much here as in any water heater.
- Winter design conditions — capacity must be selected for the coldest days, not average or summer conditions.
The brands we work with
We are the authorized exclusive dealer for GRAT heat pumps in Egypt, covering residential full-inverter units through to commercial machines for club, hotel and Olympic-scale pools. We also supply Heat Shift, our own OEM line of all-in-one heat pump water heaters, alongside Richmond, A.O. Smith, Heat Master and others across the wider range.
Brand depth matters here for a specific reason: heat pump applications differ so much that no single manufacturer is the right answer for a pool, a hot water cylinder and a space heating circuit at once. Being able to specify across brands means the recommendation follows the calculation rather than the catalogue.

Frequently asked questions
How much can a heat pump save?
Against direct electric heating the saving is substantial, because a heat pump returns several times the energy it consumes while an element returns exactly one. Against gas it depends on relative energy prices and how much heat you use. The honest answer for any specific property comes from a calculation, not a percentage in a brochure.
Do heat pumps work in Egyptian winters?
Yes, and better than in most markets where they are standard. Efficiency does fall as air temperature drops, which is exactly why capacity must be selected for winter design conditions rather than annual averages.
Can a heat pump replace my gas boiler?
Often yes, but not as a like-for-like swap. Heat pumps work at lower flow temperatures, so the emitters usually need revisiting — underfloor heating is ideal, and radiators must be sized for cooler water, which generally means larger ones.
How noisy are they?
There is a fan and a compressor, so there is noise. Manufacturers publish sound levels and quieter units exist. What matters most is placement relative to bedrooms and neighbours, decided at design stage.
How long do they last?
A well-installed, properly maintained unit should give many years of service. Air flow, water quality and annual servicing are the factors that most affect it.
Can one heat pump do the pool, hot water and heating?
Sometimes, with correct design and control priorities. But the three duties have very different temperature and load profiles, so combining them is an engineering decision — not something to assume.
Is a heat pump worth it for a rarely used property?
Usually not. The premium is repaid through running cost, so it needs consistent use. Occasional demand favours a cheaper capital option.
