Heat Pumps in Cyprus: The Buyer’s and Rental Guide
We get the same call every summer: a warehouse, showroom or office in Cyprus that’s uncomfortably hot for half the year with no real plan for winter heating. This guide compares our RTH45 and RTH65 rooftop heat pumps, when we’d point you toward one over a split air conditioner, and whether renting or buying makes more sense for your building.
Heat pump or air conditioner: what’s the real difference
A heat pump does the same job as a split air conditioner for a Cyprus building, and adds heating, because it can reverse its own refrigerant cycle. In cooling mode it removes heat from indoors and rejects it outside, exactly like our 24000 BTU split air conditioner. In heating mode it runs the same cycle in reverse, pulling heat from outside air and moving it in. A cooling-only air conditioner can’t do that second half.
If your space only ever needs cooling, our guide to air coolers in Cyprus covers the split air conditioner in more depth. If you need heating as well, or you’re fitting out a larger commercial space from scratch, the rest of this guide is for you.
When you compare heat pumps by their COP, EER, SEER or SCOP figures, those numbers aren’t marketing claims, they’re measured under EN 14511 and EN 14825, the EU standards that define how manufacturers test and rate heating and cooling performance. It’s worth checking a unit was rated under these standards before comparing it against another on efficiency alone.
What we stock: RTH45 and RTH65 rooftop heat pumps
We carry two rooftop heat pump models built for different building sizes: the RTH45 for larger commercial spaces, and the higher-capacity RTH65 for buildings that need more from a single system. Both sit within our wider cooling and heating equipment in Cyprus range, alongside the 24000 BTU split air conditioner, and are packaged units, meaning the compressors, coils and fans all sit in one roof-mounted cabinet rather than split between indoor and outdoor components.
| Unit | Best suited to | How it works | Note |
|---|---|---|---|
| RTH45 rooftop heat pump | Warehouses, retail units and industrial buildings | Packaged rooftop unit, roughly 44-53 kW cooling and 40-46 kW heating, 400V 3-phase, dual compressor | Confirmed specifications; full detail in our dedicated RTH45 guide |
| RTH65 rooftop heat pump | Larger buildings or higher-occupancy spaces than the RTH45 covers | Same packaged rooftop principle as the RTH45, scaled up for greater capacity | Talk to us for a capacity match to your building; we’ll confirm the right model on-site |
Sizing and installing a rooftop heat pump
Sizing a rooftop heat pump for a Cyprus building starts with floor area, occupancy and ceiling height together, not floor area alone, and we always check roof access and structural load before recommending a model between the RTH45 and RTH65. Both are packaged systems weighing close to a tonne, so the roof needs to take that weight, and there has to be a sensible route for ductwork into the building.
| Building type | Typical scale | Recommended unit | Key consideration |
|---|---|---|---|
| Warehouse or retail unit | Standard commercial footprint | RTH45 rooftop heat pump | Roof access and structural load need checking before installation |
| Larger commercial or industrial building | Higher occupancy or larger footprint than the RTH45 covers | RTH65 rooftop heat pump | Same installation principles as the RTH45, scaled for the larger unit |
| Single room or small office (cooling only) | Up to roughly 30-40 m² | 24000 BTU split air conditioner | See our air coolers guide, no rooftop installation needed |
We’ve written a full breakdown of RTH45 capacity, airflow and installation detail in our dedicated RTH45 specification guide, if you want the technical depth before we visit site.
Installation isn’t just a Psilos preference, it’s a legal requirement. Under Cyprus’s Energy Efficiency of Buildings Law, anyone installing cooling, heating or ventilation systems must hold a registration certificate issued by the Ministry of Energy, Commerce and Industry, which is exactly the checkpoint we work to on every heat pump install.
Rent or buy: which makes sense for your building
Rent if the need is short-term, such as a single project or season. Buy if you’re heating and cooling the same building year after year, since ownership becomes the cheaper option once you’re past a handful of seasons of rental costs.
Heat pump rental in Cyprus through Psilos Group covers both the RTH45 and RTH65, alongside outright purchase.
Our consultation and installation services team can talk through sizing and the rent-or-buy decision before you commit to anything, with no pricing published here since every building is different.
When to upgrade from a split air conditioner
If you need heating as well as cooling, or you’re fitting out a larger commercial space from scratch, a rooftop heat pump is the better long-term fit, because it handles both jobs through one system instead of leaving winter heating unaddressed. The 24000 BTU split air conditioner in our range is cooling-only, which is fine for a single room, but it isn’t the right tool once a building needs year-round climate control.
There’s also a compliance angle worth knowing about if you’re renovating: Cyprus, like the rest of the EU, sets minimum energy performance requirements for buildings undergoing major renovation, and swapping a cooling-only unit for an efficient heat pump is a straightforward way to help a building meet its energy performance certificate obligations.
What we’re seeing on the ground
Enquiries for rooftop heat pumps tend to pick up sharply in the run-up to summer, and again in early autumn once buildings that only planned for cooling start thinking about winter. The most common sizing mistake we see on site visits is a building owner working from floor area alone, without factoring in ceiling height or how many people are actually working in the space day to day, both of which change the real heating and cooling load. Roof access is the other thing that catches people out: a rooftop unit only works if there’s a safe, weight-rated way to get it up there and route ductwork back down into the building, which is exactly why we check this on-site before recommending a model rather than over the phone.

Frequently asked questions
What is the difference between a heat pump and an air conditioner?
A heat pump can reverse its refrigerant cycle to provide heating as well as cooling, while a standard air conditioner only cools. Our RTH45 and RTH65 rooftop units are heat pumps; our 24000 BTU split unit is cooling-only.
What size heat pump does a commercial building in Cyprus need?
It depends on floor area, occupancy and ceiling height together, not floor area alone. We size on-site rather than over the phone, since roof access and structural load also affect which model fits.
Is it cheaper to rent or buy a heat pump in Cyprus?
Rent for a short-term or seasonal need, buy for year-round use. We rent and sell both the RTH45 and RTH65, and we can advise based on how long you’ll actually be using the space.
What’s involved in installing a rooftop heat pump?
Both models are packaged rooftop units weighing close to a tonne, so we check roof access, structural load and ductwork routing on-site before confirming a model.
Do heat pumps work well through a Cyprus winter?
Yes. The same system that cools through summer reverses to provide heating through the milder Cyprus winter, so one unit covers both seasons.
What’s the difference between the RTH45 and RTH65?
Both are packaged rooftop heat pumps built on the same principle; the RTH65 is the higher-capacity model for buildings that need more than the RTH45 provides. We’ll confirm the right fit for your building on-site.
How much does it cost to run a commercial heat pump?
Running costs scale with the unit’s capacity and how hard it’s working, so we don’t publish a single figure here. Get in touch for a consultation based on your building.
Can a heat pump replace a split air conditioner?
Yes, and it adds heating capability the split air conditioner doesn’t have. For a single small room that only ever needs cooling, the split unit is still the simpler choice; see our air coolers guide for that comparison.
Do heat pump installers in Cyprus need any kind of certification?
Yes. Under Cyprus’s Energy Efficiency of Buildings Law, anyone installing cooling, heating or ventilation equipment must hold a registration certificate from the Ministry of Energy, Commerce and Industry, which we work to on every installation.
