High-temperature air-to-water heat pump WAO
High-temperature air-to-water heat pump WAO
An all-in-one solution for heating, cooling and domestic hot water production
The WAO is a reversible high-temperature air-to-water heat pump designed to meet all the thermal needs of a home: heating in winter, cooling in summer, and domestic hot water production.
Particularly suited for energy renovation projects, it can in many cases replace a gas or oil boiler while retaining existing radiators.
Thanks to its ability to deliver leaving water temperatures up to 70°C and operate down to -25°C, the WAO provides reliable thermal comfort, even in regions with harsh winters.
Why choose the WAO heat pump for your project?
Up to 70°C supply temperature | Operating down to -25°C | R290 | Remote control & monitoring
The WAO combines high performance, ease of use, and simple integration into existing homes.
It stands out in particular for:
- Supply temperature up to 70°C
- Operating temperature down to -25°C
- Natural refrigerant R290
- Quiet operation and intelligent control
- Remote control via the Warmeo app
- Monobloc design for easier installation
- 7-year warranty
A low-impact R290 heat pump
The WAO uses R290, a natural refrigerant with a very low environmental impact, fully aligned with current and future industry regulations.
R290 stands out in particular for:
- A very low global warming potential (GWP)
- Compliance with evolving regulations
- Excellent energy performance, including in winter
A heat pump designed for operation down to -25°C
The WAO heat pump operates down to -25°C outdoor temperature to ensure stable thermal comfort even under demanding winter conditions.
It includes several reliability-enhancing features:

FAQ: WAO Residential Heat Pump
Yes. The WAO is designed to replace existing gas or oil boilers in many renovation projects. Thanks to its supply temperature of up to 70°C, it can operate with existing radiators without requiring a full replacement of the heating system.
In most cases, yes.
The WAO can produce sufficiently high water temperatures to operate with existing radiators, which are generally already sized for high-temperature heating systems such as older gas or oil boilers.
Yes. The WAO is an all-in-one solution: it provides heating, cooling, and domestic hot water production, depending on the system configuration.
Yes, the WAO is reversible. It can provide cooling in summer through a suitable system (such as a cooling floor or compatible emitters).
R290 is a natural refrigerant with a very low environmental impact, offering:
- a very low Global Warming Potential (GWP)
- high energy efficiency
- compliance with current and future industry regulations
No. The WAO is equipped with Inverter technology and a variable-speed fan, allowing it to adapt its operation and significantly reduce noise levels.
The WAO can be controlled locally via its RLB100 interface or remotely via the Warmeo app, allowing adjustment of operating modes, temperatures, and schedules.
The WAO stands out for its ability to deliver high temperatures (up to 70°C), operate down to -25°C, and use R290 refrigerant. It is therefore particularly suited to major renovation projects and boiler replacement.
Yes. The WAO is designed to operate down to -25°C outdoor temperature, ensuring stable heating comfort even in extreme weather conditions.
Yes, the WAO heat pump may be eligible for certain energy renovation incentives (such as MaPrimeRénov’, CEE schemes, or other available programs), provided that the project and installation meet the criteria set by government authorities and relevant organizations.
Available incentives depend mainly on:
- your household income level
- your home’s characteristics
- the type of replacement (e.g. replacing an oil or gas boiler)
- installation carried out by a qualified RGE professional
We recommend having your project assessed in advance to determine exactly which incentives you may be eligible for.
