Presentation
The Wellea Monobloc DF HT (Wellea M DF HT) monobloc heat pump uses the natural refrigerant R290 (GWP 0.02) and delivers an all-in-one solution for domestic hot water production, space heating and cooling. Designed for high capacities, it features top energy ratings and integrated protection and efficiency technologies to lower environmental impact while optimizing energy consumption.

Key features

• Natural refrigerant R290 (GWP = 0.02) with low environmental impact
• High energy rating (A+++ where applicable)
• Green Fin treatment protecting heat exchangers against corrosion
• Maintains heating capacity down to -10°C without electrical backup
• Outdoor operating range: -25°C to +46°C
• Refined design and low-noise operation for acoustic comfort
• Compatible with all emitter types: existing radiators or underfloor heating (suitable for renovation)
• Pack supplied: outdoor unit and remote control (monobloc solution)

Use and benefits
Designed for residential and small collective applications, the Wellea M DF HT can replace an existing boiler to improve thermal comfort while reducing energy consumption. Up to 80% of the required thermal energy can be extracted from ambient air and transferred to heat water. It can also be used to cool the building if required.
