Condensing boiler & heat pump installation in Uccle
Upgrade your old inefficient boiler to a system engineered specifically for your Uccle property: a high-modulation condensing gas boiler (1:10) or a whisper-quiet air-to-water heat pump.
- Full thermal heat-loss survey & accurate output sizing
- Hydrodynamic power flushing of radiators & underfloor heating
- Cerga gas compliance & RESCERT commissioning for regional grants
Condensing gas boiler, heat pump or hybrid system?
Every building in Uccle has unique thermal characteristics — from 1930s townhouses near Globe to detached villas in Prince d’Orange or apartments on Avenue Messidor. We never guess capacity: we measure true heat loss and emitter flow temperatures.
Where existing radiators perform well at low flow temperatures (45–55°C), an air-to-water heat pump (Daikin Altherma, Vaillant aroTHERM plus) delivers maximum efficiency and unlocks the highest Renolution grants. For compact spaces or high-temperature circuits, condensing boilers or hybrids remain a rock-solid choice.

Acoustic & urban planning expertise in Brussels
In dense Brussels neighbourhoods, outdoor heat pump positioning must respect strict acoustic boundaries toward neighbours. We specify ultra-quiet units (< 35 dB(A) at 5 m) mounted on anti-vibration plinths.
