Leinster Heat Pumps** Retrofit in Dunlavin

A successful heating retrofit delivered by Leinster Heat Pumps in Dunlavin, upgrading an existing home to high-efficiency, low-carbon comfort.

The Solution

The installer replaced the legacy system with a Viessmann Vitocal 151‑A R290 monobloc heat pump, paired with KERS+ for enhanced efficiency. To improve indoor air quality and reduce ventilation heat loss, single‑room heat recovery vents were installed throughout the property using KERS+ Single Room Heat Recovery Vents.

For maximum energy reuse, the home also integrated KERS+ heat recovery vents, capturing extract air heat and returning tempered fresh air to each space independently.

Key Benefits

• Ultra-low carbon heating — natural refrigerant (R290) with minimal GWP

• Fast retrofit installation — all-in-one cylinder-integrated heat pump design

• Improved air quality — balanced ventilation with room-by-room heat recovery

• Optimised energy reuse — reduced ventilation heat loss without sacrificing comfort

• Installer-friendly controls — simple commissioning and end-user operation

Project Outcome

The retrofit achieved a significant reduction in energy demand and carbon emissions while delivering:

• Consistent, responsive heating

• Noticeably fresher, better-circulated indoor air

• A future-proof system ready for long-term efficiency and sustainability
