What is a Heat Pump?

A heat pump is a highly efficient heating system that captures natural heat from the air outside and uses it to warm your home and water.It doesn’t burn fuel like a boiler — it moves heat, making it cleaner, more efficient, and cheaper to run. Even in cold Irish winters, it delivers steady, reliable comfort.
The result? Lower running costs, steady comfort, and a cleaner way to heat your home.

How the Heat Pump Installation Works

Installing a heat pump is usually simpler than homeowners expect.

A compact outdoor unit is fitted beside or behind your home
Your existing boiler is removed
A high-efficiency hot water cylinder is installed
Radiators are upgraded if needed
The system is connected, tested, and optimised

Most installations are completed within a few days, with minimal disruption and no major structural work required.
