Air to water heat pumps are becoming one of the most popular heating solutions in Ireland. With rising energy costs and growing awareness of climate change, many homeowners are now switching to more energy-efficient systems. Air to water heat pumps offer a modern, eco-friendly way to heat your home and provide hot water all year round.
In this article, we will explain what air to water heat pump services are, how they work, their benefits, installation process, costs, and available grants in Ireland.
What Is an Air to Water Heat Pump?
An air to water heat pump is a system that takes heat from the outside air and uses it to heat water. This hot water is then used for:
- Radiators
- Underfloor heating
- Domestic hot water (showers, taps, etc.)
Even in cold weather, the system can extract heat from the air and convert it into useful energy for your home.
How Does It Work?
The system works in a simple way:
- It absorbs heat from the outside air.
- A compressor increases the temperature of that heat.
- The heat is transferred into water.
- The hot water is stored or circulated around your home.
This process uses electricity, but it produces much more energy than it consumes, making it highly efficient.
