COMPARISON OF AIR SOURCE HEAT PUMPS IN THE UK

Introduction

Air Source Heat Pumps (ASHPs) have become increasingly popular in the UK as a sustainable heating solution. These systems extract heat from the air outside and use it to heat homes and provide hot water. This book aims to provide an in-depth comparison of various ASHP brands available in the UK market, including Daikin, LG, Samsung, Vaillant, Grant, and Nibe, while ultimately demonstrating why the Mitsubishi Ecodan stands out as the best option.

AIR SOURCE HEAT PUMPS

What is an Air Source Heat Pump?

An Air Source Heat Pump (ASHP) is a system that transfers heat from the outside air to water, which can then be used for heating radiators, underfloor heating systems, or hot water in your home. ASHPs work similarly to a refrigerator in reverse, using refrigerant to absorb and release heat.

Benefits of ASHPs

Energy Efficiency: ASHPs are known for their high efficiency, converting energy from the air into heat with a higher efficiency rate compared to traditional heating systems.

Reduced Carbon Footprint: ASHPs use renewable energy from the air, contributing to lower greenhouse gas emissions.
