Buying Guide

a man testing a heat recovery ventilation system

As we explore the best heat recovery ventilation systems in the UK, it’s crucial to highlight the key factors you should consider when choosing a system. This guide covers some essential features to look for as you make an informed decision.

When selecting a ventilation system, efficiency is one of the most significant factors to consider. A high-efficiency system will transfer more heat between incoming and outgoing air. Look for systems that have a heat recovery efficiency of at least 85%. This will not only save on energy consumption but also contribute to a more sustainable household.

Next, we should consider the system’s airflow rate. The airflow rate depends on the size of your home and the number of occupants. It is typically measured in litres per second (L/s) or cubic metres per hour (m³/h). To maintain good indoor air quality, you’ll want to select a system that matches the airflow requirements of your home.

Installation ease is another crucial factor. Different systems have various installation methods, and some may require professional assistance. Keep in mind the available space in your home, as this will play a role in which system you choose. Additionally, pay attention to any maintenance requirements, such as accessible filters for easy cleaning.

Noise levels are also critical when selecting a heat recovery ventilation system. A noisy system could disrupt the comfort of your home. Aim for a system that operates at a noise level of 20 to 25 decibels (dB) or lower to ensure a quiet and peaceful environment.

Lastly, it’s important to take into account the system’s controls. Many modern heat recovery ventilation units offer convenient and user-friendly controls, such as smartphone apps or remote control options. You’ll want a system that provides flexibility and ease of use in managing its settings.

By considering these key factors, you’ll be better equipped to choose the best heat recovery ventilation system for your home in the UK. Happy shopping!
