Whether you’re considering installation or simply curious about how it works, you’re in the right place. Let’s uncover the secrets behind heat recovery units and explore why they might be the solution you’ve been searching for.
How Does a Heat Recovery Unit Work?
A heat recovery unit transfers warmth from outgoing air to incoming fresh air, enhancing energy efficiency in heating systems. When warm, stale indoor air is expelled, it moves through a heat exchanger. The heat from this air warms the cooler outdoor air entering your home.
As a result, you maintain comfortable indoor temperatures without straining your heating system unnecessarily. The exchanged heat minimizes energy loss while providing clean ventilation. Another key feature of these units is moisture removal. They help balance humidity levels indoors, ensuring a healthier environment.
This method preserves energy and supports consistent airflow throughout your living spaces. It’s an intelligent way to harness existing thermal resources for improved comfort and reduced costs.
Types of Heat Recovery Unit
When exploring Heat Recovery Ventilation systems, it’s essential to understand the various types of heat recovery units. Each type offers unique features tailored to specific needs.
1. Plate Heat Exchangers
Plate heat exchangers are the most common type of heat recovery unit. They consist of numerous thin plates with alternating exhaust and fresh air flow channels. The plates are designed to transfer heat between the two airstreams without mixing them, thereby recovering heat from exhaust air and preheating incoming fresh air.
2. Rotary Heat Exchangers
Rotary heat exchangers use a rotating wheel made of a material with high thermal conductivity, such as aluminium or polymeric substances, to transfer heat between the two airstreams. As the wheel rotates, it alternately exposes the warm exhaust air and cold incoming fresh air to its surface, allowing for efficient heat exchange.
3. Run-Around Coils
Run-around coils use separate coils in each airstream connected by a circulating liquid, typically water or refrigerant. The heated or cooled liquid transfers energy between the two airstreams without allowing them to mix, making it an ideal choice for environments where cross-contamination is a concern.
4. Heat Pipes
Heat pipes are innovative heat recovery units that use sealed tubes filled with a working fluid such as refrigerant or water to transfer heat between exhaust and fresh air streams. As the exhaust air heats the liquid, it vaporizes and transfers heat to the cool fresh air stream, which condenses and releases the heat. The condensed liquid then flows back to the exhaust airstream, completing the cycle. Heat pipes are compact and efficient, ideal for smaller spaces or retrofit applications.
Benefits of Using a Heat Recovery Unit
A Heat Recovery Ventilation system offers homeowners many advantages. First and foremost, it enhances indoor air quality by exchanging stale air with fresh outdoor air. This process reduces allergens and pollutants, creating a healthier living environment.
Additionally, heat recovery units are energy-efficient. They capture the heat from outgoing air and warm incoming fresh air, reducing your heating bill significantly during colder months.
Moreover, these systems maintain consistent temperature levels throughout your home. No more chilly drafts or overheated rooms—just comfortable spaces year-round. Another benefit is their ability to control humidity levels. By managing moisture in the air, they prevent mould growth and protect building materials from damage.
