Exhaust Air Heat Pumps (EAHP)

What are Exhaust Air Units?

An Exhaust Air Heat Pump (EAHP) is a smart system that improves your home's energy efficiency. Here’s how it works:

1. Ventilation and Heating

  • The EAHP ensures excellent ventilation by bringing fresh air in and expelling stale air.
  • It captures warm air from areas like your kitchen and bathrooms before it leaves your home.
  • This captured energy is reused to meet your heating and hot water needs.

2. Heat Recovery

  • Ducting hidden in the ceiling draws warm air through the heat pump.
  • The system extracts energy from the air before expelling it outside.
  • This process efficiently supplies the entire house with heat and hot water, creating a cozy indoor environment.

3. Compact Design

  • The EAHP is compact, about the size of a fridge-freezer.
  • Its sleek design fits perfectly into modern homes with limited space, like well-insulated flats or homes with underfloor heating.
  • Despite its small size, it delivers impressive performance.

Why Use an Exhaust Air Heat Pump?

Exhaust air heat pumps (EAHPs) are part of a broader category of heat recovery systems designed to boost energy efficiency and lower running costs. By extracting heat from indoor air, they ensure no valuable energy is wasted. Here’s why they are an excellent choice:

Consistent Heating and Hot Water

  • The system provides a dependable supply of heating and hot water, helping to reduce energy bills. You can enjoy warmth and hot water whenever you need it, making it an economical and hassle-free option for homeowners.

Environmental Benefits

  • By capturing and reusing heat that would otherwise escape, EAHPs optimise energy use and significantly lower your household’s carbon footprint. They are a greener alternative to traditional heating systems.

Improved Home Performance

  • Installing an EAHP can improve your home’s overall environmental performance. These systems help maintain better air quality, reduce moisture levels, and create a healthier living environment.

Real-World Application

We recently completed a project in Essex, fitting 15 new build flats with individual exhaust air heat pumps. This installation showcases the effectiveness and benefits of EAHPs in modern housing developments.

Each flat now enjoys improved energy efficiency, reduced running costs, and enhanced indoor air quality.

Advantages of Exhaust Air Heat Pumps

  1. Cost-Effective: They are cheaper to run than fossil fuel boilers, providing significant savings on energy bills over time.
  2. Eco-Friendly: EAHPs reduce your carbon footprint by creating less CO2 emissions, contributing to a cleaner environment.
  3. Prevents Condensation: Helps prevent condensation in your home, which can protect your property from mold and damp issues.
  4. Multi-Functional: Provides heating, ventilation, and hot water in one integrated system, simplifying home maintenance.
  5. Improved Air Quality: Keeps your house ventilated, which is crucial for well-insulated homes. Better ventilation leads to a healthier living space.
  6. Quiet and Low Maintenance: Operates quietly and requires minimal upkeep, offering peace of mind and convenience.
  7. Safe: Runs on electricity, making it safer than fossil fuel boilers that burn fuel, reducing the risk of leaks or combustion-related accidents.

Ideal Applications

An exhaust air heat pump can provide about 5 kilowatts (KW) of energy, making it suitable for new flats and small homes with good insulation and underfloor heating. This makes EAHPs particularly beneficial for modern housing developments that priorities energy efficiency and sustainability.
