Air Source Heat Pump Installation

Expert Heat Pump Installers You Can Trust

At BioSun Energy, we specialise in professional air source heat pump (ASHP)installations for homes and businesses across Kent and Sussex. Whether you're upgrading an old heating system or exploring renewable energy for the first time, we provide a complete design and installation service tailored to your property.

Why Choose an Air Source Heat Pump?

Air source heat pumps are an efficient, low-carbon alternative to traditional boilers. They extract heat from the air—even at low temperatures—and use it to provide heating and hot water throughout your property.

Heat pumps are especially effective in well-insulated homes and can significantly reduce your energy bills. With the UK’s move toward greener heating solutions, they’re quickly becoming the future of home heating.

1. Comprehensive Heat Loss Survey

We start by carrying out a general calculation to size the heat pump and later we do a room-by-room survey. This helps us understand how much heat your property needs and ensures we specify the right size heat pump. A correctly sized system is vital for both performance and energy savings.

2. Tailored System Design

Every home and business is different, so we design each system to suit your property and heating preferences. Whether you use radiators, underfloor heating, or a combination, we’ll make sure your system is configured for optimal performance.

3. Clear Proposal and Running Cost Estimate

We’ll provide a clear, jargon-free proposal outlining:

• The full installation cost.
• Estimated running costs based on your home’s energy usage
• Any government funding (such as the £7,500 Boiler Upgrade Scheme).

This allows you to make a fully informed decision with no hidden surprises.

4. Top-Quality Equipment and Professional Installation

Our experienced engineers carry out every installation with precision and care. We handle all aspects of the job—including plumbing, electrical work,and smart control set-up—ensuring your system is up and running smoothly with minimal disruption to your home or business.

We install only high-performance heat pumps from trusted European manufacturers such as Vaillant and Stiebel-Eltron—brands renowned for their efficiency, durability, and excellent performance even in cold UK winters. These are purpose-built heating systems, not modified air conditioning units.

Is an Air Source Heat Pump Right for Your Home?

Not every property is the same. We’re honest about when a heat pump is a good fit—and when it isn’t.

Your home is likely suitable if:

• You have cavity wall and loft insulation
• You already have (or are planning for) double glazing
• You're replacing electric, LPG, or oil heating systems

We’ll assess your home and provide clear guidance. In some cases, we may even recommend improving your insulation first.
