Ground Source Heat Pumps (GSHP) are a highly efficient and eco-friendly way to heat and cool your property. As experienced local ground source heat pump installers, we can help you explore how this innovative system delivers reliable comfort all year round.
A GSHP works by using a ground loop, which is a series of pipes buried in the earth either vertically or horizontally depending on the space available. A special fluid circulates through these pipes, absorbing the natural warmth stored underground. This heat is carried to the pump unit, where it’s compressed to a higher temperature and transferred into your home’s heating system.
In winter, the system brings heat from the ground indoors, and in summer, it can reverse to help cool your property. It works efficiently with radiators, underfloor heating, or hot water systems, using renewable energy to keep running costs low.
As your trusted Ground Source Heat Pump specialists, we provide smooth installation and dependable maintenance to ensure long-term performance. Make the switch to a sustainable and cost-effective heating solution with our expert team.
What is a ground source heat pump and how does it work?
A ground source heat pump extracts heat from the ground using buried pipes called ground loops, which circulate a water-glycol mixture. The ground maintains a stable temperature of 8-12°C throughout the year, even when air temperatures fluctuate dramatically. The system works like a refrigerator in reverse – it uses electricity to power a compressor that concentrates the low-temperature heat from the ground, raising it to a higher temperature for your home’s heating and hot water. This process is highly efficient, producing 3-5 units of heat for every unit of electricity consumed.
Do ground source heat pumps work in cold weather?
Yes, ground source heat pumps are actually more reliable in cold weather than air source systems. Because the ground temperature remains stable year-round at 8-12°C, ground source heat pumps maintain consistent efficiency regardless of air temperature. Unlike air source heat pumps, they don’t experience reduced performance during cold snaps, making them particularly suitable for properties in exposed locations or areas with harsh winters.
How much will I save on energy bills with a ground source heat pump?
Ground source heat pumps are typically more efficient than air source systems, often achieving savings of 15-40% compared to modern gas boilers. When replacing oil, LPG, or electric heating, savings can be 40-60% or more. The higher efficiency of ground source systems means greater long-term savings, although the initial investment is higher. During our assessment, we’ll provide detailed estimates based on your current system, property characteristics, and usage patterns.
Will I need to replace my radiators?
Ground source heat pumps can typically provide higher water temperatures than air source systems (up to 55-65°C), making them more compatible with existing radiators. In well-insulated homes, your current radiators are often sufficient without modification. However, for optimal efficiency, we may recommend larger radiators or underfloor heating in some areas. During our survey, we’ll assess your current system and advise on any upgrades needed to maximize comfort and efficiency.
How noisy are ground source heat pumps?
Ground source heat pumps are significantly quieter than air source systems because there’s no external unit. The only noise comes from the internal heat pump unit, which operates at similar sound levels to a domestic boiler or large refrigerator. The pump typically produces around 35-45 decibels, making it suitable for installation in utility rooms or basements without noise concerns for neighbors or household members.
Do I need planning permission to install a ground source heat pump?
Ground source heat pumps often fall under “permitted development” rights, but requirements can be more complex than air source systems due to ground works. Planning permission may be needed for listed buildings, conservation areas, or if extensive excavation is required near boundaries. We’ll assess your specific situation during our survey and advise on any planning requirements or building regulations that may apply to the ground works and installation.
How much space do I need for a ground source heat pump?
Ground source heat pumps require significantly more outdoor space than air source systems for the ground loops. Horizontal loops typically need a garden area 1.5-2 times your property’s floor area, while vertical boreholes require less surface space but need access for drilling equipment. The indoor unit is similar in size to a large boiler and can be installed in a utility room, basement, or garage. We’ll assess your available land area and recommend the most suitable ground loop configuration during our survey.
