Can Solar Thermal Be Used in the UK for Domestic Hot Water?

2 March 2025

With rising energy costs and a greater focus on sustainability, many homeowners in Bath and Somerset are exploring renewable heating options. One such solution is solar thermal heating, which harnesses the sun’s energy to heat domestic hot water. But is solar thermal a viable option in the UK’s climate? The answer is yes!

How Does Solar Thermal Work?

Solar thermal systems use roof-mounted solar collectors to absorb sunlight and convert it into heat. This heat is transferred to a water cylinder, providing hot water for your home. Unlike solar PV panels, which generate electricity, solar thermal is specifically designed for water heating.

Is Solar Thermal Effective in the UK?

Despite the UK’s reputation for cloudy weather, solar thermal heating can still be an effective solution. Modern systems are designed to work efficiently even in overcast conditions, providing around 50-70% of a household’s annual hot water needs. During summer, solar thermal can meet almost all hot water demand, while in winter, it can be supplemented with a conventional boiler or heating system.

  1. Lower Energy Bills – By using free solar energy, you can reduce your reliance on gas or oil heating, leading to lower energy costs.
  2. Environmentally Friendly – Solar thermal significantly reduces your carbon footprint by decreasing fossil fuel consumption.
  3. Compatible with Existing Systems – Solar thermal can work alongside gas, oil, or electric boilers, making it a versatile addition to any home.
  4. Government Incentives – Homeowners may qualify for grants or incentives to help offset installation costs.
