Solar Hot Water Investment in Devon: Making the Sun Work For You: 

As an environmentally conscious individual or business, you might have heard of solar hot water systems. Operating on the principle of converting sunlight into thermal energy, these systems are a cost-effective and sustainable solution for meeting your hot water needs. 

This article delves into the world of solar hot water systems, highlighting their benefits, costs, types, and working mechanisms.

An Introduction to Solar Hot Water Systems

Solar thermal systems, often referred to as solar hot water systems, harness the sun’s energy to warm water for home or business purposes. In contrast to solar panels that transform sunlight into electrical power, these systems absorb solar heat and convey it directly to water. This heated water is then stored in a tank or heat store, ready for use when needed.

How Solar Hot Water Systems Work

Solar hot water systems function using solar collectors, typically panels or tubes that absorb solar energy. These collectors are filled with a mixture of water and glycol, which heats up as it absorbs the sun’s infrared light. 

This heated fluid is then circulated through a circuit leading to the hot water cylinder, warming the water for use.

There are two main types of solar collectors used in these systems:

  • Evacuated Tubes: These are sets of glass tubes mounted on roof tiles, which are highly efficient at capturing solar energy.
  • Flat Plate Collectors: These can be either fixed on roof tiles or integrated into the roof, offering a more aesthetic appeal.

Your choice between evacuated tubes and flat plate collectors will largely depend on your budget, aesthetic preference, and the specific requirements of your property.

Is a Solar Hot Water System Right for You?

Before you decide to invest in a solar hot water system, you need to consider several key factors.

Assess Your Hot Water Needs

Firstly, assess your hot water needs. The size and capacity of the solar hot water system you choose should match your household’s usage patterns. 

For instance, if your family uses a substantial amount of hot water daily, you may need a larger system with a greater capacity.

Consider Your Property’s Suitability

Another critical factor is your property’s suitability for solar hot water system installation. The dimensions, direction, and amount of shade on your roof can greatly affect the performance of your solar panels.

It’s also crucial to consider the local climate conditions in Devon, as the sun’s energy varies depending on the season.

Evaluate Installation Costs and Payback Period

The installation cost of a solar hot water system typically ranges from £3,000 to £5,000, depending on the system size and the type of solar collectors you choose. Although the initial cost may seem substantial, it’s important to consider the long-term savings potential. 

With a solar hot water system, you can significantly reduce your energy bills and earn money from your hot water production through financial incentives like the Renewable Heat Incentive (RHI) scheme.

Understand the Maintenance Requirements

Solar hot water systems are generally low-maintenance. However, it’s recommended that they be inspected thoroughly every few years. 

This check involves draining and flushing the system and replacing the fluid to ensure efficient operation.

Benefits of Solar Hot Water Systems

Investing in a solar hot water system offers several benefits, including financial, environmental, and practical advantages.

Environmental Impact

Solar hot water systems use the sun’s energy to heat water, thereby reducing your reliance on fossil fuels. This helps to cut down on greenhouse gas emissions, making solar hot water systems a green choice for hot water generation.


Solar hot water systems are designed to meet around half of your hot water requirement. This means that while you may need a backup boiler or heater during the colder months or times of increased demand, you can rely on your solar system to provide most of your hot water throughout the year.

Future of Solar Hot Water Systems

The popularity of solar hot water systems in Devon and across the UK is on the rise, thanks to their financial benefits, reduced carbon footprint, and growing awareness about renewable energy solutions. 

As more individuals and businesses recognise the advantages of these systems, their use is expected to grow, further driving innovation and development in the sector.
