Looking to reduce your hot water bills and lower your carbon footprint? Solar thermal systems offer a smart way to harness the sun’s energy to heat water for your home or business and thanks to SEAI grants, they’re more affordable than ever.

In this guide, we explain how solar thermal systems work, what grants are available, who qualifies, and how EnviroBead can help you every step of the way.

What Are Solar Thermal Systems?

Solar thermal (or solar hot water) systems use roof mounted panels to absorb solar energy and heat a fluid, which transfers that heat to your hot water cylinder. These systems can provide 50 to 60% of your annual hot water needs, even in Ireland’s climate.

A typical setup includes solar collectors, a circulating pump, a hot water cylinder, and a controller. You still keep your existing boiler or immersion as backup. The result? Lower energy bills, fewer carbon emissions, and reliable hot water, all powered by sunlight.

Grants Available for Solar Thermal Systems

For Homeowners

Through the SEAI Solar Water Heating Grant, homeowners (including landlords) can claim €1,200 toward the cost of a new solar thermal system.

To qualify:

  • Your home must be located in Ireland
  • It must have been built and occupied before 2021
  • You must apply before installation begins
  • The work must be completed by an SEAI-registered contractor, like EnviroBead

This grant significantly shortens the payback period, especially when combined with lower energy usage and rising fuel costs.

For Businesses

Businesses and community groups can also benefit through SEAI’s Non-Domestic Solar Thermal Grant, which covers up to 30% of installation costs, capped at €15,000 per project.

This grant is available to-

  • Businesses of all sizes
  • Public sector bodies
  • Schools and community groups

Whether you run a hotel, gym, or facility with high water demand, this grant can help cut costs and boost your sustainability profile. EnviroBead can assist in both the application and the installation process.

Who Qualifies?

  • Homeowners: Most homes built before 2021 qualify. There are no income limits, and landlords are eligible too. You’ll need to go through SEAI’s application process before starting work, but EnviroBead can guide you through every step.
  • Businesses and Charities: If your premises has a significant hot water demand and you’re willing to install the system through a qualified provider, you likely qualify for the business grant. EnviroBead ensures the system is designed to SEAI standards and fully grant compliant.
