Heat storage for farms and businesses.

Ecoways helps businesses turn surplus wind and solar energy into usable hot water, reducing energy costs and increasing self-consumption.

What is heat storage?

Most energy storage systems store electricity. Heat storage works differently.

Instead of storing electricity for later use, it converts available energy into heat and stores it as hot water. This lets you capture surplus energy when it is available and use it when hot water is needed.

For businesses with regular hot water demand, heat storage can:

  • Increase on-site consumption of self-generated energy
  • Reduce reliance on gas or electric water heating
  • Store heat for later use
  • Make better use of renewable generation
  • Improve energy independence
  • Support reliable hot water availability

Is heat storage right for your site?

Heat storage is particularly effective for businesses that use hot water every day and generate renewable energy on-site.

Dairy Farms

Hot water for cleaning, equipment, and daily operations.

Industrial and Processing Sites

Store renewable energy as usable process heat.

Commercial Buildings

Predictable hot water demand with lower reliance on traditional heating.

Hospitality

Reliable hot water for guests, kitchens, and facilities.

Every site is different. Ecoways assesses your hot water demand, renewable generation, building setup, and available space before recommending a solution.

Why work with Ecoways?

Heat storage is rarely a standalone decision.

It works best as part of a wider energy strategy that considers how your business generates, stores, and uses energy.

Ecoways looks at your solar panels, wind energy, battery storage, hot water demand, building setup, and available space to identify whether heat storage is the right fit for your site.

And if you need a complete system, we can help with that too. With many years of experience in wind energy, solar, storage, and smart energy control, Ecoways can design a setup that fits your unique needs.

Heat Storage FAQ

What is a heat battery?

A heat battery stores energy as thermal energy rather than electricity. The stored heat can later be used for hot water applications.

How is heat storage different from battery storage?

Battery storage stores electricity. Heat storage stores thermal energy for hot water and heating demand.

Can I use solar energy to produce hot water?

Yes. Surplus solar generation can be converted into heat and stored for later use.

How much hot water can be stored?

This depends on the selected system and your hot water requirements. The NEStore E30 can provide up to 910 litres of hot water at 40°C. If your requirements exceed this, then a network of multiple NEStore units may be an option.

Is heat storage safe?

Yes. Thermal storage systems such as the NEStore use water and stainless steel as their primary components and are inherently fire-safe.

Can heat storage work for my vacation park?

Yes. Heat storage can meet high and fluctuating hot-water demand while helping you electrify without increasing your grid connection. It can also reduce peak loads and make better use of your solar energy.

Can heat storage work for my dairy farm?

Yes. Heat storage can provide large volumes of hot rinse water at up to 80°C and recharge when your solar panels are producing energy. This helps you use more of your own renewable electricity and reduce energy losses.
