Partner testimonial: Onninen Estonia

AS Onninen, based in Tallinn, is the leading technical wholesalers in Estonia and a key distributor for ES Energy Save. The company provides comprehensive product and service solutions for HVAC, electrical, and infrastructure professionals — supporting installers, contractors, and industrial clients with high-quality products, expert advice, and efficient logistics.

A growing heat pump market

The Estonian heat pump market has grown rapidly in recent years, driven by rising energy prices, greater environmental awareness, and supportive government incentives.

“Both residential and commercial customers are switching to more energy-efficient heating solutions,” says Lilia Winter, Product Manager for HVAC at Onninen Estonia. “We continue to see strong demand for air-to-water and commercial heat pumps.”

A partnership built on shared values

Onninen’s collaboration with Energy Save began in 2022 and has evolved alongside the expanding market.

“We were impressed by Energy Save’s strong focus on innovation, reliability, and Scandinavian quality,” says Winter. “Their products fit perfectly with our strategy to offer energy-efficient and sustainable solutions to our customers.”

According to Winter, the partnership is characterised by openness and mutual trust.

“We have a good dialogue and a shared goal to strengthen Energy Save’s presence in the Estonian market.”

Support that makes a difference

Energy Save’s training and technical support play an important role in Onninen’s customer success.

“Energy Save provides excellent technical support, marketing materials, and product training,” she says. “This helps our sales teams and installers stay confident and well-informed, which ultimately improves customer satisfaction and strengthens our market position.”

Looking ahead

With sustainability and energy efficiency at the core of future construction, Onninen sees continued opportunities for growth.

“The demand for energy-efficient heating and cooling systems is still growing, especially in commercial and industrial sectors,” Winter concludes. “Energy Save’s technology and modular solutions fit perfectly with future projects where flexibility, performance, and sustainability are key.”
