Ecoclime: Future-proof energy efficiency with circular heat energy

Full-service supplier Ecoclime helps customers reduce energy consumption in their properties. Its pioneering solution Evertherm, an industry-leading system for wastewater heat recovery, lowers energy use, reduces CO₂ emissions, and increases both property value and long-term savings. Most importantly, it recycles thermal energy that has already been paid for – heat from showers, washing, and cleaning – offering a powerful hedge against rising energy costs.

Ecoclime was founded with a clear vision: to harness the enormous amount of energy that is flushed away every day in buildings. “Wastewater contains large amounts of thermal energy from everyday activities like showers, dishwashing, laundry, and handwashing. That heat usually disappears straight down the drain,” says Robert Aldrich, CEO. “By developing and commercialising our patented solution Evertherm, a technology that recovers this energy, we’ve established ourselves as a pioneer in circular thermal energy.”

The company aims for zero-emission buildings – properties that are self-sufficient when it comes to thermal energy. Its first major milestone was the installation of Evertherm in the Nordic eco-labelled housing association Solterrassen in Umeå in 2018. The property, with 42 apartments, currently recovers 94 per cent of available heat energy from its wastewater.

Since then, Ecoclime has expanded through continuous technology development and strategic acquisitions. Its customer base spans both new production and existing properties, from renovation projects with major real estate actors to private tenant associations and municipal or state-owned properties. “We continue to grow with a clear focus on combining climate benefits with concrete profitability for property owners,” says Aldrich.

Evertherm, the pioneering circular solution

What makes Ecoclime unique is the circular, holistic solution Evertherm. It uses patented Swedish technology that recovers up to 95 per cent of the heat energy in a property’s wastewater – compared to just three to ten per cent for conventional solutions on the market. “Evertherm combines high recovery rates with long service life and reliability,” explains the CEO. “Instead of letting valuable energy go to waste, we recover energy that property owners have already paid for – making every kilowatt-hour count.”

HSB Brf Akvarellen in Tullinge, just south of Stockholm, installed Evertherm in 2024. Within a year, the association reduced its district heating consumption by 57 per cent – a saving that exceeded expectations. The combination of energy savings and long service life makes it one of their most profitable investments. In the words of the association’s chairman: “It’s almost too good to be true. It will be the best investment we’ve ever made.”

One of Ecoclime’s largest residential installations to date is Storfågeln, a 298-unit development by Heimstaden in northern Sweden. The buildings, designed to meet Miljöbyggnad Silver certification, use prefabricated timber-frame construction and two Evertherm systems to manage the high wastewater volumes. After just one year in operation, the installation has reduced the property’s energy use by more than 40 per cent — equivalent to 20 tonnes of CO₂ annually, or the fuel consumption of 120 petrol cars.

Stricter energy performance requirements

Ecoclime manufactures systems in Sweden for Swedish conditions, which strengthens quality, delivery capacity and service. “Another important success factor is our flexibility to either take responsibility for the entire chain – from feasibility study to commissioning – or collaborate with the customer’s contractor,” says Aldrich. “This provides security for the property owner.”

The Ecoclime team has several new projects underway, including Vacse and Specialfastigheter. “In parallel, we’re driving the development of more solutions within circular energy – always with a focus on combining efficient technology, profitability and climate benefits.”

Overall, there is an increased interest from new customer segments, especially considering rising heating prices and stricter regulatory requirements. More property owners see the importance of recovering energy, not only to reduce costs but also as a future insurance. “Evertherm helps meet the EU’s increasingly stringent requirements for energy performance in buildings,” adds Aldrich. “It’s a concrete way for property owners to future-proof their properties and reduce their climate impact.”

About Evertherm

Evertherm recovers the heat from wastewater that would otherwise go to waste – with up to 95 per cent efficiency. This is possible thanks to the unique combination of collector tanks, energy collectors using a patented polymer heat exchanger, and an advanced control system. No other system on the market offers the same degree of recoverability.
