Maximise the return from your subsidy and reduce carbon emissions with the Evo’s high efficiency.
Experience the pros of renewable heating, hot water and cooling without the cons of pricey bills.
Leave the hard work to the Genesis System Manager – a clever system that optimises the Evo’s performance.
Enjoy peace and quiet with discreet sound levels and a sophisticated system that fits snugly inside the home.
Make and save money over the Evo’s lifetime. Depending on your project type, there is a range of funding options that we can advise you on. Visit this page to explore different types of funding.
Connect to the electricity grid without delay. The Evo’s Connect & Notify approval can save time and money.
Install the Evo with the ease of versatile features and a straightforward touch-screen set-up.
Choose the safe alternative to combustion fossil fuels and flammable refrigerant renewables. Like all Kensa products, the Evo uses a non-flammable refrigerant.
Boasting an A+++ Energy-related Product (ErP) rating, the Evo is our most efficient ground source heat pump. Its evolution sees a 15% gain in efficiency since its predecessor, maximising income from available subsidy.
The Evo’s high ErP rating means it delivers much more energy than it consumes from electricity – saving on heating bills, lowering carbon emissions and improving air quality. With an impressive 4.7 SCoP at 35°C, you’ll have top-mark heating no matter the season.
The Genesis System Manager takes the Evo to a whole new level of performance. As the world’s first ground source controller, the Genesis monitors and records efficiencies to help the Evo perform at its best.
Effortlessly integrating with all heating control systems, the Genesis allows flexibility for your heating to be as smart or simple as you like.
Matt Young – Installer, Griffiths Air Conditioning
The Evo system produces hot water up to 60°C*. Creating up to four times the energy it consumes, its high efficiency makes heating and hot water all-the-more affordable.
Working together with new or existing heating distribution systems, such as radiators or underfloor heating, the Evo delivers low-cost warmth to the home.
When summer finally arrives, you can even benefit from passive cooling as a useful add-on.
Throughout its 20-year design life, the Evo requires no servicing, needs little maintenance and produces next-to-no emissions. All the while maximising income from available subsidy for single-building projects.
With up to 5 years guarantee, the Evo has technical support for life for your complete peace of mind (terms and conditions apply.
See costs & paybackOur most intelligent and efficient heat pump is not only designed for peace of mind, but a peaceful environment.
The Evo’s noise levels range from 49.2 to 56.2 decibels (dB) – comparable in sound to the average dishwasher.
Geraint Roberts - Self Builder
The Evo series* is Connect & Notify-approved on the Energy Network Association’s (ENA) heat pump database, saving time versus most non-approved ground source heat pumps.
In most projects, approval means the installation can go ahead immediately; the local District Network Operators (DNO) don’t have to be notified until after installation. Approval almost always protects consumers from paying for an electricity upgrade.
*The 17kW is ‘apply to connect’ due to C&N’s 32A power limit, but meets the high standards of C&N approval – DNOs will usually cover necessary upgrade costs.
