In this review, we look into the Kensa Evo ground source heat pump’s specs, pros and cons and cost so you can decide whether it’s the right solution for you.
Kensa Heat Pumps is the largest manufacturer of ground source heat pumps in the UK, and the Kensa Evo is one of the best ground source heat pumps on the market.
It has an A+++ Energy-related Product (ErP) rating and is Kensa’s most efficient ground source heat pump. With models ranging from 7kW to 17kW, there’s something to suit most household sizes.
The Kensa Evo is available in models ranging from 7kW to 17kW, so depending on the output you choose, it would suit small to medium households.
It’s not the quietest model on the market, running between 49.4dBA and 56.2dBA depending on the setting you use, but the noise levels remain comparable to a standard dishwasher.
Like other domestic ground source heat pumps, the Kensa Evo is installed via ground collectors or boreholes, where it collects heat from the ground or underground lakes to heat your home.
The Kensa Evo features a self-adjusting pressure controlled hot water system and domestic hot water boost controllers which synchronise to the heat pump cycles to reduce energy use. It uses a controller called the Genesis System Manager that monitors and records efficiencies so that the performance can be managed at all times.
This ground source heat pump can integrate with a number of heating control systems to allow for greater flexibility and customisation.
Kensa offers a few accessories (at an added cost). This includes different installation customisations, pond mats, purge pumps, underground and above-ground manifolds and more. Your installer will be able to provide more information based on your unique needs.
The price of the Kensa Evo ground source heat pump depends on the power output you opt for. Prices start at £7,660 for the 7kW model and go all the way up to £10,685 for the 17kW model. This places it on the more affordable side of ground source heat pumps, although you’ll also have to factor in installation costs on top of the unit price.
The Kensa Evo heat pump is a great option for medium-sized households, but if you’re after something more powerful, we’d suggest looking at the Viessmann Vitocal 350-G. It offers an output of up to 42.4kW and maximum flow temperatures of 70°C.
If, on the other hand, you’d like to go smaller (and cheaper), the Kensa Shoebox range is a good option. These highly compact ground source heat pumps have outputs of up to 6kW and are small enough to fit in kitchen cupboards, making them ideal for flats or small spaces. At around £4,000, they also suit smaller budgets.
As of November 2025, Kensa is rated an impressive 4.9 stars out of 5 on Trustpilot, although this is only from 90 reviews. On Google, the manufacturer is rated 4.8 stars out of 5 from just over 100 reviews. Customers express satisfaction with the heat pumps themselves, but also with the level of support offered by Kensa.
“Excellent service throughout and a very friendly team who really care about helping customers. The tech and support team, in particular Tom, have worked hard to make sure everything works well and the GSHP is running smoothly. We love it.”
“Tom was knowledgeable, understood how to lead me through the maze of the Evo and whilst we are not convinced we have found the problem we are on a path to resolution. I have full confidence that should the current part not solve the issue I know I can call back and get logical assistance to the desired performance that I’ve experienced from my heat pump this past 8 years.”
“We had installed a EVO 9 Heat Pump with ground loops in a new bungalow in 2020
Moved in in March 2021 pleased with system. Not as complex as some people think as they are a refrigerating unit working opposite way round. Now 2025 no problems with the system even the hot water is hot. My plumber installed it and I commissioned it over the phone to Kensa (I am an electrician). Would recommend system as it works well with underfloor heating system.”
a good range of power outputs, a very high efficiency rating and a reasonable price tag, we think the Kensa Evo ground source heat pump is a great choice for most households. It’s manufactured in the UK, making it a very sustainable choice. While there are better choices out there for small and very large homes, the Evo is a high quality middle-of-the-road heat pump from a trusted manufacturer.
We considered several factors when reviewing the Kensa Evo ground source heat pump, including the following weighted criteria: design (20 per cent), durability (20 per cent), efficiency (25 per cent), performance (25 per cent), and guarantee options (10 per cent). We also compared the Kensa Evo with some of the best outdoor heating systems and ground source heat pumps in the UK in terms of both performance and price.
