Overview

Key advantages of the Kensa Q

For the highest of heat demands

Boasting three-phase, the series’ modular units provide flexibility to match and balance the heating demands of commercial buildings.

Ideal for cascaded systems

To efficiently meet fluctuating demands, multiple units can be connected together in a cascaded system.

Smart & compatible

Simple integration with new or existing radiators, fan coils or underfloor heating. Multiple units can also be controlled via a Building Management System (BMS).

Funding options

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.

Modulates to the highest heat demands

The series is comprised of modular three-phase models that deliver tailored outputs, flexibility and compatibility in large or commercial buildings.

The Kensa Q is the perfect candidate for a cascaded system. Efficiently fulfilling fluctuating demands, multiple units can work together to deliver large space heating and hot water demands at the same time.

With multiple heat pumps, heating and hot water can be provided to different parts of a building simultaneously through a Building Management System (BMS).

Designed for ease, the Kensa Q is compatible with a building’s heating distribution system, such as fan coils, underfloor and air handling units.

"It made sense to opt for this innovative approach to keeping [our buildings] warm and I am very pleased that the system is proving to be efficient and effective."

James Stockan - Orkney council chairman

Affordable, rewarding & reliable heating

Long-term savings

The Kensa Q offers low running costs, lack of annual servicing requirements and minimal maintenance over its 20-year design life.

Lifetime support

With up to 5 years guarantee, every Kensa heat pump comes with technical support for life. This includes anything from advice for installers to post-installation guidance for end users (terms and conditions apply).

Powerful yet power-saving

"As well as being energy-efficient, the technology makes perfect business sense compared to air source - which works out more expensive."

Charles - Garden centre owner

Just a fantastic company, with unparalled after sales service.I purchased a ground source heat... pump from Kensa 16 years ago, and the last couple of days I have had a problem with the programmer. Jordan, from their Technical Support Department was happy to spend a couple of hours on the phone with me today patiently talking me through the issues and getting my unit up and running again.What company is prepared to spend time on you these days,16 years after you last gave them a penny? How many would just refer you to an emergency engineer, if that!Kensa really are a first class British engineering success story. Great products and brilliant customer service. If you are thinking heat pump, ground or air source, you must contact them and put them in the mix in my opinion.read more

My Family purchased a Kensa Evo Heat Pump in 2020 and Project Managed its installation. It has been... everything we could have hoped for. Hot Water and Heating throughout our newly extended property on the Lizard.We have, however, encountered one ongoing problem, not with the Kensa Heat Pump but with the Immersion Heater fitted to the Advance Appliances "Super Duplex Hot Water Tank. The Thermco Immersion Heater pre-fitted to the Hot Water Tank failed after just four months (April 2021). Advance supplied a replacement and reimbursed our associated Plumbing costs. The replacement Immersion Heater, an identical model from a 2018 batch lasted just nine months, failing in January 2022. Advance supplied another identical Thermco replacement, again from the same batch. This time, they were reluctant to reimburse our Plumbing costs.Given that this ongoing failure could only be due to 1) a faulty batch of Immersion Heaters or 2) something in our Bore Hole water, we paid to have our water tested for Chlorides and found a low reading of 57 per mg/l (PVC guide max 250 mg/l). The second replacement Immersion Heater supplied by Advance, again, an identical unit, failed in March 2021 lasting just three months!We contacted Kensa Customer Technical Support in Truro and they were rightly concerned. They sent one of the excellent Team came over quickly as possible and emptied the Hot Water Tank, flushed and cleaned it and refitted a new Tesla Immersion Heater. He also took away photos and water samples for further investigation. We now await the results.It has been an extremely frustrating series of events that shows that, however excellent and efficient the Kensa EVO Heat Pump is - and it is!, a minor component of the whole setup can completely cause problems and, effectively, close the system down. We are indebted to Kensa Technical Support in Truro for getting involved and searching for the both the cause and the long term solution.Julian D Rand MBEread more

This is a comment about Kensa support.My 12-year-old heat pump developed an intermittent fault by... which the pump failed to start. It got worse over a few days until it no longer worked at all. (Not surprising in such an old machine).I phoned Kensa support and in seconds I had a diagnosis, and a new part was on it's way to me. As I didn't want to fit the part myself, the support people put me in touch with a local plumbing and heating expert. Unfortunately, he fell ill and took time off work, so my wife and I took on the task ourselves, following telephone guidance from Kensa support.Incidentally, when we first had the heat pump, we were confused about how to get the best from it, but we found out then that we could rely on them for help.Anyway, to fit the part we removed the front panel, then the top panel, but still we couldn't reach the failing part. We had to remove the back and side panels too - all the time following Kensa advice. Even then there were more problems. (I understand that newer machines are much easier to maintain.)We had been without heating for two weeks and frequently felt like giving up, but we sent photos by email to Kensa to illustrate difficulties as they arose and received solutions in return. Eventually we got the new part in place, switched on and felt the most profound sense of relief and satisfaction when the pump sprang to life.It should be emphasised that the support team are not necessarily familiar with such old models, but whenever we made contact all the support staff present knew about the problem. This gave a very reassuring feeling that we were getting an individual, personal service for which we are most grateful.In short, we received the most excellent telephone and email support for getting this very old heat pump working again.read more

Twice now they have sent out part replacements free of charge (when we are actually out of warranty) and have talked us through the installation in order to save us from calling out a plumber. Carl has been really really helpful, and Tom has also been excellent in the past.read more

Excellent ‘after-care’ and technical help on a product installed many years ago in a property I’ve... just moved into. It’s reassuring to be able to go through the heat pump and clarify my understanding and solve pressure issues simply by being talked through it all on the phone. Thanks for your time folk.read more

Had a really informative conversation with their Sales team. I was originally looking at installing... a ground source heat pump. However I was pointed in the direction of an air source pump which isn't one of their products but would be better suited for my property. Clearly putting customer service first! I would highly recommend you to get a quote from them.read more

Having had a lengthy search to find someone that actually knew what they were talking about when it... came to ground source heat pumps, we found Kensa. When we called we thought we were getting the receptionist, but in fact we got Daisy. She knew more about what she was selling than anyone else we had spoken to. Clearly knew her stuff, and instantly put our minds at ease. She worked out a detailed quote and nothing was too much trouble when we asked questions or wanted to change something.Installation was quick, clean, and everything was explained in a language we could understand. We were then given a complete system booklet, again explaining what to do if we have any issues or need to change anything on the systemDaisy and the whole Kensa team have been nothing but professional, capable and courteous from start to finish.Thoroughly recommend Daisy and the whole of the Kensa team to anyone who needs a GSHP.read more

We installed our heat pump in 2007, yes..13 years ago. It has been an excellent and reliable... investment that has performed exactly as planned. Support from Kensa can only be described as outstanding. Any call for support is quickly answered by knowledgeable engineers, who work with you to diagnose and resolve the fault or diagnose the issue and then send the right resources to fix the system. They clearly keep a sense of ownership and pride in what they make and install and are patience personified in the way they deal with lay customers. Top marks from me and thanks in particular to Tom with a recent sensor failure that proved difficult to identify.read more

We recently had a Kensa Heat Pump installed at our new build Hobbit Hole holiday let. Nothing about... this whole build was easy but we opted for Kensa for our renewable energy. Brilliant decision from the start, the product layout, working with our staggered delivery requests due to a just in time scheme adopted for the build, to literally holding our hand during the self installation process using a heat engineer locally. So helpful, and great to know if we need further guidence, totally confident they are there. John & Rebecca Garrett, Hobbit Hole, Abbotsham,North Devonread more

I chose Kensa Heat Pumps for our GSHP needs because Steve Costello and the other professionals I... met at home building events always welcomed me and answered all my questions. They introduced me to Howard Smith Builders in Herefordshire who installs many of their pumps and I visited him to see first-hand an installation Howard had done. Back to Kensa. All throughout the build and spec of our pump, Kensa stayed in touch and Steve even visited our home when the work began. I have also been assured that as and when there are software updates for their pumps, Kensa will provide them to me to ensure my pump stays at the optimum level. Thank you, Steve, and Kensa for sticking with me when I needed you to hold my pump for a year with no extra charge! Looking forward to having Lewington’s of Market Harborough finishing the install of your pump and slinkies this Wednesday!read more

Well, Kensa technicians continue to do a wonderful job. We installed our heat pump back in 2007.... Paid a fair price, got a grant towards the cost and have benefited from cheaper heating ever since. Any other boiler I am sure would have been on the scrap heap by now and the manufacturers not in the slightest bit interested in us. But not Kensa, they have continued to give first class technical support throughout the thirteen years - all advice free, friendly and helpful. We’ve bought a few bits, but not many and several parts have been provided free of charge. This time it was Todd doing the magic programming a new Corel for us, which he sent us by return at absolutely no cost to us. So anyone reading this - thinking of having a Kensa heat pump - do it! You won’t be sorry. Todd likened it to a land rover - sturdy, robust, efficient and long lasting and I think that’s absolutely right.read more

Can't recommend Kensa enough. Great product, phenomenal customer service. I called them after our... heat pump stopped working and spoke to an engineer called Tod. He was extremely knowledgeable and talked me through getting it going again over the telephone, even though turned out that the fault wasn't anything to do with the heat pump itself! Above and beyond, even messaged me again to check everything was still ok. Thanks Tod, you are an asset to Kensa!!read more

Similar to another reviewer, we bought Ground Source Heat Pump from Kensa some 10 or more years... ago. Never had any problems what so ever, until recently it fails to start and only rarely does it get up and going.Called the service desk, spoke to one of the Tom's, excellent knowledgeable advice culminating in us purchasing a replacement smart start box. I was nervous about doing the replacement, but encouraged by Tom, gave it a shot, it worked perfectly, job done !A couple of calls to the team always results in friendly expert definitive advice, everything breaks at some point, so its all in the recovery and the support team at Kensa have made recovery and service into an art form.The product is by design inherently more reliable than oil or gas boilers and the Kensa support experience confirms it was the right decision to buy the product.Congratulations.read more

Came across the invoice for our Kensa heat pump during a clear out. It cost us about £6k just over... ten years ago (+ digger hire for a few days) and I reckon it's saved us at least £750 per year since (probably closer to £1000). Maintenance cost so far has just been inhibitor for the heating system.read more

I bought a 10 year old house with a Kensa Ground Source Heat Pump last year. Recently, my hot... water has not been as hot as usual so I contacted Kensa for some advice. Bear in mind this is a 10 year old heat pump, well out of warranty . . . They could not have been more helpful!I have spent at least a couple of hours on the phone with Todd from their technical support team. He helped me troubleshoot, talked me through how to open the unit up and check things myself. He sent me some small parts free of charge and I also bought a couple of replacement parts, which he again talked me through how to fit.I have never come across a single company in my entire life that wouldn't charge me for this time. I'm well out of warranty and yet Todd did not hesitate to help. No bill for labour, just patient, friendly advice. What amazing service! Second to none!If I ever need another heat pump I'll be going straight to Kensa. Best customer service I've ever experienced!read more

* The COP figure quoted excludes the water pump electrical input and is calculated according to EN14511.
** In-built immersion heaters will increase running costs and CO2 emissions as they use direct electricity, because of this Kensa heat pumps do not include them.
*** By increasing the flow temperature from the heat pump the efficiency of the unit will drop and the COP decreases.
**** The starting currents are per phase. For full details on how the starting currents are calculated please contact Kensa.
Note: Design flowrates and pressure drops are based on a ground temperature of 0 and –3oC and a load temperature of 30oC and 35oC or 47° and 55°C.
