Overview

Key advantages of the Commercial Range

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 Commercial Range is the perfect candidate for a cascaded system. Efficiently fulfilling fluctuating demands, multiple untis 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 Commercial Range 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 Commercial Range offers low running costs, lack of annual servicing requirements and minimal maintenance over its 20-year design life.

Lifetime support

On top of a 5-year 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.

Powerful yet power-saving

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

Great company and GSHP. After nearly 8 years of continuous operation our trusty heat pump developed... a fault. I called Kensa technical support services and despite having very little experience in this area was patiently talked through the investigation by Carl Jackaman until we had successfully diagnosed the fault. After fitting the required part, everything is now up and running again and I can not speak highly enough of their technical support services.read more

Have had a heat pump supplied by Kensa since our house was built 14 years ago. It has been... absolutely excellent. Extremely economical, without any servicing issues. A recent problem occurred when a capacitor failed. Technical support was immediate ( they replied to my enquiry with one hour ). They supplied the necessary replacement part over night. Special thanks to Carl (K? ) who was particularly knowledgeable,helpful and even telephoned to check that the repair had gone well. Can not praise him and Kensa enough. Definitely the best customer service we’ve ever experienced. Many thanks Carlread more

Recently had a 13 kw Evo installed and I am very pleased with its performance. In fact it is better... than my 12kw oil boiler which it replaced and it exceeds its quoted performance.. That said it would benefit with the energy meter being readable from the front panel which is over engineered being far to heavy/fancy and has to be moved to access same. Again the rear top cover could include preformed knockouts for the pipes or indeed be manufactured from a softer material to aid installation. I also think that the vibration noise although not loud could be improved by the use of plastic plumbing to connect to the 28mm fittings supplied since the vibration can be felt on my copper pipes and I would suggest that any new floor tiling beneath should be decoupled if possible from the screed and adjacent walls The weather compensator works well but would benefit from clearer installation/operating instructions. It would be interesting if the pump performance data held a retained average for the life of the machine. Additional detailed analysis of boreholes v slinkys would be of interest given that with increased energy costs I believe the cost benefit is worthy of analysis especially when drilling into granite. Overall- a great product and contrary to what the papers say there is plenty of hot water.read 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

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

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.

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!

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

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!

* 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°C and 55°C.
