A strong advocate and example of British engineering, the 15 year established Cornish-based manufacturer, Kensa Heat Pumps, has recently joined a national campaign to champion British industry as part of a major re-brand.

The ‘Made In Britain’ campaign, which sees Kensa sit alongside fellow supporters including VanGuard and Stoves UK, aims to ‘enable customers to identify British made products, supporting & promoting British manufacturing in the UK and overseas.’

Kensa aims to promote its support of the campaign alongside new marketing collateral and online resources resulting from the company’s recent re-brand. Stephanie Gregory, Marketing Manager explains:

“We have found that the significance of a British made product is a huge attraction to Kensa customers. By aligning ourselves with a national campaign this provides us with a recognisable marque to easily communicate our heritage and place of manufacture, as well as demonstrate our support for a British fulfilment channel and commitment to British engineering at its best.”

Marking its 15th year as a British manufacturer, Kensa Heat Pumps has completed a group restructure, company re-brand and new website, in a bid to prepare the company for what it believes will be the ‘most influential and significant of its history’.

“Our group restructure and re-brand provides our customers with clarity and familiarity across our companies. The launch of a new website supports Kensa’s position as the UK’s leading knowledge-base for all things ground source heat pumps, and now is by far the most comprehensive online resource dedicated to our technology, vital for our growing installer network and end users alike.”

“The launch of the domestic RHI and clarification of tariffs for the non-Domestic RHI, coupled with opportunities through the Green Deal and ECO, should ensure that 2014/15 will be the most significant in the history of the ground source heat pump market, and Kensa intends to be at the forefront of innovating and delivering solutions that enable our customers to get the most in return. The timing of our 15th anniversary could not be more apt – we hope this will be a year to celebrate!”

6KW Shoe In For Success

Posted by & filed under Latest News, Shoebox Range.

Kensa Shoebox Twin ground source heat pump

The UK’s leading manufacturer of ground source heat pumps has added another innovative solution to its award-winning product range for communal dwellings in the shape of the 6kW Shoebox Twin.

Kensa’s latest product is an evolution of the award winning 3kW Shoebox heat pump – and it’s packing some big punches in a small footprint.  The 6kW Twin boasts a greater capacity and heat output than its sibling Shoebox 3kW,but crucially is still capable of being sited within tight spaces inside a dwelling. And through the use of twin compressors delivers domestic space and water heating to larger new build and retrofit well insulated retrofit apartments and medium sized houses.

This small but mighty GSHP offers an impressively low acoustic output, and at 560mm x 605mm x 565mm is a particularly attractive solution where the only option available is to locate the heat pump inside the dwelling, such as within an airing cupboard.  Using a single phase electrical connection and the ability to provide water flow temperatures up to 65°C, the Shoebox Twin provides weather compensated space heating flow temperature control, plus the ability to satisfy a dwellings entire domestic hot water requirement without the need for costly supplementary electric back up heating.

Crucially, the Shoebox range provides Housing Associations and developers the unique opportunity to plug into Government subsidies such as the Renewable Heat Incentive and is ideal for use in projects featuring Kensa’s innovative “micro-district heating” approach, which significantly enables access to the lucrative non-Domestic RHI for new build applications, plus the additional possibility to attract an ECO subsidy in retrofit applications, especially where electric night storage heating systems are being displaced.

Chris Davis, commercial director for Kensa Heat Pumps comments:

“The introduction of the Domestic Renewable Heat Incentive and recently uplifted tariffs for ground source heat pumps under the Non Domestic RHI has seen a significant upsurge in the demand for ground source technology, where the benefits of highest efficiency, lowest possible running costs, permitted development planning rights and low noise nuisance are increasingly becoming recognised.  The Shoebox and Shoebox Twin meet the growing market need for small, efficient, quiet and cost effective solutions which can be applied in innovative ways to maximise the funding opportunities for housing associations, developers and home owners.  The original 3kW Shoebox has proven ideal for small, new build developments, however the higher output from the Shoebox Twin now opens up more and more opportunities for larger new builds and the retrofit sector.”

Thanks to its small size and low noise output, the Shoebox Twin has already been specified for installation on a number of retro-fit social housing projects and is also currently being promoted through Kensa’s ‘Underground Network Partners’ scheme, ensuring quality and professional Kensa approved installations. Installers wishing to sign up to be a Kensa Underground Network Partner, and enjoy exclusive access to new Kensa products like the Shoebox Twin before wider release, should visit www.kensaheatpumps.com/undergroundnetwork.

District heating in apartments and flats with Kensa's Shoebox heat pump

Ground source heat pump market leader Kensa Heat Pumps has welcomed the long awaited tariff increases for ground source heat pumps (GSHPs) under the Non Domestic Renewable Heat Incentive (RHI), following an announcement by the Department of Energy and Climate Change on Wednesday 28th May.

Under the non-domestic stream of the RHI, residential district heating schemes and installations in the non-domestic sector receive payments over 20 years for the renewable heat they generate.

Following extensive lobbying from Kensa and other members of the ground source industry, the previously ineffective tariff of 4.8p/kWh has been significantly increased to a Tier 1 rate of 8.7p/kWh (paid for the first 1314 full load equivalent run hours) and 2.6p/kWh thereafter.

“The uplift to the non-domestic RHI ground source heat pump tariffs will undoubtedly kick start the market for a technology which up until now has seen very low uptake under the RHI” said Chris Davis, Commercial Director of Kensa Heat Pumps.  “Ground source heat pumps are a well-established technology, with proven energy cost and carbon saving credentials, so the enhanced tariffs will level the playing field in the market compared with other renewable heat technologies and ensure ground source heat pumps can be considered a viable and financially attractive proposition for businesses, public sector organisations, care homes, schools and many other non-domestic applications.”

The non-domestic RHI also applies to district heating systems, an approach Kensa has innovatively adopted as a solution for the social housing sector.  “Combined with a capital subsidy from ECO funding, the uplifted non-domestic RHI tariffs for ground source heat pumps make Kensa’s “micro-district” solution increasingly attractive to the social housing market,” explains Davis. “The recently announced domestic RHI seems unlikely to be especially appealing to the social housing sector, however using Kensa’s unique approach of individual ground source heat pumps in each dwelling connected to a communal ground array, the enhancement of the non-domestic RHI tariffs creates an attractive opportunity for social housing to benefit from a financially compelling return on investment for a heating solution that will reduce both tenant fuel bills and overall operating and maintenance costs”.

Kensa’s UK manufactured ground source heat pump range covers models from 3kW to 75kW, including the award winning 3kW and 6kW Shoebox models and single phase units with outputs up to 24kW.

Lord Taylor and Kensa Heat Pumps

Kensa Heat Pumps has announced Lord Taylor of Goss Moor as its new Chairman.   Lord Taylor’s appointment will be instrumental in the Cornish company’s growth as the nation’s leading supplier of ground source heat pumps – the environmentally friendly renewable heat source that offers lower running costs than gas.

Commenting on his appointment, Lord Taylor said:

“Kensa is firmly established as the country’s leading supplier of ground source heat pump systems and has exciting plans for the future.   As both an environmental champion and a champion of affordable, sustainable homes I have been a long-standing supporter of the benefits of Ground Sourced Heating.  I also have a keen interest supporting ambitious Cornish companies. As the Government’s improved renewable heat incentives make ground sourced heating technology extremely competitive, especially for rural householders without mains gas, there is a huge opportunity for many more people to benefit.  Increasingly, Kensa has been working with major energy companies, High Street retailers, and other national stakeholders who see significant business opportunities in the years ahead, and I think they are right. ”

A long-time advocate of ground source heat pump technology, Lord Taylor is extremely knowledgeable about housing issues, having been commissioned by both the last Government and the present one to lead reviews of housing and planning policy. Himself a national award winner for his Parliamentary environmental campaigns, in 2007 he was appointed by the then-Prime Minister to produce a widely-acclaimed report on planning reforms to support the rural economy and housing. Currently he is leading a group advising the Government on renewing all its planning policy guidance.  He is also the Chairman of the National Housing Federation, the body representing England’s 1100 Housing Associations.

Kensa’s Managing Director, Simon Lomax, comments:

“Lord Taylor is nationally well-respected in areas of particular relevance to Kensa.  He is extremely keen to support ambitious companies in the environment sector that can genuinely both improve the environment and cut the cost of heating for households. With his national reputation across the housing sector in particular he will be able to contribute hugely towards Kensa’s growing success.”

Shoebox 6kW ground source heat pump

Cornish SME Kensa Engineering led the way for small businesses and niche innovations at the recent South West Green Energy Awards, securing the title of ‘Business Innovation of the Year’ for the company’s newest innovation, the Shoebox Heat Pump.

The Shoebox is the latest product to be manufactured by Kensa who, approaching their 15th trading year, has grown to become the most successful UK manufacturer in the heat pump market.

Kensa’s Shoebox Heat Pump won the coveted ‘Business Innovation of the Year’ title at the SW Green Energy Awards, hosted by Regen SW and held at the Bath Assembly Rooms on Tuesday (26th November). The miniaturised appliance is the smallest and quietest heat pump on the market, which means that that the renewable technology can – for the first time – be installed inside a dwelling, creating a major new market opportunity.

When combined with Kensa’s communal ground array, the Shoebox also receives an annual income through the Renewable Heat Incentive (RHI) and it is expected to play a significant role in helping the government achieve its target of installing 6.8 million heat pumps by 2030.

Kensa’s Managing Director, Simon Lomax, who was presented the award at the event, comments:

“We’ve created a new opportunity with the Shoebox that will hopefully lead the mainstream take up of renewable heating in domestic households.  Winning this award is recognition of exceptional work from a team of the industry’s very best engineers.”

Stephanie Gregory, Marketing Manager for Kensa adds:

“Like other successful SME’s, Kensa is often wrongly under-estimated by larger competitors – and we can use this to our advantage. Being a small business is not a weakness, rather we see our business as a ‘concentrate’, a ‘purée’ of specialists if you like; we employ the very best and focus our skills, experience and expertise to sustainably grow the business and continually deliver award-winning innovation, all from our headquarters based in Truro. The Shoebox is proof that size does not matter!”

Production of the Shoebox at Kensa’s Cornwall HQ has resulted in a 33% increase in production staff in the past 12 months.

Kensa Engineering, the UK’s No 1 manufacturer of ground source heat pumps, has been crowned Business of the Year at the Western Morning News Awards.

Announced in front of a crowd of over 330 South West business

Kensa Engineering’s Shoebox heat pump, the smallest and quietest ground source heat pump in the world, was also shortlisted for Innovation of the Year at the awards. leaders and innovators on Thursday night (21st November) at a glittering event in Plymouth, the title of Business of the Year coincides with Kensa celebrating its 15th anniversary in 2014.

Judges found the category of Business of the Year so closely contested that a highly commended award was created for runners-up South West Metal Finishing. Surfwear brand Ann’s Cottage were also a finalist in the category.

What set Kensa’s entry apart from the rest was the company’s sheer tenacity, commitment to innovation, and drive.  As Simon Lomax, Managing Director of Kensa Engineering comments:

“Approaching our 15th anniversary we couldn’t have asked for a more appropriate end to 2013. In the last five years we have seen Kensa’s turnover increase five fold, and staff numbers increase by a third in 12 months.  This performance is made even more remarkable due to the overall ground source heat pump market declining during this period due to delays in government subsidy programmes.  Regardless of such delays, Kensa is now the UK’s largest supplier of ground source heat pumps, out-performing global and pan-European competitors. With hugely rewarding Government programmes finally released for ground source heat pump customers, and our recent appointment of Chris Davis as our new Commercial Director, Kensa is on the cusp of an expected boom; the outlook for 2014 is hot!”


Kensa’s win should increase awareness of the alternatives to traditional fuel types, and the benefits of renewable technologies. With news of potentially the coldest winter for a generation and recent price hikes by the major energy companies, many living off the gas network will be looking for a way to reduce bills and guarantee their warmth through the winter, as Simon continues: 60°C

“The market for ground source heat pumps is near boiling point. We are all poised for the RHI Phase 1 tariff increases and RHI Phase 2 launch in Spring. Added to this the expected plummeting temperatures through the winter, we expect demand for ground source heat pumps to peak, and Kensa is aligning itself to best maximise the opportunity for installers, end users, and industry.”

New Hybrid GSHP engineered by Kensa

Posted by & filed under Latest News.

Kensa twin compact ground source heat pump square

Kensa Heat Pumps has created a new Hybrid ground source heat pump to add to its British-made product range, addressing cost concerns and peak heating and hot water demands of larger new builds and well insulated homes.  The Hybrid ground source heat pump is available in 15kW and 21kW single phase models; some of the largest single phase ground source heat pumps available on the market.

Kensa’s twin compressor Hybrid heat pump harnesses the properties of two separate refrigerants in its compressors to deliver heat outputs similar to those provided by Kensa’s Standard models, along with hot water temperatures typically produced by their High Temperature models. This blended design allows customers to enjoy both defining benefits of Kensa’s product ranges in one affordable unit.

The motivation for the creation of the Hybrid was capital cost, as Guy Cashmore, Technical Director of Kensa Engineering continues:

 “The properties of different refrigerants can meet specific needs, but each come with a compromise. For example, Standard Kensa models use R407C refrigerant to provide space heating outputs but as a result hot water temperatures are compromised to approx 50°C. The introduction of R134a refrigerant transforms the Standard into a High Temperature model, allowing the unit to produce hot water up to 60°C, but this reduces its space heating output. So to achieve space heating demand and hot water up to 60°C, traditionally we supplied a High Temperature model with a larger compressor to allow for the de-rating in the systems space heating output, which regrettably cost the customer more money.”

 “The Hybrid provides both space heating (up to 50oC) and hot water (up to 60°C) by using both refrigerants, one in each of the unit’s compressors. This removes the need to increase the compressor size of the unit to compensate for any de-rating in heat output associated with pure High Temperature refrigerant, and as a result saves the customer money .”

To deliver space heating and hot water the first compressor in Kensa’s Hybrid uses Standard temperature (R407C) refrigerant, whilst the second compressor uses High Temperature (R134a) refrigerant. Both compressors work together to deliver the space heating. When producing hot water, both compressors work together initially, but once the hot water gets hotter than the Standard temperature compressor’s return temperature set point, this compressor turns off. The compressor with the High Temperature refrigerant then takes over on its own to provide an extra 15°C to the hot water cylinder.

The Hybrid also usually removes the requirement to periodically heat the cylinder with an immersion heater to pasteurise the hot water.

Five social housing providers in the UK will be able to embark on a programme of renewable heating works in their housing stock thanks to successful joint bids with ground source heat pump manufacturer, Kensa Engineering, for government Renewable Heat Premium Payment (RHPP) funding.

The RHPP Fast Track funding secured by the five social housing providers benefitting from Kensa’s support equates to over £2m of a total £7m funding pot.

Kensa continues to work in collaboration with a number of social housing providers in order to secure additional funding through the second RHPP ‘Reach Out’ Social Housing Competition, which offers less demanding timescales but with a funding cap per project, limiting the total funding available per project to £175,000. The deadline for the Reach Out Competition is the 27th September, with the winners announced on the 14th October.

The funding available under both RHPP Social Housing Competitions is limited to social housing providers for retrofit renewable heating technologies in their housing stock.

Intended for pipeline projects ready to go, the Fast Track competition has attracted over 50 applications in total, seven of which are for ground source heat pump projects; Kensa Engineering was successful for all five of the five ground source heat pump projects it submitted.

Each bid was awarded funding based on its score against key criteria including value for money, energy savings, deliverability, and community engagement.

Shropshire Rural Housing Ltd, Devon & Cornwall Housing Ltd, Ocean Housing, Tarka Housing, and Yorkshire Housing Ltd are the successful social housing providers to submit a winning bid to the RHPP Fast Track competition with Kensa’s support. In order for the funding to be obtained, the retrofit ground source heat pump installations will be completed by the 31st March 2014.

Shoebox 6kW ground source heat pump

The unique strengths of Kensa Engineering’s innovative Shoebox Heat Pump are being recognised with numerous awards including the coveted title of ‘Product Innovation of the Year’ at the National Heat Pump Awards 2013. An ultra small and ultra quiet heat pump, the Shoebox provides a compelling alternative to traditional gas boiler installations in apartments and smaller new build houses.

Developed and manufactured by the UK’s market-leading ground source heat pump manufacturer, Kensa Engineering, a Shoebox heat pump is typically installed within a property’s under-sink kitchen cabinet and provides all the dwelling’s space heating and hot water requirements.  Most importantly, the recommended Shoebox system architecture features a communal ground array which satisfies the requirements of a district heating system allowing installations to benefit from Phase One of the RHI.

Simon Lomax, Managing Director of Kensa engineering comments:

“It is virtually certain that new build housing will be excluded from the domestic phase of the RHI so we wanted to launch a system that could attract support through the existing Phase One; this was the driver for the communal ground array design.  Of course, such a design means it is no longer necessary to provide an individual borehole for each dwelling: instead, a smaller number of deeper holes are drilled which reduces overall installation costs.  RHI payments are awarded to the social landlord or, in the case of private sector apartment blocks, the management company.  Given DECC’s decision to increase the RHI Phase One GSHP tariffs, there is an attractive rate of return.  Alternatively, Kensa can provide funding solutions.

“Unlike air source heat pumps which must secure permitted development rights or planning permission, ground source heat pumps can be routinely installed.  They also deliver the lowest possible running costs of any renewable heating system which means that developers can secure premium prices from purchasers seeking low energy cost homes.”

According to Stephanie Rees, Marketing Manager:

“Kensa is delighted to win this award.  Awards can play a significant part in elevating our reputation and market presence, and as the only UK manufacturer and current market leader of ground source heat pumps, we hope to continue to use these accolades to promote interest in our products.”

The Shoebox was announced the winner of its category at the National Heat Pump Awards held in the International Conference Centre in Birmingham on the 16th May 2013.
