SRHA happy GSHP customers

Shropshire Rural Housing and Kensa Heat Pumps’ ambitious round of retrofit heating works under the Government’s Renewable Heat Premium Payment Scheme for Social Landlords have reported significant savings for tenants following a bi-annual review.

The installation of 63 ground source heat pumps installed under the RHPP social landlords programme has resulted in tenants experiencing immediate savings on their heating costs, as Bryan Powell, Chief Executive of SRHA, explains:

The objective of undertaking the installation of ground source heat pump systems in our homes is to give our tenants control over their heating, reduce their energy costs and invest in modern low carbon technology to reduce our carbon footprint. Feedback from our tenants has confirmed that this has been achieved as they now have control over their heating using the system to deliver better comfort levels at a reduced cost.

A small rural housing association with over 270 deeply rural homes throughout the county, SRHA’s asset management strategy demands an improvement in the thermal efficiency of their properties due to the largely off gas grid profile of their stock, which use night storage heaters as the primary heat source. Tenant complaints regarding the heaters’ running costs and lack of controllability – not delivering heat when needed – prompted SRHA to undertake a retrofit programme with the support of South West manufacturer, Kensa Heat Pumps, recently announced as the 10th fastest growing business in the South West’s Fast Growth 75 list.

Utilising the Renewable Heat Premium Payment Social Landlords Competition – a scheme set up as a precursor to the full Renewable Heat Incentive, which was subsequently launched in April), the initial cost of the ground source heat pumps were reduced, whilst attracting an income for 7 years through the Domestic RHI, creating an opportunity for Shropshire Rural Housing Association to efficiently and cost effectively transform the heating in a third of their housing stock.

Kensa co-ordinated the delivery of the works to a time sensitive schedule to ensure eligibility for the funding.

Bryan Powell, Chief Executive of SRHA, said:

This was an ambitious programme, for a business of our size, to help deliver affordable warmth to our customers. We feel that the substantial investment has proved to be very worthwhile and has met our objectives. We now have 89 homes – a third of our stock – heated in this manner delivering real benefits to our customers the Association and the environment.

Kensa’s Commercial Director, Chris Davis, says that social housing providers can profitably address their housing stock’s efficiency thanks to creative approaches to new Government incentives:

The success SHRA and Kensa have achieved under RHPP Social Landlords competitions demonstrate that renewables, and in our case ground source heat pumps, have a big part to play in improving tenant comfort and lowering fuel bills whilst delivering on key objectives for the housing association.

To build on this success, Kensa has explored ways that housing associations can effectively ‘cross-subsidise’ through the RHI and ECO, notably through the innovative application of micro district heating schemes in retrofit homes, allowing housing associations to access 20 years of RHI income plus an ECO subsidy to lower the initial investment cost in the heating system. Kensa would like to invite any social landlord looking at ways to tackle fuel poverty and heating system replacement in off gas grid areas to speak to us to see whether this might work for them.

Kensa Roadshow: The Case for Ground Source

Kensa Heat Pumps are taking to the roads of Britain this Autumn and Winter to help installers demystify the RHI and unearth the mysteries of ground source heat pumps.

The adventure begins in September and runs throughout October and November, re-commencing after the heating season in February and March 2015. Locations from Scotland to Cornwall will feature in Kensa’s 18 date UK tour, starting with Cambridge on the 10th September.

The events will help challenge and unmask misconceptions and myths of heat pump technology, alongside a general look at the renewable industry itself and the impact the Renewable Heat Incentive may have on installers’ customer bases, and ultimately their businesses.

Taking in both rural and urban locations Kensa’s Installer Roadshow will provide targeted events to both non-MCS/Oftec installers and MCS installers.

The Roadshow will enjoy support from Plumbase Renewables and the Department of Energy and Climate Change (DECC).

Lasting just three hours from 8:30am – 11:30am, each bite-size breakfast event will feed installers inquisitive appetites and delve into the truth about heat pumps and their place in the market.

Locations and dates of Kensa’s Installer Roadshow Events are as follows:

Birmingham, Fife, Surrey, Bristol and Carmarthen will host a further eight Installer Roadshow Events in February to March 2015. Further details will be released on Kensa’s events page at .

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

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.
