HexEnergy Ltd have recently competed a project where a 8kW Danfoss Ground Source Heat Pump was installed as a complete heating and hot water solution for a two bed detached house in a remote farmers field. Our customer is a Shropshire farmer who has built a house for his parents to live in on their retirement.
With 400m of collector the Ground Source Heat Pump system will deliver heating and hot water running costs well under 1000.00 a year. Heating is delivered via an underfloor heating the system promises to deliver efficiencies which make the nearest comparison fuels of oil and bottled gas incomparable.
HexEnergy Ltd recently installed two Daikin Altherma 14kW Low Temperature Air Source Heat Pumps at Ferrybridge Power Station. This is an ideal heat pump in cold weather, the Daikin Altherma LT Split has exceptional frost protection, so it ?s guaranteed to perform in severe weather down to -25 C.
Benefits for the new Daikin Altherma low temperature heat pump include advanced technology offers both high savings and a comfortable room temperature. How? By matching capacity with requirements, using the most energy-efficient components, and managing performance with intelligent controls. Building a new house? Improving the energy efficiency of your existing home? The Daikin Altherma system is the ideal solution. It consolidates heating, cooling and domestic hot water in one system, providing maximum comfort all year round.
If you ?re looking for an all-in-one solution, Daikin Altherma has the answer. The indoor floor-standing unit combines heating and cooling with domestic hot water heating. The compact unit has a small footprint, but it offers big benefits. The Daikin Altherma system includes simple levels of control, with features such as advanced energy management. Yet the large display panel has been designed for the user. You ?ll find it easy to understand and simple to operate.
HexEnergy Ltd have replaced a working 35 year old heat pump with a new one to gain from better performance. The old unit was a predecessor to the Danfoss units now on the market. It has been replaced with the latest heat pump on the market which is a Danfoss 12kW Opti-Pro. This type of heat pump uses the existing collector loop to produce abundant hot water at 60C and heating at 22C to serve the large domestic radiator fed property in Warwickshire,. The photograph illustrate how new heat pumps are both compact and efficient compared to the old unit. The original Heat Pump was a Thermia JBC400M and dated from about 1977.
HexEnergy Ltd are currently doing the ground works for a 16kW Danfoss install near Newark Notts. Using a trenching machine to create a 1m deep hole in the ground the system is laid in record time with the minimum of disruption. The collector field is a normal paddock which is trenched over its full length to provide 16kW of heat for the property. The end of each pipe run is accessed via a jointing pit where the pipes are electro fused to ensure a sound joint.
HexEnergy Ltd and the University of Leicester are working on a collaborative project and Innovation Partnership - The project aim is to advise HexEnergy Ltd on the effectiveness of different system options for heat pump installations.
Objective 1 - Focussing on the collector loop, monitor the system performance at two (possibly three) installations, to determine the configuration that provides the largest opportunity for heat collection for the lowest electrical energy expense of the re-circulating anti-freeze pump.
Objective 2 - Determine the time-averaged Coefficient of Performance of the system and evaluate the impact of changing the collector configuration on the <CoP> by system modelling.
Objective 3 - By including appropriate energy forecast costs, produce projections of the Return on Investment (RoI) for different configurations, qualified by appropriate uncertainty bands that reflect the volatility of the energy supply cost and of the changes of the average heat delivered due, for instance, to a change in the client ?s lifestyle.
We at HexEnergy Ltd feel that this particular project was our masterpiece in promoting both our service and the heat pump industry in general.
The customer was deeply sceptical about the viability of heat pump technology, having been made aware of a local heat pump installation which had been badly installed and extremely expensive to run. Added to which the builder had no previous experience of heat pumps and as a traditional builder was sceptical of new technology.
HexEnergy Ltd were thus required to provide three similar sized reference sites for the customer to visit before they would even consider a heat pump solution. Having visited these sites the customer remained sceptical, unsure and very concerned about both the running cost of heat pumps and the ability of a heat pump to heat a large property and provide hot water by collecting energy from the ground.
Only on the promise of Richard Walkden, the Managing Director to provide the customers wife with a fur coat if the heating was not sufficient to keep her warm was negotiations able to begin.
The customer required 792m² of internal heating area at 210C and water heating based on a cloak room, kitchen and utility downstairs, five bedrooms and four en-suite ?s and a third floor kitchenette 500l of. Occupation was assumed to be based on five occupants using 50l each and allowing for at least two guests also using 50L each. As an active family there was a large requirement for hot water for washing machines and dish washers.
The timescales were to fit into the build program over the following 8 months and were perceived to not be at issue.
HexEnergy Ltd ?s MCS accreditation was significant in assuring the customer that the installation would be financially secure, designed properly, installed properly and supported after the installation.
The customer was insistent that one company take ownership of the heating from collection to delivery and HexEnergy Ltd were able to provide this service by providing the underfloor heating and ground loop system.

When the Hon MP for North West Warwickshire, Andrew Bridgen commissioned a new-build home, he was keen to utilise a renewable energy system that would reduce his carbon footprint and lower his energy bills.
The property was designed and built by Bridges Developments of Derbyshire, who specialise in low carbon properties and Managing Director John Bridges says: ?There were a range of challenges on this project, in particular the issue of achieving a high level of energy efficiency within a realistic budget. This involved a complete redesign of the original plan and we decided upon an innovative technique which used an insulated concrete form construction. This is a cost effective method of achieving a very high level of thermal efficiency.
Because of the high level of air tightness achieved by the concrete walls, HexEnergy Ltd was able to specify a 16kW heat pump, which is smaller than would usually be required for a new build property of this size and therefore uses less electricity ?.
HexEnergy Ltd MD, Richard Walkden explains: ?We were able to provide a highly cost effective solution for heating and hot water. This was achieved by using our bespoke design for the ground loop collector system which does not require a collector manifold ?.
Oak Tree Court is an exclusive development of nine luxury homes built by Chebsey Estates, an independent family run company, at the forefront of designing and building sustainable and eco-friendly houses.
Each five bedroom home is intelligently designed with space in mind, built with superior quality materials and fitted out to an extremely high standard.
When John and Sue Mackley planned a new build home for their retirement, they were determined to ensure that the heating system would be environmentally friendly and economic to run.
After several years of research on all aspects of the project, the couple commissioned their architect to design a five-bedroom house on their idyllic plot close to the village of Hose, near Melton Mowbray. Although the site is on mains gas, John and Sue were keen to reduce their dependence on fossil fuels and so decided to install a ground source heat pump.
