Combined Heat and Power at its best

CHP - How to get started?

At SAV-Systems, we take care with the assessment of expected loads for any project proposal, to ensure there is good CHP potential. In particular, we spell out the expected benefits in terms of carbon reductions and cost savings.

 

We offer EC Power LoadTracker CHP gas units, each up to 15kW (e) and 30kW (th).  By using clusters of between 2 – 5 units, we can deliver up to 75kW (e) and 150kW (th) at any single installation. If the initial assessment shows that LoadTracker CHP would be unsuited to your site, we’ll be the first to say so! 

Besides supplying the DHW base load, LoadTracker CHP can also account for a significant portion of winter heating load. Two unique features make this possible: generator modulation down to 40% of maximum output (which allows continued operation in spite of low electric demand) and accurate control of thermal storage contents (which maximises the effectiveness of dealing with demand surges). 

LoadTracker CHP closely follows the fluctuations in site demand  over daily and seasonal cycles.  This dynamic response is instrumental to maximising LoadTracker CHP running hours and resultant savings! 

 

What happens next?

SAV-Systems look forward to helping with any aspect of LoadTracker CHP which may be useful to you.  Whether it is :

• To request initial information,
• To discuss project specifics,
• To arrange for a CHP assessment to be carried out,
• To carry out a pre-installation visit,
• To investigate options for boiler replacement,

LoadTracker CHP – Help at every stage

As the need to implement low carbon technologies becomes increasingly earnest, LoadTracker CHP can secure appreciable cost savings and significant reductions in CO2. Housing projects must undergo SAP (Standard Assessment Procedure) to calculate site emissions, with consultants now aiming for at least Level 3 of the Code for Sustainable Homes. Non-residential buildings such as schools, leisure centres and care homes are subject to BREEAM (Building Research Establishment Environmental Assessment Method), which in turn is based on SBEM (Standard Building Energy Modelling). One of the vital estimates given by this is for carbon reduction. LoadTracker CHP contributes valuable points to both methods, helping significantly to get project after project past Planning Approval.  Where necessary, SAV-Systems can improve its contribution further by offering the Low NOx version of LoadTracker CHP.

SAV-Systems take care with the assessment of CHP potential for each project, by looking in detail at the expected site loads (both thermal and electrical). CHP Energy Centres are based on EC Power natural gas units of 15kW (e) – 30kW (th).  LPG versions can be specified if necessary. By using clusters, up to 75kW (e) – 150 kW (th) can be provided at any single installation.

When preparing layouts for Energy Centres, SAV-Systems can draw on various plant combinations.  LoadTracker CHP units are frequently deployed as preheat of return to main boilers. Alternatively, they can provide the major share of site thermal demand. Piping arrangements for each of these cases have very specific features.

For any project where LoadTracker CHP may be considered, SAV-Systems recognise the importance of effective pipe work layouts. Experience has shown the value of getting this right, to ensure that LoadTracker CHP running hours per day are maximised. SAV-Systems provide guidance and support in the preparation of LTHW schematics. Usually this is done by prior issue of typical layouts, with subsequent review of draft versions as issued by the consultant.

 

 

Once the project opens at site, SAV-Systems can provide continuing support through an installation partner, either by providing advice only or by carrying out the complete CHP installation. After commissioning, annual servicing is offered at reasonable rates. Each LoadTracker CHP unit is monitored remotely for the client’s peace of mind. 

It is virtually unavoidable that many buildings will undergo refitting, extension or even change of purpose during their lifetimes. Regardless of how accurately a CHP installation may have been sized at outset, it is a near certainty that the daily and annual patterns of site heat / electricity demand will change.

That’s why SAV-Systems ensure that each LoadTracker CHP installation can vary production to keep in step with changing demand. If faced with a situation of increased load, a LoadTracker Energy Centre can readily be strengthened by inclusion of additional units.  In contrast to large, fixed output machines, SAV-Systems Energy Centres are highly flexible. This is reflected in lower energy costs and sustained asset usage.

Incidentally, where LoadTracker CHP units are part of a community heating system, the company offers a range of FlatStation Heat Interface Units for the consumer end. Energy metering and billing can easily be included, to provide an integrated system approach.

 

LoadTracker CHP – Whats it’s pedigree?

EC Power in Denmark started off in 1994.  Backed by serious R & D funding from energy giant Statoil, a series of high performance CHP units were developed and have benefited from a programme of continuous improvement. The flagship XRGI 15G CHP unit was launched in 2008 and has built up a solid track record.  In EC Power’s main European market (Germany), this machine overcame stiff competition to win the 2008 Mini-CHP of the Year Award.

In early 2009, EC Power formed a joint venture with SAV-Systems in the UK. This has enabled the technical strength of EC Power to be combined with the practical expertise and service-led approach of SAV-Systems. Currently there are approximately 140 LoadTracker CHP installations in the UK, growing steadily all the time.

 

LoadTracker CHP – Why is it different?

LoadTracker CHP is powered by a Toyota gas engine of proven reliability. It is designed for low maintenance and operates for 8,500 hours between services. The generator can modulate output down to 40% of maximum; this is very significant to continuing operations during periods of low electric demand. 

The CHP heat exchanger circuits are arranged to maintain flow water at constant temperature (usually 85C), regardless of return conditions.  This makes for steadier operations.  Every LoadTracker CHP comes with a thermal storage vessel, and the contents of this are kept as close as possible to flow temperature.  This maximises the impact of thermal storage in dealing with peaks in demand.   When site demand falls away, hot water is diverted to build up unused storage volume.

 

LoadTracker – What happens after installation?

Every LoadTracker CHP unit comes provided with remote monitoring.  Valuable information on running conditions is displayed in real time on a secure web-site. This means that facilities managers can check the status of any of their LoadTracker CHP machines, without first having to leave their office. Access to the website comes as part of the servicing agreement.

In the event of a fault (yes, these can happen!), status codes on screen enable rapid diagnosis.  Instructions for corrective action can then be passed to site staff, thus reducing downtime to a minimum. Servicing of the LoadTracker CHP units is only required annually and is offered at reasonable rates.
