Creda Heating

A low carbon future

a low carbon future.

“Creda continues to invest in the bright future of electric heating. The 2008 Energy Bill promoted the production of heating from low carbon electricity, as ever more central generation flows from low carbon sources. ”

Low carbon electricity, generated here in the UK and not imported from around the world, gives us security of energy supplies and contributes to reducing the devastating impact of climate change.

Low carbon electricity provides low carbon heating from electric panel and storage heaters. Creda are at the forefront of these developments with the latest technology, advanced energy-saving controls and contemporary styling to suit the homes

of today.

Part L and SAP

(Standard Assessment Procedure)

The April 2006 revision to Part L of the Building Regulations requires that all new buildings do not exceed a Target Carbon Emission Rate (TER) as measured by a Standard Assessment Procedure (SAP). For more details on how to comply see our ‘quick start’ guide on pages 6 & 7 of this brochure.

Every day, across the country, we design electric heating systems that improve SAP scores and achieve full compliance with Part L of the Building Regulations for buildings of all shapes and sizes. See page 5 for information on how!

Decent Homes and Sustainable Communities

By 2010, the government has committed to bring 95% of all social housing in the UK into a decent condition and the remainder are to be improved soon after.

The new Housing and Regeneration Bill has also committed the government to building 3 million new affordable and sustainable homes by 2020. The provision of modern facilities are along with the building improvements required to meet this legal obligation, brings energy efficiency to the fore. Improved air-tightness combined with new heating systems, kitchen and bathroom facilities and effective ventilation strategies will all be needed. Our sister brand Redring has a successful track record in providing affordable hot water and showering into Decent Homes projects (see www.redring.co.uk) and Xpelair are experts in the field of low carbon ventilation, with the Xpelair Carbonlite boasting a range of low energy and long-life product

(see www.xpelair.co.uk). Here at Creda we are the heating experts.

Warmth is a pre-requisite of decent housing and low carbon electricity is the route to sustainable communities. We believe electricity is the fuel of the future; homes built today may well last 60 to 100 years, so we must build for the future today!

Creda electric heating can meet and exceed the needs of the Decent Homes Standard. Our website provides on-line help, tutorials and CPD accredited courses for those wishing to ensure their development is compliant with the regulations.

Creda Heating

Design application support

Electric heating is cheaper than gas

Annualised installation costs (based on manufacturers’ quoted average lifetimes and typical installation costs for 6 electric panels or 6 wet-radiators and a

gas boiler).

Annual safety check and maintenance costs (to comply with manufacturers’ conditions of guarantee - using lowest priced British Gas service contract to include boiler, controls and radiators).

Annual fuel costs (based on guidance from the Energy Saving Trust publication CE185 and Npower standard gas and electricity prices on Feb 10th 2008).

Low carbon electricity from renewable sources makes electric heating the fuel of the future; but already electric heating is cheaper than gas.

In recent times all energy prices have risen but none more so than gas. Creda electric heating is now cheaper over its entire lifetime than gas, when all the facts are considered.

Electric heating products cost less to buy in the first place and are quick and easy to install or upgrade. They offer total flexibility in the building design, with no complicated pipe runs, which also leave gaps in the building fabric; a problem when air-tightness is a key factor in improving the carbon footprint of a building and meeting Part L of the building regulations. Once installed, electric heating requires virtually no maintenance. Unlike gas there is no legal requirement for an annual landlord safety certificate.

Year in and year out, electric heating provides instant, responsive and safe heating on demand. Recent calculations have shown that when all these factors are taken into account there is a minimum overall cost saving of at least 13% a year in comparison to gas central heating.

Apartments and flats often favour electric heating for all these reasons. It is the simplest and most cost effective solution for many hotels, gyms, crèches, nurseries, surgeries, care homes, offices and shops all over the UK.

Application design

We have over 40 years experience in designing and supporting electrical heating installations. We are able to offer an expert application design service for all our products, helping new and existing customers alike to specify Creda products into real buildings and live projects, either off-plan, commenced new-build or refurbishments.

In recent times the proliferation of environmental legislation and revisions to Building Regulations, all designed to reduce carbon intensity and improve energy efficiency, have made the design process more complex. We are here to help with two levels of design service.

Level 1:

Our standard design service is free of charge and will provide a clear and simple indication of the products required and the associated costs. This service can be provided from basic plans and drawings.

Level 2:

Our enhanced design service incurs a very competitive fee to cover third-party costs and a small contribution to the work of our accredited SAP assessors. In return a dedicated assessor will provide schematic designs and confirmation of regulatory compliance including Part L of the Building Regulations and a SAP score, as well as the product requirements and costs to achieve this. Full architectural drawings are required to complete this service and work cannot commence without them.

For further information send a description of your project, contact details and drawings to [e-mail]

Technical services

Our technical services call centre is staffed by a team trained in diagnosing and rectifying potential concerns over the phone.

If for any reason they are unable to solve a problem by phone, they will brief an engineer on your behalf prior to the service visit to ensure that, wherever possible, the problem is fixed first time.

The team also provides advice on product selection, application, installation and operation; ensuring maximum value is gained from selecting a Creda heating product.

Meeting Part L

The quick start guide!

Xpelair Xcell 270

“Electric heating continues to grow in popularity. In April 2006 the revision to Part L of the Building Regulations meant the way you comply for new buildings changed. This is the quick-start guide to complying

with Part L. ” Block Assessment

All the old methods of compliance have been abolished and replaced with a Target Carbon Emission Rate (TER).

Whatever fuel type you choose for the heating and hot water of your new building - gas, oil, LPG or electric - you have to show that the overall carbon emission rate is less than the target for that building type.

There are also new minimum standards for U-values and airtightness, which must be tested on completion of the building. However, even meeting all the minimum standards will not guarantee a pass.

The biggest change is that under the new rules the whole building is taken into consideration. Every factor that can influence carbon emissions is relevant and it’s the whole building that must pass.

So just building to minimum standards may not guarantee a pass because the whole building may still exceed the target

carbon emission rate.

What’s my target?

The target is set in terms of Kilograms of carbon dioxide for every square metre of the building, over the course of a year (KgCO2/m2/yr).

A range of sample buildings is used to set the target, which is then adjusted for the size and shape of the actual design and the heating and hot water plan.

The complex calculation of both the target and the actual score of your new building can be performed within special SAP 2005 approved software. (The government’s adopted Standard Assessment Procedure). An accredited SAP assessor is required to complete this.

The targets created under Part L 2006 demand a 20% reduction in carbon emissions compared with the previous rules. This new tougher target was set to improve the country’s energy efficiency and dependence on imported fuel and to reduce the devastating effects of climate change.

The tougher target applies to all relevant buildings, all products and all fuel types. It’s the whole building that must comply, not any given product or building service.

Part L 2006 has important rules for setting and achieving the targets in flats and apartments. So called ‘Block Assessment’ allows for all the flats or apartments in a building to be assessed in one go.

Each flat or apartment can be dealt with as the developer or specifier feels appropriate for meeting the overall TER, across the different floors and sides of the building. Any given flat or apartment does not have to meet an individual TER as long as the whole building does.

This allows the developer or specifier flexibility in how to achieve the target. For example, mechanical ventilation with heat recovery (see picture above) may be installed which would create carbon savings which can be shared out across the whole building.

It also reduces running costs and becomes a major selling feature. For more advice on saving energy see the guide at the back of this brochure.

Can you comply using electric heating and hot water?

Yes.

The only test for compliance is that the building does not exceed the target carbon emission rate. We continue to supply electric heating and hot water solutions into fully compliant buildings. Electric heating has also been shown to have lower lifetime costs of ownership than gas, is easier and quicker to install,

is maintenance free, offers great design flexibility and has lower initial capital costs.

Electric heating is the fuel of the future. Low carbon electricity from UK sources produces low carbon heating only with electric products.

How do I reduce the carbon emission rate of a building?

There are a number approaches that are proving most effective at reducing the carbon emission rate of a building. We recommend you consider the following options. In isolation or in combination, all of these options have been used in conjunction with modern electric heating.

Meeting Part L

The quick start guide!

Creda Eco-Response

1Improve the air-tightness:

It is now mandatory to test the air-tightness of a building on its completion. There are minimum levels required under the new regulations but improving on these has been shown to be one of the best ways to reduce the carbon emission rate and therefore comply with Part L. Electric heating is helpful in this regard as it results in less holes and gaps in the building fabric than gas heating systems. The regulations require a minimum air-tightness of 10 cubic metres per hour per square metre of floor area at 50 Pascals of pressure. (10m3/h/m2 @ 50Pa). Many developments can now achieve 7 or 5 and some even 3m3/h/m2 @ 50Pa.

2Install mechanical ventilation with heat recovery:

Used in conjunction with improved air-tightness, so called MVHR recovers otherwise wasted heat and is a great advantage to the ventilation strategy. There are specific provisions within SAP (Appendix Q) which show how using MVHR can reduce the carbon emissions rate and help compliance with Part L. Xpelair offers leading MVHR systems as part of the Carbonlite range,

see www.xpelair.co.uk.

3Improve the building fabric:

There are minimum U-values for all elements of the building fabric. U-values are a measure of how much heat energy can escape through a given element of a building. However, simply meeting these alone does not guarantee compliance. By exceeding the minimum requirement significant improvements can be made on the carbon emission rate. It is possible to show compliance with Part L just by improving building fabric U-values. However, a combination of improved airtightness, MVHR and modest improvements in building fabric U-values has proved most cost effective in many building developments. Consider reducing U-values for roofs to 0.14, walls to 0.3, floors to 0.2 and glazing to 1.8 but, generally speaking, the lower the better.

4Consider glazing as a percentage of the building floor area:

The regulations assume that glazing coverage is equivalent to 25% of the floor area, which is more than most developments. Where this can be sensibly reduced it will improve the carbon emission rate of the building. If the specification of glazing is also improved the impact is increased. Consider gas filled or triple glazing.

5Go renewable:

The installation of solar thermal hot water systems, heat-pumps

or micro wind-turbines can have a number of major benefits. Often the installation of some of these products can turn an otherwise non-compliant building into a fully compliant one. However, many developers now also see this as the preferred route to meeting other planning requirements or aspirational targets for the use of micro-generation technologies. They can significantly reduce running costs and can be a great selling point. Redring offers one of the most efficient solar thermal hot water systems in the UK - see www.redring.co.uk - and Xpelair has a world-class micro wind-turbine (see www.xpelair.co.uk).

6Improve the lighting plan:

In some buildings the carbon impact of the lighting can be significant and expert advice can assist in demonstrating compliance with Part L.

Modular lighting strategies should be considered. The traditional rules of thumb based on the number of rooms should give way to a recommended number of lighting points by square metre of floor area. It is good practice to install low energy fittings as standard indoors, with consideration given to highly effective control. Externally the regulations require a maximum 150W with automatic switch-off via PIR, photocell and timers.

7Controllability reduces emissions:

It has been shown that easy to use, highly responsive heating systems actually reduce carbon emissions. When heating responds quickly it tends, in practice, to be used more effectively. Where controls are simple to use, people make better use of them. Modern electric heating is highly controllable and responsive. This is recognised within SAP. We offer leading edge electric heating with our Eco-Response technology. Integrated and sensitive thermostats within Creda electric heating products allow precise control room by room, ensuring solar gain is taken into account in maintaining a desired temperature and reducing carbon emissions.

8Background heat:

By ensuring there is a low level background heat throughout the common walkways, like stairwells and landings in apartment blocks, adjoining walls are only considered semi-exposed for calculation purposes, reducing heat losses and improving the carbon emission rate. We offer modern electric heating solutions designed for this purpose.

9Size the cylinder:

The regulations now assume a 170l water cylinder. By ensuring the cylinder is not oversized for its application, heat losses are reduced. If the cylinder size is reduced below 170l then the carbon emission rate is improved. Redring offers cylinders at 90, 125, 150 and 170 litre capacities, as well as larger sizes where necessary. See www.redring.co.uk for a full range of instant water heating products that have no standing losses at all!
