The demand for Dimplex Renewables hots up

“In spite of what was an undeniably tough period for the building services industry, the past 12 months has seen the demand for renewable technologies here at Dimplex Renewables, continue to go from strength to strength.”

With over 1000 Dimplex heat pumps already installed across the UK and hundreds more properties already benefiting from Dimplex solar, demand for renewable technologies is being driven ever higher by the sustainable agenda across all sectors of the market.

head on in 2010

As these trends continue, 2010 is going to be a time of challenge and opportunity with:

• Changes to Building Regulations Part L, SAP and the Code for Sustainable Homes all taking place.

• The challenges laid down to the commercial sector by the Carbon Reduction Commitment.

• Wholesale changes to the way microgeneration and renewable heating systems are funded via the new Feed in Tariffs and the Renewable Heat Incentive

At Dimplex Renewables we’re rising to meet these challenges. We’ve doubled our dedicated renewables sales and marketing resources and have teams focused on the needs of specialist market sectors such as social housing, schools and commercial applications (see the story on the back page for more). Our product portfolio continues to expand too, with the introduction of a new range of MCS-approved air source heat pumps offering market-leading levels of performance. Then there’s our new SmartRad range of intelligent, fan-convector radiators, which are specifically designed to work with heat pump systems. Plus we’re also expanding into other technology

including solar PV, something we’ll have more news about very soon. So,

Here’s to a successful, energy saving year to us all!

Meeting the challenge of change

Now there’s less fog on the Tyne

A stunning new development of 85 high specification riverside apartments located on the southern bank of the River Tyne, Gateshead, is being provided with energy efficient heating from a communal system of nine Dimplex 28kW air to water heat pumps.

The innovative solution was specified, designed and installed by Dimplex heat pump installer-partner Azure Natural Energy Systems and was completed in late 2009. Each flat has underfloor heating installed with individual time/temperature control and is designed to run at low temperatures in order to maximise the efficiency of the heat pump system. Heat meters log the energy usage from each flat and can be remotely read and billed, ensuring each flat owner only pays for the energy they use.

Matthew Evans, owner of Azure explains “We looked at all the alternative renewable heating systems available, including ground source heat pumps, water to water heat pumps (using the river Tyne), biomass and solar thermal combinations. The most cost-effective alternative was a communal air source heat pump system to deliver heating to the building with domestic hot water served by individual, electrically heated cylinders.”

Communal heat pump systems are growing in popularity for multi-occupancy buildings such as flats, student accommodation and nursing homes. They are a cost-effective means of achieving Code for Sustainable Homes ratings and meeting minimum renewables planning requirements.

Developers such as McCarthy & Stone and a number of housing associations have also successfully installed similar schemes using Dimplex high capacity heat pumps, with some schemes also opting to use Dimplex high temperature models to provide domestic hot water as well as heating.

SAP Appendix Q

A new scheme in SAP, called Appendix Q, has been launched to allow the true performance capability of heat pumps to benefit carbon emission calculations in new dwellings.

In a newly designed online database, individual manufacturer’s product performance details replace the default settings for the seasonal efficiency – and resultant CO2

emissions – of the

LOW CARBON HEAT FOR ALL WITH NEW DIMPLEX LAB M HEAT PUMPS

Dimplex is making low carbon heat available to all with the launch of a new range of domestic air source heat pumps. The LAB M range provides efficient heating and hot water for the modern home, yet is competitively-priced and designed to keep installation costs low.

And with the forthcoming revised Building Regulations Part L, the introduction in 2011 of the Renewable Heat Incentive and the progression of the Code for Sustainable Homes, air source heat pumps present a major opportunity to reduce carbon emissions from domestic heating and hot water.

With compact dimensions the LAB M is ideal for the smaller property footprints typical of UK housing, particularly for social housing but also for new build, with today’s dwelling density targets.

Available in a choice of 7, 9 and 11kW outputs, the LAB M range is designed to provide both heating and domestic hot water, operating at outside temperatures as low as minus 15°C. Weather compensated flow temperature control ensures system efficiency is maximised year round.

Single phase electricity supply with soft start control makes the range suitable for domestic use, while minimal maintenance and no annual safety inspection gives peace of mind for landlords. The units are ideal for installation in off-gas areas and come with a three-year warranty when installed and commissioned by a Dimplex approved installer.

The range is currently undergoing approval under the Microgeneration Certification Scheme (MCS), which will give eligibility for grant funding under the Low Carbon Buildings Programme.

system. A new tool developed by the BRE enables manufacturer’s certified heat pump performance data at a range of standard operating conditions (heat source and water heating temperatures) to be modelled against individual building characteristics in SAP and provides an accurate, building specific, heat pump seasonal performance factor for heating and domestic hot water. The overall system efficiency is then converted into CO2

emissions for inclusion within the SAP Dwelling Emission Rate calculation.

The scheme will benefit heat pumps which are able to demonstrate high levels of efficiency across a wide range of operating conditions, and allow specifiers to benefit from the resultant CO2

savings within SAP.

Dimplex high temperature ground source heat pumps (SI MEH range) are included and further Dimplex heat pumps, such as the new LAB M series, will be added shortly.
