DHP-AX – a flexible heat pump |
DHP-AX – a flexible heat pump with a maximum of efficiency
To meet growing demand on the European market, Danfoss Heat Pumps is launching a new type of air/water heat pump. DHP-AX can be connected to existing heating systems or be expanded to provide a complete heating solution. In other words it is a flexible heat pump that can provide both heating and hot water, and the customer gains a maximum of efficiency at a minimum of cost.
DHP-AX comprises a base unit that includes heat pump functionality. The base unit can be combined with a specially adapted indoor kit creating a complete heating solution that provides both heating and hot water. It can also be connected with an existing heating system or parts of such a system, such as a hot water boiler.
“We have developed this product to meet increased demand on the European market for small, silent and effective air/water heat pumps. DHP-AX is full of technical innovations and we strongly believe it will meet the requirements of a target audience looking for an affordable and reliable heating solution. The flexibility of the heat pump combined with a favourable price and high performance, means the end-user gets value for money,” says Lars Bergen, Marketing Director at Danfoss Heat Pumps.
The product has been developed at Danfoss research and development centre in Sweden. DHP-AX is available in four power outputs (6, 8, 10 and 12 kW) and is being launched all over Europe.
“We see very exciting possibilities for this product. Not least considering the new RES directive adopted by the European parliament, which classifies heat pumps as a renewable source of energy. Combined with the fact that Europe must increase the share of energy produced by renewable sources up to 2020 this opens up major opportunities for the future,” says Lars Bergen.

Increase in energy use in Irish buildings despite economic slowdown
Media Release
14 December 2009
~ SEI Energy in Ireland report revels key trends for 2008 ~
Rising energy use in buildings contributed to an increase of 1.5% in overall energy demand in 2008, despite the economy contracting by 3% over the same period, a new report from Sustainable Energy Ireland (SEI) reveals today.
Energy in Ireland 1990-2008 shows that increased energy for heating as a result of weather patterns in 2008 led to an 8.8% increase in energy use by householders in 2008. This was mirrored by a 7% increase in energy use in the commercial and public services sector, highlighting that the energy efficiency of domestic, commercial and public buildings needs to remain a priority. The enhanced energy efficiency programmes for buildings as provided for in last week’s budget confirm the government’s commitment to this area.
The report also revealed that energy use linked to economic activity declined in 2008 in line with the economic slowdown, with a 5.4% fall in energy use in industry and a first time fall of 1.3% in transport in 2008 mainly due to a decline in freight transport. Imported oil and gas remained the dominant sources of fuel in 2008, accounting for 81% of energy supply. Renewable energy use grew by 21% in 2008, and its contribution to gross electricity consumption was 12%, compared to 9.4% in 2007. This suggests that Ireland is on track to meet the White Paper 2010 target of 15%. Overall, renewable energy represented 4.5% of gross final energy use in 2008 and the estimated amount of avoided CO2 emissions from renewables was one and a half times the emissions from coal burned in Ireland in 2008.
Launching the report, SEI chief executive Professor Owen Lewis said: “Energy in Ireland 1990-2008 is a significant report revealing new insights on what drives Ireland’s energy demand and clearly showing where we need to concentrate our efforts. Improving the energy performance of our buildings remains a key priority and the government’s recent budget support for energy retrofits and upgrades will greatly aid this in 2010 and beyond.”
“The report also demonstrates the clear effects of the economic crisis of 2008. The key issue now is what will happen when we come out of this recession? It is critical that the return to economic growth is not matched by a corresponding growth in energy demand. The two must be fundamentally decoupled so that Ireland’s future economic successes are not undermined by unsustainable energy use.”
“As a nation, as individual businesses and as householders, we must continue to make sustainable energy a normal way of life and to aggressively pursue technologies and practices that thrust Ireland into the forefront of the clean, green revolution.” |
The New Cylinder Range
Available from June 2009, Grant Ireland’s striking new collection of contemporary cylinders has created quite a ripple within the heating industry.
This comprehensive range includes upgraded twin-coil cylinders with sizes ranging between 200 and 400 litres and introducing a triple-coil cylinder in 300 litre.
Grant Twin Coil Options
The Twin Coil range of mains pressure hot water cylinders were developed to meet the growing demand for systems that combine a renewable heat source with a standard oil, gas or electric boiler. They are particularly suitable for use with solar hot water systems like Grant Solar Thermal. When correctly matched and installed this arrangement can significantly reduce the dependence on traditional fossil fuels resulting in lower energy bills.
Grant Triple Coil Options
The Grant Triple Coil is a cylinder unlike any on the market at present. The model is a further development of the Twin Coil cylinder range and available in a 300 litre vented or unvented arrangement. Triple Coil cylinders are designed to combine different heating technologies within a single system by utilising up to three separate high performance heating coils and one 3kW immersion heaters. When installed as a ‘vented’ cylinder, it is possible to combine a solid fuel or wood burning appliance with an oil or gas boiler, alongside solar thermal.
Superior Quality and Design
These extremely efficient cylinders are unusual in their design, with every unit being manufactured from the highest specification 1mm thick duplex stainless steel. The casings are also injected with 40mm of CFC/HCFC free, fire retardant polyurethane foam. These innovative manufacturing processes achieve surprisingly low standing heat losses, ensuring outstanding efficiency and reliability. Grant cylinders are constructed with high efficiency internal coils using 22mm corrugated stainless steel tube, giving maximum heat transfer, high efficiency and quick recovery. Additionally featuring 22mm compression fittings, labeled and colour-coded tappings and a 25 year guarantee on the cylinder shell, this competitive range altogether offers exceptional quality, value for money, as well as peace of mind. |

Many people wish for a white Christmas each year, but this year Danfoss will do its utmost to make sure that Christmas will be a little greener than usual in terms of energy consumption. The company is launching an online advent calendar where visitors to the website can win prizes by answering questions on energy-efficient heating solutions.

And it makes good sense to put energy efficiency on the agenda at Christmas. CO2-emissions and global warming might put a definitive end to a white Christmas in large parts of Europe in years to come. And this would also mean a definitive goodbye to snowmen, sleighing and other traditional family entertainment during the winter months. But solutions to the problem actually already exist.
”When it comes to the heating of homes, already today we have a series of energy-efficient solutions. We can cut down considerably on CO2 emissions if we install them on a broader scale. Of course, we don’t expect that more radiator thermostats or advanced room thermostats will end up under the Christmas trees this year because of this advent calendar, but we do expect to increase awareness of the solutions we already have at hand to reduce CO2-emissions”, says Bjorn Sejr Nielsen, Marketing Director at Danfoss Randall.
And the savings potential in the cold winter months is considerable, both when it comes to the environment and to heating bills; for instance by installing new radiator thermostats or chrono-proportional room thermostats. Precisely how much there is to save, you can find out by opening the advent calendar.
Every day from December 1st and until Christmas Eve, visitors to the Danfoss website will have the chance to win some great prizes, such as hampers, games consoles, wine, iPods, digital cameras, camcorders and supermarket vouchers. Entry is straightforward and free and all answers can to be found somewhere on the website.
Correctly answered entries will be put into a random draw and a winner will be picked for each day. Winners will be notified by e-mail and prizes will be sent immediately
