1. 1 1 THE NEW GENERATION OF NIBE GROUND SOURCE HEAT PUMPS The principle behind ground source heating is basically very simple but at NIBE we have developed the technology over the years leading to increasingly User convenience You need never run out of hot water again Equipped with a high output heating coil and a 180 litre tank any of our heat pumps which feature an integrated water heater now give you even more efficient water heating and rapid replenishment of hot water supplies You can save even more energy by scheduling your heat pump to provide for the varying energy needs of your household on a daily weekly or longer term basis What s more our new heat pumps are so quiet you can hardly hear them User friendliness Our new generation of heat pumps have an intuitive interface which benefits both the end user and the installer For example an automatically activated guide leads you through the set up process quickly and correctly There is a help function where you can turn for more information about each function and an alarm which high lights problems and suggests how to solve them An easily removed compressor module and a clearly organised in ternal design facilitate installation and service The inclusion of USB ports make software updates and operating data downloads quick and simple to perform Multi purpose With the addition of various accessories our new heat pumps can do much more than merely heat2. t b a TS i 2 P a WM a c 7 En n M Pa s gm Pu 4 v sae 1 5 we me ee Jm Ju Mea NIBE OF SWEDEN Living in harmony with nature The Swedes have a long and impressive track record of clever money saving innovations that use resources sparingly The sim ple reason for this is that Sweden was historically a poor agrar ian country A harsh winter climate made food scarce for many months necessitating careful forward planning Today Sweden is a technologically advanced country with a successful economy so this is no longer necessary However the mindset continues to be manifested in the form of fabulous cost saving innovations NIBE is a perfect example of the economical Swedish mind at work The company was founded by Nils Bernerup in 1952 after a par ticularly cold winter And over the last 60 years it has become Swe den s leading supplier of domestic heating products continually driving the development of ever more efficient heating methods Early products included water heaters and pressure vessels In the 1970s these were supplemented by electric boilers Later heat pumps and a wide range of other heating products that meet the needs of the European markets were added to the mix Nowadays NIBE is a leading player in heating solutions around Europe which is partly due to the fact that our hea

11. OUND SOURCE 30 The background The Nilsson family home in Bjuv is a single storey house with a cellar with a total surface area of 230 square metres It was constructed in 1976 and like many Swedish homes built during this period it was equipped with an electrical boiler and water based radiators When the old boiler went on the blink the Nilssons decided to look for a more cost effective modern heating system based on a sustainable energy supply Reliability and user friendliness were also key criteria in their search Solution They decided to invest in the NIBE F1245 8 ground source heat pump which not only met all their key criteria but would reduce their heating bills dramatically The NIBE F1245 8 requires very little space and the ground probe 160 deep in this case can be drilled on the smallest of plots The Nilssons also chose a NIBE UKV accumula tor tank in order to increase the amount of hot water in their heating system and to achieve a better more even heat production Results Since they made the switch from an electrical heating system to a NIBE ground source heat pump the Nilsson family s annual energy consumption has gone down from 33 000 kWh to 10 000 kWh This means they save 23 000 kWh each year In financial terms enough to give the whole family an extra holiday if that s what they feel like doing The heat pumps colour display gives them all the information they need at a glance and thanks to its intuiti

32. we see a significant reduction in CO emissions Meanwhile the prices of traditional energy sources are rising steadily with the result that more and more people feel inclined to consider alternative more efficient energy sources Now their customers have started demanding a solution builders architects and property developers can no longer ignore the need to employ alternative technologies that make better use of the world s energy resources START WITH A HEAT PUMP Heating your house with a heat pump is the proven best option for the environment There are a number of reasons for this One obvious factor is that a heat pump does not use any combus tion process or other energy to generate heat It simply extracts the heat that already exists in the air ground or water source and puts it to use to heat your home This means lower emissions Secondly in comparison with other heating systems the amount of electricity needed is relatively low That s because electricity is not the main energy source it s only needed to run the heat pump and enable the heat extraction process While the exact energy saving varies according to what you benchmark against it generally meas ures between 6096 and 8096 Another interesting point to consider is that heat pumps like every manufactured item contains what we call embedded energy That is the energy required to make the product and transport it from the factory to the site where i
