Wilo’s Gary Wheatley explains why changes are in store to ensure the energy sapping pump is more efficient... Iwill go away soon, the arrival of new legislation requirements of the current A-rated pumps.From August 2015, the EEI limit value will bepresent will then become superfluous, because asa rule, pumps will be better than the minimumn the middle of a difficult economic phase,when a lot of people are keeping their headsdown and hoping the current difficult times via Europe, that has to be complied with can reduced to 0.23.

And it starts on January 1. (integrated pumps). Although a pumping revolution sounds a bit In the last implementation stage, the grand, it’s every bit as important as that regulations starting from 2020 will also apply to statement sounds.

In order to achieve this goal set by the The energy efficiency classes specified at enquiry number 173 NIBE launches ground source heat pump for larger installs The NIBE F1345 is one of a new generation of heat pumps, designed to supply heating and tap water needs in a cost efficient, environmentally friendly way. With its two large scroll compressors, the NIBE F1345 is said to be the ideal ground source heat pump for large residential and commercial installations and other buildings with a large heat demand. The intelligent system controls both compressors as necessary to give better power control, less wear and greater operational ability. It is more flexible than ever and with its advanced control system, it can be adapted to several system solutions. In systems with up to nine heat pumps and with a wide range of accessories e.g. for control of oil, gas, pellet-fired or electric boilers, you find the full flexibility for your installation. The NIBE F1345 is equipped with a multicolour display, user friendly controls and upgradable software via the built in USB port. It is is manufactured in four sizes: 24, 30, 40 and 60kW. Comprising two heat pump modules and a CPU unit with a display to control the heat pump and additional heating, the NIBE F1345 has built-in circulation pumps, making it easy to connect to the heating medium and brine circuits. The energy from the heat source is taken up via a closed collector system in which a mixture of water and antifreeze circulates. enquiry number 174 88 OCTOBER 2012 HEATING & PLUMBING MONTHLY
