Total Home Environment’s heat pump ventilation system has con- tributed to a new eco home where heating bills have been elimi- nated. The low energy require- ments have been achieved through a combination of passive solar design, high levels of insula- tion and by storing excess solar energy produced during the sum- mer in an interseasonal thermal store. The total heat loss for Tony’s house in October was 100W and an average of only 700W in February, six times less than an average home. Tony comments: “It is not possible to buy a boiler or heating system to cater for energy losses that small, the Genvex is all I need.” The Genvex Premium 2’s counter-current heat exchanger retains the vast majority of the heat in the expelled stale air and further heat is occasionally supplied to the air by the heat pump.

Warm your home this winter with a contemporary woodburning stove from Vesta Stoves.
Their range has been developed using simple design principles, whilst including the very latest com- bustion technology.
Each stove contains Vesta’s revolu- tionary trademark airblade system, which preheats the combustion air and delivers a blade of air across the glass pane.
This not only helps to raise the effi- ciency but also ensures no soot/ condensation settles on the glass.
All stoves carry a two year anti- corrosion and structural no-non- sense warranty.
Enecsys Limited has received Italian and Spanish certification for its products from Bureau Veritas Consumer Products Services, Germany, GmbH. The micro inverters comply with the Italian “Guide for connections to ENEL Distribution electricity network” and with the corresponding Spanish legislation for connecting photo- voltaic installations to the low volt- age network. This certification enables Enecsys to sell its long-life micro inverters into residential and commercial solar PV markets in Italy and Spain. Enecsys micro inverters mount on the rails behind solar modules and accept DC input from either one or two mod- ules, depending on the model of micro inverter. Uniquely, Enecsys micro inverters come with a 20- year limited warranty that is appli- cable over an ambient temperature range of -40 to +85 °C.
