Heizwater-buffervat met sanitair warmwaterbereiding WGJ-BN INOX SOLAR

Opbouw en beoogd gebruik

De WGJ-BN INOX SOLAR is een gecombineerd buffervat voor verwarmingswater en sanitair warmwaterbereider met geïntegreerde roestvrijstalen verwarmingsspiraal als warmtewisselaar. Hij is ontworpen voor integratie in centrale verwarmingsinstallaties met verwarmingsketel, warmtepomp of voor het benutten van zonne-energie en maakt zowel de opslag van verwarmingsenergie als de continue verwarming van drinkwater mogelijk.

In het binnenste bevinden zich twee gescheiden verwarmingsspiralen: één van zwart stalen buis voor een aanvullende warmtebron (bijv. zonnecollectoren) en een roestvrijstalen golfbuisspiraal voor de efficiënte verwarming van sanitair warm water, waardoor het apparaat ook als een doorstroomverwarmer werkt. De maximale bedrijfsdruk van het vat bedraagt 0,3 MPa.

Technische kenmerken

De behuizing van het vat bestaat uit zwart staalplaat en is met een 100 mm dikke, dichte polystyreen schuimlaag warmtegeïsoleerd; deze isolatie is verwijderbaar en wordt beschermd door een laminaatomhulling. De roestvrijstalen spiraal garandeert een groot warmteoverdrachtoppervlak en snelle verwarming van het sanitair warm water.

Ter uitbreiding van de functionaliteit kunnen elektrisch verwarmbare patroons van het type EJK 1500 ÷ 9000 van ZUG „ELEKTROMET” worden ingezet. De bouwvorm en afmetingen zijn volgens de specificaties van de fabrikant; aansluitingen en montagepunten dienen te worden uitgevoerd volgens de markeringen op de behuizing.

Veiligheids- en montageaanwijzingen

Het vat mag in gesloten verwarmingsinstallaties alleen in combinatie met een functionerend veiligheidsventiel worden bedreven. Aan de verwarmingswaterretour dient een veiligheidsventiel met een maximale openingsdruk van 0,3 MPa te worden gemonteerd; het ventiel beschermt tegen overmatige drukstijging in het verwarmingscircuit.

Aan de toevoertuit van het koude water naar de roestvrijstalen spiraal en in de zonnecollector toevoer dient elk een veiligheidsventiel met een nominale openingsdruk van 0,67 MPa (6,7 bar) te worden voorzien. Tussen het veiligheidsventiel en het vat mogen geen afsluiters worden geïnstalleerd; de uitlaatopening van het veiligheidsventiel mag niet worden geblokkeerd of verstopt.

Aanbevolen aanvullende componenten

Ter verlenging van de levensduur van het vat en ter waarborging van een storingsvrije werking van het veiligheidsventiel beveelt de fabrikant het gebruik van mechanische filtersystemen (bijv. spoelfilters) aan de koudwatertoevoer direct voor het veiligheidsventiel aan. Deze filters verwijderen vaste verontreinigingen zoals zand, corrosiedeeltjes of slib.

Voor elektrische aanvullende verwarming zijn tijdens de garantieperiode alleen verwarmingspatronen met geïsoleerde verwarmingselementen toegestaan; de EJK-serie van ELEKTROMET voldoet aan deze eis. Alle aanvullende componenten dienen volgens de respectievelijke fabrikantinstructies te worden geïnstalleerd.

Onderhoud en bediening

De functionaliteit van het veiligheidsventiel dient minstens één keer per maand en altijd voor elke ingebruikname na buitengebruikstelling te worden gecontroleerd. Voor elk onderhoud of elke reparatie dienen de respectievelijke systemen te worden uitgeschakeld en volgens de veiligheidsvoorschriften te worden beveiligd.

Reparaties aan het vat en aan de waterinstallatie mogen uitsluitend door vakmensen met de juiste certificeringen worden uitgevoerd. Regelmatige controle en deskundig onderhoud verhogen de bedrijfsveiligheid en levensduur van het apparaat.

Installatie van een verwarmingspatroon

Tijdens de garantieperiode mogen alleen elektrisch verwarmbare patronen met geïsoleerde verwarmingselementen worden gebruikt. Aanbevolen worden de EJK-verwarmingspatronen van ELEKTROMET (type EJK 1500 ÷ 9000). De montage en de elektrische aansluiting dienen overeenkomstig de specificaties van de fabrikant en de geldende normen te worden uitgevoerd.

Toepassingsgebieden en voordelen

De WGJ-BN INOX SOLAR is geschikt voor woon- en bedrijfspanden waarin een combinatie van buffervatopslag voor verwarmingssystemen en vraaggestuurde warmwaterbereiding gewenst is. Bijzonder voordelig is het gebruik in systemen met zonnecollectoren, warmtepompen of conventionele verwarmingsketels.

De combinatie van een groot warmtewisselingsoppervlak, compacte bouwwijze en goede warmte-isolatie maakt snelle warmtelevering en energie-efficiëntie mogelijk. De roestvrijstalen spiraal zorgt voor hygiënische verwarming van het sanitair warm water zonder directe opslag over langere periodes, waardoor legionellarisico's kunnen worden verminderd.

A decent primer -- no more.
Format: Hardcover
This is an odd book for one of America's premier historians. It isn't a bad book -- a person of Bailyn's erudition couldn't write a bad book -- but it doesn't hang together well. The author does not really have anything new to say and a historian of the Early Colonial Period will quickly recognize the usual sources. It is hard to see exactly what historiographical niche this book fills. Even the title is misleading. Sure, Jamestown was barbarous enough by our standards and New Amsterdam was plenty harsh. But, the Bay Colony was, by the rough-and-ready standards of 17th century Europe, pretty civilized. (Compare it with the contemporaneous English Civil War or the Thirty Years War.) As for "Conflict of Civilizations," there was certainly enough of that but the most interesting part of the book, the last third or so on the Bay Colony, is largely an account of Puritan theological quarrels. In fact, one senses that Bailyn felt like he was "home" when he wrote about the Bay Colony. He has, after all, written about New England since 1955 ("Merchants.") He gives the reader a clear account of the theological duels between Winthrop, Cotton, Hooker, Williams, Hutchinson and others. But, others have done this as well or better. Bailyn all but ties himself in a knot to be politically correct toward the Native Americans. For every Indian atrocity he finds a matching atrocity in European civilization. Still, if captured in war one was likely to be a lot better off among the English, French or Dutch than the Pequods. A LOT better off! This volume is part of a series that explores the settling of North America and hardly anyone is better equipped for this than the author. But, what begins as a good account of the horrors of Jamestown drifts into a twice-told tale of the niceties of Puritan disputation. It is almost as if Bailyn got bored half-way through and started channeling Perry Miller. A good book in its way and quite useful for an upper division course or first-year graduate seminar. But, not well-written enough to snare the casual reader and not original enough to snare the professional historian. An odd number.

Sheds Light On A Dimly Perceived Period
Format: Kindle
This book is clearly intended for those of us (non-historians) curious about what is a dimly perceived period of North American colonial history. Living as I do in Tidewater Virginia, I consider myself fairly well versed with the earliest years of English settlement or invasion, depending on your point of view. But, I was wrong. I had, of course, read about the wretched first two years of the Jamestown enterprise, but I had no idea just how ghastly the conditions of the first twenty years of the English colonial period were. Wave after wave of newcomers simply starved or died of disease in those years. The mortality rate was shocking. So many people were dying off that the local Indians did not even think it necessary to kill these newcomers (which proved a mistake, of course). And this was not just at Jamestown. For example, the author says that in any given year in one county 30 to 40% of the children under the age of eight were orphans. And the origins of many of these earliest colonists -- orphans dumped by local churches, beggars snatched off of urban streets, prisoners marched from gaol to waiting ships, many poor people literally kidnapped or tricked into emigrating -- was eye-opening. Talk about the refuse of British society. (As an aside, anyone whose humble immigrant ancestors came to Virginia in those years can forget about doing any genealogical research. You will never find the answers to your questions.) This does tend to be a bleak read. One of the things that jumped out at me was the sad, repetitive tale of European-Indian relations. It mattered not where one was. Virginia, Maryland, Delaware, New Amsterdam, New York, the pattern is always the same. Trade and early friendly relations were quickly undermined by misunderstandings, stupidity, devious tricks, alcohol, and land disputes that led to attack and counter attack and massacres on both sides. One of the things I did enjoy was the Indians' views of Christianity. Those mentioned by the author viewed it as little more than a strange dream. When the concept of a universal god was explained to them they laughed and called it a silly fable. I can only agree. My respect for their powers of reasoning and perspicacity rose immeasurably. Just who was the savage?

Interesting, but a little scattershot (3.75*s)
Format: Paperback
One thing is for certain, in this highly detailed work by the author, there is no attempt to sugarcoat the European experience in emigrating to America in the 17th century. He examines Virginia, the Chesapeake area, New York, and New England. In the initial stages merely surviving was an accomplishment. Most of the early settlers were clueless about overcoming the harsh conditions that they found, not to mention the savagery that the natives unleashed upon them without warning. A large supply of the weak and vulnerable facilitated this peopling of America, despite the dreadful conditions. In addition, as the author shows in great detail, are the conflicts among the settlers. America was settled during a time of great political and religious clashes in England. Most of the settlers were Protestants, but held widely differing, contentious views about religious practice. Much of the governance of the colonies was autocratic, inept, and harsh. A good many of the settlers were indentured by contract for years and thereby were practically slaves, in contrast to the well connected who were granted huge estates. But even then, the author points out that the living standards for even the rich were terrible by European standards. The book is definitely more sociology than historical. One learns about the origins of the settlers across America and the implications for the possibility of robust communities. The author definitely does not hold back on naming thousands of settlers across the colonies; it is difficult to slog through all of that. The book does seem a little scattershot in its organization and subject matter.

UNDERSTANDING THE COLONIAL POPULATING OF THE NEW WORLD. AN ACADEMIC WORK.
Format: Paperback
Pulitzer Prize winning author Bernard Bailyn writing The Barbarous Years opens a sweeping and authoritative discourse into the peopling of North American between 1600 and 1675. From Jamestown, Virginia to Plymouth and the Massachusetts Bay Colony, who were these individuals who braved three plus months voyages on small, crowded and disease infested ships to arrive at the edge of the American wilderness? You will learn not only who they were but why some succeeded while others were destined to fail. images No one needs tout Bailey's credentials as historian and researcher. He is brilliant. However, what is most remarkable is his ability to keep the subject flowing, fascinating and understandable for the lay reader. Bailyn delivers in brilliant digital display the complexity and challenges of the people responsible for the early settlement of North America. Think of this: Why did the Jamestown fail numerous times? Why did the Catholics establish a foothold in Maryland and the Finns and Swedes in Delaware? Why did The Massachusetts Bay Colony begin to work from day one.? Was it religious fervor or the composition of the settlers themselves? What role did the varied Native American tribes play in the success or failure of early settlement. How did the Pilgrims differ from the Puritans and the aforementioned from the Quakers and the Dutch? Were indentured servants a precursor to slavery? Winthrop, Bradford ,Stuyvesant, Keift, Underhill, King Philips War. The Barbarous Years that marked the original settling of America is a most accurate title for the book. Adventurers, scoundrels, orphans, preachers, doctors, lawyers, Native Americans, politicians, merchants and perhaps most important, the hundreds of unnamed families with children who came to America during the Great Migration of the 1630s , bringing with them the skills and the ethic to permanently settle on the land. The " New World" was British North America during its early settlement but Bailyn clearly identifies the complexity of cultures, trade and geography that would eventually become America. The Barbarous Years is a fabulous foundation for understanding colonial America's formative years. Also by Bernard Bailyn: The Ideological Origins of the American Revolution, The Ordeal of Thomas Hutchinson, and Voyages to the West, which won a Pulitzer. A wonderful different perspective of the settlement of the Massachusetts Bay Colony comes from reading Anya Seton's historical novel Winthrop Women. A second suggestion is Philbrick's book Mayflower.

A Sweeping, Memorable Book From One of America's Greatest Historians
Format: Paperback
Bernard Bailyn offered this third volume of his “Peopling of British North America” by looking back at a far earlier period. Instead of looking at the 1760s and 1770s, Bailyn turned his attention to the seventeenth century. Always a fine writer, especially for an academic, Bailyn presented a sweeping look at the founding of Virginia, Maryland, New York, New England and other parts of the Atlantic coast. Bailyn was able to cover a great deal of ground, looking at Native Americans, Swedes, the Dutch and a host of various religious groups from England from the Pilgrims to Catholics. Scholars and general readers alike will profit from this look at the rough, often bloody, birth of America. It is easily one of the most memorable additions to colonial American history in recent years. Highly recommended.
