C\u00e2nd am plecat din UK am l\u0103sat eu casa s\u0103 ruleze pe un program economic de \u00eenc\u0103lzire \u00een c\u00e2teva reprize ( 3 ) care adunau 5-6 ore pe zi de \u00eenc\u0103lzire , cu excep\u021bia zilelor de s\u00e2mb\u0103ta, c\u0103 urma s\u0103 ne \u00eentoarcem s\u00e2mb\u0103ta, c\u00e2nd am pus forj\u0103 maxim\u0103, s\u0103 se re\u00eenc\u0103lzeasc\u0103 casa ca s\u0103 g\u0103sim c\u0103ldu\u021b la \u00eentoarcere \u0219i s\u0103 nici nu consum mult. <\/p>\n\n\n\n

Putem sa las termostatul pe 12-15 grade, dar nu voiam s\u0103 m\u0103 \u00eentorc \u00een frig. Puteam s\u0103 las termostatul cum era, dar nu voiam s\u0103 m\u0103 \u00eentorc \u0219i s\u0103 v\u0103rs basculanta cu bani la Scottish Power pe nestat acolo. <\/p>\n\n\n\n

E ok, s-au anulat zborurile, ne-am \u00eentors mar\u021bi \u00een condi\u021biile \u00een care cea mai rece zile din s\u0103pt\u0103m\u00e2n\u0103 era setat\u0103 miercuri.\u00a0 Deci am g\u0103sit casa aproape bocn\u0103 ( 13 grade pentru standarde rom\u00e2ne\u0219ti \u00eenseamn\u0103 bocn\u0103, englejii de abia pun un pulover pe ei )\u00a0 \u0219i nici mare economie nu am f\u0103cut, cu toate cele dou\u0103 s\u0103pt\u0103m\u00e2ni \u0219i un pic lipsite . <\/p>\n\n\n\n

De ce ? <\/p>\n\n\n\n

Acesta este graficul evolu\u021biei c\u0103ldurii \u00een casa aia pe 2 s\u0103pt\u0103m\u00e2ni \u00een care am fost plecat. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Se observ\u0103 c\u0103 temperatura scade c\u00e2nd se opre\u0219te \u00eenc\u0103lzirea la fel de repede precum \u0219i cre\u0219te ? E ca si cum , c\u00e2nd nu mai \u00eenc\u0103lze\u0219ti prin calorifere trece ghea\u021b\u0103. <\/p>\n\n\n\n

Hai, uit\u0103-te mai de aproape. <\/p>\n\n\n\n

Se vede cum creste temperatura c\u00e2nd merge centrala \u0219i cum scade abrupt, p\u00e2n\u0103 c\u00e2nd temperatura se apropie de aia de afar\u0103 c\u00e2nd e oprit\u0103 centrala . <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Temperatura in Reading, \u00een zilele alea a fost de 3-6 grade Celsius. <\/p>\n\n\n\n

Practic , nici nu zici c\u0103 casa asta e \u0219i ea izolat\u0103 \u0219i p\u0103streaz\u0103 \u00een vreun fel c\u0103ldura. <\/p>\n\n\n\n

Dar este. Certificatul energetic atest\u0103 clasa C. Banda mai de jos a clasei “C”, dar totu\u0219i, \u00een \u021bara asta sunt destule case cu eficien\u021ba energetic\u0103 \u00een clasa “E” – m\u0103 rog e greu s\u0103 pui “E” \u0219i eficien\u021ba energetic\u0103 \u00een aceea\u0219i propozi\u021bie. <\/strong><\/p>\n\n\n\n

Nu am f\u0103cut evaluarea energetic\u0103 a casei de la \u021bar\u0103, c\u0103 nu o v\u00e2nd , nici nu o \u00eenchiriez , dar estimez c\u0103 e un pic mai bun\u0103. Nu, nu e “A”, sau avioane gen cas\u0103 pasiv\u0103, nici pe aproape. De-abia dac\u0103 o fi “B”, in cel mai bun caz \u00een banda de sus a clasei “B”. <\/p>\n\n\n\n

Zic asta c\u0103 \u0219tiu eu niste zone cu pierderi de c\u0103ldur\u0103, niste zone unde nu am f\u0103cut ce trebuie, c\u0103 m-am chitrosit, sau nu au f\u0103cut me\u0219terii ce trebuie.\u00a0 Dar aia e. <\/p>\n\n\n\n

\u00centr-una din \u00eenc\u0103perile cu pierderi mai mari este pus termometrul \u0103sta de mai jos. Cea mai rece camer\u0103.\u00a0 Ia uite cum a sc\u0103zut temperatura de c\u00e2nd am plecat eu de acolo \u0219i, evident, nu a mai \u00eenc\u0103lzit nimeni. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Au trecut trei zile \u0219i jum\u0103tate p\u00e2n\u0103 s\u0103 scad\u0103 temperatura de la 20 la 14 grade. Acolo e un glitch cred c\u0103 a mai b\u0103gat tata o sob\u0103 de lemne, s\u0103 \u021bin\u0103 temperatura mai mare c\u0103 zero \u00een instala\u021bie c\u0103 nu prea se uit\u0103 el la termometru, dec\u00e2t \u00een central\u0103. <\/p>\n\n\n\n

In \u00eenc\u0103 4 zile temperatura a sc\u0103zut u\u0219or <\/em>p\u00e2n\u0103 la 9 grade. <\/p>\n\n\n\n

Hai s\u0103 vedem varia\u021bia c\u00e2t locuiam acolo, pentru c\u0103 \u00eenc\u0103lzirea se \u00eent\u00e2mpla tot pe segmente. Ultima oar\u0103 b\u0103gam lemne pe la 8-9:00 seara , apa calda circula p\u00e2n\u0103 pe la 3-4 diminea\u021ba \u0219i mai f\u0103ceam focul a doua zi de diminea\u021b\u0103 ( la 10 c\u0103 nu m\u0103 trezeam mai devreme ) sau mai \u00eencolo dup\u0103 pr\u00e2nz. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Aici am f\u0103cut focul diminea\u021ba la 8 \u0219i am plecat de acas\u0103. Pe urm\u0103 dup\u0103 pr\u00e2nz a mai f\u0103cut tata o tur\u0103 \u0219i a urcat a\u0219a p\u00e2n\u0103 aproape de miezul nop\u021bii \u0219i apoi o ia a\u0219a la vale pre\u021b de aproape dou\u0103 grade \u00een mai mult de 24 de ore, c\u0103 am lucrat \u0219i nu am avut timp \u0219i poft\u0103 \u0219i timp s\u0103 fac focul p\u00e2n\u0103 pe la 16:00 ( deci 16 ore pe dou\u0103 grade coaie ) . <\/p>\n\n\n\n

Sunt dou\u0103 elemente aici, care dau iner\u021bia termic\u0103 a casei. <\/p>\n\n\n\n

Un element este evident izola\u021bia, adic\u0103 c\u00e2t din c\u0103ldura \u00eenmagazinat\u0103 \u00een materialul casei se re\u021bine ( iar asta include terenul de sub ) . Dac\u0103 ai izola\u021bie fantastic\u0103 te ajut\u0103 s\u0103 \u00eenc\u0103lze\u0219ti casa cu pu\u021bin\u0103 energie. <\/p>\n\n\n\n

Totu\u0219i, daca casa ta are o structur\u0103 sub\u021bire \u0219i u\u0219oar\u0103 , chit c\u0103 e foarte bine izolat\u0103, cum sunt casele pe structur\u0103 timber-frame , dac\u0103 ea \u00eenmagazineaz\u0103 pu\u021bin\u0103 energie varia\u021biile de temperatur\u0103 sunt tot rapide ( schimb\u0103rile de faz\u0103) \u0219i ai nevoie de o sursa de incalzirw care s\u0103 mearg\u0103 continuu, sau cvasicontinuu. <\/p>\n\n\n\n

Al doilea element este energia \u00eenmagazinat\u0103 de cas\u0103. Casa de la \u021bar\u0103 are \u0219i pere\u021bi relativ gro\u0219i \u0219i fiind \u00eenc\u0103lzirea prin pardoseala o dat\u0103 ce terenul de sub cas\u0103 se \u00eenc\u0103lze\u0219te ( 2-3 zile ) energia stocat\u0103 e destul de mare \u0219i schimb\u0103rile de faz\u0103 sunt lente \u0219i varia\u021bia temperaturii e lent\u0103. <\/p>\n\n\n\n

\u0218i casa din UK are iner\u021bie termic\u0103 mare , au durat dou\u0103 zile s\u0103 re\u00eenc\u0103lzesc casa de la 13 la 23 de grade; cu centrala la blan\u0103, c\u0103 a dracu’ nu prea f\u0103cea fa\u021b\u0103 la \u00eenc\u0103lziri rapide. Nu peste tot oricum. <\/p>\n\n\n\n

De aici trag dou\u0103 concluzii.<\/p>\n\n\n\n

1) Cas\u0103 de vacan\u021b\u0103 – structur\u0103 u\u0219oar\u0103 cu iner\u021bie termic\u0103 mic\u0103 s\u0103 \u00eenc\u0103lze\u0219ti repede cu pu\u021bin\u0103 energie ( dac\u0103 e bine izolat\u0103) . <\/p>\n\n\n\n

2) Locuin\u021b\u0103 permanent\u0103 structur\u0103 grea ( masiv\u0103 – c\u0103 poate s\u0103 fie lemn \u0219i gross ) c\u0103 dac\u0103 e izolat\u0103 bine rezist\u0103 la \u00eentreruperi de \u00eenc\u0103lzire \/ alimentare cu energie , dac\u0103 e izolat\u0103 bine. <\/p>\n\n\n\n
