Kana mumwe munhu apedza kugeza odzima mvura, chibatiso chekudziya chemhangura chiri mukati me tankless unit chichiri kupenya chichipisa ku150 kusvika 260 madhigirii celsius (300 kusvika 500 degrees Fahrenheit) uku homwe diki yemvura inogara yakamira mukati memakoiri emhangura. 2. Iyo yakavharirwa hafu-lita yemvura inotora kupisa kwesimbi kwasara kubva muchinjanisa kupisa, kunosvika 65 kusvika 75 degrees Celsius (150 kusvika 167 degrees Fahrenheit). 3. Kana mumwe munhu abatidza pombi yekugezera 30 kusvika 90 masekonzi gare gare, vanotanga vawana mvura yemupombi inodziya, ichiteverwa nekamwe kamwe 3-sekondi slug ye70°C (158°F) mvura inopisa zvikuru inosundirwa kunze kwemuchinjiziri wekupisa, ichiteverwa nekukasira nekuputika kwemvura inotonhora apo burner ichibatidzazve. 4. Maitirwo ekubvisa kuputika kusina tanki: Tarisa chiratidziro chedhijitari pamberi pechidzitiro chemvura chisina tank uye ita shuwa kuti yekuseta yedhijitari yakakiyiwa ku 49 madhigirii Celsius (120 madhigirii Fahrenheit), bvisa chinopisa chekupisa gore negore nekutenderera **15 malita (4 magaloni) echikafu-giredhi revhiniga vhiniga (masevhisi chena mukati mesevhisi 4 maminetsi akarembera mukati metangi yakavharirwa maminetsi mashanu. inopfuura inokonzera kubikira kwenzvimbo uye kugogodza kwemhepo), uye kuisa diki ** 2- kusvika 8-liter (0.5- kusvika 2-gallon) tangi yebhafa kana nzvimbo-yekushandisa ASSE 1070 thermostatic mixing valve ** pasi pemasingi anoshandiswa nevana.

Mibvunzo inowanzo bvunzwa¶

Ndeipi yakanyanya kuchengetedzeka tembiricha yekudziisa mvura yemumba kana tiine vana vadiki kana nhengo dzemhuri dzakura?¶

Sangano reU.S. Consumer Product Safety Commission (CPSC), American Burn Association, neDhipatimendi reMagetsi vanokurudzira kuisa mathermostats emvura ekugara kusvika ku49 degrees Celsius (120 degrees Fahrenheit), iyo inoenderana ne "Low-Medium," "Warm-Hot," kana triangle reference mark pane dzakawanda gasi mvura inopisa dials. Kana uchigara nevacheche, vana vadiki vari pasi pemakore mashanu, vakura vanopfuura makore makumi matanhatu nemashanu, kana chero munhu ane chirwere cheshuga/neuropathy kana kuderera kwekufamba, isa poindi-yekushandisa ASSE 1070 thermostatic mixing valves kana kuseta mvura inotenderera inomira inomira zvekuti tembiricha yemvura inobuda mubhavhu neshower spout haigone kudarika 43 kusvika 406 kusvika 406 degrees celsius (1111 degrees Celsius).

Sei pombi yangu yemvura inopisa yakangoerekana yakosora mweya nemhepo pandakaibatidza mangwanani ano?¶

Kana pombi yemvura inopisa ichipfapfaidza, kuputika, nekupfira homwe dzine chisimba dzechitsinga nemvura iri kufashaira chinhu chekutanga mangwanani mushure mekugara isina kushandiswa husiku, hita yako yakatadza kudzima mukati mehusiku uye yakapisa mvura iri pamusoro petangi kupfuura 100 degrees Celsius (212 degrees Fahrenheit). Panguva iyo mapombi akavharwa, iyo 350 kusvika 550 kilopascals (50 kusvika 80 PSI) yekumanikidzwa kwemvura yemunisiparati mukati mepombi yako yepombi yakachengetedza iyo mvura inopisa kubva pakuvira kuita gasi (nekuti mvura iri pasi pe60 PSI inovira pa153 ° C / 307 ° F pachinzvimbo che100 ° C / 212 ° F); pakarepo pawakavhura pombi uye kudonhedza kudzvanywa kumhepo (0 PSI), mvura yaipisa zvikuru yakapenya pakarepo mumhepo mukati mepombi spout. Dzima chinopisa chinopisa chemvura kana vharafu yegasi nekukurumidza.

Kana hita yangu yemvura ichipisa uye vharafu yebhurosi yeTPR padivi iri kudonha mvura inopisa, ndinogona kuvhara pombi kuti imise kubuda?¶

USAFANIRA chivharo, puragi, kubvisa, kana kupeta vharuvhu yebindu-hose papombi yekuburitsa yeTemperature and Pressure Relief (TPR) vharafu pahita yemvura kana bhaira. Ivhavha yeTPR ndiyo chete yemagetsi inokundikana-yakachengeteka kudzivirira kupisa kwemvura inopisa kubva pakuputika munjodzi yekuputika kwemhepo (BLEVE) iyo inogona kuunza tangi yesimbi ye50-gallon yakananga kuburikidza nenyaya mbiri dzeimba; kana TPR vharafu iri kubudisa mvura inopisa kana mhute, iri kushingaira kuponesa hupenyu hwako nokuti mvura inopisa thermostat yakundikana mukutiza kana kuti tangi yako yekuwedzera inopisa yazara nemvura.

Ini ndinoyera sei tembiricha yangu yepombi chaiyo kumba kana heater yangu yemvura ichifona ichingoti "Kudziya / Kupisa / A / B / C"?¶

Nekuti madhiri anotenderera pamagetsi emvura inopisa ("Yakaderera / Inopisa / A / B / C / Yakanyanya Kupisa") inozivikanwa zvisina kujeka uye inogona kusiyana negumi madhigirii Celsius (18 madhigirii Fahrenheit) kubva patembiricha yemvura chaiyo, nzira chete chaiyo yekuseta hita yako yemvura iri papombi yekubikira. Batidza pombi yemvura inopisa mukicheni pakuyerera kwakazara kwemaminetsi matatu kusvikira tembiricha yadzikama, bata tembiricha yekubika nyama yekubikira kana thermometer yesiwiti mukati merukova rwunoyerera (kana mukati memugedhi iri kuramba ichifashukira nerukova), uye gadzirisa dhiyabhorosi yako yemvura nechinoche chimwe pamaawa matatu ega ega kusvikira tembiricha yacho yadzika madhigirii 409 celsius.
