Volba výkonu
Výkon vodního ohřívače je ve wattech (W) nebo kilowattech (Kw), což se obvykle vztahuje k výkonu elektrické topné trubky v ohřívači vody. Čím větší výkon, tím více času jednotkyTím je zapotřebí více tepla, tím menší doba ohřevu a tím vyšší zatížení drátu.
V roce 2012 byl výkon běžných ohřívačů vody na trhu: 1 000 W, 1 250 W, 1 500 W, 2 000 W, 2 500 W, 3 000 W atd. nastavitelný,1000W/1500W/2500Wnastavitelný,1000W/2000W/3000Wnastavitelný,2000W/3000Wněkolik kombinací např. /5000Ware k dispozicipro uživatele, kteří si mohou vybrat. Když to uživatelé použijí, mohou si vybrat použití jedné topné trubky nebo dvou topných trubek, aby se ohřívali současně podle svých potřeb.

Často kladené otázky
1.U stejného ohřívače vody je množství teplé vody používané v zimě nedostatečné, proč se většina použití elektrických ohřívačů vody akumulačního typu může setkat: Mohu v létě a v zimě umýt rodinu ze tří.
Nejprve musíme pochopit následující teploty:
Teplota vody z vodovodu T1 v létě je asi 20–30 ℃ (přibližně 25), v zimě je přibližně 5–8 ℃ (přibližně 6)
Teplota teplé vody T2pro koupání42℃
TheaveragehotwatertemperatureT3oftheinnertankofthewaterheatercanbesettoaspecificvalue,hereis70℃
Potom se řídíme vzorcem
Vstroj*(T3-T1)*rychlost využití teplé vody
Vteplá voda=70Lhorizontální stroj,míra využití teplé vody0,8Jako příklad,získejte
