quite curious abt storage water heater
it requires preheating prior to bath
and let's say we have a 20L storage heater
a low-flow shower head can emit 3-4L of water per min. if the hot water to cold water mix ratio is 1:3, so in 1 min, 1L of hot water will be exhausted. Hence a 20L storage heater can last continuously for only 20min? let's lower the shower head pressure to 2L per min, then we can prolong the storage heater capacity to 40min?
i do enjoy long, hot bath, easily half an hr, to wash away the fatigue.. haha
what if the hot water stored in heater is insufficient? need to stop bathing and walk to kitchen to switch on the heater again (if u've earlier switch it off to conserve energy)
anyone to clear my doubts
