I've moved into a house where the primary hot water supply is a gas
boiler and hot water tank. However, there is also an ensuite in the
attic that is supplied by an Ariston Classico unvented electric
immersion heater (model STD 125). The tank has 2 immersion heaters,
one at the bottom and one at the top and according to the manual, the
bottom one is for night time and the top one for a day time top up. I
understand this is typically for use with Economy 7 tariff. Each
immersion heater is wired to a separate mains switch.
The previous owner told us that in order to get hot water we should
turn on both immersion heaters for a few hours. This all works fine,
however, it is not that convenient to turn the water on an off
manually each day. Is it advisable to put a timer switch that will
turn on both heaters for a couple of hours each morning? Or separate
timer switches for the two heaters?
Any advice on a simple setup would be much appreciated. btw, we're
not on economy 7.
Thanks and regards,
