I have an Albion unvented direct unit. After 1 shower in the morning the water gets cold. At night the 'off-peak' light is on, which means the timer program is working. Now I have had to program it on 'boost' mode for the whole day...which is not economical and might damage the heater. I've change the thermostat of the lower immersion but problem persists.
Anyone can advise on what's the problem? Thanks!
