very little hot water

Hi, i have a pulsa coil 2000, 140l. From the off-peak i can have a shower first thing in the morning, sometimes 2 depending on how quick you shower. I am then left with no hot water for the rest of the day, maybe a luke warm tap at best. I can boost and that gives me some hot water for another shower or two.

Both thermostats are set to MAX.
Green light is not on the front of the boiler but this may be the bulb.
Red light on circuit board is flasing twice, normal
It does seem to heat water just not very much!

Should i receive hot water in the evening after only using the off-peak heater.

Thanks in advance.

Once heated if the unit is a small one you will run out of hot water.
In the evening you will need to boost.
I take it the unit is on off peak 24 hours a day 7 days a week?

Most likely because your unit is a smaller unit, you would have to use the boost supply in the evening.
