Question

How much hot water does the Alde 3020 or Alde 3030 system produce?

Answer

The Alde 3010 and 3020 Compact boilers use a store of 8.4 litres of hot water at >50 °C. The Alde 3030 has a slightly larger 10 litre tank. When mixed at the fixture to a usable 38 °C, this amounts to ˜12 litres of heated water every 30 mins. Cold water <10 °C will take longer to heat.

The Hot Water Boost function cuts out the central heating for 30 mins while another 8.4 litres of hot water is heated to >65 °C. This amounts to ˜15 litres of heated water, mixed. Assuming an average flow rate of 3 litres per minute, this gives ˜5 minutes of continuous heated water for showers.

This can also be used to kill Legionella bacteria if the system has been standing unused for a spell.
(Legionella bacteria dies within 2 mins at 65 °C.)
