My boiler will only produce lukewarm water, why is that? Verified

This probably means that the thermostat is broken. Contact the manufacturer for advice.

Is it useful to switch off my boiler during absence or vacation? Verified

Many modern boilers are very energy efficient. During an absence or vacation that lasts 1 week or less it will take more energy to heat the water again than to keep the water at the current temperature. During absences that last longer than 1 week it might save energy to switch off the boiler.

There is water coming from the pressure relief valve, is that normal? Verified

Yes, a boiler is a pressure vessel. When pressure gets too high, the boiler will lower this by releasing water through the pressure relief valve. The installer of the boiler should have attached proper drainage.

What is the best place to install my boiler? Verified

The best place to install the boiler is close to the location where the most warm water will be used (ie: bathroom). This ensures a quick supply of warm water and minimal heat loss.

What is the difference between a boiler and a gas boiler? Verified

A boiler heats the water before you want to use it. A gas boiler heats the water at the moment that it is needed. This means that with a regular boiler, you can run out of warm water when the reservoir is empty.

We bought an AEG hot water tank and a low-pressure faucet, installed according to regulations. When you close the tap, a lot of water runs out after 300ml, first cold and finally warm water

Manual AEG DDLE LCD 18/21/24 Boiler
M. Hage 11-06-2020
Concerns: flow restrictor model DDLE LCD 18/21/24. The manual states that this limiter may not be removed when draining by means of a thermostat, that is clear. At a setting of 24 kW, the white limiter must be replaced by the orange one, that is clear. However, what to do with the limiter at: a) Setting 18 kW, without thermostatic valve? b) 21 kW setting, without thermostatic valve ?
