Question 2

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.

Question 3

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.

Question 5

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.
