What is the best place to install my boiler? VerifiedThe 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.

Is it useful to switch off my boiler during absence or vacation? VerifiedMany 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? VerifiedYes, 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 difference between a boiler and a gas boiler? VerifiedA 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.
