How long do the batteries last

Depends what batteries you buy Duracell last over a year

do you need to install this or you can just place it next to the boiler oven etc?

There’s no installation needed. I have just placed mine on a nearby shelf. You can screw it tonthe wall if you want to.

Peace of Mind

Item looks well made and the digital readout is clear. It was very easy to set up, just insert batteries supplied and a loud beep will be heard. The test button works well for peace of mind. Item is quite compact and I have mine sat on my hearth.
