When buying a large expensive item it’s common place to do your research and you check out all the details of it before buying. You look at the model and what it’s capable of, it’s capacity, what it’s powered by, etc. Whether it’s a house, a car, a boiler, a washer, a computer, or any other expensive item.
Part of my job is to register new boilers and it’s unbelievable how many people do not know what boiler they have. They have gone out and purchased an item that could have cost a couple of thousand pound and they have no idea what model it is. If this wasn’t bad enough, some of them don’t even know when it was installed in their own home, or what powers it!
So a homeowner has paid a complete stranger for an expensive item that they know nothing about, asking said complete stranger to enter their home on a random date, rip out a major appliance that provides heating and hot water, install an appliance they know nothing about or how it works, and they’ve paid several hundred or a couple of thousand pounds for said stranger to do it. Incredible.
