Because of my work I often visit houses and take a photo of the boiler. Almost every house has one yet the boiler has a mysterious existence; sometimes hidden away in a cupboard, sometimes displayed in a kitchen or bathroom.
They are almost all white, metal, and box like and yet are still unique in their situation, offering a small insight into the house I've been in. This is a homage to the boiler. Thank you boiler for heating our water.
