Anyone with any heating issue to give me feedback, low-skill

I am looking for a participant for my GCSE research project, who has experienced any issue with their heating, regardless of whether it is in the present or the past. You will not have to do much work. You will have about 2 hours of low intensity and low skill work. This will be done across 4 months.

This work entails mainly giving me feedback on products that I show you and also, describing your heating issue. Technical expertise is not required, but you should be honest and able to share your experience.
