I have a studio flat with a new tenant just moved in. With the flat I provide 2 oil-filled electric radiators (as there is no gas so no central heating). The tenant has complained he had to run both the radiators on full for 16 hours to warm up the flat and asked I buy a convection heater to use as well, due to concern for his electricity bill. I find this surprising as I lived in the flat for 3 years and those 2 heaters are more than sufficient to heat that space. The previous tenants informed me they only ever used one of the radiators as the flat heated up so quickly. He was informed before taking on the flat of the heating situation…I have been accommodating and complied with all other things he has requested, but this I feel it is getting too demanding. I’m inclined to say I have provided sufficient means to heat the flat and he will have to buy his own third heater if desired. Wondering what others would do in this situation?
