I would like to add that rented accommodation can suffer condensation. a/c dries the air and resolves this issue. My tenants that have had storage heaters installed have commented how much they wish that had a/c

I rent out flats and install air to air systems as standard as they use between 1/3 to 1/4 of electricity compared to storage heaters. They are not on the EPC list of approved appliances - are treated as a non-classified heat source - strong disincentive for Landlords to upgrade rental stock.
