i've no hot water in the kitchen. Why would i need it? I take a shower in the nearby toilet/shower room which has the hot water. For coffee/tea i use an electric kettle to boil the water.
I must have lived in 12 different flats in Hong Kong, and never had hot running water in the kitchen in any of them. I defrost my frozen chapatis by pouring boiling water over them from the kettle. I would guess the OP is living in luxury and doesn't realise it.
Place we're looking at is about 24 years old but newly renovated after last tenants moved out. Seems like many expats live there too. So I don't consider it to be too old not to have hot water in kitchen.
Anyway, Landlord has agreed to lower rent to have heater installed in kitchen.
You can just install a small water heater under the sink. Easily done.
