A motor vehicle cabin heater 10 has first 20 and second 30 liquid to air heat exchangers mounted such that air flows sequentially through the first and second liquid to air heat exchangers and before flowing to a cabin 6 of a motor vehicle 5. The first liquid to air heat exchanger receives a supply of heat exchange liquid from a charge air cooler 81 of an engine charge air cooling system 8 and the second liquid to air heat exchanger receives a supply of heat exchange liquid from a main engine cooling system 9. The first liquid to air heat exchanger provides cabin heating before the second liquid to air heat exchanger and aids warms up of the heat exchange liquid in the main engine cooling system. The first and second heat exchangers may be spaced apart to have a gap between them or may be arranged so that they abut each other.
