You need to read the instructions that come with the heater. Heaters draw a lot a current and you need to install it properly or else risk a fire and damage to your electrical system.
You could try and hook up a bicycle workout machine to a battery so when you work out in the morning, you charge the battery. Then put the battery in an electric car.
No, you can charge the battery while it's in the car.
Usually a car battery, but it also depends on the size of the battery.
Jump the car from another car battery or hook a charger to the battery.
Hook positive up first, negative last.
An electric car.
it is an electric heater
Hook it to a battery charger.
You can jack the car up and then remove the electric power steering fan. With it removed, you can access the starter where you can then hook up jumper cables to charge the battery! Such a silly design huh?
Provided the heater is of a low wattage it should not affect normal running of the car
Not enough info. Car heater? House heater? Gas? electric? Water?
battery's?
