Yes but run the vent tube outside
A licensed electrician can install a heater for you. I would look in your local yellow pages for a licensed electrician to install the heater and any other electrical work you may have.
Yes install it on the cold water line as close to the heater as possible.
You have a major electrical problem.. If a breaker trips more than once you need to leave it off and call an electrican.
When selecting the ideal location for installing a new water softener, it is best to install it near the water heater in your home that you will find the easiest place to tie the new unit into the existing plumbing system. The ideal location, near the water heater is typically in the utility room, garage, or basement of your home. Remember that your water softening system will also need to be within easy access range of both an electrical receptacle capable of handing the manufacturer specified amperage, and a utility sink or floor drain.
The clicking noise you are hearing could be the heater is overloading the breaker and it is on the verge of tripping This could be caused by the heater being to large for the circuit. Check the amperage rating on the heater and the rating on the breaker It also cold be the circuit breaker is going bad and needs to be replaced by a qualified electrician These are 2 possible answers you also could have a bad (loose) electrical connection some where in the circuit
One can purchase a utility heater from many general hardware stores, such as B&Q. Alternatively, one can buy a utility heater from webpage stores such as Amazon or Ebay.
A block heater does not use a fuse on the vehicle It is like a heating element on an electric kettle , it has a circuit breaker or fuse on the electrical supply panel in the building ( or if it is a plug in post in a parking lot , the breaker is inside the post )
Would be best not to ... especially if both, when turned on, will exceed the amperage rating of the breaker to which they are connected.
Assuming you are referring to a 240 volt residential hot water heater you will need to install 10/2 NM cable (Romex) with ground from the service panel to the water heater wired to a 30 amp circuit breaker in the service panel. If you cannot see the water heater from the service panel you will need to install a service disconnect at the water heater.
I think you need to do some checking, A GAS water heater does not normally need electrical service that large- an ELECTRIC water heater will. So- just what do you have- gas or electric?
try higher amp breaker
You can pull the front panel off the Hot Water tank and there is a red reset button on the electrical that controls the power to the elements. Or, try resetting the breaker on the electrical panel serving the tank.
