You can but it will need to be a plastic or acrylic heater, inline heater, or have a heater guard over it, otherwise it may melt the acrylic. For smaller tanks small mini heaters are available that would work just fine. Check out www.bigalsonline.com they will have what you need.
Before using a heater, how about you check with either the manufacturers or the place you got it from if it is safe to do so.
Not sure what you are asking here, broke as in not working? or broke as in pieces of glass are in the tank? If the heater is not working, you need to purchase a new heater. If the glass tube is cracked or broken and pieces of glass are in your tank, then you need to unplug the heater and remove the glass from the tank.
No, the heat will melt the plastic. it is hard to clean up, and is harmful to your hermies.
So the tank is grounded.
does not need to be removed
No, gravel covering the ground of the tank or bowl will do fine. If you can fit them, they might also like an aquarium plant (living or plastic).
If I understand the question, you would need a plumber to run a gas line for Natural gas (or setup a propane tank). If you used an electric heater, they would need to get some more electric to the existing box (another 220 circuit). You would also need a concrete pad put in the ground to support the heater. Ideally, this would be part of your installation process, just make sure you get any necessary inspections for new gas or electric lines.
It all depends on how much the tank holds and the wattage of your heater I like to have 10 wattage for ever gallon so if you hVe a ten gallon tan you need a 100 watt heater also the temperature of you want will make a deference normally my 20 gallon tank can go from 46F to about 77 F in two hours
According to DIY on Hot Water Promblems if theres not enough water then you hit the reset button. If the water is too hot then change the temperature and reset. If you have a leaky heater then you need to replace the valve. If you have a rusty tank then you need to replace the water heater. If you have a noisy heater then you need to drain and flush the tank. If you have dirty water then drain and flush the tank and do it on a regular basis.
I have just done that, you need the complete filler neck off the donor car with the plastic tank as the pipe is shorter that feeds the plastic tank... swap your sender unit over as the plug for the wiring is a different connection , the metal tank has a bolt in sender unit and the plastic one is held in with a screw on collar but they fit no problem...then you need to plug the breather hole in the plastic tank with a 5mm bolt as you will now use the breather pipe on your original sender unit which goes to the filter box at the very back of the car... you will need to make 2 new straps to hold the tank up as the original plastic tank straps arent long enough..lastly make sure you take the heat shields off the plastic tank donor car and put these on your car.
