Do you already have one? If not ACL or Honeywell are the common types. They fit to the cylinder about 1/3 from the bottom by means of a metal band or spring. You must first remove the foam insulation to allow contact. If you are asking about connecting it YM me, and I'll try to advise.

A simple job, but only if you are happy and competent working with electricity.
All DIY shops can sell you a strap on thermostat. The thermostat must be fitted such that the back is touching the metal of the hot water cylinder. If you have a pre-lagged cylinder, you will have to cut a hole in the lagging through to the metal. The thermostat is then placed in the hole and the strap fitted around to hold it in place.
The difficult bit is connecting it to the boiler controls. If you have no cylinder thermostat at present, it is likely that you have a pumped circuit out to your radiators and a seperate pair of pipes to your cylinder that are not on the pumped circuit (a gravity feed circuit). That means that your hot water will be at the temperature you have set your boiler. No problem in the summer as you can set the boiler low. In the winter you set the boiler higher to get the house warm and then the water at the taps is too hot.
In this pipe circuit to the cylinder you will have to cut a new on/off control valve.
You will then have to put interconnecting wires between the new thermostat, the new valve and the boiler controls.
If the system is old, (or newish and installed on the cheap) you may not even have a proper system control, in which case you will need one. That means a lot more wiring.
I suggest you talk to a few friends and you may find one who help you out.
Remember, behind those simple on/off switches around your house is a power that can easily kill you. What might be simple and logical to many is death to others. If this sort of thing is new to you, get a professional to do it. It may cost you more money, but consider the devastation to others if you kill yourself.

Fitting A Thermostat

If the tank is factory lagged, you will have to remove enough of the insulation to allow the thermostat to touch the copper cylinder. If not factory lagged, you just slide a panel of the lagging aside and strap the thermostat to the tank with a band. (kinda like net curtain wire)
Connecting the wiring into your heating system is a whole other thing. I don't recommend you try that bit yourself.
If you buy the thermostat, it should come with fitting instructions.

I am assuming that you are talking about the type of thermometer that is either screwed into the tank or uses a well. In either case it would void the UL listing for the tank and could cause a serious accident. I would not advise even thinking about doing this.
