timer if it has a thermostat a constant temperature should be reached although the boiler needs to be insulated

The hotter it is, the greater the heat loss. Best way is to heat it up fully before you need a lot of water, and leave it on for 15-30 mins when you've finished with it, but never leave it off long enough to get completely cold, then it will always recover quickly. Also make sure it's well insulated and adjust the thermostat down a bit so it's not over hot.
ADDED THIS-- Backs up what I suggested...

It is cheaper to have your heating set to come on and off at times to suit you and your family. If the house needs heating up during an off period, you can over-ride this by hitting the 'on' button. Personally, I do not set my heating to come on and go off but simply use the 'on' now button when heat is required. It saves a load of money. Why heat the house when your out?

I emailed the address someone else put up about this a while back, the answer I got was that it doesn't make all that much difference as you'll use roughly the same amount of gas doing either. What they did say was to turn the water heater temperature down by 10 degree and you'll save energy and money that way.

When you go shopping in a supermarket, and you intend to stay for an hour or so, do you leave the engine running , even if there is someone in the car ? I suspect NOT Same rules apply. That is why the combi-type boilers ( instant-heat-up type) boilers were invented. So the answer is NO

Use a modern cover for the cylinder and leave it on.
If you turn it off the water below gets colder and colder and the increasing temperature fall allows a greater transfer of heat from one to the other.
Keeping it on stops the high temperature difference and there- for slows down the overall loss.
Check it out for yourself by using Boyle's law and the co-efficient of heat transfer, 'mu', for the surrounding material. ie The Cyl' Jacket and Copper Cylinder.

cheaper and greener to leave it on all the time, or it has to keep re-heating the water. it is false economy to use timer!

N O you will lose heat always, but have the convenience of constant hot water when you are in a hurry

its cheaper to leave the settings on warm, because if you leave it on a timer then its going to use more gas to warm up, but if you leave it on warm then it will come on for a couple of minutes and turn off.
