Perhaps you will explain the reason for this desire?
If its to save money? Then divide the cost of a therm of gas into the anticipated cost of your project and see how many years it will take to recover your money.
Your boiler may be old but, it works, it may use slightly more gas than a modern boiler but, the figures quoted for modern boilers only apply for a sort period from cold start. Once the house reaches operating temperature the difference disappears.
At the moment, you may well be able to run the taps in several rooms at once, once you change over, you quickly run out of water, have a shower, someone turns on the tap in the kitchen, the shower runs dry.
If you can think of a good reason, then at least keep the same system and just change to a modern boiler. You won't regret it.
