In order to prevent boiler from rusting (oxidation of magnetite layer) we must have to preserve the boiler with reducing chemicals like hydrazine hydrate.

Add water to the boiler. You should have an automatic pressure reducing water make up valve, somewhere near the boiler. If it feeds directly into the boiler, make sure the boiler is cool when you add. Normal pressure on a cool boiler should be around 12 psi. The pressure will rise as the water is heated. You need a minimum of 1/2 psi for every foot of rise in the loop. So 12 psi in the basement will allow most systems to have a rise of appx 24 feet to the highest strip of baseboard. Remember, the pressure relief valve on the boiler lifts at 30 psi, so you need to stay well below that when the boiler is up to temperature.

The price of a natural gas boiler will depend on a few factors. For example, the company that is selling the boiler, the quality of the boiler and where one is located. Prices may vary depending on location and availability.

In the combo boiler for the central heating? You need a small piece of hose (or it might have a permanent connection) to fix to the mains from the boiler. Then turn the taps near the boiler for the mains and the boiler. You want the pressure to be about 1.3 bar
In order to determine what size boiler you need, you will need to have a Manual J Load Calculation performed on your home.

Not sure i used to no though....
Hi. No, these are not the same thing. A Combi-boiler can be a type of condensing boiler that does not need a tank and just heats the water on demand. A combi boiler can be of a condenisng type - in other words there are combi boilers that are condensing boilers. However, there are many types of condensing boiler that do have a holding tank, so not all condensing boilers are combi-boilers. By the way, if you are looking into a combi boiler, make sure that your installer has factored in your likely hot water usage and that this type of system will supply you what you need even at peak times.
"Firstly you need to make sure you've got the right size boiler cover, as boilers do come in all shapes and sizes. Then empty the boiler and cover it. Then slowly refill it."
Yes you can bleed a combi boiler. You do just the same as with a conventional boiler. However, the pressure will drop in your system, so you simply need to adjust it using the little tap (usually below the boiler) to bring it back again (Usually aronud 1.5)
