Hi ,
Your back boiler will disconnected and a condensed boiler will be fitted. You can use your existing heating system but be sure that a powerflush is done when you get it installed.

A back boiler is a boiler which supplies a central heating and hot water system and is fitted into the recess of a fireplace.
A boiler works by heating water in an enclosed space. The expansion of water molecules as it transforms from a liquid state into a gaseous one causes the boiler to generate a vast amount of pressure. This is generally the science behind a back boiler.
when our heating system was changed from a back boiler to a wall mounted one we had the back boiler removed so as to revert to a 1st class chimney, so we could have a coal fire if required, and the flue liner was taken out.
Vaporization is the rapid change of water into steam, esp. in a boiler.
*A boiler check valve is usually made by Watts and called a Watts 9D. This prevents the water that goes into the boiler backflowing and having the heating water from the boiler coming back into the domestic water and having you drink it or shower in it.* Cheers,QuiteSomething

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)
YOU DON'T the ASME /NBBI codes have certain requirements regarding boiler manufacturing and a high pressure boiler can cause severe damage if it is not properly designed and routine maintenance performed ....
The feed check valve of a boiler is on the line coming out of the boiler it is usually to prevent the water from going back in to the boiler its coming out of so it would build up excessive amounts of pressure which will cause the t&p valve to blow temperature and pressure
