Guys, we are talking about the same thing. I was pointing out that there is no need for an expansion tank and a gravity feed/expansion tank so get rid of one or the other.

The water feed i was talking about drops mains down to 1bar and is adjustable. Add an approved check valve and you won't lose your boiler water if the mains go down. Every boiler system in North america works this way. Use a proper sized exp tank and you can keep the water oxygen free for years so your rads will last a long time and there will be no need to bleed rads every year as some people need to do.
