"New" Slantfin Boiler won't heat house above 65 degrees

I htink that he already figured out that he has hot water and not steam based on the "flood" of water that he had in the past.
And, since he has radiators, bleeding them is a good idea -- but he would have to learn how to do that or have someone do it for him
But, I doubt that air in the radiators would cause the short cycling that his heater is doing.
And, just an FYI about steam heat -- they can be one-pipe or a two-pipe steam heat systems.

Hi, You mean it worked like that since new? Or problem just started? Whoever installed it ought to be able to find the cause of trouble. Called boiler support for help?

Nahsani,
A lot of good suggestions and ideas were recently posted about your issue on the alt.home.repair newsgroup. You should check it out.

His ugh, portal, is still down, but maybe he'll be able to see this when it comes up again.
Another reason, it seems, to read the news directly, with a news server and one's own sofware. Then you don't have to worry about a webpage going down, or face the scorn of proper users of Usenet.

Old ones are made of steel and look like scuba diving tanks, newer ones look like propane tanks. There should be an amount of air in that tank, this allows the hot water in the system to expand and contract. Over time, the air pocket shrinks until eventually there is none at all. Then the system will have nowhere to expand and the heat cannot circulate, resulting in the furnace coming on all the time but the house being unable to reach past a certain temperature. It is a simple matter to bleed the tank, replacing the air. Google it. Hope this helps. Joe
