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

[Tony Hwang]

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?

[Tony Hwang]

Hi, OP, have you talked to Slant/fin tech support. Was it installed by authorized dealer? Official authorized dealer at least will have a factory trained tech.

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

Radiators hot, so it is heating up. I removed cover on mechanical thermostat & turned middle lever counter clockwise to extend sensor
