House won't heat
IT is 0 degrees on this fine, sunny Chicago winter morning. The thermostat
is set for 72 and the house is sitting at 65. The house, built in 1967, is heated with hot water radiant baseboard. Every inch of exterior wall that can have a radiator, has a radiator. I have blown out the accumulated dust/dog hairs of 30 years from the radiators so the air is once more circulating freely. The boiler is busily cycling on and off maintaining a water temperature of 180 degree. I conclude from that, that the problem is at the radiator end. The boiler guy was out in the fall and replaced the expansion tank and air bleeders and bled the system and pronounced it fit 1) WHat is the correct way to fix this? 2) Temporarily, can raising the water temperature to 190 give some relief? How high can I go? Note: there are 4 zones to the system but only 1 thermostat. THe house is equally cool in all zones. I would suspect the wall to wall carpeting (reducing the air flow thru the radiator) but the one room without the carpeting is just as cold as everywhere else. |

This is not a new event. I've been in the house 5 years and it does it every
winter "Duane Bozarth" wrote in message ... Jmagerl wrote: About inadequate heating... 1. Is this a new phenomenon?

The radiators are warm. All the valves are open. I hear no gurgling (air in
the system). I am thinking inadequate radiators but there is no room to add any more. "Noozer" wrote in message news:gsSGd.102855$Xk.73345@pd7tw3no... "Jmagerl" wrote in message ...

Raise water temp to 195, blead each radiator of any air. Is water level
correct, is pump running? Baseboard depending on type, normaly requires higher water temps. |

If the ammount of heat pumped in is less than the ammount leaking out, it is
time to call several insulation companies, and see what they can do to make your house more tight. You can either increase the heat input into the house, or reduce the loss. Reducing the loss is cheaper in the long run. -- Christopher A. Young Learn more about Jesus www.lds.org www.mormons.com "Jmagerl" wrote in message ... The radiators are warm.

A quick check of the baseboard temperature gives around 157 degree. I will
up the boiler to 190. I will admit I have no idea what the insulation situation is other than the ceiling has about a foot of blown in in it. About half of the windows are double pane. All windows have storms. The doors could use some weather stripping but the windows seem tight enough. "m Ransley" wrote in message ... Raise water temp to 195, blead each radiator of any air.

Check that it is operating properly at the burner. Raising the temperature may help if the heater is cycling off and on. If it never shuts off, that means it does not have enough power to heat the house. If cycling, raise the temperature 10 degrees. If not, insulate and/or buy a bigger heater. |

wrote: The boiler is busily cycling on and off Is the circulating pump cycling on and off also? I would think it shouldn't, given that you never reach the set temperature on the themostat. When you say it's 65 in your house, how do you know? Do you check it at the thermostat location? In my house the thermostat is set for 70 (when we're home) but the house never gets up to 70. The reason is simple: The thermostat happens to be in the warmest spot in the house. (smart design, huh?) It is indeed 70 in that spot and the pump and boiler cycle on and off as needed to keep it so. It's more like 66 in my bedroom, which happens to suit my constitution (and wallet). If I wanted it to be 70 I'd have to set the thermostat higher. I guess what I'm saying in my long-winded way is this: Is your thermostat calling for heat all the time? Or is it perhaps in a warm spot, or miscalibrated, or defective, such that it is turning off the heat at a lower temperature than you want? With older thermostats just being physically off level could cause a problem like this. Greg Guarino |

You're supposed to eat more in the winter. Calorie is a measure of heat.

If you are not reaching thermostat set point your pump should be running
continously, is it? |

I've checked the thermostat. Seems to be level. it reads 65 while set to 72.
It calls for heat all the time. THe house seems to be of a uniform temperature (I have thermometers in every room) just low. Raising the water temp got me a few degrees on the air temp. Can I go higher than 190? "Greg G" wrote in message ... On Mon, 17 Jan 2005 10:16:55 -0600, "Jmagerl" wrote: The boiler is busily cycling on and off Is the circulating pump cycling on and off also?

The pump runs continuous but the burner cycles on and off (the water gets to
190). The thermostat may be old (an old honeywell dial type) but seems to be working correctly. "m Ransley" wrote in message ... If you are not reaching thermostat set point your pump should be running continously, is it? |

If the heater is struggling, it may just not have the capacity of the system to do the job. Since it does cycle off, it is able to get the water hot, but you may not have enough radiator surface area. Or you don' t have enough insulation, or you have drafts, etc. Close off the radiators in unused rooms (if you have any) to get more heat to the used ones. Since it will be very cold this week, consider some temporary supplemental heat. It won't take much for a kerosene or propane heater to kick it up another five degrees. Did you post if it saw gas or oil? If oil, the burner may need a cleaning. If the spray nozzle is not right, you don't get the proper heat. If the heat exchanger is sooted up, you don't get the proper heat |

Hi Edwin, hope you are having a nice day On 17-Jan-05 At About 23:41:43, Edwin Pawlowski wrote to All Subject: House won't heat EP From: "Edwin Pawlowski" EP Close off the radiators in unused rooms (if you have any) to get more EP heat to the used ones. This isn't going to make a difference. as long as the burner cycles he is getting all the heat he can. one thing to do is make sure all of the radiators are clean and not plugged with dust. also make sure the space in front of them is open and the carpet isn't too high underneath them causing restricted air flow. -= HvacTech2 =- ...

Your best advice would be to call in a HVAC professional. As messing around with boilers can lead to a catastrophe, if you are not trained to service them. ~kjpro~ |

T... In article , says... The radiators are warm. All the valves are open. I hear no gurgling (air in If your thermostat is a setback type you might try locking it at one temp so the furnace does not have to try and recover from the lower temps in set back mode. I had trouble in single digit temps during very windy day. I turned the boiler temp up to 195 which helped. A house built in 1967 might need more insulation or better windows. Again, his insulation value has nothing to do with it since the boiler cycles on the internal thermostat. ~kjpro~ |

That's fine and dandy to make the home more efficient, but there could be several reasons for the boiler to fail to heat the structure. But damn, you couldn't even answer my test question (about boilers) in the Pro's group...there were many answers that could have been the one...but you failed to reply with ANY of them.

Your system is under pressure and water will not boil at 212. You should
be at apx 12lb cold . I dont know what boiling point is at higher temps but 200 wont hurt the system, call the boiler manufacturer. Did you ever try bleading the radiators yourself? That is your first step. And be sure water level is correct |
#28

It sounds like your radiators are undersized if you bleed each one of
air. More insulation in the attic and better windows and insulating shades and curtains would be your best option. R 60-80 attic+ will help. Cellular shades are R3.3 it will double LowE Argon values. Curtains and liners will also help alot. R35 attic is Minimum code Chicago, Minimum is minimum. |

Oh mg Bubaass water under pressure wont boil at 200 you moron. And Weil
Mc Lain a company youve probably never heard about works as manufacturers instruction at 12 lb cold with radiators 33 ft up , you really should learn about equipment before you post BS . Try instaling a few, My tech instaled it, set it right, just as the old unit was 12lb cold. its obviously not a job for you, you have obviously never worked on a 3 story house 10ft ceilings with full basement 8 ft ceilings. Go hack em in today Bubbaass |

Thats the best you a " pro " can do ? Pathetic. 15lb water boils at
248f, so how will you argue Weil Mclain on that, Weil Mc Lain says 200f water on a 12lb cold system is fine. I suggest you work Quality residential sometime in your 25 yr career to Learn what systems use . You sound too much like Dave of the South, Or Bubbaass , wood stove specialist, trailer specialist. 200 f on 15lb on a HW system is fine, it wont "Junp" as you say. But you are Bubba, the unexperianced , know it all Tard. |
