Question about Heating & Cooling

1 Answer

I have a Honneywell Triple Aquasatat Relay insstalled on by boiler that heats both the baseboard and hot water for my residence. The relay is set so that the low kicks on at 180 degrees and the high kicks off at 195 degrees. I have two questions: First when the low kicks on the temperture guage on the boiler continues to go down to about 175 and when the boiler kicks off at 195 the tempurture continues to creap to about 215. Is my system ok (note that the actual reading on the Relay shows my low at 180 and my high at 190. My hot water is not hot for long during winter operation, how high can I go considering the creap of about 15 degrees after kick off.

The temperatures you mention are reacting in a normal manor. The drop in temperature after it first starts comes from the water being brought back to the boiler from the system. The rise in temperature comes from the residual heat in the chamber after the burner shuts off. I would not push the limits on these settings. Water from the boiler is mainly meant as an assist . You did not answer if you have another hat water heater.

I have a hot water system that uses baseboard heaters with two thermostats. the pump is activated through a Honeywell R845A. Is the R845A the problem?


Using that thermostat on a boiler system requires a relay to be installed. like the Taco sr-501 or an Argo AR-822

My boiler heating is working but hot water is not coming. i want to know how to set hot water 24 hours 7 days


As I understand your question, you have a boiler with a 'summer/winter' hookup for domestic hot water.

Your boiler should run all the time, i.e. not be shut off by you. Your boiler provides hot water for baseboard heat in your home ... possibly through several 'zones' each controlled by an individual thermostat and circulator. Yours may be a steam system. If this is the case, you have radiators not radiant baseboard heaters and no circulators.

Your summer/winter hookup provides a constant supply of domestic hot water. It does this by taking cold water from your water main and passing it through a copper coil which sits inside your boiler and then to your hot water main in your home. Since the coil sits in the hot water at the top of the boiler, it is constantly being heated. This coil may be in a deteriorated condition in your case or it may be too small for your needs.

Several years ago, I did a small upgrade to my mid 1950's era American Standard boiler. The summer winter hookup in my case was mounted on a 4 inch cast iron boiler plug. The coil was 12 feet long (folded up to a package about 1 foot long). I was very afraid when the plumber came in with what amounted to a 10 foot long pipe wrench. My fear was I would have a pile of broken cast iron at the end of the day. All is well that ends well. He got the old one out and replaced it with a coil that consisted of 20 feet of copper tubing 3/4 inch in size (the folded tubing was about 20 inches long and fit nicely into the boiler). We now have all the hot water a household consisting of one guy and three gals would need in all but the extremest of times..

I think you r answer is here ... replace your summer/winter coil with a new, bigger coil.

Something else I did. My kitchen is 60 feet (pipe wise) from the boiler. It takes a long time to get hot water there. I put in a small electric hot water heater just under the kitchen. I put a timer on it so it runs for a couple hours in the morning and a few hours in the afternoon. The hot water line from the boiler serves as the cold water input to the heater. I now enjoy the convenience of quick hot water in the kitchen with the relatively low cost of oil heated water from the boiler as a relatively small cost of electricity.

My winter settings are 160 - 200 and my summer settings are 120 - 150 which seems adequate for our needs.

Thanks for your question at FixYa.com. I hope I have been of assistance to you today.

Hot water not going, wanting to know how to turn it back on?


You have a real good description of your thermostat--
I wonder why you suspect the thermostat to be causing your 'No Hot Water' problem?

First of all, I have to be sure I understand your real problem--
When you say you want to 'turn the Hot Water back on', (It is 'Not going')
Do you mean you want a boiler (maybe in the basement?) -- or maybe a zone valve in a Hot Water, Baseboard heating system-- to be heating your house/ room/ apartment?

I would suppose, if you have the thermostat set higher than the room temperature, that it should be giving a 'call' to the boiler (or Baseboard Hot Water Heater..) to ignite a fire, and heat the waer, and then heat your room, or house.

So-- Could the problem be in the Device heating the Hot Water?

Please tell us more about your heating system-- what type of fuel, -- What happens when you lower the Thermostat, and then raise it-- What used to happen, and what does NOT now happen, etc.

Tell us more clues-- maybe we can help remotely like this-

Furnace firing. Plenty of hot water. No heat.


Most Boiler and zone controlled systems I can remember working on with up to 8 or so zones, the Bell&Gossett circulating supply pumps or pump ran all of the time to keep the upstairs baseboards warm.If you have a relay that controls the pump, see if you can bypass it and if it comes on, replace it. Be sure all of the coils on the zone valves are energized and opening, if it is set up that way.Get back to me and let me know.

Chronotherm Three thermostat vs Buderus Logamatic Computer.


The outdoor thermostat senses the the temp of the outside air, and adjust the boiler water temp according to what it knows is best. The reason that the boiler is running longer is the old boiler used to be constantly sending 180ish degree water to the baseboard, now that water may only be 140ish degrees. The idea behind this is to reduce off cycle heat loss, as the greater the temp difference between the air temp and water temp, the quicker you loss heat. The theory in boiler run time is this, the less times it starts and stops, and the long run times will give you the best efficiency. Hope this answers you questions.

Have an oil fired boiler for baseboard heat and it also has a tankless heater for domestic hot water. No heat being called for only getting hot water for use. Boiler goes to 210 degrees before it knocks...


These boilers usually have multiple controls. The control that would take it out of the circuit at 210 degrees is a safety.

You should definitely have a professional take a look at this unit before you continue using it.

What is the proper way to refill my Hot Water Boiler (Hot water baseboard system) after it has been drained?


your boiler should have a automatic water feeder so it should fill it self , how ever your heating system needs to be purged that means you must let all the air out of the system you usualy do this with a bleed valve on the return line
