hey guys,
Question here..
plan to run my Oil heat tonite [ Hot water Baseboards] as temps in the basement are mid 40's, it 's all going to drop more and although I don't anticipate low 30's in the basement, want to be cautious about all my pipes down there but we Do get heat loss pretty soon in this Not well Insulated house so I don't want to exclusivly use the Oil Furnace all night. I want to use both the Stove and the oil heat.

what would I set my wall thermo at and what would I put stove on also? just need the Oil Furnace to kick on here/there thru the night. with help from the stove to keep it from getting too Oil Thirsty...
[I know if I took a few minutes to think about it I would know what to do but getting Generator ready, scraping some ice I like to hear from anyone who actually does this frequently.
 
Do you have a programmable tstat for the oil burner? If so, whether it utilizes morning, day and evening or just set-times, adjust the t-stat to call for heat, but only for a short time by then setting the next time to well below where it close the circuit. This way you don't have to worry about setting temps, but rather set it up to turn it on 2 or 3 times over the night. If that made sense. Haha

thanks but just the Honywell Analog on the wall..
Since having a pellet stove, never have to run the furnace But, That is a god way to handle this if I ever buy a programable down the road..
 
Set the thermostat just below the current temp at thermostat location, then drop the stove one heat level. Better to run the oil multiple times o/n vs risk frozen pipes.
 
Before I installed my ThermGuard, I would run the boiler by turning up the thermostat to 85 for 10-20 minutes when I got up in the morning, when I got home after work, and just before bed. My pipes go thru the unheated garage, so those were the ones I worried about. Of course you have to remember to turn it back down (set a timer or something). Since I installed the ThermGuard, I have it set to go off 3 times a day for 10 minutes. Haven't had any issues (KOW)

Just something to think about for the future, although it doesn't help you right now.
 
If your really concerned about it just run your oil heat at night on cold nights. Oil is still pretty cheap. Your talking about dollars difference compared to pellets not 10s of dollars.

It's best not to set up two thermostats in automatic if you can help it. The two systems will work against each other.

What Ranger72 suggests is decent, as it's like running your oil furnace in stove mode. If you can get a thermostat to give you enough time settings, it might work. But when the oil heat kicks it, it will cause your Harman to throttle down if you are in room temp mode.

I run my PC45 in stove mode, and set it where it puts out a decent amount of heat but not enough to keep the house at the temp I want. My furnace is on a thermostat, so when the house cools a bit, the furnace kicks on and heats up the house every hour or so. That gets me some heat in my basement.
 
With this cold and the cheap oil prices, we have been running both. Have the pellet stove set at 72 and the furnace at 70. It runs about 4 times a day

was checking the thermGuard out last year around the polar vortex time but forgot about it when the weather changed..lol was not quite sure if the thermGuard Interfears with furnace needing to come on for DHW when your heat/Hot water are from same unit.

yeah.. can always do that. just thought with a stove I could cut the runtimes a bit..
as I said, our house cools down pretty quick so furnace will cycle a lot during a cold night and remind me WHY I got a Pellet stove in the 1st place...:oops:
Thankfully we have a Split system.. thermostats on both floors...
plan on using the 2nd floor one tonite but wanted to calm down the 1st floor one for next few nites.

Put your stove on the manual setting to keep a maintenance burn and will run when needed and set your boiler and stove the same. That may offset each other

yes.. thought about that ...
with a Harman was advised to Not USE room temp since probe and furnace will mess with each other. Hot water baseboards on both sides of our stove..
Stove temp for sure..

Yes, depending on where your thermostats are located, and where each dumps heat, this is correct. Two automatic systems will fight against each other. One should be in a pure run mode (like your pellet stove), which is stove temp.

I have been doing this for three years during deep cold snaps with good results
 
I have also been running both, set the pellet stove high enough so it runs 24/7, then set oil heat to kick on when needed, usually only once per day, maybe twice on super cold days.

My basement has its own thermostat so no issues there, although it is still in the mid 50's down there with no heat on, it is set at 51 degrees.
 
Turn stove off if u want to. Oil still cheap and good to use your furnace which is your primary heat anyway.

Or be cheap and worry about your pipes freezing.
 
Been running my propane furnace the last couple days, was worried about pipes freezing as well. Kind of enjoying having all the rooms, including the rooms far from the pellet stove, nice and warm.
 
I've been running my oil furnace for about a week now. The price of oil is equal to pellets at this point. Really enjoying the uniform temperature throughout the house.

I have 2 circuits for my boiler and when renovating we had removed the baseboards in the living room (where the stove is located) and kitchen (electric radiant floor heat). So in essence I'm using the boiler to hear the two opposite ends of the house, and it has really helped with heat distribution.

The Thermguard does not interfere with normal operations of the boiler, just will turn it on at set times (actually at set intervals), then turn it off after the set amount of time - but not if your thermostat/DHW it calling for it.
