Hello all. First time poster with a Hardy H2. I am looking for options on remote temperature monitoring. All I wasn't too do is have the ability to monitor high/low temp at the OWB. In the event of low temp such as fire out, or high temp because of a stuck flapper or door open. I have looked at the digital readout that RSI sells as well as a wireless BBQ monitor. Abby and all suggestions welcome.

I have the BBQ monitor and love it.  The alarms work great and warn of both the events you discussed.  And it is really cheap.

Muffin, thanks for the input. Are you using the single prob model or dual prob?

Muffin, thanks for the input. Are you using the single prob model or dual prob?

Dual probe.  One on supply and one on return.  The return is fun to watch and does tell you something about your system efficiency.  With nothing calling for heat, it should be close to the supply.

Ordered the Maverick ET732. Should be here in a few days.

can you tell me how they work, i see there are 2 probes and 2 monitors, 1 small 1 bigger.
i'm about 225 ft from house to owf.  thanks

I have the ET-73 model. I have used it for 3 years now with great results. My remote probes are not out at the boiler but rather on each side of the heat exchanger so that I can monitor what the temp is before it goes through the hx and after it goes through. The temp on the incoming side is about 1 degree below the temps at the boiler with my set up. I don't see any reason to place it actually out at the boiler.

[Grjfer]

The reason I want it at the OWB is to monitor high/low temp conditions. Not sure placing it at the heat exchanger would give me enough warning time of a boil over or fire out condition.

Unless your lines between house and owf lose a lot of temp. Shouldn't be but a few degrees difference.

can you guys tell me where the probes go, i'm assuming you just strap them to somewhere convient on supply or return lines.  does it matter copper or pex.

[Sluggo]

Your going to get a much better reading off from a metal pipe as opposed to Pex.  Put it where it's convenient and simply compensate for heat loss on any alarms you set.  Say if your probe reads 165 entering the house but your stove is at 175 then just set your alarm 10 degrees off.

I also use the maveric et-73. It works well. To get the most accurate reading with the probe located on pex I have placed a layer of foil tape on the pex the length of the probe then a layer of foil tape over the probe. The foil helps to conduct the heat into the probe by increasing the surface area for heat transfer. After the foil tape I use split pipe insulation and then wrap the whole area with foil backed insulation..it appears bulky but works well for me.
