Rain Collector Heater

[wurzelmac]

Hi all,
these days I added a Davis Rain Collector Heater to my VP2. Snowing the whole day a little and the heater works like a charm. I am very interested how much precipitation it will count this winter. The years before I "only" measured the fallen snow height every day - now I can do both measure the snow and measure the precipitation! 

Cheers,
Reinhard

Reinhard,

I'll be interested to see how much snow water equivalent you get. I made a heater for my VP2 cone, and get similar results to what I measure when melting the snow that falls in my 4" CoCoRaHS gauge.

One suggestion is to apply a coating on the surface of your cone to help moisture run down into the hole. I find that with light snow, much of it evaporates on contact with the cone's surface. I apply Rain-X, a windscreen rain repellant product on the cone, which helps a little.

Hello Steve,

the next days we have an interesting weather - snowfalls are predicted. Today we have had light snowfall (ca. 4 cm) and it shows 1.8 mm of precipitation. Thanks for the suggestion with coating!

Cheers,
Reinhard

Update: In total we have had 17 cm of new snow and that equals to 10.8 mm melted precipitation. At least my VP2 says so.

I also have a heater on my VP Pro.   In addition, I bought a AC thermo sensor that I plug into the AC power that only switches the power on for the heater when the temperature is below about 36=38 degrees.  Saves power and is hopefully extending the life of my weather station and heater.

My plan is to turn on the heater only when snow falls - so it is rather weather than temperature related. But as this is the first winter with this one, I have to do my experiences. 

Cheers,
Reinhard

What brand and model did you get?

Sorry Blick...  I completely missed your question.  I purchased an "EasyHeat Freeze Free "Thermostatically Controlled Device" model EH38
