Sun for the solar collectors

If you want solar hot water,you need to keep the snow off your collectors. Lisa did a fine job this morning. You'll notice in the photo that the snow has been piling up copiously on the rooftop. I bought a nice long telescopic pole from SKWEEG (RONA's house brand, I think). Not wanting to scratch the collectors, we use the car brush attachment. It does a fine job, but with anything that freezes to the glass we have to wait for a thaw.

This is the solar controller in the utility room showing the temperature in the solar collector. When this temperature in the collectors gets a set number of degrees higher than the temperature in the water tank, the controller turns on the pump and transports the heated anti-freeze to the coil inside the hot water tank. the reading of 28.7 degrees is good for January! As a matter of fact, the collectors were actively collecting heat when the sun was out today. It's been so cloudy through all of December and January that it's been rare to hear the solar hot water pump going. When the cloud sets in, unfortunately, the collectors do not warm enough to heat the water. Let's hope for sunnier February! The sun starts getting stronger in February, and we could use a break on the hydro bill.
