I live in an old house that has been turned into 4 apartments. Being an old house with base board heating for your heat source, well needless to say that it can get quite expensive. I have tried many, MANY other types of portable heaters. Though they cut my energy costs by some it just wasn't worth it. After much frustration and much chagrin ( shuh-grin ) I was pretty much going to give up on the space heater thing and just deal with the over priced and under result giving base board heater. My friend came over and told me about the Soleus. I was skeptical at best but the next day he brought over his and let me have it for the weekend. This thing is great! Not only does it let you choose the heat setting, it has a high/low and also and economy setting. The high and low settings obviously speak for itself. The economy setting is a little neat feature. What happens is once the heater has gotten up to the desired temp, and remained there for 15 minutes it shuts down to economy which will let the sensor monitor the temp in the room and will turn the heater back on once it has fallen no more than 2 degrees. No more cold nights for me!
