Hi Phil, hi Lannette
Here is some information from some of my US students who have kindly shared with me what they use to heat their rooms. Lannette I am sure I emailed you some of this info already.
One person uses a Holmes Infrared Quartz heater (feels like a hot lamp but not enough to heat the room to proper hot yoga temps). So he ordered a Vornado electric heater which is supposed to be very powerful and is capable of 105 plus degrees to use in conjunction with the other. He also uses a Honeywell Quick Steam Humidifier which is digital and gets to as high as 65%. It should be turned on a while before class depending on the ambient humidity.
Another uses a Kenwood and a Holmes electric oil filled heater. Both 1500W and both state cut out thermostats of 95F. However ‘waterwatch’ says temp reaches over 100F. Waterwatch also runs the appliances on different circuits where possible. This is actually information that she shared on another thread.
And here’s my 2c worth: make sure that you have excellent insulation. If your floor is non-carpeted then you may find it takes longer to heat the space and it may be harder to hold the heat in there. Take a look at what is on your windows. Maybe stick up a layer of plastic (that vinyl kind of stuff they use for restaurant awnings) and this will markedly change the ability to retain heat in the room. Our first home studio we heavily insulated in the roof just over that room and it worked beautifully.
Although the heater you use is important the insulation and the way you treat the hard surfaces can make or break your ability to reach the right temperature. In that first studio we had a heater that was supposed to get to temp but never did till we covered the cold floor and also lined the window.
I hope there are others out there who can chime in with other brand names that work for them.
