Q. What does SunnyTherm® do?
A. SunnyTherm®  heats the air in homes, offices, workshops, greenhouses, etc.

Q. How does it work?
A. It circulates the air through a series of panels that absorb heat from the  sun, and returns the heated air into the living space.

Q. Can I store heat for use at night?
A. Yes. It is simple to build your own heat bank to store the heat for use at night.

Q. Do I need an electrician to install it?
A. No. The standard model simply plugs into any convenient electrical outlet to power the blower. You can even use a small photovoltaic panel to operate it entirely off- grid or when the power goes out.

Q. Do I need a plumber to hook up water pipes?
A. No. There are no pipes and no water involved.

Q. Do I have to mount it on the roof?
A. No. It can be mounted on any exterior wall with good exposure to direct sunlight.  Mounting it on a wall also  prevents snow buildup in the winter.

Q. How often does it require servicing?
A. The only moving part is the blower, which is design  rated at 50,000 hours. Even if it is operating 8 hours every day, it would take more than 17 years to reach 50,000 hours.

Q. What effect do clouds have on performance?
A. The more sunlight it receives the more heat it provides. But the SunnyTherm®  will still provide heat when there are occasional clouds or even with a light overcast.

Q. Can I install SunnyTherm®  myself?
A.Yes. SunnyTherm®  is simple enough for a Do-It-Yourselfer or any local handy man to install easily.

Q. Can I turn the system off?
A. Yes. Just set the thermostat to your desired temperature and it will turn on and off automatically.
