Radiant Ceiling Heat: Energy Usage Explained

Radiant ceiling heat supplies heat through radiant heat transfer. Radiant heat panels offer more energy saving than traditional electric heaters or heat pumps. Radiant heat can be the main source of heating or can be a supplementary heating source for certain areas.

Energy Savings

Ceiling mounted radiant heat panels are heated with electricity or a system of tubes of hot water. Most home panels are electrically heated. These panels have a fast response time when turned on. This can result in energy savings because the room can be heat only when it is occupied. They can heat up to 150 degrees Fahrenheit in 4 to 5 minutes. These panels don’t heat the air like other heating systems. Instead they heat the occupants of the room directly. So if the panels are positioned correctly then the heat will be used economically and provide energy savings over air forced heating systems that heat the entire home.


Radiant ceiling panels are usually made of fiberglass insulation board with a heating element. They are typically 1-inch thick and come in sizes from 1’x2’ to 4’x8’. They use 120 volt or 240 volt electrical connections. They heat up to 170°F.

Pros and Cons of a Diaphragm Hot Water System

Whenever you are working with a diaphragm hot water system, it is important to know both the pros and the cons of it. This is something that can help you to make good decisions about whether or not it is for you.


These systems tend to have large tanks, which mean that they can supply hot water to more outlets at the same time. The thermostat that comes along with it will also help you be able to keep the desired temperature all of the time. It is also very rare that you will find yourself having to deal with frozen pipes.


You can expect to have a high energy bill because of the nonstop heating of the water. The energy is more than likely going to become wasted if you are unable to use the water in large quantities. Standby heat loss is something else that you will have to worry about unless your tank is very well insulated.


Basically, it all comes down to how much water you will be using and how much you are worried about your energy bill. If you have a lot of people who live in your home, then these tanks are a good idea.
