# What are hydronic convectors?

## What are hydronic convectors?

Hydronic heating convectors use hot water or steam from a separate boiler to heat a water-to-air heat exchanger coil mounted in the heating convector unit. A thermostat or manual switch operates a fan to blow room air across the heat exchanger coil to deliver heat where it is wanted.

What is the difference between a radiator and a convector?

The difference between radiators and convector lies in the convective heat which only the latter type of units generates. Radiators give off radiant heat, whereas convectors deliver convective heat. In this process, the convector heats up air particles, which then rise, cool down and ultimately end up descending again.

### How do you size a cabinet unit heater?

Start with the surface area – Measure the height, width, and depth of your enclosure. Find the Surface Area by: Surface Area = 2(length*width + length*height + width*height). Find the temperature differential – By First figuring out the lowest temperature your cabinet will experience where it is located (ambient temp).

How do hydronic unit heaters work?

Hydronic unit heaters utilize non-potable hot water or steam produced by a boiler, indirect water heater or other means. Hot water runs through a finned coil while a blower or propeller fan forces the ambient air through it.

## How do fan convectors work?

Fan convectors are a type of heat emitter. Unlike a conventional radiator, fan convectors heat the air that flows through the unit before circulating the warm air into the room to bring the space up to temperature. Once the water temperature within the fan convector reaches 29ºC, it begins to operate.

How do convectors work?

How Does a Convection Heater Work? Tapping into a natural phenomenon known as “convection,” air inside a convector is heated becoming less dense than the surrounding cool air, enabling it to rise due to buoyancy. As the heated air rises, the cooler air on the floor is drawn into the convector, creating a constant flow.

### Should radiators be called convectors?

Which type of radiator is most efficient?

The best material for a modern radiator is aluminium. As we previously mentioned, Aluminium is better for heat transfer which makes Aluminium radiators incredibly efficient. They’re also very stylish right now and would look great in many rooms in the home.

## Does a cabinet unit heater have a fan?

The components and sequence of operation are fairly simple. The main components in a hot water unit heater include a fan, a valve, and of course the piping and coils along with the cabinet.

Do cabinet unit heaters have filters?

Quick-change permanent filters are removable without tools. Cleanable filters are standard. Sound dampening insulation on all front panels. Blower platform, blower, and blower motor on all sizes are removable as a single unit.

### Is hydronic heating cheap to run?

Hydronic heating systems are less expensive to run than some other types of heaters. By some calculations, hydronic heating systems are 35 percent more cost effective than running a ducted system. \$1295 for reverse cycle air conditioning (2 Star) or \$835 for a 5 Star system. \$1045 to \$1255 for hydronic heating.

Can hydronic heating be used to cool?

While hydronic systems tend to be associated with heating, it’s an often-overlooked fact that hydronic technology can also provide extremely comfortable and efficient cooling. Just as water is effective at conducting heat, so too can it effectively convey cooling.

## What types of Sterling convectors are available?

Designed for maximum flexibility of installation arrangement, Sterling Convectors are available in free-standing, semi-recessed, wall-hung and fully recessed models. Enclosures are formed from heavy-gauge steel, and finished in a prime coat suitable for field painting, or in any of the decorator colors on the Sterling Color Chart.

What is a sterling conveyor?

Sterling Convectors are engineered for both forced hot water and two-pipe steam heating system installation with heating elements of lightweight non-ferrous construction.

### What is Sterling’s product based on?

Sterling’s product is based on the Frenger design. Frenger radiant ceiling panel systems were the first to be certified and tested in Europe over 40 years ago. Sterling’s product has been installed in hundreds of installations throughout the United States and Canada.
