ERH Design Guide
1. Number of Units Required
The first consideration is whether the units are to be installed indoors or outdoors.
Indoor areas are well protected from the environment and have a lower heating demand compared to outdoor areas. Therefore each unit will cover a larger area of floor space.
Outdoor areas on the other hand will always have some exposure to the environment. Hence, each unit will cover less floor space. As a rule of thumb we recommend one heater for every 25 square feet of space to determine the amount of units required. For every foot higher you mount the heaters, you need approximately 40% more heaters.
2. Mounting Height
ERH Panels should be mounted roughly between 7.5' to 8.5' above the ground. It is best to permit a higher mounting level only in a well protected / enclosed area. In order to bring the ERH Panels down from a high ceiling, wall/ceiling brackets, tube or chain suspension mounts will be required. The Wall/Ceiling mount brackets are available in various sizes while the chain and tube suspension come in lengths of 35" long and can be tailored to each job by cutting to a required length on site.
It is important to note that the higher the units, the greater quantity of panels required. Similarly the lower the units, fewer panels may be required.
3. Configuration of Units
Once the number of units required is known, the configuration must be designed. There are three configurations from which to find a solution for almost any area. Note: you may need to add extra units to enable appropriate spacing or ensure aesthetic appeal. It is better to add, if necessary, not cut out units.
4. Surround Heating
This is the best configuration possible for small to medium areas. For an installation where you might not want to heat the whole space, instead a space within an outdoor area like a seating area or dining area, surround heating is optimal; i.e. for a dining area, this configuration ensures all individuals in a seating area receive heat from the back from the unit behind and also from the unit on the opposite end of the table. All units using surround heating should be tilted 12.5 degrees toward the center of the table.
5. Parallel Configuration
This configuration is particularly well suited to long narrow areas such as balconies and verandas or larger areas. The optimal design is to have the heaters parallel with each other to help overlap the heat creating a warm, ambient environment. The panels should be spaced 3" to 4' apart and 4" to 31" end to end.
6. Line Series Configuration
When it is not possible to do surround heating or parallel configuration, it may be possible to do a line series or for projects implementing the wall mount bracket. The panels should be spaced 4" to 31" end to end.
