Solar Thermal Hot Water System Dimplex solar hot water packages combine all the key components into easy-to-install kits for a typical three and four bedroom home. As hot water needs change during the homeowners lifetime, our systems are designed to react to fluctuations ensuring needs are always met. Have confidence knowing that every component has been carefully built for quality, suitability and reliability. Why choose a Dimplex System? Super Value: Designed to be the highest performance-to-cost system. Engineered Glycol Protection: Dimplex collectors limit the collector stagnation temperature to under 35 F/55 C protecting the glycol from overheating which can degrade heat transfer fluid and cause it to become acidic and corrosive. Highly Efficient: Blue titanium absorber surface coating sets the standard for premium collectors. Single Wall and Double Wall Systems available, depending on your local plumbing code requirements.

Tips for a Professional Installation Before installing the solar thermal system visit our web site at www.renewables.dimplex.com for a complete installation guide. Collector Placement: The proposed location must have access to southern sky with a minimum amount of shading between 0:00 AM and 3:00 PM each day throughout the year. Aesthetic impact on the property should be considered. Consider the remaining life span of the roof shingles prior to installation. Collectors mounted closer to the peak are easier to install by providing increased attic access. Collectors should be located as close to the solar storage tank as possible to minimize heat loss in pipe runs. Solar Tank Installation: Ensure you have allocated enough space for the solar storage tank installation (near the customer s back-up hot water source). The tank measures 63 ¼ high x ¾ diameter. Ensure the household s main supply of potable water is supplied in accordance to the North American Plumbing Code and Standards. Pumping Stations & Controls: Ensure sufficient wall space for pumping stations, expansion tanks and controller approximately x 4 wall space for single-wall systems, 4 x 4 wall space for double-wall systems. Close proximity to 0 volt supply. 3

How Does it Work? The first step is to determine if the local plumbing codes require a Single Wall or Double Wall System. 4 5 3 How Does a Single-Wall System Work? () The sun heats the solar fluid in the collectors () This solar fluid, a mixture of polypropylene glycol and water, for freeze protection, is pumped (3) and circulated through the in-tank heat exchanger (4). The solar controller has a sensor in the collector and the solar storage tank that activate the circulation pump when there is sufficient solar energy to be delivered. During times when there is little or no sun, a back-up heating system utilizing the customer s back-up tank (5) activates to provide adequate hot water. How Does a Double-Wall System Work? The Double Wall System consists of the same key components as the single wall with the addition of Dimplex s innovative modular HX-A pumping station with a second heat exchanger.. 4
