BBoilerBooiilleerr Total System Efficiency SSolarSoollaarr Solar Integration with a Hydronic Boiler Integrating a condensing boiler with solar hot water heating provides the great efficiency advantages of 95%+ combined hydronics with renewable energy in one lean package which is a far superior solution to tankless or conventional hot water heaters.
Single Tank Systems: Save Space and $ A single tank systems employ a storage tank with two hot water heat exchanger coils, the solar one in the bottom of the tank and the indirect fired coil in the upper portion of the tank. These tanks are designed for thermal isolation of the top and bottom portion of the tank. This system is very popular in OG300 Performance Europe because it saves both space and the additional cost of Certified Systems a separate tank. 92% Efficient Appliance Water Heating • Space Heating and Solar Hot Water Single Tank Sizing The single tank Boiler Solar System saves space and installation costs using a single tank for solar and Because only one of the storage tank can be counted upon for conventional hot water. gas fired water heating storage, care should be taken in sizing the system. For example, a 119 galloon tank will have 60 gal- lons of gas fired storage available, so care should be taken in estimating the peak hot water loads for the building, with spe- cial attention to whirlpool baths. Generally speaking, homes with more than 3 bathrooms should employ a two tank sys- tem design.
Two Tank High Capacity Systems Two tank Boiler/Indirect systems work very much like a con- ventional solar system with a gas fired water heater backup, except that the gas fired portion of the system is far more eff- cient. These systems provide both extra solar and gas fired storage for high capacity systems used in large homes. This system can also use the Storage+ control and piping strategy to further expand solar utilization. OG300 Performance Certified Systems See Solar StoragePlus System on the next page. 92% Efficient Water Heating Space Heating plus Solar Hot Water The dual tank Boiler Solar System provides more solar storage for high capacity hot water systems.

The Way Its Been Solar hot water systems usually deliver solar hot water to a conventional water heater only when there is domestic hot water demand. If there is no domestic demand a conventional gas fired water heater is usually turning on and off due to standby losses and recirculation pump losses, even while hot solar water can be readily avail- able. Extra Solar Storage: StoragePlus Reduced Stagnation Time. Using the conventional water heater for auxil- iary storage reduces system stagnation time and virtually eliminates the use of auxiliary heat dur- ing most months of the year. When the solar tank has reached operating limit during the day, More Solar, Less Gas or Electricity a second circulator pulls solar hot water into the gas water heater, keeping the solar system oper- ating at acceptable temperatures. StoragePlus Increase Total System Efficiency By using the conventional water heater for auxiliary solar storage, the use of gas or elec- tricity is significantly reduced by reducing standby and recirculation losses and adding more solar energy for domestic hot water How It Works: STS systems use Taco Smarts The STS control/pump module uses the Taco VT variable speed solar control. This control not only increases solar collection effectiveness by 20% but also has the ability to switch on a secondary circulator when the solar tank reaches operating limit, pumping solar hot water into the gas water heater, sensing the temperature in the conventional water heater and turning off the secondary circulator when the operating limit is satisfied or solar energy is no longer available. Conventional Tank Hot Water Heater or Tankless? The SolarPlus System results in far less firing of the convention water heater thus gas/electric tank inefficiency is far less relevant economically. A tankless is more efficient than a standard tank but is far more costly. A tankless is much more likely to need de- liming and general servicing than a conventional water heater. Conventional water heaters accommodate hot water recirculation systems most effectively.

Active Systems or Passive Systems Active solar systems are those that employ a circulator and solar control to actively circulate water through the solar collector(s). Passive Systems are those without a circulator/control that rely on natural thermosyphon of heat from a tank or direct heating of a tank on the roof (batch heating). STS provides active systems because they are typically more efficient, more esthetically attractive, and can store solar energy more efficiently.
Freeze Protection Many thousands of solar systems where lost to freezing collectors and water corrosion in the 1980s’. This is why we recommend only systems that are isolated from potable water and have positive freeze protection.
Closed Loop/ Glycol: STS Preferred Systems These systems use a heat exchanger to isolate domestic hot water from the solar collectors. They use anti freeze within the solar loop to pro- vide the best positive freeze protection. This type of system also reduces system corrosion for a long system service life.
Drainback Drainback systems are designed to drain the water in the system from the solar collector(s) so there is no fluid to freeze in the collectors. These are very effective systems when adding additional solar surface area to a system for space heating or other applications. The pipes must be slanted correctly to assure draining the collectors.
Open Loop These solar systems circulate potable water directly through the solar collectors. Due to freeze problems and corrosion in the past, STS does not recommend the use of these systems in California/Nevada.

Single Tank and Two Tank System Design A single tank design, which is very popular in Europe, stores both the solar and conventional hot water in a single tank with special thermal traps. These systems save both equipment costs, space and offer the advantage of incorporating very high efficiency gas fired conventional systems sim- ply and effectively. Single tank systems, with reduced storage for gas fired hot water, will meet their capacity with roughly three bathrooms or about 4,000 sq ft. Consult us for hot water demand sizing. Two tank designs are useful for large homes with very large hot water demands or when a client wants a larger solar space heating participation with a Phoenix Solar system.

CLOSED LOOP INSTALLATION KITS Each STS Installation Kit includes our pre-plumbed modules with the circulator, control, pressure relief valve, check valve, temp/pressure gauge, purge valves, expansion tank and expansion tank connection and tempering valve. Anti freeze fluid must be purchased separately.
Drainback Installation Kits Each drainback system will require a drain- back tank, a bronze or stainless steel circu- lator and a solar control, in addition to the solar tank and collector(s). The Taco VT series integrated pump/control is a good choice for drainback systems because they use less energy. Drainback tank size must be selected according to the water volume in the solar system from the top of the drainback tank to the top of the highest collector.
High efficiency Variable Speed Solar Control The control included in the STS module operates the circula- tor at variable speed which has been tested to enhance sys- tem performance by 20% and reduce circulator energy use by 50%. This control has many additional functions such as excess heat dump and dual tank control. See the Components section for details.
Accessories STS has a range of solar accessories including piping line sets, insulation covers, sensor wire and much more. Refer to the Components section of the Price List. Example:
Swimming Pool Stainless Steel Heat Exchanger Tanks A perfect product for dumping excess heat from a solar system into the pool or spa. The 10 gallon stainless tank has 1- 1/2” connections for the pool and 1” connections to the cupronickel finned tube heat exchanger immersed in the tank.

STS Residential Solar Hot Water Sizing Residential solar hot water systems work within the daily rhythm of heating the water circulat- ing through the collector(s) during the day and storing the energy in a tank for use during the evening and the following morning. The system needs to offer the most economically sized storage tank and the proper amount of solar collector square footage to meet the hot water demands of a home. The objective is to provide a 65-75% annual solar fraction, which is the amount conventional fuel use avoided by the solar energy contribution. It is important to avoid providing too many square feet of solar collector for a given amount of storage. Such over siz- ing can result in over heated systems resulting in reduced system longevity and poor econom- ics.
Systems are sized according to the daily hot water demand for a building which is determined by the fixture count and the expected number of people to be occupying the building. Below are standard equipment selection guidelines for different household occupancy in Mediterranean zone California/Nevada. More exacting sizing, required for Title 24, can be uti- lizing by utilizing the F-Chart sizing program available through STS or the program can be downloaded free of charge from the California Energy Commission web site www.energy.ca.gov/title24/swh_calculator/index.html

This sizing presumes a 65%-75% solar fraction, 35 degree inclination and orientation within 15 degrees +/- of South. If there are additional loads than domestic hot water, such as space heating, a spa or pool, the solar collector surface area may be increased according to the size and occurrence of the addi- tional load (see Heat Dumping). Sizing single tank Phoenix Solar/ Boiler Solar: While the top of each tank in a single tank solar design is heated by conventional fuel (gas or electric), solar will heat all the tank, including that portion in the top of the tank. Single tank system should be sized with the same methodology as shown above.
