Phoenix Solar Heating Distribution96% Water Heating / 96% Space Heating / Solar

Solar & Hydronics

Phoenix Solar combines the superb features of the Phoenix 96% mod-ulating stainless steel combi water heater with solar thermal…all inone SRCC OG300 performance certified appliance! This merging ofexisting technologies not only provides superb energy performancebut excellent value by eliminating redundant components, makinginstallation easier and saving space.

The Optimum Mix - All In OnePhoenix Solar Systems provide the optimum financial mix of highsolar domestic hot water solar fraction (65% to 75% of total load), asmall, cost effective solar space heating solar fraction (10% to 20% oftotal load ) and very high efficiency utilization of conventional fuelsources.

New Construction ValueThe addition of solar to the Phoenix water heater provides an excel-lent investment while producing ample Title 24 credit and displacingTONS of carbon emissions over 10 years.

Single Tank DesignThe Phoenix Solar is designed as a fully stratified one tank system.While solar can heat all the tank, the gas fired storage is completelythermally isolated in the top ? of the tank to provide primary hotwater and space heating requirements. Care should be taken in sizingthe system. For example, a 119 gallon Phoenix Solar tank will have 60gallons of gas fired storage available, so care should be taken in esti-mating the peak hot water loads for the building, with special atten-tion to whirlpool baths. Rated input of the heater can be increased toprovide greater hot water recovery, if required.

Residential and CommercialA single Phoenix Solar system is available in a variety of capacitiesthat can serve the needs of a 2000 sq ft home or a 6000 sq ft man-sion. For commercial applications, large loads combined with the 30%uncapped federal solar hot water tax credit and ultra high efficiencyutility rebates, in some areas, make for very attractive returns oninvestment for a wide range of commercial building owners. MultiplePhoenix Solar heaters can meet large water and space heating loads.

Solar Integration with a Hydronic BoilerIntegrating a condensing boiler with solar hot water heatingprovides the great efficiency advantages of 95%+ combinedhydronics with renewable energy in one lean package which isa far superior solution to tankless or conventional hot waterheaters.

Single Tank Systems: Save Space and $A single tank systems employ a storage tank with two hotwater heat exchanger coils, the solar one in the bottom of thetank and the indirect fired coil in the upper portion of thetank. These tanks are designed for thermal isolation of the topand bottom portion of the tank. This system is very popular inEurope because it saves both space and the additional cost ofa separate tank.

Single Tank SizingBecause only one of the storage tank can be counted upon forgas fired water heating storage, care should be taken in sizingthe system. For example, a 119 galloon tank will have 60 gal-lons of gas fired storage available, so care should be taken inestimating the peak hot water loads for the building, with spe-cial attention to whirlpool baths. Generally speaking, homeswith more than 3 bathrooms should employ a two tank sys-tem design.

Two Tank High Capacity SystemsTwo 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 firedstorage for high capacity systems used in large homes. Thissystem can also use the Storage+ control and piping strategyto further expand solar utilization.See Solar StoragePlus System on the next page.

The single tank Boiler Solar System saves space and installation costs using a single tank for solar andconventional hot water.

The dual tank Boiler Solar System provides more solarstorage for high capacity hot water systems.

Solar Hot WaterSolar Thermal Systems

Solar Booklet_0409

The Way Its BeenSolar hot water systems usually deliver solar hotwater to a conventional water heater only whenthere is domestic hot water demand. If there isno domestic demand a conventional gas firedwater heater is usually turning on and off dueto 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 andvirtually eliminates the use of auxiliary heat dur-ing most months of the year. When the solartank has reached operating limit during the day,a second circulator pulls solar hot water into thegas water heater, keeping the solar system oper-ating at acceptable temperatures.

StoragePlus Increase Total System EfficiencyBy 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 addingmore solar energy for domestic hot water

How It Works: STS systems use Taco SmartsThe STS control/pump module uses the Taco VT variable speed solar control. This controlnot only increases solar collection effectiveness by 20% but also has the ability to switchon a secondary circulator when the solar tank reaches operating limit, pumping solar hotwater into the gas water heater, sensing the temperature in the conventional waterheater and turning off the secondary circulator when the operating limit is satisfied orsolar 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 thusgas/electric tank inefficiency is far less relevant economically. A tankless is more efficientthan 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 waterheaters accommodate hot water recirculation systems most effectively.

Types of Systems Solar Thermal Systems

Solar Booklet_0409

Active Systems or Passive SystemsActive solar systems are those that employ a circulator and solar control to actively circulatewater through the solar collector(s). Passive Systems are those without a circulator/control thatrely on natural thermosyphon of heat from a tank or direct heating of a tank on the roof (batchheating). STS provides active systems because they are typically more efficient, more estheticallyattractive, and can store solar energy more efficiently.

Freeze ProtectionMany thousands of solar systems where lost to freezing collectors and water corrosion in the1980s’. This is why we recommend only systems that are isolated from potable water and havepositive freeze protection.

Closed Loop/ Glycol: STS Preferred SystemsThese systems use a heat exchanger to isolate domestic hot water fromthe solar collectors. They use anti freeze within the solar loop to pro-vide the best positive freeze protection. This type of system alsoreduces system corrosion for a long system service life.

DrainbackDrainback systems are designed to drain the water in the system fromthe solar collector(s) so there is no fluid to freeze in the collectors.These are very effective systems when adding additional solar surfacearea to a system for space heating or other applications. The pipesmust be slanted correctly to assure draining the collectors.

Open LoopThese solar systems circulate potable water directly through the solarcollectors. Due to freeze problems and corrosion in the past, STS doesnot recommend the use of these systems in California/Nevada.

Single Tank and Two Tank System DesignA single tank design, which is very popular in Europe, stores both the solar and conventional hotwater in a single tank with special thermal traps. These systems save both equipment costs, spaceand 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 meettheir capacity with roughly three bathrooms or about 4,000 sq ft. Consult us for hot waterdemand sizing. Two tank designs are useful for large homes with very large hot water demands orwhen a client wants a larger solar space heating participation with a Phoenix Solar system.

Phoenix Solar TanksIntegrated Solar and Gas Fired Tanks available in 80 and 119 gallons and 130 and 199 MBH.

Drainback TanksSTS offers drainback tanks from 10-20 gallons, with or without an internal heat exchanger, all including a site glass.

CLOSED LOOP INSTALLATION KITSEach 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 freezefluid must be purchased separately.

Drainback Installation KitsEach drainback system will require a drain-back tank, a bronze or stainless steel circu-lator and a solar control, in addition tothe solar tank and collector(s). The TacoVT series integrated pump/control is agood choice for drainback systemsbecause they use less energy. Drainbacktank size must be selected according to the water volume inthe solar system from the top of the drainback tank to thetop 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 useby 50%. This control has many additional functions such asexcess heat dump and dual tank control. See theComponents section for details.

System Sizing Solar Thermal Systems

Solar Booklet_0409

STS Residential Solar Hot Water SizingResidential 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 theevening and the following morning. The system needs to offer the most economically sizedstorage tank and the proper amount of solar collector square footage to meet the hot waterdemands of a home. The objective is to provide a 65-75% annual solar fraction, which is theamount conventional fuel use avoided by the solar energy contribution. It is important to avoidproviding 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 determinedby the fixture count and the expected number of people to be occupying the building. Beloware standard equipment selection guidelines for different household occupancy inMediterranean 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 bedownloaded free of charge from the California Energy Commission web sitewww.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, thesolar 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 orelectric), solar will heat all the tank, including that portion in the top of the tank. Single tanksystem should be sized with the same methodology as shown above.
