FloridaSolarHotWater.com's 'Skyline' Open Loop System is easily installed on a metal or concrete roof, without the use of a crane, 3 rectangular panels heat the cold water that is pumped through them from the storage tank in the house. The pump action is powered by the small solar photovoltaic panel.


Being the only person on the street with piping hot water after a hurricane might not be something people with solar hot water brag about, besides, having the whole neighborhood lined up outside the bathroom isn't an enviable predicament to be in, but bragging about the reduction in electricity costs, as well as the reduction in fossil fuel emissions equivalent to taking one car off the road, this is something most of them shout loudly from the roof tops.
And one that Florida Sea Grant Marine Agent, County Director UF, Monroe County Extension and board member of the Green Living and Energy Expo (GLEE), Doug Gregory supports, and is confident it is the best step any Keys resident can take.
"Solar Hot Water systems can pay you back in 3 to 6 years, they cost about $3000 to $4000, whereas electric solar photovoltaic (PV) panels start at about $20,000 for a standard residence, and take a long time to recoup the cost, about 30 years. We really need to push the solar hot water heaters, we really have no electricians to install the solar PV panels, it requires a plumber to do the solar hot water," he says.
State and federal incentives help people to do this; with $2500 available, the final cost can be as low as $1500 for a certified plumber installed, new system.
Solar water heaters start life on the roof, they can weigh anything from 19 lb's for the more modern forced circulation system that requires an adjacent small solar power (pv) panel to run it, and up to 500 lb's for the older passive water heaters that contain 40 gallons of water and rely on convection to circulate it, they both resemble skylights.
They are basically aluminum boxes covered in tempered glass that contain coils or fins through which water circulates as the sun heats it. Plumbed down to the household water tank, the water cycles downhill to fill the tank, which, in an average sized home is enough to fill either a 40 or 80 gallon tank. The water can get up to over 160 Fahrenheit, and, nowadays, wind stress being an issue in the Keys, the 150 mile an hour wind-load standards have resulted in increased engineering specifications.
"We thread rod them through the ply wood in to the truss, so if the roof stays on in a storm, chances are your panel will stay there," says Thomas Haskins, of Haskins Plumbing in Key West, even if the glass breaks on the panel, it's tempered glass like in the car wind shield, and as long as the glass is not leaking, then it still supplies hot water.
The more modern systems can easily supply an entire household's hot water needs from the suns energy, and if there are too many cloudy days, heating the water the traditional way is accomplished by the flick of a switch, back to the grid, or a cool shower.
And while people have been known to self-install these lighter weight systems successfully, most start as a first step with a web search, or a call to the power companies to link up with certified installers and plumbers. The first thing they learn is that all of the pieces and parts come from out of town, and locally certified talent is thin.
The biggest boon, despite the relative lack of local solar goods, personnel and technical support, is probably the words of encouragement from some in the community, as well as, increasingly these days, some in the local power industry.
"We do recommend that, especially if your building a new house to put solar water on it, with the increases in fuel prices it's probably more cost effective now, even retrofitting with solar water heaters is part of the equation, more than in the past when that was cost prohibitive. The current environmental issues are in the news all the time, I think you'll see more solar applications in general," says Scott Newberry, Chief Executive of the FKEC.
But, are these actions enough to usher in a truly green era of living in the energy inefficient Keys? It will only be truly in the power companies' interests if they are the ones selling and installing the panels in the first place.
At present the most driven people around the Keys to want solar water heaters are building contractors, but officials and solar water heater suppliers that have dealt with the contractors of the Keys on a weekly basis for years, say they almost all driven by the value of that extra ROGO point, more than environmental consciousness.
"Basically almost everyone that comes into ROGO puts that down, solar hot water, heat recovery, or solar panel, they come in one way and then get their point and then change to a heat recovery system," says Tiffany Stankiewicz, Monroe County Sr. Planning Technician in Marathon. She says the ROGO point will go away when the Tier system takes effect, no one yet knows what will replace it.
In fact the fate awaiting anyone who makes inquiries as to where to buy and how to install a solar water heating system, is still a bit of a self-motivated leap of faith, "just keep swimming," is putting it mildly. The fact is, at this stage the locally contacted power companies aren't much more helpful than suggesting websites where certified solar water heater contractors may be found, or offering to sign alternative energy conscious people on to their new, 'premium' green energy services.
As for certified plumbers that can install the systems, two out of the three listed on the suggested Florida Solar Center website for Monroe County, did not reply to phone calls, but state certified and available by phone, is the solar-man in the Keys, Thomas Haskins.
"I like doing solar, most people don't know this is one of the ways you can save energy, help the environment and it pays you back up to $80 monthly, you are no longer as reliant on City electric. Once you've had the hurricane, you'll still have the power for the hot water, also an option to consider when a traditional water heater goes bad, instead of replacing that energy bighting old system, this is where the future lies," he says.
He installs about a dozen units a year, 3/4 of which he says are ROGO point getters and the rest are the environmentally conscious people who want to save money.
But recently he's been replacing hurricane-damaged panels, which touches a nerve that can stop people in their solar tracks.
"The Ocean Key House Hotel suffered hurricane damage on their panels from roof debris, the glass shattered, but did not leak, we put 6 brand new ones on, they have 18 panels on their roof," he said.
And although solar collectors littered streets around Key West after Wilma, so did mattresses, screen cages and roof top pieces, and, as people did not go without replacing their beds, roofs and screens, similarly, solar water heater owners upgraded and renewed their systems.
"Because they realized the value of what they had," says Dale Gulden, CEO of the Florida based company, Solar Direct, who has seen a 3 or 4 fold increase in installation's in the Keys since Wilma, now there are stricter wind load criteria.
As for the 5 local government offices contacted in the matter of solar water heaters, the permit office was happy to quote the costs of permitting them and these varied wildly from $52 up to $180, the building office read off a list of objections, and none have yet to recommend solar hot water over the older power greedy 'heat recovery' alternative, but one suggestion was to supply people with a standard for installation on all different roof types.
"If someone was putting in one, they would have to supply the engineering information as part of the permitting process. If they can supply a standard engineering form for a concrete roof, metal roof etc, we'd keep a master on file, and if we could make it easier and cheaper for people, then we would do that," says Key Colony Beach's Building Official, Edward Borysiewicz.
Suggestions as forward thinking as this stand alone, the overwhelmingly negative municipal comments say it all; 'people just don't want to go up there on the roof, that's why it isn't popular,' and 'my brother loves his, but I don't think it'll catch on,' and 'we recommend heat recovery systems' and 'this kind of thing will void a roof warranty,' or 'you'd need to pay a certified engineer or architect to go up there and inspect it before we'd be willing to grant the permit.'
It's no surprise there is little interest, add to it the huge discrepancy in permitting regulation and costs that pertain to solar water heaters up and down the Keys.
Beyond this governmental quagmire, a more simple matter is money. If there is nothing financial in it for many people, there is just no interest. Local power magnates only make money out of green energy if customers sign up for their premium 'green,' services, not if people by-pass them and reduce their electric bill by up to 50% with solar hot water. And certainly not if they go the more expensive route to complete energy independence with solar (pv) power, as a small handful have found the rather larger investment resources of an initial $20,000 to do.
But on the start small solar frontier, local's like Haskin's in Key West, whose father and he have been converts for the last 25 years or more, to sun heated showers, may smile knowingly as Governor Charlie Crist becomes the latest Floridian political celebrity to install a solar water heater to warm his pool and a hydrogen fuel cell to power the rest of his magnanimously re-named 'people's mansion' in Tallahassee, but are those that need to be convinced by his acceptance of the greening revolution actually listening?
Stirrings are heard in the halls of power around the Keys community, now notorious for it's energy inefficiency, as energy efficiency action plans and reports are being printed, perhaps even on recycled paper and officials seek alternative energy ideas, it remains to be seen if there will be a concerted effort in getting institutions and individuals away from the use and abuse of nuclear, gas, oil and ethanol as more destructive sources of power, despite the wave of reluctance that awaits those interested in doing so.
Sugarloaf Shores resident Sven Fris Jr. does not hear the detractors, he just loves his solar hot water and will be keeping it, regardless of the potential for damage from hurricanes, cold showers on cloudy days and roof top maintenance or voided roof warranties.
"We installed ours in 1998, the cost then was $2000, and there were no incentives. We had our panel mounted low to the roof to minimize uplift from wind, we have been so pleased with it, and have no complaints," he says it has gone through every hurricane since Georges and the bigger 80 gallon storage tank easily serves himself, his wife and guests, they switch back to electric power when it's cloudy.
Titusville based FloridaSolarHotWater.com sold a 'Skyline' open loop system recently to one commercial airline pilot in Key Largo, made to supply 85% of the hot water needs to a home, in the Florida climate, and pay for itself in 3 to 6 years, it is ample for his 5 person family, even with the smaller 40 gallon storage tank, and he likes the savings.
Key Largo resident and Green Living and Energy Expo steering committee member John Hammerstrom and his FIU Professor wife have enjoyed their 40% solar powered sustainable materials home since 2002, they have a 40 gallon passive Solar Direct PT-40 system like the one their United Airlines friend Ed Yost also has on his roof. It stores the water in the coils within the casing, which makes it weigh a whopping 500lbs, when functioning.
And on Plantation Key, Mike and Gay Purvis plan to replace their on-demand water heater with a solar water heater from Solar Direct, some time this year.
"It's just the last thing we can do to really make this place energy efficient, we are doing this for the little ones, you know, the next generation," says Gay Purvis of her 8 year old son, Ethans' future.
