Living with off grid solar often means finding alternative ways to meet daily needs without relying on public utilities. One essential comfort is access to hot water for bathing, washing dishes, and more. In areas where reliance on the electrical grid is not preferential, off-grid hot water systems provide this comfort through renewable resources like solar power.
These systems capture heat from the sun’s rays to warm water stored in insulated tanks. These systems capture heat from the sun’s rays to warm water stored in insulated tanks.
Options range from basic solar collectors, effective even during winter months, to more advanced heat pump systems. Key benefits of water heat pumps include sustainability, reliability during power outages, and independence.
When choosing an off-grid hot water system, there are several options to consider:
Electric water heaters, harnessing heating elements powered by pv panels and batteries, provide readily available and heated water tucked away in insulated tanks. Simple to install and operate, they work well for summer use but may lack capacity in winter.
Propane or LPG systems provide hot water via gas burners. They provide reliable hot water in all seasons but require fuel delivery and storage tanks.
Rooftop solar hot water systems use panels to capture heat and transfer it directly or via heat exchangers to an insulated storage tank. Though more complex, a solar hot water system is sustainable year-round.
On-demand propane or electric tankless heaters ensure there’s no lag time in providing hot water, so you’re never caught out with there no immediate supply. They conserve space but can lack capacity for simultaneous uses.
Wood-fired boilers, acting as robust heaters, can toast renewable biomass fuel to heat fluid circulating towards a separate insulated tank. Though requiring hands-on effort, they utilise onsite fuel sources to produce off grid hot water.
Using solar water heating harnesses power from the sun to ensure your hot water needs are met sustainably. These systems use solar thermal collectors mounted on the roof to absorb heat from sunlight. This solar energy gets transferred to water stored in an insulated tank ready for use.
There are two main types of solar collectors used: flat plate and evacuated tube. Flat plate collectors are less expensive but evacuated tube types are more efficient at capturing solar energy. However, both options rank among the most efficient methods to heat water when sized and angled appropriately.
Harnessing solar power delivers water solar heating with key benefits like sustainability, lower energy bills, and reliability, even amid power failures.
And using free renewable solar power means less reliance on fossil fuels. Just note that output falls on cloudier winter days. And using free renewable solar power means less reliance on fossil fuels.
With some upfront investment, solar water heaters provide a cost-effective, eco-friendly way to meet hot water needs off the grid year-round.
Wood-fired water heaters give a steadfast grid hot water solution, using renewable biomass to sidestep reliance on gas or electricity. Their operation is such that the heater can elevate the temperature of a water jacket or coils by igniting wood within an encased firebox. This heated water then circulates through pipes to an insulated storage tank, ensuring your water is always ready for household use.
Compared to intricate solar systems, wood-fired heaters have the competitive edge of functioning in all weather conditions and can be a robust addition to your solar system. And they circumvent more than the hassle of fuel delivery or storage by utilising onsite wood sources. However, they demand effort for gathering/preparing wood and stoking the firebox two to three times daily, with frequency variable with usage.
Thermostatically-controlled electric circulation pumps make this process more autonomous, appealing to those seeking the best options out there.
Wetback-style systems with your water tank directly attached, though compatible with off grid solar hot water designs, pose risks like steam buildup leading to explosion. External wood boilers feeding a separate tank are safer. Correct installation following standards, plus using seasoned hardwoods, are key to efficient, trouble-free operation.
For remote cabins or rural living offgrid, wood-fired water heating offers a rugged, time-tested solution to supply ample hot water completely off the traditional grid.
Propane or LPG (liquefied petroleum gas) water heating systems work by burning propane to heat water stored in insulated tanks ready for use. A gas burner or heating elements create the heat which gets transferred to the water.
Unlike the weather-dependent solar water heater systems, propane heaters supply hot water reliably across diverse climatic conditions. And without solar panels or plumbing connections, LPG systems have lower installation costs. Refilling propane tanks is required yet still allows independence from grids or wood gathering.
Propane heaters can serve your home well as an affordable, low-maintenance off-grid solution to meet hot water needs. Make sure to size the LPG tank capacity and delivery schedule to support household demand year-round.
While the initial outlay is higher, heat pumps can save a lot over time in energy costs, proving to be an efficient hot water solution that uses just a trickle of electricity. They harness ambient warmth from the air or ground into water, thus transferring more energy to be stored in an insulated tank. While the initial commitment is higher, hot water heat pumps can slash your water heating costs significantly, often more than half.
Heat pumps can use ambient warmth effectively in warmer climates but lose efficiency below 40°F. So a supplemental heat source helps ensure adequate hot water in cold weather. Overall, heat pumps are a robust off-grid option where minimal solar or wind power is available.
When selecting an off-grid hot water system, understanding the costs can help play a key role in decision making. Here’s an overview of typical expenses:
While electric and LPG water heaters have lower initial costs around $800-$2,000, solar setups can be more expensive initially. Solar systems run $2,500-$5,000 installed. Wood-fired boilers start around $2,000 but installation can be more costly than larger solar options, adding $2,000-$5,000 or more.
Electric heaters paired with an efficient solar pv system, like an off-grid setup, boast minimal running costs, thus championing energy independence. LPG refills for gas heaters average $100-$300 yearly depending on use and tank size.
Wood-fired boilers use free biomass fuel gathered onsite. Wood-fired boilers use free biomass fuel gathered onsite.
Heat pumps provide the greatest efficiency. Solar water heaters rank second when sized properly. Wood-fired and LPG systems follow.
Considering all costs in a long-term perspective facilitates pinpointing the best solution for your hot water system.
The task of installing off grid hot water systems mandates meticulous planning to accommodate spatial, ventilation, and structural requirements. Getting professional help drafting plans and making connections ensures code compliance and safety.
All systems also need some maintenance.
Solar collectors require occasional glass cleaning and leak checks. Wood boilers need ash removal plus gasket and component replacement over time. Heat pumps and tankless heaters use filters needing regular change-outs.
Any complex system may need tending to. For instance, pump solar components, control boards, heating elements, and storage tanks may falter. Having Riverwood Plumbing’s expertise on hand provides peace of mind to keep off-grid hot water flowing.
Properly sizing and positioning a hot water system maximises its efficiency. When relying on solar power especially, a south-facing sunny exposure is key to harvesting ample renewable energy.
As a rule of thumb, size the solar collectors to meet demand during winter when sunlight hours are fewer. For a 3-4 person household, flat plate collector area should total around 15-20 square feet. Evacuated tubes can get by with less space due to higher efficiency.
Hot water tanks sized 50-80 gallons are frequently chosen to suit your hot water system needs in off-grid homes. Locate them as close as possible to solar panels or boilers to minimise heat loss in pipes. Keep adequate ventilation around fuel-burning equipment too.
