A Supreme Solar 165 LTR water heater holds about 43.6 gallons, but a confirmed U.S. retail price may be difficult to find because the product is not widely distributed nationwide. For budgeting, an imported unit may run about $500-$1,200 before installation, while a complete U.S. solar-water-heating installation can cost $3,000-$7,000 or more, depending on the collector, roof work, backup heating, and local labor.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 165 LTR tank or system equipment | $500 | $850 | $1,200 | Planning estimate for imported or comparable equipment; shipping may be extra. |
| Installed system | $3,000 | $4,800 | $7,000+ | Installed solar thermal system; roof and plumbing conditions affect the total. |
| Installation labor | $800 | $1,600 | $2,800 | Typical planning range for a standard installation, excluding major structural work. |
| Capacity reference | 43.6 gal | 43.6 gal | 43.6 gal | 165 liters converted to U.S. gallons. |

What a 165-liter Supreme solar system may cost
Budget roughly $3,000-$7,000 for a complete installed system, not just the tank. The equipment-only estimate of $500-$1,200 is most relevant when a seller can ship a compatible 165-liter unit to the United States. Freight, import charges, required fittings, and warranty support can change the delivered price.
A 165-liter tank stores about 43.6 gallons, but tank capacity alone does not establish the system’s heating output. Collector design, sunlight, insulation, and whether the package includes a pump or controller all matter. A U.S. installer may recommend locally supported equipment instead if the imported model lacks compatible components or a clear service path.
Which tank, collector, and labor charges shape the quote
Quotes should identify whether they cover a tank alone or a complete solar thermal package. The following ranges are planning estimates for a typical residential job; line items can overlap when contractors bundle equipment and labor.
| Quote item | Low | Average | High |
|---|---|---|---|
| 165-liter tank or storage component | $500 | $850 | $1,200 |
| Solar collector and controls | $700 | $1,300 | $2,200 |
| Plumbing, valves, and fittings | $250 | $500 | $900 |
| Installation labor | $800 | $1,600 | $2,800 |
| Roof mounting, delivery, and disposal | $200 | $550 | $1,200 |
Labor rates vary by location and trade. A rough calculation is , with residential plumbing or solar labor often budgeted at $75-$150 per hour. Ask whether the quote includes commissioning, leak checks, haul-away, and sales tax.
How tank size and collector type change the price
Capacity and collector area need to be priced together. A 165-liter tank may suit a modest hot-water demand, but households with several daily showers or simultaneous uses may need a larger storage volume or more collector capacity. Increasing storage to roughly 200-300 liters can add several hundred dollars to equipment costs, plus any labor required to reinforce or modify the installation.
Collector type also matters. Flat-plate collectors are commonly used in residential systems, while evacuated-tube designs may cost more and perform differently in cold or cloudy conditions. A package with a circulation pump, differential controller, and freeze protection can cost more than a simpler thermosiphon setup. In areas with freezing temperatures, confirm that the design protects exposed piping and collectors; retrofitting protection can add roughly $300-$1,000.
Roof pitch, distance from the collector to the tank, and access affect labor. A roof run longer than about 25 feet, steep roofing, or a tank location that requires opening finished walls can add $300-$1,500 or more. Request a site-specific quote rather than assuming every 165-liter package installs at the same price.
Keep the 165-liter installation price down through scope control
Compare complete, like-for-like quotes rather than choosing by tank price alone. Ask each contractor to list the tank capacity, collector type and area, controls, backup heater, mounting hardware, labor, disposal, and warranty. A low equipment price can become expensive if shipping, compatible valves, or installation parts are excluded.
Keep the existing water-heating layout when it is safe and compatible, and schedule roof and plumbing work together to avoid duplicate service calls. Before approving a larger tank or premium controls, ask the installer to explain the expected household demand and measurable benefit. Do not remove freeze protection or code-required components merely to reduce the initial quote.
For an imported Supreme unit, get the delivered cost in writing, including shipping, customs or import fees, and return terms. Confirm that a U.S. contractor will install it and can obtain replacement seals, controls, and other parts. If local service is unavailable, a supported domestic system may have a higher purchase price but lower repair risk.
Imported Supreme units versus locally supported systems
U.S. shoppers may find that a Supreme Solar 165 LTR listing is priced for a market outside the United States. A foreign listing or converted currency price does not necessarily include international shipping, import charges, local plumbing fittings, or a U.S.-valid warranty. Get the seller’s delivered quote and confirm the model’s voltage and connection specifications before paying.
A locally available solar thermal package may cost more upfront, but installers are more likely to know its parts and service requirements. Compare warranties, replacement-part access, collector specifications, and the full installed price. For either option, ask whether the system is compatible with an existing electric or gas water heater used as backup.
Three example budgets for a 165-liter solar water heater
These examples show how site conditions change totals; they are not quotes for a confirmed U.S. Supreme-branded installation.
| Scenario | Scope | Estimated total |
|---|---|---|
| Equipment replacement | $700 tank allowance, 6 labor hours at $100 per hour, $250 fittings and delivery | $1,550 |
| Standard complete installation | $1,800 collector and controls, $900 tank, 12 labor hours at $110 per hour, $600 mounting and plumbing | $4,620 |
| Steep roof and long pipe run | $2,500 equipment, 18 labor hours at $135 per hour, $1,200 roof and piping work | $6,130 |
The replacement example assumes compatible existing collectors and controls, so it is not comparable to a new complete system. The other examples include broader equipment and installation work, but exclude unusual structural repairs and any local permit fee.
Permits and backup heating can add to the total
Permit requirements vary by city and county. A plumbing or building permit may cost about $50-$500, while required inspections or roof engineering can add more. Before ordering equipment, ask the local building department and installer which permits apply, especially if the project changes roof penetrations, electrical controls, or structural loading.
Many solar water-heating systems use a conventional heater for backup when solar energy is insufficient. If the existing heater is serviceable, retaining it may limit the project scope. Replacing or relocating it can add roughly $800-$2,500, depending on fuel type, venting, electrical work, and code updates. Check current utility incentives directly with the utility or local program; eligibility can depend on equipment certification and installation requirements.
