Solar Hot Water Systems: Are They Worth It for Longmont Homeowners?
What Is a Solar Hot Water System?
A solar hot water system uses sunlight to heat water for your home. Unlike regular solar panels that create electricity, these systems use thermal collectors to warm water directly. It’s a separate but complementary system to other home solar solutions.
For Longmont homeowners looking to cut utility bills and reduce natural gas use, solar hot water systems offer a practical option.
How Solar Hot Water Systems Work
These systems have three main components: solar collectors, a storage tank, and a control system. The collectors, often installed on your roof, absorb sunlight and use it to heat a fluid. This heated fluid then transfers the heat to your home’s water tank.
There are two types of systems:
- Active systems: Use pumps to move the heated fluid
- Passive systems: Rely on gravity and natural convection
Active systems are more efficient, especially in colder climates like Colorado, where freeze protection is essential.
How Much Do Solar Hot Water Systems Cost?
The cost for a solar hot water system in Longmont typically ranges from $6,000 to $11,000. This includes installation, equipment, and permitting.
While it’s a significant upfront investment, local and federal incentives can lower the net cost:
- The federal solar tax credit covers up to 30% of the system cost
- Colorado offers property and sales tax exemptions for solar equipment
- Some utilities provide rebates for solar water heating systems
Flatiron Solar can help you apply for these incentives as part of the installation process.
Do Solar Hot Water Systems Save Money?
Yes, they can. A solar water heater can cut your water heating costs by 50% to 80%, depending on your household size and usage.
In Longmont, where natural gas is common, switching to solar water heating can reduce your gas bill significantly. Over time, this can save you thousands of dollars, especially as utility rates go up.
Can I Use Solar Hot Water with My Existing Solar Panels?
Yes. Solar hot water systems work independently from solar panels used for electricity. They don’t draw from your power system, so you can use both together without interference.
Combining solar installation for both electricity and hot water increases your home's energy independence and long-term savings.
Maintenance and Lifespan
Solar water heaters need less maintenance than many people expect. Annual checkups are usually enough. The system’s components—collectors, pumps, and tanks—typically last 15 to 20 years.
Regular service from your installer, like Flatiron Solar, ensures everything stays efficient and safe.
