Solar Heating FAQ
How does solar heating work during cloudy days?
Our solar heating systems are designed with efficiency in mind. Even on cloudy days, the collectors can absorb diffuse sunlight and convert it to usable heat. All systems include backup heating options (electric or gas) that automatically activate when solar output is insufficient, ensuring you never run out of hot water or heating.
What maintenance does a solar heating system require?
Solar heating systems require minimal maintenance. We recommend an annual inspection to check fluid levels, pump operation, and collector cleanliness. The system should be flushed every 3-5 years, and antifreeze levels should be checked before winter. Our collectors are self-cleaning during rainfall, and the durable materials require no regular upkeep.
Can solar heating be used for pool heating?
Absolutely! Solar heating is ideal for pool applications. We offer specialized pool heating systems that can extend your swimming season by several months. These systems use unglazed collectors that are highly efficient for pool temperatures and can typically raise pool temperature by 5-10°C, depending on weather conditions and pool size.
Installation Requirements
- South-facing roof space (or within 45° of south)
- Minimum 10 square meters of unshaded area
- Standard household water pressure
- Electrical connection for control system
- Structural capacity to support collectors (approx. 30kg/m²)
Performance Data

| January | 8.2 | 45% |
| April | 14.7 | 78% |
| July | 18.3 | 92% |
| October | 12.5 | 68% |
More Solar Heating Questions
How long does a solar heating system take to pay for itself?
The payback period for solar heating typically ranges from 4-8 years, depending on your local energy costs and sunlight conditions. With rising energy prices, many systems now pay for themselves even faster. Government incentives can reduce this period further. After the payback period, you're essentially getting free heating for the remaining system lifespan (15-25 years).
Are solar heating systems compatible with radiant floor heating?
Yes, solar heating works exceptionally well with radiant floor systems. The lower temperature requirements of radiant floors (typically 35-45°C) make them ideal partners for solar thermal systems. We offer specialized combi-systems that can provide both domestic hot water and radiant floor heating, with smart controls to prioritize heat distribution where it's needed most.
What's the difference between solar thermal and photovoltaic systems?
Solar heating (thermal) systems directly capture the sun's heat to warm water or air, while photovoltaic (PV) systems convert sunlight into electricity. Solar thermal is much more efficient for heating applications - our collectors convert over 80% of sunlight into usable heat, compared to about 20% efficiency for PV panels. For water and space heating needs, solar thermal systems require much less roof space and provide better return on investment.
Financial Incentives
Many governments offer incentives for solar heating installation:
- Federal tax credits up to 30% of system cost
- State-level rebates (amounts vary by location)
- Property tax exemptions
- Sales tax exemptions
- Renewable energy certificates (RECs)
Solar Heating System Selection
How do I determine what size solar heating system I need?
System sizing depends on three main factors: household hot water usage, available roof space, and climate. As a general rule, allow 1-1.5 square meters of collector area per person in the household. For space heating, we calculate based on your home's heat loss and local climate data. Our experts perform detailed site assessments to recommend the optimal system size for your specific needs.
Can solar heating be installed on flat roofs?
Yes, solar heating systems can be installed on flat roofs using special mounting frames that angle the collectors toward the sun. We recommend a tilt angle between 30-45 degrees for optimal year-round performance in most climates. Flat roof installations may require additional structural assessment and ballast systems to prevent wind uplift.
What happens if my solar heating system produces more heat than I need?
Our systems include several safeguards against overheating. Excess heat can be diverted to a heat dump (like a swimming pool or outdoor hot tub), stored in larger buffer tanks, or simply allowed to stagnate (modern systems handle stagnation safely). During summer months when heating demand is low, the system will automatically regulate itself to prevent damage while maintaining readiness for when heat is needed.
