Services
Solar Heating Systems
Our solar space heating systems integrate with domestic hot water systems to provide year-round warmth. Using 5-10 solar panels and 400-700 gallons of storage, these systems capture and store solar energy for efficient home heating. Our proprietary tank designs improve insulation and reduce maintenance while delivering up to 70% savings on combined heating and water bills.
Radiant Floors
Solar-powered radiant floor systems use low-temperature water for energy-efficient home heating. By storing heat in flooring materials, they optimize solar energy use and reduce stratification. Our systems integrate with solar tanks and boilers to maintain consistent comfort while lowering energy consumption through natural heat distribution.
Boilers
We integrate solar technology with high-efficiency boiler systems for hybrid heating solutions. Solar energy preheats water stored in insulated tanks, reducing boiler workload during peak seasons. This combination delivers reliable heating with lower operating costs while maintaining compatibility with existing gas or electric backup systems.
Solar Hot Water
Our drain-back solar hot water systems use 2-4 panels and 80-160 gallons of storage to reduce water heating bills by 80%. The non-pressurized design eliminates maintenance issues associated with glycol systems. With automatic differential controllers and gravity drainage, these systems offer over 50 years of durability and require service only every 5-10 years.
Pool Heating
Solar pool heating systems utilize panels optimized for low-temperature operation, eliminating the need for storage tanks. The pool itself acts as thermal mass, maximizing efficiency and return on investment. These systems provide cost-effective heating for residential pools and spas while leveraging Colorado's solar potential for year-round use.
Questions
What's the difference between solar thermal and solar electric systems?
Thermal systems heat water directly, capturing 60-80% of solar energy. Electric (PV) systems convert sunlight to electricity, capturing 12-18%. Thermal panels produce roughly four times more energy per square foot at lower costs.
What financial incentives are available for solar thermal systems?
The federal residential clean energy credit provides a 30% tax credit through 2032. This reduces system costs significantly, with decreasing percentages applying in 2033 and 2034.
How long do solar hot water systems last?
Properly maintained systems last over 50 years. Storage tanks typically require replacement every 15-25 years. Drain-back systems need service every 5-10 years due to their low-maintenance design.
Can solar heating systems work in cold climates?
Yes. Our systems combine solar thermal storage with boiler backups to ensure reliable heating even during Colorado's coldest weather. Proprietary tank designs optimize heat retention and efficiency.
Do you offer commercial solar solutions?
We provide customized solar heating and hot water systems for commercial properties, including radiant floor integration and large-capacity storage solutions tailored to business energy demands.
How do radiant floors interact with solar systems?
Radiant floors use solar-heated water through a loop system connected to storage tanks. Mixing valves regulate temperature, while boiler backups ensure consistent performance during extended cold periods.
