YALICE Water Heaters, Solar Power Water Heater Electric
The YALICE YLS100GF is a hybrid storage water heater designed to integrate with solar panels while providing AC backup. It holds 26 gallons (100 L) suitable for handwashing, grooming, pet baths and single-shower scenarios. The unit supports solar-electric hybrid operation with a 3200W tank heater working alongside up to 1200W AC solar panels (solar panels not included). It automatically switches to household AC power during low-light or nighttime conditions.
Control features include an adjustable thermostat from 86–167°F (30–75°C), LED display, timer scheduling, remote control, and one-touch AC/DC heating mode selection. These options help manage energy use when operating on solar-derived electricity. The hybrid design reduces grid reliance for hot water but requires a compatible PV array or inverter capable of delivering the specified AC input.
Dr Infrared Heater DR-238 Carbon Infrared Outdoor Heater
The DR-238 carbon infrared heater is rated IP55 for both indoor and outdoor use, which makes it suitable for patios, garages, and semi-enclosed spaces that may be paired with solar power systems. It delivers clean, instant infrared heat and offers three power settings: 900W, 1200W, and 1500W. The heater runs on standard 120V, making it compatible with many inverter outputs used in solar installations.
Infrared technology warms objects and people directly, which can be more efficient than heating air in windy outdoor scenarios. The plug-and-go capability with remote control supports flexible operation. When used with solar, lower watt settings or battery-backed inverter operation can prolong off-grid run time.
Star Patio Outdoor Patio Heater, Infrared Heater With 180° Oscillation
The STAR PATIO infrared heater uses honeycomb-shaped heating elements and offers 180° oscillation to distribute radiant heat across seating areas. It is a 1200W electric freestanding unit designed for outdoor use and claims performance to heat up to roughly 110 sq. ft. Infrared operation is effective in light wind because it heats surfaces directly rather than relying solely on air temperature.
For solar applications, the focused infrared output at 1200W can be practical when combined with a modest solar inverter and battery bank, or for use during peak sun hours with direct PV-driven AC systems. The heater’s design aims for energy-efficient performance compared with some higher-wattage gas alternatives.
Outdoor Heaters for Patio, 1500W Electric Garage Heater with Remote Thermostat
This Riseon 1500W PTC ceramic heater targets garages, greenhouses and tents and includes a remote, touch controls, and an adjustable thermostat with three operating modes: ECO, Low, and High. Its smart thermostat cycles heat to maintain set temperatures between 41°F and 95°F. The unit also includes ETL-certified overheat protection and a child-lock function.
PTC ceramic elements offer rapid warm air and self-regulating behavior that can be favorable for solar-powered installations because they avoid runaway current draw. For off-grid use, the unit’s multiple modes let owners reduce power consumption by selecting ECO or lower settings when running from stored solar energy.
Envi Plug-in Electric Panel Wall Heaters For Indoor Use
The ENVI plug-in electric panel heater is a low-wattage wall-mounted option designed for continuous, quiet operation. Its fan-less “stack convection” design provides gentle warmth at a cool surface temperature (about 90°F) and is intended for 24/7 supplemental heating in rooms where constant background warmth is preferred.
Key safety attributes include a wall-sense sensor that cuts power if the unit is removed, and the absence of a fan limits dust and allergen circulation. Because the heater operates at low wattage and is designed for continuous use, it pairs well with small solar systems or energy-conservative strategies where modest, steady heating is desired.
Buying Guide: Choosing A Solar-Compatible Electric Heater
Selecting a heater for use with solar power requires focusing on efficiency, compatibility, and realistic expectations about runtime and output. Below are the main factors to consider.
Power Demand And Solar Capacity
- Match Wattage To Solar Output: Compare heater wattage (e.g., 900–1500W) with your inverter and PV array output. High-watt units need larger inverters and battery capacity for off-grid use.
- Use Lower Power Modes: Heaters with adjustable modes (ECO, Low/Medium/High) extend run time on limited solar resources.
Type Of Heat Delivery
- Infrared vs. Convection: Infrared heats objects and people directly, often feeling warmer at lower air temperatures—beneficial outdoors or in drafts. Convection and PTC ceramic heat the air and are suited for enclosed spaces.
- Water Heating: Solar-electric hybrid water heaters store heat and reduce grid use for hot water, often being more efficient for domestic hot water than space heating with resistive elements.
Duty Cycle And Installation
- Continuous Use: Low-watt wall units are intended for 24/7 background heating and pair well with modest solar setups or grid-tied systems that export during the day.
- Portable/Intermittent Use: Portable infrared or ceramic heaters suit short-term spot heating and perform best when used during peak solar production or when battery reserves are available.
Safety And Certifications
- Look For ETL/UL/CE: Certified safety helps ensure components handle continuous operation and meet electrical safety standards.
- Overheat & Tip-Over Protection: Essential for portable units operating in rooms with occupants or pets.
- IP Rating For Outdoors: For patios or semi-exposed areas choose IP-rated units (e.g., IP55) appropriate for moisture and dust exposure.
Integration With Solar Systems
- Grid-Tied Vs. Off-Grid: Grid-tied systems can run heaters directly during daylight hours when PV production is high. Off-grid requires sufficient inverter and battery capacity to support continuous or high-watt loads.
- Inverter Sizing: Ensure the inverter’s continuous rating exceeds the heater’s draw and consider startup currents if applicable.
- Direct-AC Solar Systems: Some setups allow AC loads to be prioritized to on-site PV during production peaks; hybrid water heaters that accept both solar and AC inputs simplify operations.
Efficiency Strategies
- Heat Where You Need It: Use spot infrared heaters for occupied zones rather than heating entire buildings.
- Schedule Operation: Time heater use to coincide with peak solar generation or when batteries are full to maximize renewable consumption.
- Insulate And Seal: Improve room retention with weather-stripping and insulation to reduce required runtime and conserve solar energy.
Other Comparison Perspectives
- Operational Cost vs. Output: Compare kilowatt draw and duty cycle—lower-watt continuous units may cost less to operate over time than short bursts from high-watt heaters when solar is limited.
- Portability vs. Permanence: Portable models provide flexibility but may be less efficient than dedicated panel heaters or wall-mounted units that deliver consistent comfort.
- Indoor Air Quality: Fan-less panel or infrared heaters produce minimal air movement, benefiting allergy sufferers compared with forced-air heaters that can circulate dust.
