Rinnai i060CN Condensing Boiler
The Rinnai i060CN is a compact, wall-mounted condensing gas boiler designed for whole-home heating and domestic hot water. Its stainless-steel heat exchanger and modulating wire mesh burner optimize efficiency, while a built-in domestic hot water plate heat exchanger supports showers and faucets without a separate heater. The unit enables multizone control through an integrated pump system, and safety features include a child-lock on the control panel and an outdoor reset sensor for improved energy management. Temperature settings span from 104°F to 180°F for space heating and 98°F to 140°F for domestic hot water.
STAR BRITE Premium -100° Boiler System Antifreeze
STAR BRITE Premium -100° Boiler System Antifreeze is a propylene glycol-based formula designed to protect heating and cooling loops from extreme freeze damage. It provides superior heat transfer and burst protection down to -100°F (-73°C) when used at full strength. The product includes corrosion inhibitors to shield internal components, helping maintain efficiency and extend the life of boilers, hydronic systems, and associated equipment in cold climates.
WiseWater 110V Circulation Pump
The WiseWater 110V Circulation Pump provides reliable hot water circulation for boiler and hydronic systems. With 130 W power and three selectable speeds (55/90/130 W), it supports a maximum flow of 13 GPM and a head range up to 24 ft. The design emphasizes quiet operation and energy efficiency, helping to reduce water and energy waste while ensuring quick delivery of hot water to fixtures. It includes standard 1″ NPT connections and simple mounting hardware for straightforward installation.
Waterdrop AP431 AP430SS Whole House Scale Inhibitor
Waterdrop AP431 AP430SS is a whole-house scale inhibitor designed to protect hot water heaters, boilers, and connected plumbing from mineral buildup. The system uses food-grade polyphosphates to inhibit scale formation, supporting energy efficiency and prolonging appliance life. It’s compatible with standard 3/4″ NPT piping and provides a flow rate of up to 10 GPM, helping maintain steady water pressure across the home while reducing maintenance needs.
CosWarm CW3 Central Heating System Cleaner
CosWarm CW3 is a boiler cleaner designed to treat up to 18 radiators and clean boiler, radiator, and pipe systems. It effectively removes rust, debris, scale, and sludge, helping restore heating efficiency and heat transfer. The formula is described as non-acidic and biodegradable, offering a safer option for homes with sensitive occupants and for use in various boiler materials and configurations. Regular use can support improved system performance and quieter operation.
Buying Guide: Key Considerations for a Boiler Heater System
- System compatibility: Match boiler type (gas, condensing, boiler-only vs. combi) with home heating needs and existing hot water requirements. Ensure compatible control features and zone capabilities match your home layout.
- Energy efficiency: Prioritize high-efficiency boilers and smart controls that optimize fuel use and reduce lifecycle costs. Look for outdoor reset, modulation, and high AFUE ratings where available.
- Maintenance and longevity: Consider components that aid maintenance, such as clear filtration, corrosion inhibitors, and scalable cleaning options. Regular flushing and scale management can extend system life.
- Water treatment: Scale inhibitors and antifreeze play a big role in protecting boilers and pipes in areas with hard water or extreme temperatures. Assess climate and water quality to select appropriate products.
- Installation and space: Wall-mounted boilers save space but require proper mounting and ventilation. Check clearances, electrical needs, and service accessibility when planning installation.
- Safety and control: Look for child-locks, outdoor reset sensors, and programmable thermostats. Simple interfaces help reduce user errors and improve comfort management.
- Maintenance access: Choose pumps and cleaners that are easy to access and replace. Three-speed circulation pumps offer flexibility for flow adjustments without major rewiring.
- Cost of ownership: While not pricing here, evaluate upfront costs alongside anticipated energy savings, maintenance intervals, and potential rebates or incentives for high-efficiency systems.
