For wood burning boiler systems, the right supporting parts depend on the job: a hydronic unit heater distributes heat indoors, water treatment helps address corrosion, and a compatible solenoid serves as a replacement control component. The products below are accessories and parts, not complete boilers. The Alecoil heaters are best for heating garages or workshops connected to a hot-water system; the Crown treatment is intended for system protection; and the HQPASFY solenoids are replacement options for WoodMaster equipment.
| Product | Best For | Key Distinction |
|---|---|---|
| Alecoil 100,000 BTU heater, black | Overhead heating in a garage or workshop | Remote controller and three operating modes |
| Alecoil 100,000 BTU heater, blue | Overhead heating with the same listed functions | Blue finish |
| Crown water treatment | Rust and corrosion protection | One-gallon container |
| HQPASFY solenoid, single | WoodMaster solenoid replacement | One listed 120VAC-coil solenoid |
| HQPASFY solenoid, two-pack | WoodMaster owners seeking two replacements | Two solenoids with the listed replacement design |
Alecoil 100,000 BTU Hydronic Heater, Black
This Alecoil unit is a water-to-air heater intended to work with a hot-water system or wood-burning boiler. It is designed for ceiling installation in spaces such as garages, workshops, farm buildings, and job sites. Its listed capacity is 100,000 BTU, and the product features a 1,500 CFM blower and copper heat-exchanger tubes.
Best for: Owners who already have a suitable hot-water heat source and want to distribute heat in a larger work space without using floor area. The overhead mounting design and included wall-mounted controller distinguish it from a standalone electric space heater.
The controller offers three modes: monitoring water inlet temperature, maintaining room temperature, or using both functions together. The listing says the system adjusts fan speed and water flow. It also specifies a direct line-of-sight remote range of up to 33 feet.
Limitation: This is not a boiler or a self-contained heat source. The remote installation requires a pre-installed power cable at the mounting location, and the listed electrical requirements should be checked before purchase and installation.
Alecoil 100,000 BTU Hydronic Heater, Blue
The blue Alecoil model is another ceiling-mounted water-to-air heater for use with a hot-water system or wood-burning boiler. Its listed specifications and functions match the black version: 100,000 BTU, a 1,500 CFM blower, copper heat-exchanger tubes, and a wall-mounted controller with three operating modes.
Best for: Buyers who want the same described hydronic heating features as the black version and prefer the blue finish. It is intended for garages, workshops, farm buildings, and similar spaces where an overhead heater can preserve floor space.
The product listing describes a galvanized-steel body, a copper coil, and automatic control of fan speed and water flow in response to the selected mode. The controller’s stated line-of-sight range is up to 33 feet. These details make it a possible heat-distribution component for a boiler-based system, rather than a replacement for the boiler itself.
Limitation: The listed remote setup requires a pre-installed power cable at the mounting location. Confirm the heater’s installation requirements and the suitability of the existing hydronic system before choosing it.
Crown Wood Boiler Water Treatment
This one-gallon chemical treatment is described as a rust and corrosion inhibitor for wood boilers and furnaces. The listing says it is suitable for Crown Royal wood boilers and furnaces and is intended to help protect system components and maintain performance.
Best for: Owners of a compatible Crown Royal wood boiler or furnace who are looking for a treatment product specifically described for that equipment. It was selected because system water care is a distinct maintenance need from heat distribution or replacement electrical parts.
The container size is one gallon, which the listing describes as sufficient for standard residential heating systems. However, the supplied product information does not provide a dosing chart, water-volume range, or detailed application instructions.
Limitation: Do not assume this treatment is appropriate for every boiler brand or system. Check the equipment documentation and the treatment label for compatibility, required dosage, and safe handling instructions before use.
HQPASFY 2005-M-1 Wood Boiler Solenoid
This single laminated solenoid is listed as a direct replacement for the 2005-M-1 and as compatible with WoodMaster outdoor wood-burning stove models. The product description specifies a pull-type, continuous-duty design and a 120VAC coil. It also describes a laminated steel body, corrosion-resistant frame, and T-shaped plunger.
Best for: A WoodMaster owner who has identified a need for the listed 2005-M-1 replacement and needs one solenoid. It was selected as a system service part, not as a general-purpose accessory for all wood boilers.
The listing says the plunger and frame are designed for smooth contact to reduce vibration and operating noise. It also describes the part as intended for high-temperature performance, but the supplied information does not provide detailed dimensions or a model-by-model fit chart.
Limitation: Compatibility is stated for WoodMaster models, not every wood boiler brand. Confirm the existing part number, coil voltage, and equipment requirements before ordering or installation.
HQPASFY 2005-M-1 Solenoid, Two-Pack
This listing is a two-pack of HQPASFY 2005-M-1 laminated solenoids. The product information describes the same replacement design and stated compatibility as the single unit: a WoodMaster-compatible part with a 120VAC coil, pull-type continuous operation, laminated steel construction, a corrosion-resistant frame, and a T-shaped plunger.
Best for: WoodMaster owners who need two matching replacement solenoids or want a second unit available for a future service need. The two-pack is easier to distinguish from the single option by quantity; the listed technical details are otherwise similar.
The listing says the design supports continuous duty and is intended to reduce vibration and operational noise through close contact between the frame and plunger. Use the equipment’s service information to determine whether one or two parts are needed.
Limitation: The product data does not establish compatibility with non-WoodMaster systems or provide detailed dimensions. Check the existing solenoid identification and system specifications before purchase.
Buying Guide: How To Choose Wood Burning Boiler System Components
Do you need a boiler, a heater, or a replacement part?
First identify the job. The products listed here are not complete wood-burning boilers. The Alecoil units are hydronic heaters that transfer heat from hot water to room air. The Crown product is a water treatment, while the HQPASFY products are solenoids listed as WoodMaster replacement parts. If you are shopping for a complete boiler, these products do not meet that need.
How should you compare hydronic unit heaters?
Both Alecoil heaters have the same listed 100,000 BTU capacity, 1,500 CFM blower, copper heat-exchanger tubes, and controller functions. The listed difference is the finish: one is black and one is blue. Choose between them based on the finish and verify that the heater suits the space and hot-water system. The listing describes overhead mounting for garages, workshops, farm buildings, and job sites.
Consider installation needs before choosing a ceiling-mounted unit. The product information calls for a pre-installed power cable where the remote is mounted and gives electrical and wire specifications. Review the installation guide and equipment instructions rather than assuming the unit can connect to any existing hydronic setup.
What should you check before buying boiler water treatment?
Start with the boiler or furnace manufacturer’s maintenance guidance. The Crown treatment is specifically described as suitable for Crown Royal wood boilers and furnaces, but the provided details do not establish universal compatibility. Check the label for the recommended amount, system water capacity, application procedure, and handling precautions. Do not select a treatment solely because it is described as a corrosion inhibitor.
How do you confirm a replacement solenoid?
Match the existing part number and electrical requirements to the replacement information. The HQPASFY listings identify the 2005-M-1 design, WoodMaster compatibility, and a 120VAC coil. Confirm those details against the equipment documentation and existing component before ordering. If the part number or voltage does not match, seek the correct component rather than relying on appearance alone.
Should you choose the single solenoid or the two-pack?
The single listing is the straightforward choice when one replacement is needed. The two-pack provides two of the listed solenoids, which may suit a repair requiring two parts or a buyer who needs a matching spare. The product information does not say that both parts must be installed together, so follow the boiler’s service requirements.
What installation and maintenance details matter?
Use the equipment manufacturer’s instructions for system water treatment, hydronic connections, electrical work, and replacement components. Boiler systems involve hot water and electrical controls, so verify that the selected part is appropriate before installation. The product details supplied here do not provide a complete installation procedure or replace professional service guidance.
