Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour Review

Let’s Dive into Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour

The Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour is a compact, efficient, and electrically powered solution for hydronic heating systems. Manufactured by Thermolec, this boiler offers a vent-free and gas-line-free alternative, making it suitable for a wide range of applications from new constructions to retrofit projects. The integrated modulation and outdoor reset features promise energy savings and consistent comfort.

My journey to finding this boiler began with a nagging problem: my existing propane-fired boiler was proving to be both expensive and unreliable, especially during peak winter months. I was searching for a dependable, cost-effective, and space-saving heating solution for a small cabin I use seasonally in a remote location. I was particularly drawn to the electric boiler option because the cabin already had reliable electrical service from a nearby solar array.

My first impression upon unboxing the Thermolec boiler was its surprisingly compact size and solid build quality. The unit felt robust, with clearly labeled connections and a well-organized internal layout. Compared to a similar sized gas boiler, the lack of venting requirements immediately stood out as a significant advantage.

I had considered a competitor’s electric boiler, the Electro-Boiler EB-9, and a small propane-fired boiler from Bosch. I chose the Thermolec for a few key reasons: the Thermolec offered outdoor reset, which the EB-9 lacked, and the Bosch unit would require propane delivery to a remote location, adding significant logistical challenges. It seemed to offer the best blend of features, efficiency, and ease of installation.

Initially, I was cautiously optimistic about the Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour. Electric boilers have a reputation for being expensive to operate, but the modulation and outdoor reset features gave me hope for improved energy efficiency. The simplicity of the design was also a welcome change from the complexity of traditional gas boilers.

Real-World Testing: Putting Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour to the Test

First Use Experience

I installed the Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour in my remote cabin’s utility room, connecting it to an existing network of radiant floor heating loops. The installation process was straightforward, requiring only basic plumbing and electrical skills. I performed the initial testing during late fall, with temperatures ranging from 20°F to 40°F.

The boiler performed admirably in these conditions, quickly bringing the cabin to a comfortable temperature. The radiant floor system responded well, providing even heat throughout the space. I appreciated the intuitive control panel, which allowed me to easily adjust the target temperature and monitor the boiler’s operation.

There were no significant issues during the initial testing phase. One minor surprise was the boiler’s relatively quiet operation; it was significantly quieter than my old propane boiler.

Extended Use & Reliability

After six months of seasonal use, the Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour has proven to be a reliable and efficient heating solution. There are no signs of wear and tear on the unit itself. The paint and finish still look new, and all components are functioning as expected.

Maintenance has been minimal, primarily involving periodic inspections to ensure all connections are secure and the system pressure is within the recommended range. Cleaning is simple, involving only dusting the exterior. So far, it has exceeded my expectations in terms of both performance and ease of use.

Compared to my previous propane boiler, the Thermolec offers significantly more consistent heating and requires far less maintenance. The propane boiler needed annual servicing and was prone to breakdowns, especially during cold snaps.

Breaking Down the Features of Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour

Specifications

• Heating Capacity: 9 kW / 30,708 BTU/Hour. This capacity is suitable for smaller homes, cabins, or zones within larger heating systems.
• Voltage: Requires proper voltage based on your region (typically 240V in North America). Confirm voltage requirements before purchasing.
• Amperage: 37.5 Amps. This is important for determining the required breaker size.
• Breaker Requirements: 1 @ 50A. Dedicated circuit is a MUST for safe operation.
• Aquastat Control: Adjustable up to 190°F. This sets the maximum water temperature within the heating system.
• Modulation: Fully Modulating. This allows the boiler to adjust its output based on demand, improving efficiency.
• Connections: Thermostat or zone valve end switch connections. This allows for integration with existing or new control systems.
• Pump Switching Relay: Built-in. Simplifies wiring of the circulating pump.
• Load Management Control Connections: Built-in. Useful for managing power consumption during peak demand periods.
• Outdoor Reset Control: Included. Adjusts water temperature based on outdoor temperature, further enhancing efficiency.
• Safety Features: Built-in circuit breaker, 30 PSI pressure relief valve, and temperature and pressure gauge. Provides multiple layers of protection.
• Dimensions: Compact footprint (check manufacturer’s website for precise measurements). Makes it suitable for tight spaces.

These specifications are critical because they directly impact the boiler’s performance, safety, and ease of integration into a heating system. The modulation and outdoor reset features are particularly important for optimizing energy efficiency and maintaining consistent comfort. The built-in safety features provide peace of mind, while the various connection options allow for flexible installation and control.

Performance & Functionality

The Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour excels at its primary function: providing reliable and consistent heat. It is accurate, quickly responding to changes in thermostat settings. Its operation is mostly silent.

The modulation feature works seamlessly, adjusting the boiler’s output to match the heating demand and preventing wasteful overshooting. The outdoor reset function further optimizes efficiency by lowering the water temperature during milder weather. However, the 9 kW output might be insufficient for larger, poorly insulated homes in extremely cold climates.

Overall, the Thermolec meets and exceeds my expectations for a compact electric boiler. The modulation and outdoor reset features set it apart from many competing models.

Design & Ergonomics

The build quality of the Thermolec is impressive, with high-quality materials and a well-thought-out design. Its weight is manageable, facilitating easy installation and maintenance. The unit is easy to handle, with clear labeling of all connections.

The design is user-friendly, with an intuitive control panel and readily accessible components. The learning curve is minimal; most users can easily understand and adjust the boiler’s settings.

Durability & Maintenance

Based on my experience so far, I expect the Thermolec Tmb Model Electric Boiler With Modulation And Outdoor Reset 9 Kw / 30 708 Btu/Hour to last for many years with proper maintenance. The absence of combustion components eliminates many of the maintenance issues associated with gas or oil boilers. The internal components appear to be robust and well-protected.

Maintenance is straightforward, primarily involving periodic inspections and cleaning. Repair, should it be necessary, should be relatively simple given the straightforward design and readily available parts.

Accessories and Customization Options

The Thermolec comes with essential accessories, including a built-in circuit breaker, pressure relief valve, and temperature/pressure gauge. It integrates seamlessly with various thermostat options and zone valve end switches.
