Removing Kerosene Monitor Heaters: A Step-By-Step Guide

Kerosene monitor heaters are a popular space-heating option, especially in the cold season. They are economical and provide warmth and comfort to living spaces. However, with the discontinuation of Monitor heaters by the Japanese manufacturer, Hitachi, finding repair parts and servicing for these heaters has become challenging. This has left many homeowners wondering about their alternatives when their Monitor heater breaks down or requires maintenance. While some may choose to explore propane or electric alternatives, others may prefer to stick with kerosene-fueled options, such as the Toyotomi heater, which is similar to the Monitor heater in terms of functionality and fuel type.

Troubleshooting a Kerosene Monitor Heater

Kerosene Monitor heaters are no longer being manufactured, and it can be challenging to find repair parts. If your Monitor heater is malfunctioning, there are a few things you can try.

First, check the manufacturer's website for a user manual, which should provide detailed instructions on troubleshooting and resolving common issues. If you're experiencing issues with the heater not staying on, it could be due to overheating or an issue with the thermistor. Refer to the manual to understand the specified temperature sensing range and the corresponding resistance measurements. You can then measure the resistance across the Q connector on the PWB to determine if the thermistor is functioning correctly.

Additionally, pay attention to any knocking sounds or changes in the flame appearance before or while the heater shuts off. These could indicate a problem with the fuel supply or a blockage in the pot, respectively. If the flame rod has come into contact with the flame ring, or if there is soot buildup between the rod and the ring, you may need to adjust or clean the flame rod.

If your Monitor heater has completely stopped working, you may need to consider replacing it with an alternative heating system. There are a few options available, depending on your preferred fuel source: kerosene, propane, or electric. The Toyotomi Toyostove is a popular kerosene-powered alternative, offering energy efficiency and ease of installation. For those already using propane to fuel other appliances, the propane-fueled Empire heater is a reliable and aesthetically pleasing option. Lastly, for those seeking maximum energy efficiency, the Mitsubishi Ductless Split System offers the added benefit of cooling during the summertime and improved air quality through its multiple air filtration system.

Remember, if you're uncomfortable performing any troubleshooting or repair work yourself, it's best to consult a qualified technician to ensure your safety and the proper functioning of your heater.

Kerosene Monitor Heater Replacement Options

Kerosene monitor heaters have been one of the most reliable heat sources, especially in the Piedmont and Mountain regions. However, with the discontinuation of Monitor heaters by the Japanese manufacturer, Hitachi, and the subsequent unavailability of OEM parts, many users are now looking for replacement options.

There are three main replacement options, depending on the fuel source you prefer: kerosene, propane, or electricity.

Option 1: Kerosene Fueled Toyostove

The first option is the Toyotomi Toyostove, a kerosene-powered space heater similar to the Monitor heater. Toyotomi space heaters are energy-efficient and easy to install, requiring no chimney, ductwork, plumbing, or electrical work. They can heat large spaces and are clean, safe, and efficient. They can often be installed in the same location as the old Monitor heater with minimal cosmetic changes.

Option 2: Propane Fueled Heaters

If you want to switch from kerosene to propane, there are a few options available. The Rinnai Ductless Furnace, including the EX22 and EX38 models, is comparable in size, operation, and heat output to kerosene monitor heaters. They can be installed in the exact location as your monitor heater and vented through the existing vent hole, making installation easier and less costly.

Another option is the Empire heater, a wall furnace that uses propane to heat your living space. It is similar in design, aesthetics, and sizing to the Monitor and Toyostove heaters. The Empire heater offers features like auto-shut-off safety controls, manual and hydraulic thermostat controls, and the option to mount it on a wall or floor.

Option 3: Electric Mitsubishi Ductless Split System

The Mitsubishi Ductless Split System is an extremely energy-efficient option that can cool your house in the summer and improve air quality with its multiple air filtration systems. It is quiet, smart, and can detect temperature changes by scanning the room, making any necessary adjustments to ensure your comfort. The installation is quick and mess-free, as it requires no ductwork.

While saying goodbye to your Monitor heater may be difficult, these replacement options offer similar benefits and more, providing safe, energy-efficient, and cost-effective alternatives.

• Kerosene-fuelled Toyostove: This option is very similar to the Monitor heater and is a great choice for those who want to stick with kerosene as their fuel source. The Toyostove is energy-efficient, clean, safe, and runs at peak efficiency. It can be installed in the same location as the old Monitor heater with minimal cosmetic alterations.
• Propane-fuelled Empire Heater: The Empire heater is a wall furnace that uses propane as its fuel source.

Servicing a Kerosene Monitor Heater

Kerosene Monitor heaters have proven to be an effective and economical way to heat living spaces. However, with the discontinuation of the Monitor heater and its parts by the manufacturer, Hitachi, servicing and finding replacement parts for these heaters has become increasingly difficult.

If your Monitor heater is not working, there are a few troubleshooting steps you can take. Firstly, check if the heater is turning on but not igniting, as this could be due to a lack of fuel. Ensure that the fuel tank is topped off, and if the issue persists, try bleeding the air out of the line. You can do this by gently pressing and releasing the Fuel Constant Level Valve Reset Lever a few times, as per the manual.

If you are experiencing issues with your Monitor heater, there are technicians who offer in-shop services and repairs. They can assist with diagnosing and repairing your heater, and provide guidance on ordering the necessary parts. These services are also available for portable kerosene heaters that may require wick replacement.

When removing your Monitor heater for servicing or repair, there are a few important steps to follow. Firstly, turn off the fuel supply at the tank and disconnect the fuel supply connection at the back of the heater, being careful not to twist the copper line. Plug and cap the fuel lines coming into and out of the heater, ensuring you purchase the correct type of cap and plug (flared or compression fittings). If you have a lifter pump, follow the manufacturer's instructions for disconnecting the fuel supply. Additionally, disconnect the small spring on top of the flue pipe before removing the heater, and always keep the heater upright during transportation to avoid any potential damage.

While servicing and repairing Monitor heaters has become challenging due to the unavailability of parts, there are alternative heating options available, such as the Toyostove, Empire Heater, and Mitsubishi ductless split system. These alternatives offer similar functionality and efficiency while also providing the opportunity to explore different fuel sources, such as propane or electricity.
