Unless you have prior electrical experience, it’s best to hire a professional to install your new thermostat for you. Improper installation can damage wiring, lead to a blown fuse, and more.

It can be safe to buy or live in a house with knob and tube (K&T) wiring, but only if the system is in good condition, functional, and has been thoroughly inspected and approved by a licensed electrician. Never purchase a home with K&T wiring without getting a professional electrical inspection first.

Key considerations include:

• Safety and Condition: An inspector will verify that the wiring is safe and has not deteriorated. Over time, the insulation can wear away, leaving exposed wires that pose a significant fire or shock hazard.

• System Capacity: The electrical service should be at least 60 amps. However, even at this capacity, K&T systems often struggle to handle the demands of modern appliances and electronics.

• Lack of Grounding: Knob and tube wiring is an ungrounded system, which is a safety concern for many modern devices.

• Ongoing Maintenance: If you live in a home with K&T wiring, it's recommended to have it inspected by an electrician every one to two years to ensure it remains in safe working order.

Ultimately, any inspection or modification of a knob and tube system should always be performed by a certified professional.

To upgrade electrical systems in older homes, you might need to reroute new wires with lath and plaster walls. That’s because it’s more challenging to get inside the walls of an older home compared to a modern home, which usually uses drywall. But there are easier ways to level up your electrical game in an older home. For instance, you can swap out an old furnace for a new electric heat pump, or you could use a heat pump for water heating.

Circuit breakers can wear out, but it takes a long time. Circuit breakers typically last several decades if they don’t face problems like floods or frequent lightning storms. Worn-out circuit breakers may trip more frequently as time passes. However, they can also stop tripping altogether, which leads to electrical dangers. If your breakers have passed the 30-year mark, it’s time to consider an inspection.
