Review: KEEP SPARES ON HAND - We keep several of these on hand for when they burn out. Easy to install. Gets the boiler up and running in minutes. They are cheap enough that we can have a bunch hanging from the basement rafters, ready to go. They last about 2 heating seasons. Takes about 10 minutes to change. Saves a ton of money by not having to call a boiler repairman!
