Automating Steam Boiler in Brooklyn Brownstone

[Robyn Henderson]

My family owns a 3-unit brownstone that has a boiler that is at least 60 years old. On a weekly basis, the first floor tenant checks the water sight to ensure there is enough water in the system and also flushes the system to prevent rust accumulation. The tenant has to empty a bucket of water each time. 

I just learned that the tenant has been doing this for years and if he ever forgets, the system will need a costly repair. 

Are there any other Brooklyn Brownstone owners who had a similar issue? Are there modern boilers that can automate this? How much would they cost (including installation)? 

I don't like having a dependency on a tenant to maintain a vital part of the building.
