Dan Holohan: Heating Help

RSS

I’ve learned there are many imaginative contractors in the heating business, and many have a fine way with words.

I’ve been thinking about the tens of thousands of contractors I’ve met in my travels since 1970.

A young person asked me a question about a troublesome steam-heating system

The boiler-feed pump, which we also had sold, was overflowing and the contractor had a telephone, so he used it.

A few issues ago I wrote about the chaos caused by installing motorized zone valves in older steam-heating systems found in places of worship.
