Or anyone else who knows about indirect water heaters.

We installed radiant heat and an indirect heater to our old boiler around early spring, and ever since our gas bills have been rather high. I mean, astoundingly high.

Our heat’s not even on, and we sometimes pay $178 a month for gas, and it never goes below $100.

I am assuming that something got installed wrong, and that this is causing too much boiler-firing. It’s a complicated system–there are pumps and stuff… my husband knows what everything is, but I look at the whole thing and scratch my head.

The water temp is set low, around 120.

I know it’s ridiculous that we’ve been living with this for about six months. But…

…where do we start with the troubleshooting?
