Alternate Device for Vaporstat
I'm a bit tired of these new Vaporstats that are not accurate, cannot be set low enough, and are not capable of repeatable cycles at a set pressure. In short, they are horrible.
What are you guys using for systems that run very low pressure. Yes, I realize that I still will have to use some sort of approved pressure control for code reasons.
I finally finished the refurbishing of that Richardson system. The lower I set the pressure, the better it ran. Outstanding!
Nothing better than a happy customer that FINALLY has comfort in his house after years of inconsistent heating.
