Boiler environment control
I was watching an edition of "This Old House" and I saw the installation of a boiler control to hopefully save energy and I was wondering if it would work or work well with my boiler. I have a Weil Mclain VHE6 that I installed in about 1990 that is still going strong. When I say I installed I mean I personally installed so I know a lot about it, not that it is that complicated. It is a single zone two pipe radiator system.
I did a little research and found a Tekmar 256 single stage controller that looks like it would work. I have a number of questions.
Would this type of controller work with my boiler? The boiler has a very low water capacity. I think there is something like 6-8 gallons in the boiler.
If it would work would it be beneficial in cost savings?
Would I leave the circulator run all the time? Mine is the stock Taco that came with the boiler and has been running for 20 years.
Is this model a good choice? Are their others that could also work?
