I work as an energy auditor, and I often recommend outdoor reset controls for my boiler customers. However, quite a few of my customers are 'snowbirds' who winter in FL or some other warm state.
I realize the payback for an outdoor reset would be longer in a home where the temperature is turned down to 50-55 for the winter. What I don't know is whether the performance of an outdoor reset would be compromised to the point where it wouldn't be worth the cost of installation. I would imagine the control is designed to work most efficiently at normal operating temperatures (65-70). Can anyone speak to this, please?
Thanks. Our program sponsor is handing out a $100 rebate and the GasNetworks is offering $200, so I think I'll be able to sell them. I'll just have to explain it'll be a longer payback and let them decide.
