Recently replaced my central air with a Trane heat pump. I would like to take advantage of the savings the heat pump offers to heat the house and save some fuel oil consumption.
My boiler is hot water radiant base board with pipes in the attic. I would like to run the heat pump with outside temps in the mid 20's or lower but have concerns about the pipes freezing in the attic.
I would like to run the circulating pump on the boiler and the only way I know how to do this is to turn the tstat for the boiler up and lock out the Honeywell R8184 Protectorelay to keep the boiler from firing and the circulation pump running.
Would this cause any harm to the boiler system or be a safety issue?
