In the spring I'll ask the maintenance guy about that.
A good side of lowering the water temperature in our system is that the radiators and pipes won't expand and contract as much (I can hear them creaking and whining shortly after each time the furnace fires up). This may help keep the 40 year old system from springing a leak or two.
On the other hand, with the system at a lower temperature there will be less heat radiating, so I might be forced to raise the thermostat's temperature a bit to stay comfortable. |
do you need a 100W pump? for my solar setup I'm leaning towards something in the 10W or so range. There are tons to choose from.
