Runtal Radiator Placement Review/Advice
Attached is my planned layout for the runtal radiators in my upstairs living area. I am hoping some of you guys might get a second set of eyes on this layout and point out any mistakes or provide some advise for a first timer. All the radiators are Runtal, and each will be controlled with a TRV and piped via a home-run system. I found that a SWT of 150*F to the radiators is the best compromise for radiator size.
The heat-loss calc was performed by a PE with a design day of 29*F, he came up with 27,537btu for my 1,248 sq/ft house, or 22btu/sq.ft. I plan on installing a Lochinvar Knight KHN055 modcon boiler, a 50 gallon indirect water heater set up to be priority heated, and an 18 gallon buffer tank to deal with the small heating zones. I will circulate the heating water in this system using a delta p variable speed pump controlled by the logic of the boiler. Thanks for any advice.
