BASIC CONDENSING THEORY ?
@ July 6, 2010 10:19 AM in BASIC CONDENSING THEORY ?
I HAVE A CLIENT THAT HAS INSTALLED ULTRA HIGH EFFIC 95% TRIANGLE SOLO CONDENSING BOILERS AS PART OF A HYDRO AIR SYSTEM. THEY ALSO HAVE INDIRECT WATER HEATER TO PROVIDE DOMESTIC. AM I CORRECT IN ADVISING THEM THAT THEY WILL NOT ACHIEVE THE DRAMATIC EFFICIENCIES LISTED DUE TO THE NEED TO RUN HOTTER SYSTEM WATER TO THE HOT AIR SIDE AS WELL AS DOMESTIC SIDE WHEN IT CALLS. MY UNDERSTANDING IS AS YOU GET NEAR 130 DEGREE SYSTEM TEMP , YOU CONDENSE VERY LITTLE IF AT ALL. ANY ONE ANSWER THE FOLOWING PLEASE... AM I GENERALLY CORRECT? ARE THERE ANY GENERAL CHARTS AVAILABLE TO SHOW RELATIONSHIP BETWEEN EFFICIENCY AND SYSTEM TEMP AND LASTLY CAN I MAKE GENERAL STATEMENT THAT A SIMPLER 90% CONDENSING GAS BOILER THAT IS 1/2 THE PRICE WILL PROBABLY PROVIDE THE SIMILAR OPERATING COST AS THE 95-99% MODELS IN THIS SITUATION. THANKS
