Benefits. Protection Against Thermal Shock and Flue Gas Condensation; Simple Self-Diagnostic Test; Maintains Safe Minimum Return Water Temperature; Adjustable Boiler NEW Burnham 80160916 boiler return temp control in Business Industrial, Industrial Supply MRO, HVAC | eBay Boiler efficiency is driven by return water temperature as well as the boiler load. The return water temperature for non-condensing boilers must be between 130[degrees


RTC (Return Temperature Control)


Clearly the only way to get expected efficiencies from a condensing boiler is to deliver lower return water temperatures than are appropriate for conventional boilers. Basic information on techniques to maximize the seasonal energy performance of condensing boilers will be discussed, including reducing return water temperature, using Domestic Condensing Boilers; Roy Dowling 14 Oct 06 at 10:45: Condensing boilers operate at their best efficiencies with low return water temperatures.

Why Cast Iron Boilers Leak – Heat Loss calculation


I know there is a way to control it with mixing valve for example etc, but why some manufact. do not have any provisions/mention it in their manuals? The RTC Return Temperature Control provides an economical means of boiler protection from thermal shock and sustained condensing operation, says the company. The For the condensing boiler's heat exchanger to extract all the heat effectively, the system has to run with the lowest possible return water temperatures, preferably not

Return Temperature Sensor for CHG, Freedom Boilers


I am about to replace our 1960's thorn M gas boiler. I have been reading books, FAQ's, previous posts but still have one or two outstanding questions. Ideal for use with Copper-Fin, Copper-Fin II, Power-Fin and Solution Boilers When designing a boiler system with return water temperatures below 130°F it is necessary to CONDENSATE RETURN PIPES, PUMPS, STEAM DIAGNOSE FIX BOILER DRAFT HOODS – gas This type of pressure relief device may not sense boiler temperature, just boiler pressure.

Boiler Control protects against thermal shock., Burnham Corp.


One reason for an efficiency drop is because the design and/or implementation of the heating system gives return water (heat transfer fluid) temperatures at the boiler of This works best with p/s and the boiler as a secondary. The sensor is measuring the return water temperature and controlling the flow through the boiler dependent on that GV90+ gas-fired water boiler — Boiler Manual Figure 25 Auto return temp regulation — circulator zoning Piping snow melt systems or combination

High return temperature on condensing boiler CH – DIYbanter


Hi, My boiler shows the return temperature of the CH on its display. Earlier today it was showing 75(C) which seems very hot. As it is a condensing operate with inlet and outlet temperature differentials of up to 40.F, and perhaps a little higher with proper return condition control.

If yes, running it with the RETURN water under 130F would probably destroy it over time let alone outlet temp of 130F. The user's manual says that the GCM (the units controller) mixes return water (cooled by the floor) and by-passed boiler output to maintain 140F temperature into the boiler
