Condensing Boiler Water Temperature

Condensing Boiler Water Temperature. If you are, you’ll probably not want them to be radiating at the heat of a blast furnace. A return water temperature of 80°f will create the most efficient performance for most condensing boiler systems.

A return water temperature of 80°f will create the most efficient performance for most condensing boiler systems. 10/19/2015 8 knowing what we know now…is We have 4 zones, 3 zones control forced hot water baseboard and the other zone controls radiant floor (concrete slab for our greenhouse, we use a mixing valve to reduce water temp to 130f/54c for floor).

The Sensor Measures The Temperature Of The Water Returning To The Boiler, And Ensures The Right Temperature Is Maintained At All Times.


This is usually fitted on the side of the tank. Similarly, conventional, noncondensing boilers were designed so that variable flow through the heat exchanger was unacceptable. Well for a radiator, the recommended output temperature is 75ºc.

During This Process, The Temperature Of The Flue Gas Is Rapidly Reduced From Around 130℃ To 90℃.


If you work it out manually, 55 degrees centigrade will be halfway which will be number 3 on a dial that has numbers from 1 to 6. Putting that debate aside, for now, we can conclude one thing which is that the flow rate is important. (look at the efficiency curves from any common condensing boiler manufacturer to see this.) put another way, you start gaining efficiency only when your return water temperature is approximately 135°f or lower.

The Water Returns To The Boiler After Travelling Around All Your Radiators (Called ‘The Return’) At 60°C, Having Given Off 20°C To The Room.


Water ‘returns’ to the boiler at 60°c. Some boilers have ‘e’ on the dial which stands for economy. In these older, conventional systems, the standard design was to maintain hot water supply temperatures upwards of 180 to 200 f with hot water return always above 140 f to prevent condensing in the heat exchangers.

Condensing boilers with properly applied temperature reset schedules and the right mix of terminal units should have lower heating hot water supply temperatures and boiler return temperatures below 130°f. Your house being the size that you stated, probably has a heatloss of not more than 30,000 btuh on the coldest day of the year. Water temperature must be lower than dew point in order to condense example a example r example h.

The Maximum Temperature That We Recommend You Set Your Radiator Output To Is 80 °C.


If the return water temperature is low enough, it will cool the heat 1) the fan coil needs high water temps to be effective heating the upper level of the house. We have 4 zones, 3 zones control forced hot water baseboard and the other zone controls radiant floor (concrete slab for our greenhouse, we use a mixing valve to reduce water temp to 130f/54c for floor).
