What Is The BEST Water Heater Temperature Settin

Jan 13, 2020· Gas and electric water heater temperatures are set at the factory, but can be adjusted for your own preferences with only a couple of tools. If you have already set the temperature and are saying to yourself, “I have no hot water” or not enough of it, there are a few factors that may be affecting the heat. If all else fails, the heating element may be failing, and needs to be replaced.

What temp do most people set their boilers

Dec 01, 2015· It's not that the boilers condense for longer when the return temperature is about 55C but that condensing will only happen if the return temperature is below 55C. How much condensing occurs is related to the flow temperature - the lower it is the more heat is extracted from the water …

Specifying high-temperature hot-water boilers and syste

File Size: 800KB High-temperature hot-water (HTHW) plants are typically designed to operate at temperatures ranging from 350°F to 420°F. The system pressure must be at least 25 psig above the saturation pressure of the high-temperature water’s maximum temperature to prevent pump cavitation and flashing of superheated water …

What is the Most Efficient Temperature to Keep the Boiler A

May 28, 2013· If you set it too high, as is possible if you use the first method and put the heating on full with an idea to turning it off soon after, the risk is that the water which returns to the condensing boiler after having circulated through the radiators will be too high a temperature to recover enough heat from the boiler’s exhaust gases.

What temperature should a condensing boiler be set

Most modern boilers will have a digital dial that allows you to set the output temperature. For combi boilers, the recommended output temperature for the radiators is 75 °C and for the water it’s 60 °C. You shouldn’t need to adjust these output temperatures as you may alter the boiler’s efficiency.

RTC (Return Temperature Control) - Burnham Commercial Boile

The Burnham Commercial Return Temperature Control (RTC) provides an economical and effective means of boiler protection from thermal shock and sustained condensing operation. The RTC monitors the boiler return water temperature and operates a 3-way diverting valve and boiler circulator to maintain a minimum return temperature of 135ºF or greater.
