  • Getting the Most Out of Your Commercial Condensing Boiler

    What temperature should a Vaillant boiler be set at? Your boiler controls explained. To maximise efficiency, we recommend setting your radiator dial to 75 degrees and your hot water to 60 degrees. Once you've got your boiler running at the optimal temperature, you'll want to set the timer for when you need heating the most. With a combi boiler, hot water is on demand.Learn More

  • Ideal water temperature for baseboard heat

    Oct 22, 2011 · If you use a heat-purging boiler control such as the Intellicon 3250 or it's cousin the Beckett Heat manager, the savings are similar to using "outdoor reset" type controls on a high-mass cast iron boiler, in part because the average temp of the water is lower, and the boiler is "parked" at a lower temp during standby, for lower standby losses.Learn More

  • WOAH! Is that hot water boiler sized properly? | US Boiler

    Jul 21, 2019 · Proper hot water boiler sizing Efficient boiler operation is all about run times. The shorter the cycle the less efficient the boiler becomes as standby losses increase. We don't want to heat the system water too quickly. Smaller inputs and slower temperature changes are key to greater comfort and higher efficiencies.Learn More

  • Water Handbook - Preboiler & Industrial Boiler Corrosion

    Hot water boilers heat and circulate water at approximately 200°F. Steam heating boilers are used to generate steam at low pressures, such as 15 psig. Generally, these two basic heating systems are treated as closed systems, because makeup requirements are usually very low. High-temperature hot water boilers operate at pressures of up to 500 Learn More

  • Boiler stuck in standby - DoItYourself.com Community Forums

    Water from the boiler is injected into the radiator circuit at a rate designed to precisely maintain the radiator temperature relative to the outdoors. It can vary from 70 degrees (room temperature) up to 180F if you need it. The boiler is maintained at a different scale, the 180 to 140 range because you have to. Oh well.Learn More
