  • Is a high efficiency, condensing gas boiler the best

    Mar 16, 2020 · Which Boilers are High-Efficiency? Here is a short list of high-efficiency boilers. All burn natural gas, with the exception of those that explicitly state "oil-fired". This is not a comprehensive list — there are many high-efficiency boilers that we have not included. Bosch Greenstar; Burnham Alpine; HTP Elite FT; Laars Mascott II; Lennox GWM-IELearn More

  • High Efficiency Residential Oil Boilers | Energy Kinetics

    Energy Kinetics boilers have over 90 lbs. of insulation and jacketing, virtually eliminating all losses. Common boiler controls and outdoor reset controls are not effective at reducing fuel bills. Energy Kinetics "low mass" boilers are designed with energy recovery and thermal purge controls, creating the best heat and hot water efficiency.Learn More


    Example: Saskatchewan Penitentiary installed two new, smaller boilers, sized for summer load (operating singly) and for joint operation during the winter. They replaced old, oversized boilers, which operated at low fire for most of the year. This solution led to higher efficiency at higher firing rates.Learn More

  • Ray Wohlfarth: Tips for high-efficiency boiler replacement

    Jan 04, 2021 · It was such a simple project; replace the old cast iron boiler with a new condensing boiler. You knocked it out in a few days. Then, the phone calls started. We've all had those projects that both haunted and cost us. The following are some ways to limit those projects. Venting The new condensing boiler will most likely vent through the sidewall of the house.Learn More

  • Squeezing Maximum Efficiency Out of Your Condensing Boilers

    Jun 07, 2021 · Referring to Figure 1, in the efficiency curves for both Figure 4 cases, there is a 2.7% increase in boiler thermal efficiency for the variable primary piping arrangement. Only high-mass boilers can be piped variable primary due to the large water volume and flywheel effect when the load changes and the boiler controls respond.Learn More

  • 15 Ways to Increase Boiler Efficiency in Your Facility

    From Example 8.2, the existing boiler has an excess O 2 of 6% and an overall boiler thermal efficiency of about 78% (i.e., η s t d = 0.78). After the boiler tune-up, the excess O 2 is 3%. Using the monograph of Fig. 8.12, the new boiler efficiency can be determined from the flue gas temperature (343°C or 650°F) and the excess O 2 (3%).Learn More

  • Boilers to go condensing under new efficiency regulations

    Aug 11, 2020 · Under Amendment 15 to Canada's Energy Efficiency Regulations, all boilers must be 90 percent efficient – by Jan. 1, 2023 for residential units and Jan. 1, 2025 for commercial boilers.
