  • Sealing Flu going through the ceiling. | PlumbersForums.net

    Leak from roof by vertical flue. I had a conventional boiler changed to a combi a few weeks ago. It uses a vertical flue. The plumber replaced the vertical flue however since I have noticed water coming down from the roof where the flue is onto the boiler. I have contacted the plumber about this (was also contacting him as he hadn't Learn More

  • Leak from roof by Vertical flue - MyBuilder

    Nov 05, 2019 · Boiler flues are fitted when using combi, regular, and system boilers. The only exception that may apply to a small number of homeowners is a back boiler. This is a type of boiler that is fitted behind a fireplace. If you have a gas boiler behind your fire, the emissions will exit through your chimney, rather than via a boiler flue.Learn More

  • Use Feedwater Economizers for Waste Heat Recovery

    Generally, boiler efficiency can be increased by 1% for every 40°F reduction in flue gas temperature. By recovering waste heat, an economizer can often reduce fuel requirements by 5% to 10% and pay for itself in less than 2 years. The table provides examples of the potential for heat recovery. Example An 80% efficient boiler generates 45,000 Learn More

  • New gas boiler regulations | Flue, cupboard, gas pipe & lofts

    Dec 06, 2020 · A vertical flue rises off the top of the boiler and can go through a flat or pitched roof or through the wall at a higher point. Vertical flues have a limit for the number of metres then can travel. Each manufacturer will specify this for each of their boilers. For every bend used in the flue, the maximum length it can travel is reduced by 1m.Learn More

  • Boiler Flues: How do Horizontal & Vertical Flues Work

    The only cases where a property won't have a flue pipe is if it's heated by a back boiler, electric boiler or renewable heating system. And this is for the following reasons: Back boilers are installed in a chimney so the waste gases and steam can be released up and out of the home, without a flue.Learn More

  • Water Handbook - Boiler System Failures | SUEZ

    Straight tube, shell-and-tube waste heat boilers frequently develop tube and tube sheet failures due to the imposition of unequal stresses. A primary cause of this is the uneven distribution of hot gases across the face of the tube sheet. The tubes involved tend to come loose, creating leakage problems.Learn More

  • How do Waste Heat Recovery Boilers Work? – Thermax Ltd

    Feb 27, 2019 · A waste heat recovery system recovers heat with sources with high energy potential such as hot flue gases or steam from cooling towers. These systems help to create new and ultra-efficient renewable energy. Heat recovery systems tap into energy that already exists thereby maximising available energy and reducing the collective impact on the environment, including…Learn More
