Hot Water Boilers and Controls - Ashrae Bi-Sta

2016-10-10 · By condensing this water and lowering the stack temperature, 98% efficiency can be reached. Some heat pump supplement boilers can achieve this. A 1 million BTU/hr boiler will produce 6 gallons/hr liquid water when fully condensing This water will only condense at gas temp <135ºF No manufacturer's boiler can take full advantage

2008-3-14 · Hi forget the pipe which is a safety discharge pipe and nothing will be coming out of it except in a fault condition, you should be lookig at getting the flue extended to where it won't condense on the underside of the walkway or see if the manufacturers do a plume kit for your boiler.

Guide to the Condensing Boiler Installation Assessmen

2017-4-12 · boiler is expected to be difficult, an assessment should be carried out to see if a non-condensing boiler may be considered to meet the guidance given in the SBSA Technical Handbook Domestic. In this case a correctly completed form (set out in Appendix A of this guide) is used to show whether or not exceptional circumstances apply.

Condensing boiler - Wikiped

2019-10-15 · One of the hot gases produced in the combustion process is water vapour (steam), which arises from burning the hydrogen content of the fuel. A condensing boiler extracts additional heat from the waste gases by condensing this water vapour to liquid water, thus recovering its latent heat of vaporization. A typical increase of efficiency can be
