Condensing boiler or Cast iron?? | Terry Love Plumbing

I had someone came and due a heat loss calculation and basically said i need only a 70,000 btu boiler. what would be the best way to heat my house efficiency? go with a regular cast iron 85% efficiency boiler like a burnham ES2-4 or a condensing modulating boiler or any other boiler so fit.

Lochinvar high limit manual reset - keeps locking out | Page

Above 130F entering water temp there is no condensing with any manufacturer's boiler, and the combustion effiency is no more than ~87%. At the beginning of condensing the combustion efficiency is about 88-89%, but rises quickly as the entering water temperatures fall.

Lochinvar Condensing Boiler Efficiency Curve

2017-6-16·Figure 1 below shows a typical condensing boiler efficiency curve from a manufacture and a theoretical performance curve. Figure 1 Typical Condensing Boiler Efficiency Curves The boiler starts to condense water out of the combustion gasses when the dewpoint of the combustion gasses is reached; which, at sea level, is about 130˚F (54

High efficiency boiler recommendations | Terry Love Plumbing

Nov 14, 2018 · It's shocking how many modulating condensing boilers get installed where the installer programs it for 180F, no reset curve, and just walks away. To get any condensing efficiency out of it requires the boiler run at 130F or lower as much as possible, but whether it can be run there without short-cycling depends on your zone radiation.

Best Efficiency: Multiple Condensing Boilers Heating Help

AERCO point to the "Inverse Efficiency Curve" of condensing boilers - that is, unlike atmospheric boilers, condensing boilers are slightly more efficient at low load than they are at high load. So it is more efficient to have multiple condensing boilers all running and sharing the load than to have some running at 100% and the other boilers shutdown.

Monitoring energy efficiency of condensing boilers via hybrid

By using real-world boiler efficiency data we show that the proposed approach results in a (dynamic) nonlinear efficiency curve which gives a more complete description of the condensing boilers operation than static nonlinear efficiency curves: in addition, the dynamic curve can be derived a priori, i.e. from first principles, or from
