The seasonal efficiency data sheets below have details of product compliance with Building Regulations Part L. All products have to meet certain seasonal efficiency criteria to comply with Building Regulations Part L. The seasonal efficiency data sheets below provide details of boiler efficiency ratings and water heater efficiency ratings.
2014-9-30 · To convert from net efficiency to gross, multiply the net calorific value for the boiler efficiency by the conversion factor for the appropriate fuel, e.g. a LPG boiler 80% net efficiency x 0.921 = 73.68% gross efficiency.. The boiler efficiencies, measured at 100% load and at 30%, are used as the basis for calculating the seasonal boiler efficiency as described by equation 1 below.
2019-5-11 · Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted. This condensed vapour leaves the system in liquid form, via a
Table 4a: Heating system seasonal efficiency (space and …
2007-10-3 · Table 4a: Heating system seasonal efficiency (space and water) 1. The table shows space heating efficiency. The same efficiency applies for water heating when hot water is supplied from a boiler system. 2. For independent water heaters see section at the end of table. 3. ‘Heating type’ refers to the appropriate column in Table 8. 4.
When shopping for high-efficiency furnaces and boilers, look for the ENERGY STAR® label. If you live in a cold climate, it usually makes sense to invest in the highest-efficiency system. In milder climates with lower annual heating costs, the extra investment required to go from 80% to 90% to 95% efficiency may be hard to justify.
2016-11-15 · c) The comparative hot water efficiency is a general indicator of efficiency for boilers; it is not used for SAP calculations.1 In the calculation method the data are converted, if necessary, to gross efficiency under test conditions, and then converted to a seasonal efficiency value that applies under
1979-3-21 · ENERGY STAR Most Efficient 2019 — Boilers. Alpine™ is a natural or LP gas-fired condensing water boiler with a stainless steel heat exchanger. Equipped with the Sage2.1™ boiler control system supporting multiple firing rates, the boiler also features outdoor reset and a touchscreen interface. Class-leading high efficiency boiler
Seasonal Efficiency — Reliability — Longevity — Fast ROI

As with all AERCO gas-fired products, the units deliver superior turndown for a range of noncycling operating range using a variety of return water temperatures and system designs. Until comprehensive, independently
Energy efficiency in hospitals: condensing gas boilers - …
2016-2-9 · gas-fired condensing boiler rated at 17E196 kW was installed to provide the base load space heating requirements. Any further demand is supplied by an Atlantic Optimagaz E232 gas-fired, high efficiency, non-condensing boiier rated at 230 kW. Domestic hot water is provided by two separate gas-fired storage water heaters rated at 105 kW each.
Gas Boilers as Domestic Heating & Hot Water System
Gas boiler heating system’s high reliability, high efficiency and smooth operation made it a very popular market available option. The gas boiler operation principles are simple: gas gets burnt in order to boil the water, which is later can be utilized for different domestic heating or hot water purposes.
