Annex 6.E Determining seasonal boiler efficiency - …

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.

2019-6-13 · However, these figures are for gross calorific values, and a typical "A" rated condensing oil boiler achieving 95% efficiency would be responsible for around 5% more CO2 in use. Equivalent gas condensing boilers are a little less efficient, reducing the carbon penalty for oil systems to less than 10% compared to LPG and around 20% for mains gas.

2019-6-14 · Efficiency. Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.

The ErP Directive has effectively eliminated most high efficiency non-condensing boilers up to 400kW, from being placed on the market by boiler manufacturers and importers. This was a massive shake-up for the industry, with seasonal efficiency bands tightened for both new build and existing buildings.

Oil-fired condensing boiler technology therefore achieves the highest efficiency and very minimum emissions along with the lowest fuel consumption. It is important to know that to get your oil condensing boiler to work at its maximum efficiency, you need your return water temperature to be under 47C , which is the “dew point temperature
