Condensing boilers | Jeremias Group - chimney systems

Energy efficient and environmentally friendly. The exhaust gas in the condensing boilers cannot escape through the natural chimney draft. Therefore a blower pushes the exhaust gas through the pipes with a maximum pressure of 200 Pascal. The exhaust pope must be such that it is suitable for over pressure and at the same time not let

Condensing boiler - Wikipedia

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.

Condensing Water Boilers - KEIL Heating and A/C

Natural Gas/LP, Condensing, Hot Water Boilers. A hot water boiler is an appliance used to heat water for a hydronic heating system. The hot water is distributed through the home in pipes into the rooms with either a steel radiator (newer homes) or cast iron radiator (older homes) or baseboard convectors or "fin-tube"(newer homes).

Condensing boilers achieve a much higher efficiency | Vaillant

How a gas condensing boiler functions. In a gas-fired condensing boiler, the water is heated through the heat of combustion, just as with non-condensing boilers. The resulting flue gases are normally passed into the chimney. As a result, the energy contained in the flue gas is lost.
