23/03/2021 · Thus, in order to ensure efficient heating for this houses area (L-12 m, W-6,5 m) with the ceiling height of 3.2 m, one will need a boiler or a heat pump with a thermal output of around 13 kWh.
The dew point temperature is a measurement that determines the humidity of air and is the temperature at which water droplets form in the heat exchanger. For gas boilers, the dew point is around 55 °C. This means that the water needs to be 55 °C or lower for your boiler to maintain its efficiency.

13/03/2016 · Hi John, it takes the same amount of energy to heat water from 48 degrees to 52 degrees as it takes to heat water from 58 degrees to 62. But when the state of water changes from solid to fluid (e.g. -2°C to + 2°C) or from fluid to gas (e.g. 98°C to 102°C) this does not hold true any more.
09/03/2021 · A regular boiler is more efficient than a combi at producing hot water, but it will lose some heat from the hot water cylinder. Therefore, a combi boiler may be more efficient overall. Combi boiler. A combi (or combination) boiler provides hot water directly, whenever it is required, and does not need a hot water cylinder.
