  Boiler efficiency, hydrogen-ready boilers, and the role of hybrid systems.
  note

  [Quote: "There are around 30 million buildings in the UK responsible for approximately 30% of our emissions. The vast majority (79%) of these emissions result from heating, making up 23% of all UK emissions. As such, meeting net zero will require almost all buildings to fully decarbonise." Quote: "The gap between laboratory tested and in-home efficiency is often because the flow and return temperatures are too high, limiting boilers' potential to condense. This was one of the key issues the original Boiler Plus Standards were aiming to address by encouraging take-up of controls that lower flow temperatures. ... To start to achieve higher efficiencies, the return temperature needs to be equal to or below the 'dew point' temperature of approximately 55°C (the temperature below which the flue gas needs to be cooled, in order to allow the water vapour to condense and additional latent heat contained within it to be captured). However, to achieve the higher efficiencies advertised, boilers need to operate at as low a temperature as possible, below this level of 55°C, for the majority of the year." Quote: "BEIS research found that around 50% of homes have heat emitters adequately sized to provide thermal comfort at a flow temperature of 55°C on an average winter day, with outside temperatures at around 4°C."]
