Hello everyone,
Over the past few days, I have been researching the topic of heating systems and sizing, and I keep encountering different approaches. I would like to hear from those who have installed a gas condensing boiler with underfloor heating in their new build about how their system was sized.
The following points are of interest to me:
Supply temperature:
Spacing of the piping:
Individually or more closely spaced pipes in bathrooms and near windows (Yes / No):
Maximum length of heating circuits:
Material of the pipes (PEX / aluminum composite):
For how many square meters was one heating circuit designed? Ideally, the room size in square meters and the number of heating circuits.
A brief practical feedback:
----------------------------------------------------------------------------
Currently, I have received offers assuming supply temperatures of 45°C (113°F), pipe spacing of 15cm (6 inches), no individual adjustments in bathrooms and window areas, and the use of aluminum composite pipes. The heating circuits are supposed to be a maximum of 80 meters (262 feet) long. This seems rather suboptimal compared to my online research.
With a sufficient number of responses, at least a trend might become apparent.
Thank you in advance.
