Based on our extensive experience of installations with diverse and unusual requirements, we recommend close attention to these elements to achieve good outcomes.
Water Temperature – typically 35°C to 55°C for underfloor heating systems, with a difference of 5°C to 20°C between flow and return. With a mixing manifold, low pressure supply water may be up to 82°C.
Individual Room Temperature Control – Avoids conflicts.
Night Setback of 4°C – ensures responsiveness and fabric preservation.
Zone Control – to ensure that timings suit the usage pattern, which may differ zone-to-zone.
Supplementary Heating – may be necessary where there are floor space constraints or unusually high levels of demand; may form part of the installation.
Ventilation – forced ventilation systems should incorporate recovery or make-up air heating to avoid exceeding the designed demand for the underfloor heating system. Other ventilation such as open internal doorways requires careful consideration
Layout of Heating Pipework – care must be taken to avoid hot spots which may damage floor conditions, and vary the water temperature to suit.
Solar Gain –South facing windows will lower the demand in their vicinity.
Floor Finishes and Coverings – these have a major impact on the output available from a given system.
These are the more common aspects for consideration but each installation is unique and our extensive experience will be used to find the best solutions for each project.
