Is antifreeze necessary for monobloc Daikin Altherma?
Antifreeze can be used in Daikin Altherma Monobloc applications where the site is not occupied or monitored, can be exposed to temperatures below freezing (32F, 0C) for long periods of time or could experience a high occurrence of power outages. Only propylene glycol formulated for hydronic heating can be used. Always remember that adding antifreeze will reduce the output capacity of Daikin Altherma and may require larger expansion tank and circulators. To keep antifreeze mixtures at a minimum, Daikin recommends antifreeze mixtures for burst protection. Refer to installation instructions for propylene glycol mixtures and capacities corrections. Refer to local codes when using antifreeze.
