radiant floor mixing valve.
My radiant floor heating system does not use a mixing valve in the copper piping before the supply and return go to the header. Most designs i see for sure has this. why is this? does the mixing valve keep the hot water in the system (vs sending it back to the boiler) and just send colder water back to be heated.
Im concerned this is a place for a lot of heat loss or basic inefficency loss..
thanks for any help.
