Just throwing this out there 300 ft on 1/2 pex as I know is the limits on 1/2 pex unless you would like to buy a large pump and a large td on loops and issues balancing . General rule is more loops and keep the loop lengths at or with in 10 % of each other . Also be sure to buy quality manifold w decent flow indicators ,cheap on line manifolds are just that and replacing later is always more costly then spending once and getting it right . As a pet peeve be sure to include a manual hi limit on your radiant loop nothing worse then a bad mixing valve and a floor over heating and ruining say a hardwood floor who pays the bill ? I know it’s not seen much these days but ions ago they were usually included in a radiant system design and boiler diagrams but neither are rarely seen and when it does happen nobody takes any responsibility . Even on a mod con w mix temps I feel it’s wise to install in a last ditch effort to prevent an even worse issue from occurring and ending up in court . Just a clam pet peeve secondary back up or first line defense for damaging flooring or title on radiant jobs after you have witnessed it you always remember it and keep it in the bag of tricks . Ps I kinda prefer brass Manifolds over plastic and if zoning your radiant take a look at cross mainifolds the flow through them is decent for a radiant system and as for zoning if it’s all one temp it’s a no brainer . A learning curve on piping them and making it all look acceptable but the price point leave everybody else out ta bussiness . Great product for a job that fits the bill but hi gpm over 2.5 then ya gotta look else where for higher flow .
Peace and good luck clammy
