Does radiant hydronic in floor heating require mixing valves?
We have six zones in our in floor heating, but no mixing valves or thermometers. We have hardwood, tile an carpet in various parts of the house. Currently the water temp under the hardwood is running too high for the wood to bear. We are trying to determine whether we need to have mixing valves installed to make the heating system safe and operable, or if they would just be a "nice to have".
Can I put two hydronic radiators on the same supply and return on two different floors?
I live in a small house with hydronic heat. The original homeowner moved a radiator from the master bedroom to the basement bathroom directly below. All the original piping was used, just diverted downward with tees and vent plugs installed in the upward facing tee outlets.
Can I install another radiator in my master bedroom fed from the same tees? (removing the air vents since the second radiator has them built-in and running pipe back upward) This would mean the same supply and return would feed two radiators on two different floors.
It’s a single zone house. It’s a "monoflow tee" type system with both supplies and returns feeding into the same loop.
Need help sizing a circulation /hydronic pump. Please help!?
Have 75,000 btu boiler, cast iron, with 1" supply and return. Using with a 79 gallon indirect, hot water heater /storage tank. Co. says flow rate for coil is 5gpm . They do not list pressure loss at coil. I am using 1" heat pex for supply and return to HWH. About 12′. What circulator should I use, please? Such as what size, series, Taco,Grundfos, Wilo ?

hot water heating system problem?
Working on solving a hydronic heating problem at a friends new garage. Its a heated slab and the guys that installed the slab, also laid in the PEX tubing and did it very wrong. They were told to keep the loops less than 240′ (1/2" pex) well being given three 500′ rolls they laid in 3 loops 500′ long. Big problem is that my buddy and I were gone that day and the slab was poured and finished when we returned late that night. Each loop will have 51′ head loss at 3 GPM. Any suggestions on salvaging this mess? circ pumps in series? One big pump? trying to solve this for hundreds not thousands.
