How much heat are you losing by having 58 pex for main line to the baseboard?

IT IS NOT SO MUCH HOW MUCH HEAT YOU ARE LOSING, BUT THE PUMP REQUIRED TO OVERCOME THE FRICTION LOSS OF THE 5/8" PEX AND FITTINGS. NOMINAL BASEBOARD HEAT OUTPUT FOR RESIDENTIAL 3/4" CU IS 500 BTUH PER LINEAL FOOT AT 180 DEG. H20 ENTERING TEMPERATURE WITH A 10 DEGREE TEMP DROP. CALCULATIONS FOR MAX. VELOCITY NOT SO MUCH FOR THE PEX, BUT FOR THE FITTINGS ARE NEEDED. THE MINERALS IN THE H2O WILL CAUSE PREMATURE FAILURE OF THE FITTINGS AT HIGH FLOW RATES. SHORT ANSWER IS MOST LIKELY TO INCREASE THE SUPPLY TEMP AT LOWER OUTSIDE AIR TEMPS, TO COMPENSATE FOR LOWER FLOW RATES. lc

Is a circulating pump located on the supply or the return line in hot water heating systems'?
It can be in either location, depending on your head pressure ie a circ on the head or "pump away" will circulate water better in upper floors. If the system is in a 2 or 3 story house using standard baseboard, then having the circulator in either position wont matter. Most all manufacturers are shipping and or directing installers to pump away...circulator on the supply....
What are the dangers from hitting a power line while digging?
When digging it's possible to hit an underground power line. Hitting an underground power line can be very dangerous and is similar to having contact with an overhead line.
What is the purpose of having a low impedance for transmission lines?
in order to reduce the transmission line losses we need low impedance...Low impedance also improves power transfer capacity of the line..
What happens if one leg in a 3 phase synchronous motor fails does it reverse its rotation?
No it does not reverse rotation. If the proper motor protection is used on the motor, the motor should trip off line. Loosing a leg will drive the other two legs of the motor into a higher than normal state. This higher current will be sensed by the overload protection and the motor contactor will drop out. This opening of the motor contactor will drop the supply to the motor and the motor will stop.To reverse a three phase motor, reverse any two feed wires to the motor. This is usually done at the motor's junction box to preserve the wire colour coding of the wires through out the system.AnswerDo you really mean a 'phase' or do you mean a 'line'? This is an example of where the use of correct terminology is important. 'Losing a phase' means losing one of the machine's three field windings, whereas 'losing a line' means losing one of the three supply conductors. Two completely different situations for a delta-connected machine.For example, for delta-connected field windings, the three-phase supply is maintained and the machine assumes an 'open delta' condition, whereas losing a line places two windings in series and in parallel with the third, across a single-phase supply.
How do you set up a megger to test insulation resistance on self regulating heat tracing?
One lead will go on the braided shield (this is essentially the ground), the other lead goes on the heating conductors. Megger either one lead at a time, or both conductors under the same lead. I usually test at 1000v - follow manufacture's spec if unsure. You cannot test line to line with a megger. Testing line to line with an ohmmeter is of some use, as the ohmic value will be dependent on the length, wattage and, to some degree, the temperature of the heat trace. This test is most useful with more than one run of identical heat trace, or to track one piece over time. Values far outside of what is expected will indicate damaged (open or shorted) heat trace.
Is half inch water line sufficient for water supply for forced hot water baseboard heat?
Yes, 1/2 inch supply to fill boiler will work fine. Piping going to baseboard heaters needs to be sized properly. 1/2 inch piping to baseboard heaters not recommended. Most hot water baseboard heaters piped with 3/4 pipe.
What are some manufacturers of baseboard heating systems?
Baseboard heating systems are manufactured by a variety of different companies. Qmark, Cadet, and Homebasix, for example, each have a line of these products.
What is the line where the ceiling meets the wall called?
The line where the ceiling meets the wall is called a cornice. A cornice can be set off from the ceiling with the use of cornice trim. The line where the wall meets the floor is called a baseboard.
How do I determine the voltage of the wall thermostat for an electric baseboard heater.?
There are two different types of thermostats for electric baseboard heaters. Line voltage and low voltage. Connection to a line stat used the source voltage from the distribution panel and operates like a switch. Because the baseboard heater usually is 240 volts the stat breaks both hot inputs. The stat output goes to the baseboard heater. When the stat calls for heat its internal switch closes and applied the 240 volt to the heater. On the side of the stat will be a voltage and current rating that the stat must operate within. The other type of thermostat is used in low voltage installations. Instead of the switch being in the wall like a line stat, there is a low voltage relay mounted in the baseboard heater itself. This relays coil is usually 24 volts AC. An external 24 volt transformer is needed to supply a voltage to this coil. This 24 volt supply is first taken to the low volt stat and an internal low voltage switch is used to energise the coil of the relay in the baseboard heater. The difference between the two stats is very noticeable in that the line stat is very heavily built with strong termination points. The 24 volt stat is very flimsy in comparison as the current it has to handle is only the relay coils current.
What do you call the line where a wall meets the floor and where that wall meets the ceiling?
The piece of wood that goes in between the floor and wall is called a baseboard.
What is the function of steam engine?
The function of the steam engine is to convert heat energy into motive power, mechanical energy. A boiler generates steam by the application of heat, that steam is then expanded (losing its heat energy) into a steam engine which moves a load (locomotive, line shaft, pump, machine, generator, etc.).
What is the slope of a line having no steepness?
A straight horizontal line is a line having no steepness.
What process is involved for installing a 240V line in a house that needs to run about 35 feet for baseboard heating.?
It would be best to call a qualified electrician to install the wiring.
Where can you find thermostat for an electric baseboard heater HPH15002E?
any hvac supply store (Grainger) ask for a line voltage stat, they have many styles but they are all the basic same
What is the mosquito line?
the mosquito line is a line of heat that constricts the mosquitoes in one place
If a baseboard heater has its own thermostat can you bypass it and wire it to a wall mounted thermostat?
Yes, but be sure you buy what is known as a `line voltage thermostat`when you do this since you have no control voltage but are simply breaking a line in the main power feed to turn the strip on and off.
