Why is the by pass kit necessary when using two heaters?

The pressure could "bust" the heaters. According to the book. But the kit is bogus. Off standard sizes fittings and clamps. I only used the valve. Bought the rest at hardware store. The other advantage is more pressure for cleaning when you bypass completely. Hope that helps.

When the sun is not out, you need to stop water from going through the heaters. It will do the opposite if the sun is not out and cool the water. Hope this helps.

Yes. In fact that was recommended by the electrician who installed it. When you need heat, you need heat. And you always want to be sucking the moisture out of the room. Using both together works perfectly fine for me.

I would suggest 12/2 to wire these units. It's true the unit above only uses less then 10 amp- 240VAC. But using 12-2 allows you to put more than one heater on a circuit. There is only one power connection.

Other. The heater is just enough to take the chill off . But it is not for a large area or primary heat source .

This is just a thermostat. To control two zones you need two thermostats and a device on the furnace. It makes little sense to have a single thermostat which can by definition be in only one place controlling two zones.

When you say "two separate systems" is assume you refer to 2 heating systems. I have 2 separate gas furnaces in my home. I have 2 Z-Wave thermostats, 1 for each furnace and I can control each one independently. Each thermostat is a separate device on my iPhone app. I use ADT security's app. Hope this helps.

Must be purchased separately. You may also wish to connect a thermo switch to activate the heat cable automatically.

no you have to use 3 40 amp breakers. The heater has 3 heating elements which all require their own breaker.

Not sure whether or not they can. Can you provide more details as to what your trying to accomplish by having 2 thermostats.

I don't still have my instructions, but I don't know why anyone would use two. In my opinion a second one would block the heat and not be as effective.

No, you can link multiple sensors to one thermostat but not multiple thermostats to one sensor. You would benifit from having multiple sensors so the average temp is used helping reduce heating/cooling cost and reducing hot and cold areas.

Hi, new guy! One is dedicated intake, one is dedicated output. It makes the entire closed system more efficient. Google AC one hose vs two hose, and you will likely get more educated answers, but I hope mine helps. Two is well worth the money, over time.

yes these are set in series for dual heaters like my own at 230vac if you have 120 vac use only one set temp bout 105 f don't want to scorch your self , but if you go on vacation turn of circuit breaker and shut off water.you just never know..

Yes just be aware of what else maybe drawing off the circuit you are looking to add the heater to. Requests a dedicated circuit.

I don't see why not. I would put them on different time delays for a power failure so they both wouldn't try to call you at the same time. I assume you want two units for temperature monitoring.

You mean the dials to switch the heat on and the other to direct the flow? If so, yes, two dials come with the unit. However, I have had problems with one of the dials falling off all the time--kind of a nuisance. You have to make sure that you don't pull it out at all when you lean over and move the dial.

You can use both at the same time. The left one is more powerful, but the right one is more than just a warmer.
