electric water heater for space heating

The Kid_2

Here's what i'd liked to do... Let me know if any of you guys have done something similiar...

Two kickspace heaters....sized at 160 input water temp.
6 gallons per minute with a 20 degree diff.

looking for a electric water heater to use,
how many gallons should it be.
all the info from the specs that i have base all there water heaters for a 90 rise and output temp of 155 or 120.
residential water heaters are max at 160 degrees.

both manfacture that we normally deal with can not give me a total gph rating....

thanks for any insight..

from the 6 gpm @ 20 delta t, I am assuming 60,000 btuh each unit? 1 Kilowatt = 3,412 btuh. So, 120,000 btuh/3412 = 35.17 kWH. I don't care anything about gallons of storage, because once the circulator has depleted the volume of water (meaning 40 gallon water heater with 12 gpm circulator will drop the water temp 20 degrees every 3.33 minutes)

After that you need the KwH to meet btu load.

Hope that helps.

Electro industries has some nice electric boilers. You want to check out the cost of electric. Remember 1 kWH = 3,412 btuh.

i agree with 60,000btu,

BUT at 35kwh, here would be $4.20/hr running, or $3,025.oo/month electric bill. also around 160 amps/hr.

so, i gather some of the info is way off?

maybe thats max load on the units?

hr

What is the load?

I'm not sure a kick space heater is the best way to move 120K. They are mainly for one room applications, not much fan power.

If you really need 120K and 160 temperatures a small electric boiler would be better than a HW tank. I like the Thermolec.com brand.

Agree on the Thermolec....

...hot rod, I just installed my first one recently. Nice little boiler, and looks to be extremely easy to service.

My only complaint is the lack of an air vent port at the top of the water chamber. It would be nice not to have to pipe a tee in the boiler discharge when space is an issue.

more info

each kick space...with a wall mount kit aech rated for 3 gpm at 160 degrees will give me approx... 7800 btus ...install two would be increasing the flow to 6 gallons per min. which would in turn give me a load of 360 gallons per hr. i was looking or hoping to use a small 40 50 gallon electric water heater...

thanks for replies

Concept makes a good electric with a vented tank

I never saw a kickspace heater rated at 60,000. Normally they are about 5000, 7000, or 10,000; and you will not see 20 degrees temperature drop unless your flow rates are really, really, slow.
