Who owns an Empire DV-215 heater?

Is it practical to run one of these off a pair of 20# tanks? Not so much from a run time aspect, but as far as providing the correct pressures or vapor volume needed for that size of heater. Last year I tried with an auto changeover dual regulator, and I struggled to get things going right. People are saying I should ditch the auto changeover dual regulator and go to a 2 stage single regulator and combine both tanks together as one before I feed the regulator with a single line? A better way to have more vapor volume available, especially in the coldest weather? What brand of regulator is considered the better quality, especially for real cold usage?

I wonder if that’s why alot of fish house builders are fitting 30 lb cylinders. Maybe they provide more reliable vapor pressure / volume?

I just talked to the guy who fills my propane bottles and, yes 30 pounders perform better than 20s in colder temps.

So does anyone know if I bring two 20# tanks together into a single line feed before it goes into the single input regulator, do the pressures from each tank add up to a higher pressure into that regulator? Or doesn’t it work that way. I’ve heard that a tank’s pressure is around 100-150 psi each. Can I use a brass Tee fitting I’d find at Menards or H.Depot and it be OK with the pressures we’re talking about?

I would ask an RV dealer as they fix and repair lp gas systems.

The pressure won’t be any higher ,it’s just that each can,can only boil off so much liquid at a given temprature [turn liquid into a use able gas] so the combinded pressure is enough to keep up too the BTU output and keep our appliance running.

I’m trying to source out a Tee that will feed my 2 tanks into the single inlet on my regulator. I’m seeing a choice between a manifold Tee like this:

or one similar but also mentions it is a Tee Check:

I guess the one with the check feature would let me leave one tank running while I switch out the other? In the end I want to generally have both tanks running at same time to maximize vapor volume available. Would the one with the Check feature designed into it possibly have more restriction to it? Not a Full Port idea?

The one at Dyers Online looks different, but maybe it has a Check feature also, they just don’t mention it.

The check feature seemed like a good thing, as I wasn’t wanting to add 2 more shutoffs directly off the Tee to isolate the one tank that would be left running temporarily.
