New steel panel radiator install

[Deleted User]

We have used the Biasi ones. They are competitively priced and install like the others. The adapters that come with them are Oventrop. They also have a line of towel warmers too.

New steel panel radiator install

I'am replacing a 80% efficient, single zone gas furnace in a two story house. I would like to install steel panel radiators with home run/manifold piping, TRV's, and constant circulation. Any recomendations on panel(Veha/Buderus?), 5/8" pex-al-pex, and TRV manufacturers would be greatly appreciated.

I like it!

Buderus, Dianorm and Veha are all just about the same, and Danfoss make the TRV's for them. The TRV's may have different names on them, but they are all the same.In most cases, 1/2" pex will be acceptable, and my personal prefferenc is Viega Fosta-pex.

Go for it! You'll be very happy when the "furnasty" is gone, and far more comfortable too. Chris

Biasi too...

Don't forget Biasi has a line of steel panels too, the pricing I got from my distributor was less than Veha or Dianorm. They all look the same, I'm not so sure there isn't a factory somewhere cranking them all out and labeling them for each brand!

Sounds like a plan

even down to the tubing type and size. Hard to go wrong and we know you got your basics down.

We do lot's of them

Our system's typically are piped via a common manifold serving all the rads. One other option that we offer depending on the home and its layout is to use multiple manifolds for each area of the home. These will each have their own circ controlled by a master thermostat with each rad still having a TRV. We are currently done with the rough in for a house with 15 rads/towel warmers. All the rads are on a single manifold controlled by a mater thermostat for the whole house. This will enable the HO to utilize setback of temps when the whole family is gone. (This happens quite regularly for this particular family)

Weapons of choice for this particular job:

TRV's, Oventrop

Tubing (FostaPex) and manifold (stainless), Viega

Boiler, Prestige 110

indirect , Triangle tube

Panel Rads, Radson series 22

Rad fittings, Oventrop Multiflex

Look up www.hydronicalternatives.com for a wealth of info on systems of this type.

Steve, thanks for the reply. With the house being two stories, would it make sense to have two master themostats and manifolds? This would alow set backs for the the two living levels.

Thanks,

Phil

if dong constant...

circulation w/ TRV's seperate zoning and set back zoning is really not needed. kpc

As always.......It depends

It depends on how the second story is going to be used. Is it just extra space to be used once in a great while? Is your mother in law going to live there some day? You are the person who knows what the intended use is both now and in the future. Personally, I like having the option of different setback schedules for different areas of a house.

A house full of steel panel rads is sweet!!

I am installing SPR's with a towel rack today in a home that was all electric baseboard. I always use Buderus steel panel rads but that is what available to me locally. In this homes case it will be on constant circ with each panel having a diverter valve underneath and of course a Danfoss TRV. I built a simple homerun manifold for distribution. I will post some pics later. The degree of comfort these folks will have inconjunction with the energy efficiency of the system is win-win!!

I only wish that I had the Wilo Eco pump available right now!!

Panel Rads

My personal preference is Veha panel rads with Oventrop TRV's. Typically panel rads that are more of a square shape are a better value ($/btu) than those that are tall and skinny or short and wide. The 12" tall radiators they offer are nice for low windows. The Oventrop XH thermostats are relatively large. The DH thermostats are smaller.

Where do you locate the master t-stat?

Steve,

Where would you mount the master T-stat? One would think the room that would demand the most heat?

Vehas

Here are 3 Vehas I installed on the east wall of my studio. 3 more on the west side. The first 3 are on a manifold but that was too much plmbing so these are much simpler. 6 rads, I think 15" by 53" or so, double wall heat the 44x38 foot studio with 14 foot ceiling. The wood floor is over concrete which is the ceiling of the basement apartment with radiant floor. Run around 165* The TSR's are in a box.

Here are 3 of 6 in my studio. They are the double wall variety. 15" x 53". TSR's are in a box.

Sizing and suplemental radiant

If you are using a condensing boiler, I suggest you size the rads for 140-150 deg supply at design temp. This may have an undesirable aesthetic impact, you might consider supplemental floor heat to permit smaller less imposing rads. This floor heat since only supplemental and operating at the same temps as radiators would not require expensive conductor plates. The trv's would balence the more responsive output of the rads with the floor and in effect provide the indoor/outdoor feedback of a high end radiant system without expensive electronics using the elegance of analog trv flow control.

Typically........

That's true. You would want the room with the stat to be the last one satisfied. I have however located them according to the owners preference. One of them was right next to his bed. He didn't want the heat down until he was covered up. Sometimes you do what makes sense and sometimes you do something else. Ya know what I mean???
