Hi, I’ve read through all of the posts concerning radiant floor heating and still have some questions. We are in the process of planning a renovation of a 2600 sq ft. 3 story attached brownstone. The house is in “estate” condition with original details we wish to save, but all of the systems of the house are shot.

We are replacing all plumbing, electrical and heating. We are also doing joist sistering on the 2nd floor and 1st floor extension. A lot of the demolition has been done so we can see hopefully all of the issues we are facing. We will save the plaster ceilings on all floors, original parquet on 1st floor. The flooring on 2nd and 3rd floor as well as as 1st floor extension has been removed in order to perform electrical, plumbing and joist repair.

The architect proposed mini splits with hyper heat. I’m fine with this for supplemental heat and of course cooling. I really don’t want to be cold or too dry in the winter and think since we are taking up the floors on the 2nd and 3rd floors, that putting in a hydronic radiant floor heating system makes sense.

My spouse is concerned that is the system has problems or leaks that we’d have to rip up the floor. I’ve not seen evidence of this in my research, but maybe someone can educate me about the pitfalls.

The architect thinks a radiant system will be very expensive and blow our budget. I got one rough estimate from a plumber of $50K, which doesn’t phase me considering some of the other costs. Any knowledge of the typical cost in NYC?

This particular plumber did tell me that an electric hot water heater with heat pump is not code for NYC. I have friends in Philly installing this. Can anyone speak to what is code here? I’d like to consider eventually adding solar to mitigate the ongoing costs. Or should we just go with gas since the current monthly cost would be lower than electric and/or is an electric hot water heater not up to code for this here?

Lastly, I’d like to also use hydronic radiant heat on the 1st floor under the existing parquet. We have access to the joists underneath in the basement. We would install reflector plates? Plumber thought this would be fine, we just would have cold spots where the existing joists run.

Anything else I should consider?

Thank you!

Is this a passivhaus? Or something with a really tight envelope?

you can’t use a hot water heater for space heating in nyc…you have to use a boiler…for what you are describing, the standard in nyc is a HE boiler split into various zones, either by multiple pumps or zone valves or a combination thereof. I’m not a fan of reflector panels, warm board is (in my opinion) a way better choice, but naturally more expensive. Personally I don’t lie the quality of heat produced by heat pump mini splits, especially on the real cold end. If you are even considering that as a viable option i assume that you are hyper insulating the envelope and replacing all windows

Not a passivhaus. It’s a normal brownstone.

We are replacing the windows at the back. I’m undecided on replacing front original windows. We are landmarked.

Do we need a boiler for heat and a hot water heater for hot water?

Or a combination boiler that does both

its your choice…boiler with separate hot water heater, boiler with indirect tank, combi boiler (probably with a buffer tank) depends on the location of the machine room, etc you will probably need to reline the chimney which is generally around 3 grand…

Re-lining the chimney is at least double or more now

There are many variables with radiant depends on how it’s done and the materials used. Warmboard is expensive but you can skip sub floor. However depends on the area you are installing it. Retrofits can be harder especially if you do it in some areas vs others – you may need to meet an existing floor height etc.

Definitely nice to have, but
A quick Google search says warm board is $1
0-$15 installed, in nyc $ that’s $18 😉
Then add pex, manifolds, condensing boiler, permits, labor, insurance, trash plus „everything is double after covid“ – I would probably keep 20k stashed away just in case.
Also make sure your plumber has done this work before and you don’t pay him to practice on your job.

The combi boiler and manifold zones will be at least double the warmboard. The boiler distributors will have a list of plumbers. I had to inform the plumber on all the venting rules as had been burned before so I was cautious. Augustiner’s numbers are right though NYC there is no 0-14, I’d start at 15 for base cost. Anyway there are other options to Warmboard.

I’ve installed over 200,000 square feet of radiant heating and more than half has been with Warmboard. It’s by far the best way to do it but it’s pretty labor intensive for the carpenter/GC.

Thanks for all the comments and information. Has anyone worked with eco warm radiant board? It looks like it may be easier to install and maybe a better product. Also, anyone have experience with installing from the underside of an existing floor? We have one floor we aren’t removing and I want to understand feasibility or any differences in cost.

At a glance, Eco Warm looks pretty much like the same thing as Warmboard. Same process.
Installing on the underside of a floor is my least favorite method. You have to run the water temperature too hot to achieve any savings.

@MP what do people do for cooling with Warmboard. Mini Splits? Also how popular is trench heating?

Judging from the plans I get from Architects, Engineers, and Contractors lately, I’d say no one heats a home exclusively with either radiant floor heating or mini-splits. It’s always a combination of at least those two systems, and yes, “trench heating” is certainly common in areas where it isn’t desirable to give up floor space or where a wash of warm convective air currents serve to keep condensation off a cold surface like a glass door or something.

Thank you. Very helpful answer. I always thought mine was messy as I have a combination. I expect it’s more common than we think as people don’t necessarily want to redo floors or run ducts.

My in-slab hydronic radiant is all the heat we need on our just over-50% above grade lower level. Low temp. Crappy windows.

hi again, I finally got a VERY informal quote from the plumber via my GC. I get the feeling they don’t want to do this. Was told it would be almost $100K to only do less than 2K sqft of the house. This would be two upper floors and one lower floor of the extension. So over $50/ft. This does not include the warm board. Any opinions here?
