Yep, all 4 walls are insulated.

But the space above where the heat would rise to would be hotter than the lower space, so doesn't that mean that I wouldn't really lose much heat in the basement storage area? Plus, there is 2" foam board between the slab and precast, so some heat might go into the precast but then the foamboard...

I'm currently building a house. I have a 14x30 basement storage area that is under the back part of my garage. The garage slab will have hydronic heat, 2" foam board under the slab, vapor barrier under the foam, then precast concrete. The storage area ceiling is the bottom of the precast...

Thanks for the great info! I might take you up on the PM when I get around to installing the system.

Oops! Here is the correct link Each of the three zones will have their own manifolds, the basement manifold will be in the mech room right by the boiler, the garage will have its own manifold in the garage. I'll run pipe from the boiler/radiant system to that manifold (about 10 feet) and the...

I decided to bite the bullet. I'm just going to have the builder's HVAC guy bury the pipe in the slabs. Thanks for all the feedback!

I'm going to put 3 zones of hydronic radiant heat in my new home. The basement (1906 sq ft) will be one zone, this will be kept at 70-ish degrees all winter. The garage (1780 sq ft) will be another zone. This will likely be kept around 50-55 degrees but will be turned up for days that I plan to...

It will be a smart home (using Home Assistant) so I have explored that and it appears there may be a way to do it. But, others have brought up good points about actually wanting individual control. Another question, do I need to use the included copper lines that come with the unit? I'd prefer...

The land has been deeded to us (or will be shortly) and we are carrying the construction loan and builders risk. But, he owned the land and we had to sign a purchase agreement before he would deed the land to us and build the house. In that purchase agreement it basically states that we are not...

Do you mean I can sync the remote so changing the temp on one remote will change the temp for all zones? Or would I need to change the temp on the individual remotes for each zone?

I'm building a house with a 1780 sq ft garage. Based on my calculations, I would need a 40K BTU A/C unit. Because of the layout of my garage (L-shaped) I'd like to have multiple air handler units but all on one zone. I can find units with multiple air handlers but all with their own zones. Does...

The builder owned the lot that we wanted, so we are stuck with him. He builds a nice house, but is difficult to work with. He prefers to use his subs to keep things on track and probably transfer the liability if something goes wrong. To him I'm just some guy that thinks he knows what he is...

My dad has radiant heat in his pole shed, I've used it and like it a lot. My home builder won't let me put the PEX in myself, even though I've done it a dozen times (I worked in HVAC in college and did my dad's shop). The quote from his HVAC guy was $8,800 for the basement (1906 sq ft) and the...

The cost of the foam is already in our bid, I'm estimating it's about $3,000 (about $1.70/sq ft). The additional cost to add the pex in the concrete is $4,000 (about $2.25/ft). We are already over-budget, so I'm not sure I can convince the wife to spring for the extra $4k. Have you noticed...

I'm building a new home in central Iowa. The house will have a 1780 sq ft garage attached. I'm not going to put radiant heat in the floor, but I will insulate the garage with fiberglass batts in the 2x6 walls (about R19) and blown in cellulose (R40) in the attic. I plan to use an overhead...

Sorry for the slow reply, I must not have had my subscription alert on. Yep, I plan to use a tankless water heater. I'll get one with enough BTUs Both. Zone 1 will have a standard HVAC system, the floor heat will just supplement that. Do you recommend having a separate manifold in zone 2...

I'm getting ready to build a house and plan to put radiant heat in the floors. On my basement level I will have two zones, the main zone inside the home (zone 1) and a 2nd zone which is a "shop/storage" area built under part of my garage using pre-cast (zone 2). I want to use a single...

I'm planning a new house build, I plan to have an L-shaped garage with one section 24x22 and the other section 26x40. I'll have a tuck-under garage (garage under a garage) under the 26x40 section. I'd like to at least put pex in the floor so I have the option of heating the upper garage in the...

I'm looking at using PEX-AL-PEX for my new home shop. According to the specs it is good up to 200 PSI at 74 degrees, but that drops to 125 PSI at 180 degrees. Not that I ever anticipate the pipe getting that hot, but I know the compressor can get warm and can transfer some of that heat. I...

Thanks!
