I used the easy mat in my basement with the radiant wire on top of it. It worked great. It has a rated r-value of about .5. I would go with that. Seems to be some kind on foam. So, Cement Floor, EasyMat (buy in large rolls), heating wire, Tile.

Short answer is "yes, but" If you only use 1" xps you will have a vapor/moisture barrier but not have enough r-value (mainly to prevent condensation when the heated air hits cold wall). So, what you can do is use unfaced fiblerglass in the 2x4 stud space in addition to the 1" xps. This should...

The buffer tank is hot at all times. But as far as tanks, it is very, very small. It is also super-insulated, so it is not being heated all the time. It is just enough water to provide the initial burst of hot water

Why are your water heaters failing? If the water is corroding them or are they clogging because of hard water? If so I think you will have the same problems on the tankless as well. You may want to look into a water softener or PH neutralizer.

My understanding is that the condensate is about a acidic as orange juice or soda. It is not immediately caustic. The only thing I am not sure about is the ABS issue, because we use PVC here. But, if you have installed a neutralizer, you can safely drain it to any household drain. By your...

I have experience with Navien. They can be used with external recirc pump or, as Terry mentioned, they also make units with built in recirc. pumps. Even the units with the recirc pumps can be used with external pumps (you just have to set it up to disable the internal pump). Navien is that they...

Just wanted to update this with solution. I found a RANCO ETC-111000 which is like a digital version of an aquastat and includes a sensor. It is like a temparature controlled on/off switch.

Thanks for looking at my profile. I am an entrepeneur and own a laundromat in Syracuse NY and a appliance repair business. As far as home improvement, I did a total build out of my basement making sure to get everything inspected and permitted. This forum was a big help on that job.

Hello, I need to install a controller or aquastat that will turn on/off my recirculation pump which is connected to my tankless water heater with external storage tank. I am looking for reocommendations. I am converting from an old boiler water to a high efficiency tankless unit (for...

Hi All, It has been a while. I have a commercial boiler with a 120 gallon hot water storage tank on a recirculation pump. The boiler is 20 years old and I want to retrofit a high efficiency (Navien) tankless water heater. My concern is with the water supply pipe sizes, which need to be...

I just want to increase the CFU/Minute

The check valves are a great ideal. This set up would be parallel, right, with the two tanks into one?

Hi, I have read that it is possible and safe to combine the output of two air compressors for high CFU applications. I was wondering how to accomplish this. It seems to me that using an unregulated air tank would be the best way. So the input of both compressors would be connected to the air...

Hello again, I have a 1 1/2" riser roughed in in my basement for a bathroom sink. I want to connect two sinks to it: one for the bathroom, and one for a wet bar sink adjacent the bathroom (about 3 feet away). My question is, can I use two sanitary tees (one above the other) or do I need a...

I did about 12 square feet of 4" slab with the following method: Rotary Drill with masonary bit drilled a circle pattern about 4 inch in diameter (big enough to get your hand in) Heaviest sledge hammer I could get to open up the circle. Once you can get your hand in there, remove as...
