" In the energy wise home, we're using a radiant floor heating system, and to provide the hot water for that radiant floor heating system is a high efficiency boiler. In fact, it's so efficient that only 5 cents out of every dollar goes to the flue system. With me today is Matt Connolly from Monitor Products. Tell me about this boiler."

" Well, it's a fully condensing stainless steel boiler. Fully condensing means that if you see the water droplets here, whenever you burn fossil fuel, one of the by products that arose aside from heat is water vapor. Most of that water vapor and a conventional boiler has to be maintained as vapor and sent out the flue. There's tremendous loss of heat there. With a condensing boiler like this one, you actually structure it in such a way so you condense that vapor on to this heat exchanger tubes. You transfer that vapor to heat, pouring water droplets which fall off. That's how you can get 95% to 97% efficiency out of the unit."

" Which is so efficient it takes so much energy out of a fuel that, you know, that it actually pass as convincing."

" For example, the outgoing water temperature to the radiant floor system is usually 30 degrees warmer than the outgoing flue. That's why the flue is plastic."

" Amazing. Other attributes about this boiler."

" Well, this is a sealed combustion boiler also. It takes its intake air from the outside. It brings it through the cabinet. It then enters into the combustion air blower. This is the combustion chamber. The condensation occurred at the bottom. The exhaust vent is here. This goes straight out and back out. So there's no room air use. You're not burning that air you pay to heat. The unit comes with a system, circulator pumps, an expansion tank, a condense trap, a return water strainer, the bypass valve in here. There's a flow switch in here, low water cut off. There's a release valve. All that is built in and integrated into the system. All of these things that in a normal boiler you have to plump and wire and control separately, but in this system, it's completely integrated so when it's hung on the wall, which also saves space, there is so work that's already done it becomes a very inexpensive product to install."

" type of heating system than a radiant. What you have here when it's properly controlled, it will be a seamless transition between the hot sunny days and the cooler nights because the unit will anticipate the heat it needs and it will be seamless, so the floor will be 85 degrees when it's 60 degrees outside, and then come morning, it will be back down to 70 degrees."

" Matt, now this boiler you mentioned had a stainless steel heater here. Pretty important?"

" Very important. There's only a few metals that can handle the common state of a condensing boiler, stainless steel being the most important metal to do that. In a normal boiler,----"

" But it's corrosive."

" Well, the common state is slightly corrosive, and over time, that does add up. A cast-on boiler can't do it. An aluminum boiler can do it with a lot of servicing. A copper tin boiler can't do it. So our standard steel can't do it, but stainless steel is the only material, and this is 316 L stainless steel, which is perfectly suited for a condensing product."

" Let's walk through the entire heating system for this film."

" Okay. Well, you mentioned you had radiant floor heat. You're using [unk] tubing, which is an excellent brand of tubing. You need to heat that at a certain temperature and very low temperature. A conventional boiler can't do that without mixing it down, which is very wasteful. With a condensing boiler, you do not have to worry about how cold the water is coming back in it. As a matter of fact, the colder the water coming back into it, the more efficient the unit is. So the unit will heat the water to the designed temperature where the boiler is set. And basically, you'll have a very slow, but steady amount of heat being pushed into the house at all times. By doing this, there's very little waste, and there's plenty amount of comfort."

" Matt, what about reliability. It seems like this is pretty high tech."

" Well, it is high tech, but it's also not new. This technology has been around in Europe for about 20 years. These boilers are very proven. They're very durable. You can see by the stainless steel tube, which there are 14 in the unit. They're gonna last forever. They are considered new in the United States, but that's because our fuel is relatively inexpensive, and Europe, their fuel is far more expensive than ours; therefore, they can't afford to waste anything, and they've developed these technologies years and years ago to harness every BTU possible."

" And what about availability? If I'm interested in buying one of these, where do I go?"

" Well, we have a website, mdboiler.com, and we have a toll free number. We have dealers all over United States and Canada. They're very available. There's hundreds of thousands of then in United States already, and they're very easy to get."

" Well, Matt, you're very knowledge. Thanks for being here."

" Thank you."
