- This video discusses the features and benefits of the Open Direct System which uses one high efficiency water heater to provide hot water for radiant heating and domestic use. This video also discusses the benefits of using the highly efficient Polaris Water Heater as the heating source instead of a boiler.
How does an open system avoid freezing as opposed to a closed system with antifreeze?
Dumb question - would you expose the pipes coming from the water heater or hide them in a wall? My water heater is in a laundry room currently, and as an old house the plumbing is exposed. So this would fit right in to the Rube Goldberg look.
Is there Polaris water heater available for LP gas?
Nice idea but stagnation is a problem
How do you control the temperature in each zone? Maybe I don't want to heat the 3 upstairs bedroom, but want the bath to maintain heat. I don't see thermostats being used on these schematics. Am I missing something?
As far as I understand it, each heating zone has its own thermostat to keep each zone at the desired heat
When heat is called for and the pump turns on, how is that not also drawing in cold water from the supply?
Is open direct able to be done by a tankless water heater?
It seems like when domestic water is called for, the replacement cold water will be circulating through the in floor system before reaching the tank. isn't this counter intuitive, in such i mean the supply cold water will be cooling the infloor system? looks like some efficiency would be lost.
Hi, this is a great question. We send the cold water through the supply side of the system as an important safety feature. We need to make sure the water remains fresh year around, even in the summer when you're not using the heating system. We don't want to rely on someone having to remember to switch valves or a mechanical device that could fail.
Keep in mind that when a radiant system comes on, it will circulate warm water for many hours to heat the floor and all of the object within the room. Once the room does get up to temperature, it takes only little inputs of energy to maintain that temperature. Since it takes so long to warm up, it will also take a long time to cool down. You can take a couple of showers and do some laundry and running that cold water through the floor will have zero impact on cooling the room. In fact, what heat the water does pick up gets put back into your water heater so there is no net heat loss on the system by doing this.
Do they have electric boilers as well now too?
Electric is not as efficient as gas and subject to multible malfunctions...
When I built my house in 2009 I tried for 3 months to buy this Polaris water heater at whatever price they were asking (...over $3,000).
The local plumbing supply company said that it was readily available.
However, after three months of following up they were unable to deliver.
I eventually canceled and purchased something else.
I think you should find a better unit to associate with your products with, because the Polaris unit is a disappointment in price and availability.
HI Dana, we deal with a distributor that has warehouses all over the country. We've had people receive a water heater at their door in as little as 2 days! On a rare occasion when we have to ship one directly from the manufacturer in TN, it could take up to 2 weeks.
The Polaris is a great water heater in terms of it's strength and efficiency. We've used them for about 20 years in applications shown in the video with great success. Keep in mind these heaters are 95% efficient, stainless steel, and are vented with plastic.
My home is near Boston.
Is there is a distributor / warehouse near me?
Would you share whatever info you have.
Thanks.
Dana, the company we work with has a warehouse in Worcester, MA. If they have the particular heater in stock you could get it in a few days. Give us a call and speak with one of our techs if you have any questions. 800-451-7593
Yes, we carry a line of boilers that can heat a house of any size. www.radiantec.com/product-category/electric-boilers/
We have quite a few heaters. One uses electricity while the others use LP or NG.
Without doing a heat loss calculation, it's difficult to say exactly what you would need for a heater. But, in a newly constructed home, 1 Polaris water heater should be able to handle the heating load, we just don't know which model you would need. The best thing to do is let us work up a free quote for you: www.radiantec.com/pricing/full-quote-form/
Also, the Polaris comes in Propane or Natural Gas, not butane.
Mmmmm, Legionnaire's Disease. Thanks Radiantec!
That water heater is over $6k and is currently unavailable...not really a viable option for most people but must be nice if you are loaded
polaris thing cost lot more than high-efficiency boiler.
Looks like a hostage video or something from the 50's!
Buyer beware if you don’t buy there system they will not work with you at all there. There answer every time you have an issue is well that’s how it supposed to work we can’t explain it and won’t fix the issue
Example?
Co2 is not pollution.
