Polaris Water Heater

The Warmth of High-Efficiency Space and Water Heating

Polaris® works great for homeowners who prefer radiant hydronic heat. With radiant floor hydronic systems, potable hot water is circulated through the tubes under the floor. The floor absorbs heat from the tubes and radiates it into the room.

We have sold over 2,500 Polaris's in the last five years, they have proven to be extremely efficient , simple and dependable. The Polaris is the most efficient open radiant floor hydronic system on the market and its stainless steel construction offers the longest life of any open system. Boilers have been used for radiant hydronic heating for many years; they have performed well with cast iron radiators and if combined with a circulator work well with baseboards. However, boilers require large flows of water through them to last and to maintain their efficiency. Radiant heat systems often have flows of less than a gallon per minute. Lower flow rates will shorten the life of any boiler and will drop the efficiency to less than 50%.

Combo-heaters are immune to these problems and can deliver their rated efficiency at any flow. Combo-heaters heat both your home and all the domestic water you can use.

Why Condensing?

A condensing gas-fired water heater can avoid losses associated with conventional units. Typical boilers and non-condensing heat sources tend to short-cycle at less than full load and leave un-recovered latent heat in condensate water produced during the combustion process. A system which incorporates features that minimize cycling and that recover additional heat from condensing moisture in the flue gas stream can achieve dramatic reductions in fuel consumption, operating costs, and emissions.

CondensingNon-condensing-type hydronic boilers and water heaters are unable to recover the latent heat of water in the combustion products of fuels that contain hydrogen and are , therefore, subject to the theoretical limit of the heating value resulting in published full-firing rate efficiencies of 78--85%. In addition, cycling losses of 10--50% may be incurred by units operating at less than full load. Another disadvantage with cast iron boilers is that they must operate at 180 degrees to prevent damage from condensation on the fireside of the vessel, this incurs additional losses in the form of higher exhaust temperatures. Condensing heat sources can be operated at any water temperature the radiant system requires, assuring the highest efficiencies in any operating conditions.

Fred,

I have some firmed up consumption now on our Trinity T150. The days in this period were low to mid-30's, some in the mid to high 20's. Nights ran anywhere from the single digits to the low 20's, mostly in the middle teens. It appears that we have used 120 gallons over the period of 30 days, or about 30 gallons a week at a set temperature of 69.

Plenty comfortable in the house, and the heat is much more even...no hot-cold-hot stuff anymore! This propane consumption is less than half what our Slant Fin boiler was using!!!

My huge shop building customer who is heating not only that building but his house as well (with a T200), has averaged about 75 gallons a week since commissioning November 25. Total sq. ft is around 6500, over 3X the size of my house. He runs the shop at 60 degrees, the house at 66. The buildings are 110' apart. No complaints from anyone! Just thought you'd like to know!
