Polaris Combines Space Heating with Water Heating

The Warmth of High-Efficiency Space and Water Heating

Polaris® works great for homeowners who prefer radiant hydronic heat based on a heat source that is simple, efficient and familiar to homeowners and plumbers alike. With radiant floor hydronic systems,  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 thousands of Polaris's over the last several years.  They have proven to be extremely efficient, simple and dependable. The Polaris is on par with the most efficient radiant floor hydronic systems on the market and its stainless steel construction offers a long life compared to typical water heaters. 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.  Standard 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 boilers and will drop the efficiency rating.

Polaris water heaters are immune to these problems and can deliver their rated efficiency at any flow. Polaris water heaters can heat both your home and all provide all the domestic water you can use - whether in an open or indirect system.

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.

Non-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.
