Most water heaters are only in service for 2-3 hours per day and they often have enough capacity to do extra work. If the BTU heating output of the water heater is equal to or greater than the heating load, you can probably use it to heat as well. Look at the label on the heater for the BTU output.

We have had good luck with the Polaris, but it does require competent installation. You should have a competent gas man do the work. This is not a good do it yourself project. Some people should have been given their money back instead of getting a new Polaris, because the problem is at the site.

A sulfurous or rotten egg-like odor in the hot water is caused by bacteria growing in the water heater. This usually happens when the water heater is turned off while on vacation, when the hot water has not been used for a long time, or when the temperature setting on the heater is set too low. The bacteria in the water heater are not a health threat; however, they must be eliminated to stop the odor problem. The procedure for eliminating the bacteria is called heat disinfection.

All solar water heating systems deliver both higher temperature water and more water volume than conventional water heaters. They heat typically 40 to 80 gallons more water than conventional water heaters.

We have provided a heater specially designed for iPool. It includes a heater, a filter pump (1000gal/hr), and connector. The heater is optional for iPool, the cost is $600 plus $60 shipping and handling fee. Please click iPool Heater for more information.

Only in areas subject to temperatures below 40 degrees for three or more days in a row. Water in the bio tanks should be kept at above 60º degrees F., 70º F. and above is ideal.

Yes. Since the water heater will operate far less frequently, solar will extend its life significantly.

It should be .There will be low heat output and high energy cost. They may be acceptable in intermittently occupied buildings or as a back up only. There will be a prompt payback of the added cost of any other form of energy.

The heated water is pumped to the home or building through insulated underground pipes. Water-to-air or water-to-water heat exchanger or direct circulation conveys the heat into the structure's forced-air furnace, boiler, or radiant floor heating system, and to the water heater to provide domestic hot water. This allows for normal thermostatic control of temperatures for safe, even, comfortable heat.

Using what is called a desuperheater, GSHPs turn waste heat to the task of heating hot water. During the summer, when the system is in cooling mode, your hot water is produced free as a byproduct of the thermal process. In winter, with the heating mode, the desuperheater heats a portion of your hot water. Desuperheaters are standard on some units, optional on others. Stand-alone systems that will heat water all year around can be purchased.

Not if your hot water tank is heated with natural gas. We sell solar electric systems that provide electricity to your home.

It is impractical to use solar-generated electricity to heat water. A solar water heating system is a far more cost-effective choice. Similarly, space heating is best accomplished with solar thermal strategies or equipment designed for the task: passive solar designs and radiant heating, for example.

Discharge of heat from the ETS equipment is automatically controlled with fans/blowers. These fans/blowers operate as needed to satisfy the heating requirements of the area as sensed by a room temperature thermostat. When there is a need for heat, the room thermostat signals the fans/blowers to operate and discharge heat. When the heating requirement has been satisfied, the fans/blowers turn off. Return to index

Testing by Florida Utility Companies and the State Energy Center reveal that heat recovery only saves about $39 to $69 a year - only 1/10 of the savings of solar energy systems. First, a heat recovery unit does not save any money when you are not heating or cooling. It saves the most money when you are air conditioning, because during this time the heat pump or air conditioner has free heat to expel.

Yes, but check with your local code enforcement department (some require boilers only) and make sure your water heater is sized correctly for the area you are heating. Set the water heater temperature control to high and make sure to install a thermostatic mixing valve and expansion tank.

There are many variables that dramatically affect heat loss, but here are some general guidelines, based on a new construction radiant slab, well insulated (walls, ceiling and under slab), in a moderately cold winter climate area using a thermostatic mixing valve: A standard 50 gallon electric water heater with (2) 4500 watts elements and a 20 gallon per hour (gph) recovery rate can usually heat about 250 sq ft.

When you open a faucet, the flow of the water triggers the heater to turn on. Whether you use gas or electricity, the powerful gas burners or electrical elements will turn on, rapidly heating the water as it passes through the unit. The water is heated instantly, and the time it takes to obtain hot water is directly related to the distance the hot water has to travel from the water heater to where hot water is being used. The burners or elements then shut down when you shut off the hot water.

In many cases an existing domestic water heater will do the job. If the BTU rating of the heater is matched with the BTU requirements of the space to be heated, one properly sized unit can provide both space heating and domestic hot water. A boiler is normally not necessary unless the heating requirements exceed 300,000 BTU's. In these cases, a simple mixing valve is designed into the boiler system to provide lower temperature water to the radiant floor.

The AirTapTM plugs in directly to any existing gas or electric water heater. The device mounts above an existing tank using mounting brackets, which are provided with the unit. Simply connect the AirTapTM to the water tank and switch off the electric or gas supply. A user's manual, provided with each AirTapTM unit, goes through a step-by-step procedure, which should be followed for proper and safe installation.

We prefer not to install this kind of system. We feel it is an inferior product and potentially dangerous. We highly recommend using appliances without open flames (see #26 below) For the ultimate in heating and cooling, you must have separate systems.

Yes. You must choose the proper model to suit your home's hot water needs, which is based upon the maximum flow of hot water you need at any one time. We sell tankless water heaters that are capable of handling one shower at a time and others that can sustain a maximum of two showers operating at the same time.

Braided water heater connectors may be looped, however, not less than 3" in diameter. Copper water heater connectors may kink and flatten in tight bends and should be not looped to fit in the installation.

Yes. Using what's called a desuperheater, some types of geothermal heat pumps can save you up to 75 percent on your water-heating bill by pre-heating tank water. Desuperheaters are standard on some units, optional on others. Some geothermal models can provide all of your hot water needs on demand at the same high efficiencies as the heating/cooling cycles.

A shell and tube water-to-water heat exchanger is mounted on your existing water heater. A water-to-air heat exchanger is installed in your existing duct work. Heated water from the furnace travels through the water-to-water heat exchanger heating the domestic hot water in your tank. Next, the heated furnace water is piped through the water-to-air heat exchanger to heat the air that is blown through your existing duct work.

You can take endless hot showers with the hot water the Titan provides. Because it does not use a tank, there is no limit, no hot water to run out of. You and your family can enjoy shower after shower without running out of hot water. And since the Titan heats water only as it is drawn, you will also save on your water heating costs. You will save AND have an endless supply of hot hater on demand.

Yes, but evidence indicates that smaller water systems such as those used in homes are not as likely to be infected with LDB as larger systems in workplaces and public buildings.

Note...While Kero-sun and Toyostove brand portable heaters are no longer sold in the United States, the following information relates to those units that were sold on prior years.

A third cause is that the hose splice is on the wrong side of the water pump. This problem dissipates once the thermostat has opened. Due to how the cooling system is configured on some engines, this problem can be easily remedied or not - refer to the standard heater hook-up diagram in our documentation section.

The way data bits are encoded into bits on the disk (the modulation system) was changed from EFM ("Eight to Fourteen Modulation", the Compact Disc's method) to the more efficient RLL1,7 (typical of hard drives).
