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.

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.

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.

Truthfully, that can only be best done if the entire floor plan of the home, insulation value and needs are all considered. It is always best to speak with a dealer, tell them about your home, life style and describe what your goals are for heating with wood.

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.

The heater model and capacity are not necessarily a function of the square footage of the area needing to be heated. The model generally is chosen after the Btu/hr heat loss for the building or spot area to be heated has been determined, which is a function of not only the size of the area, but geographic location, building materials, building usage and other factors. Area coverage could be as little as 500 sq. ft. or as much as 10,000 sq. ft.

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.

One device is adequate for the treatment of max. 150 cubic meters room.(about 450 sqft). However, it is recommended to use it close to you in the room

Generally speaking, for an adequate air exchange rate, you can expect up to 500 sq. ft. coverage for the SE400E, and around 700 sq. ft. for the SE800E. - based on moderate concentration levels w/ 8 ft. ceilings. Individual results will vary based on environmental variables. To find out how many of which air cleaner you need, try our air cleaner calculator in the Buyer's Guide.

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.

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.

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.

Very easy. 100 square meters is 1076 square feet. Surfaces are given in square meters, written m2 or m2.

a. Yes it is quick and easy, trace with the stylus pen around the area and the program calculates the square feet of any area, also trace along any straight or curved length and the program calculates the exact linear feet.

The Allergy Machine™, HealthMate™ and HealthMate+™ have 60 Sq. Ft. The HealthMate Jr™ Model has 30 Sq. Ft.

There are 43,560 square feet in one acre. Therefore, if the size of a property is 0.20 acre, then it would measure 8,712 square feet (43,560 x 0.20 = 8,712).

We go by unit price and not by square feet due to the fact that square footage is not accurate and often works out to be more expensive. If you have a lot of windows, we can offer a volume discount. Unit price varies depending on how many windows you do and what is involved.

The Ski Suites (1 - 2 people) are approximately 350 square feet. The One Bedroom condos (2 - 4 people) are approximately 525 square feet. The Two Bedroom condos (4 - 6 people) are approximately 825 - 1000 square feet.

The square footage given for each plan is based on heated floor space. This does not include decks, porches or garages. Due to varying methods of calculating the total square footage, it is recommended that final area calculations be done by you and your builder. The room dimensions given on the floor plans are rounded to the nearest inch. As you will see, it is not always possible to give specific room dimensions due to the open nature of some floor plans.

Depending upon the type of material and the accuracy of the rough grade provided the Laser Grader can grade up to 50,000 S.F. per day. Northeast Laser Grading offers high precision grading for supermarkets, warehouses, parking lots, athletic fields (football, baseball, soccer), tennis courts, horse arenas and more.

One of our sales representatives will come out to your house and measure. From the measurement they can let you know how much square footage is needed. If you want to know the exact formula, just ask... they will be happy to teach you. You may also draw a rough sketch with measurements and fax it to us. Just be sure to include your contact information.

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.

You are not "immune" to an STD if you have had it before. STDs caused by bacteria (chlamydia, gonorrhea, and syphilis) can be treated and cured, but you can get them again if exposed. Viral STDs cannot be cured and may remain in your body forever.
