If you are searching for a new water heater, be aware that your options now go far beyond replacing your existing water heater for the storage tank with only one like it. As heating water usually consumes around 10 to 15 per cent of the total monthly energy budget of a household, all the best new water heaters concentrate efficiently on heating water.
Conventional Storage Water Heaters The big, common white tall, cylindrical tanks are water heaters that store. You can choose from natural gas, electricity, propane heaters and they hold 20 to 120 gallons of water, depending on the tank capacity. When you are looking for a traditional water heater, the first choice is to buy either an electric heater or a gas hot water heater. In addition to considering the price, take a look at the yellow Energy Guide label to help you make your decision.Check waterheaterreviewssite.com
Make sure to test the amount of the first-hour rating (FHR), as this shows how much hot water the heater will supply at peak consumption per hour. Look for the energy factor (EF), too, as this indicates how well the device can convert its fuel to heat. The higher the EF number, the more effectively their energy is used by the water heater. Electric heaters for hot water tend to have higher EF than those for gas systems. But while electrical units can use their power more effectively, in most regions electricity is a far more costly power for water heating than coal.
Alternatively a higher efficiency boiler can be combined with an indirect water heater. You may need a separate storage tank to mount an indirect water heater. This combination will give you the cheapest way to heat water and help you save money in the winter months particularly. For adding hot water to homes, shops or garages, portable water heaters are good choices. Such heaters are energy-efficient, and can supply unlimited hot water on demand without water storage space and cost.
Whole House Tankless Water Heaters Also known as Instant hot water heaters, do not store water. They heat water instead, as it moves through a series of coils in the device. While a tankless water heater can provide an infinite amount of hot water, it can only provide a limited quantity. Many tankless systems can provide heated water up to 3.5 gallons per minute. Such devices are a good option for any household whose hot water demand is no greater than two points at a time. These are also suitable for families with small households and little room for large water heaters.
Propane, natural gas, and electric tankless water heaters are eligible for your choice. Consumers interested in tankless gas heating need to test that home gas lines meet the demands of a whole household tankless gas water heater system and that ventilation is sufficient for this form of water heating. Although tankless gas water heater requires good ventilation, some units have power vents which allow you to exhaust gas from a side wall; these are ideal for situations where it would be impractical to run a new vent out of the roof. Rinnai, Bosch, and other companies produce devices that can be mounted outside the home and thus do not require ventilation, but in extremely cold climates these may not be practical.
