Tankless Water Heaters

The tankless water heater offers home builders a number of benefits also. You have the ability to upgrade to a more costly, space saving, and energy-efficient appliance. Today, they are set up in many zero energy houses. Also today, most custom-made houses are being constructed with a whirlpool system, high output showers, showers or tubs in other rooms, large capacity washers, and dishwashers. All these put a substantial strain on a standard water heater. Then there is a recovery period when even the biggest units run out of hot water.

A tankless water heater is a fairly basic principle. Instead of a constant draw on resources to heat, maintain, and reheat water in a big tank, the tankless water heaters will flash-heat the water as it is required by running through a heat exchange. When hot water is required, sensors will signal the burners to light, and then heat up the water. When the hot water is no longer required, the whole system simply shuts down and there is no pilot burner. This, and the fact that there is no recovery period, can save 40 to 60 percent on your utility bill.

A tankless water heater system is also compact and can be mounted to either an exterior or indoor wall to conserve floor space. Because they are combustion sealed, they can also be set up in the closet.

Tankless water heaters in the past few years have had a 20 to 30 percent sales boost each year. But, they still only account for about 2 percent of the overall residential water heater market.

Part of this is the fact that some home builders are jumping in the tankless water heater parade, yet others are holding back while taking a more cautious approach. Also, part of the increase is due to the fact that clients are more well-informed and familiar with the tankless water heater benefits.

The flow rate or capacity that a tankless water heater can provide is dependent on the heating element. The bigger the heating element is, the bigger the capacity or flow rate will be. It is also affected by the difference between the water temperature and the temperature it needs to be heated up to. This is also referred to as rise.

If a tankless water heater needs to heat up water to an extremely hot temperature, such as the case in the colder regions, it will have a lower flow rate. A basic shower temperature is 105 degrees. If the water needs to be heated up from 65 degrees (which is common) to 105, it will do so a lot more effectively and with a greater flow than heating the water from 35 to 105 degrees.

The biggest hurdle to clear with a tankless water heater is the initial cost. This cost is 2 to 3 times greater than a standard system. A couple of long term factors should be looked at. First is the energy savings, as lots of states now offer energy rebates which can also decrease the overall price. You also need to look at life span and repairs.

A traditional system is not made to be fixed, as they are made to be replaced. A tankless water heater usually has a 10 year guarantee on the heat exchange unit, and 3-5 years on the other parts. They are made to be repaired if required.Profile\nNorthern Colorado Air
