Nowadays an indirect water heater system is among the most energy-saving and affordable water heater systems available on the market. Actually, while coupled with an especially made highly effective furnace or boiler, this device steals the show. Whether you require a substitution for a damaged water heater or you are simply searching for a trendy, water-heating option, a model of indirect water heater must be at the top of your list.
Do not confuse this design with just any water heater without any tank. Although they look similar, an indirect heater utilizes a tank and the heat from the furnace or boiler to render your home with all the hot water you and your family needs. In the indirect water heating system, water is heated with the help of the furnace or boiler by an exchanger connected with the space unit. Then water is moved through the heater to a tank, just like a conventional water heating system, where the water is stored until it is required.
One of the disadvantages of a storage tank water heating device is heat loss. When water is stored in a tank, around 17% of the water can cool significantly. While this may seem like a lot, the alternative is not much better…tankless designs can cost up to 3 times as much as their traditional tank model counterparts.
Indirect Water Heater – The Efficient Option
With an indirect water heater the boiler acts as the heat source; the indirect heat exchanger circulates the water inside the well-insulated water tank, and unlike tankless coil wherein water is heated directly inside the boiler in a hot water heating system. Hence, this indirect unit effectively acts to eliminate heat losses normally experienced with the traditional tank type heaters.
Equated with other options, an indirect water heater saves electricity and cash in different ways. By utilizing your boiler or furnace to heat water, you can save lots of cash in contrast to a conventional model, particularly on chilling months while your boiler or furnace runs on a regular basis.
If temperature remains low all of the time, then a water heater without a tank may be an excellent choice for you to obtain energy-effective water heating. Actually, if you are living in warmer climate then the addition of a tank to an indirect unit is an excellent option.
Best Indirect Water Heater
When there is a question of smart conclusion regarding cost-effective and energy-efficient standards for heating water, few alternatives are extremely better than an indirect water heating system. Actually, solar water heater systems are the only alternative, which bears higher efficiency grading, a benefit which hardly withstand if you equate an indirect water heater with an extremely efficient furnace or boiler as the source of heat.
Moreover, as solar water heating is not applicable for many homes and climates, an indirect water heating system is really your finest bet while it comes to setting-up a heating unit that blends best hot water supply with energy-efficient characteristics.
In purchasing this indirect type of heating device, base it mainly on the Combination Appliance Efficiency or C.A.E. because it measures the efficiency of a combined water and space heating system. The standard C.A.E. would be 0.85 but the higher the C.A.E. the better.
If you are right now in the process of getting just the regular boiler, you may ask your contractor about installing an indirect water heater instead. This may cost you around $600-$900 just to install but they are expected to last for up to 30 years. Unlike the traditional storage tank type which may last for only up to 10 years. This indirect type of water heater is also highly popular in Europe.
