Choosing and Installing Tankless Water Heaters
Tankless electric water heaters are a great energy efficient alternative to other models. The first thing you must determine is your hot water needs. In general, the flow rate of smaller tankless electric water heaters can support a bathroom and a kitchen with a dishwasher. The main thing to gauge is the flow rates of your fixtures and the amount of water you will be using in them. Tankless models can also be installed by water zone for families with higher usage rates.
An important part of finding appropriate tankless water heaters is to understand your dishwasher and clothes washer. Some newer washing machines have the ability to heat water themselves, and therefore will not need to use water heaters. Your dishwasher may be an energy efficient model that only uses a small amount of hot water. If you aren’t sure about your water needs, it’s always smart to work with a professional to determine the size of water heater you need.
Since tankless electric water heaters immediately heat water ran through them, it’s best to place these close to the faucet. Avoid long runs between the heater and the faucet. Tankless water heaters are somewhat difficult for the average person to install, so finding a contractor to help you is usually the way it’s done. Provide the written instruction from the water heater to the contractor. You may also want to consult the manufacturer’s customer support department for added tips.
When installing tankless electric water heaters it’s important to make sure you meet all building codes. If any small details are overlooked during the preliminary reviews, you may have a messy and costly fix to attend later. Many building’s department staff are up to speed on tankless electric water heaters, but some are not. Prepare yourself for confusion and long permit reviews before you can begin installing your tankless water heater.
Because tankless electric water heaters are small in size, about the size of a briefcase, their versatility in where you can place them is high. Under sinks, in closets, or in garages are common places to put electric water heaters. In warmer climates, some may even install the unit outside. They can also be fitted with small electric heaters to prevent the heat exchanger from freezing in locations where freezing temperatures are possible.
Tankless electric water heaters do not have a reservoir, but instead work by instantly heating water that is flowed through it. A sensor triggers the heat exchange and provides the faucet with instant hot water. These electric water heaters do not need to be in a well ventilated area because they give off no greenhouse gases and need no clear air intake. Tankless electric water heaters are available in a variety of capacities and are available from numerous manufacturers. The maximum flow rate of these waters heaters are determined by the capacity. Determining the placement and size of tankless water heater you need is easily assessed by a professional. Always make sure safety precautions are taking when installing these units.
