Some Interesting Tankless Water Heating Venting Tips
The selection of a tankless water heater is without doubt one of the most important decisions a homeowner has to make so as to lower energy consumption and decrease utility expenses. Once the selection has been made, then the decision on how to vent the heater should then be made. Typically, tankless water heaters require special venting so as to efficiently blow hot exhaust gas outside where it does dissipate. Unlike the traditional tank-based water heaters, these tankless options tend to offer the homeowner more versatile venting options.
As a matter of fact, current advances in unit design have made the installation of energy efficient tankless water heaters more affordable, more attractive and much easier to fit within your home plan whilst saving you space. Generally, this type of water heaters are vented in 2 (two) ways: power vent and direct vent. Power vent units must be placed in a larger area for adequate air quantity so as to enable combustion. On the other hand, direct vent units usually pull in air from the building or outside and have two vents. This simple configuration does make it possible for the tankless units to fit in smaller spaces.
Thanks to the self warming and automatic components, tankless units can be installed outside in warmer climates as well as in areas that are below freezing temperatures. Because they can be installed outside, they allow homeowners to free up indoor space which may be at a premium; this is especially quite pronounced if you have a mobile home. It is also worth mentioning that if the unit is installed outside then there is no need for venting.
It is important to note that the general design of a tankless water heater does allow for multiple venting options. They can easily vent through a side wall or roof. This does create more flexibility and options for placement. Unlike traditional gas tank water heaters that require venting through the roof, the tankless water heaters usually uses fans to blow exhaust from the unit horizontally, thereby allowing vents to be terminated on the side of your home.
To further lower the cost of installing a tankless heater, you can have it condensed. Non-condensing units typically transfer to the water not more than 80 percent of the heat that they have generated. The remaining heat usually develops a hot exhaust gas which requires metal venting; this usually comes in the form of thick aluminum or stainless steel. Studies have shown that units fitted with condensing technology are very efficient, up to 95% more efficient than non-condensing units. They also tend to emit comparatively cooler exhaust gas at around one hundred and ten (110) to one hundred and twenty (120) degrees. Because of this, the exhaust vent can be made of other materials other than metal such as polypropylene or PVC. This simple feature does significantly lower the overall cost of installation.
In addition to the above mentioned tankless water heater venting tips, opting for a unit which has adopted the concentric vent design does offer lots of additional safety advantages and benefits to the homeowner. A simple 5 inch concentric vent does contain both out-take and in-take pipes which make the vent cool to the touch since all the warm air is insulated inside the pipe. In such a scenario, if a pipe develops a leak due to one reason or the other, the air will stay in the concentric vent and therefore won’t enter your home; this is bound to give any homeowner some peace of mind. Another major advantage is that with only one pipe, installers only require one penetration in the ceiling or wall.
There are also units which come with recess boxes. These boxes come in quite handy since they can be used to fit the unit inside walls and not have them stuck on the home exterior. This configuration is ideal for those non-condensing tankless units which would otherwise pose a challenge when fixing. At fourteen inches wide, most non-condensing units can easily fit between conventional studs. If you opt for the eighteen inch wide condensing unit then you may have to come up with more creative framing ideas so as to ensure that your water heater is flush with the exterior of the house. In addition, more creative termination points and covers are also available so as to ensure that every homeowner gets an aesthetically pleasing venting solution.
