A Few Things to Know About the Tankless Water Heater
The popularity of the tankless water heater has certainly grown because such heaters just heat when it is required allowing better energy efficiency over the counterparts. Such type of heater doesn’t store in a vessel and such is able to supply that unlimited amount of water to the faucet. The heaters having energy efficiency of more than 80 could make the buyer qualified for $300 federal tax credit.
You have to know that the tankless heaters don’t start to heat up until the tap is actually turned on and there is also a delay of one gallon prior to heating up and this occurs every time the tap is turned on whether this is used or not. Moreover, the heaters may be twice as expensive as the tanked option and the possibility of making this expense back in the energy savings. You must also be aware that installing a tankless system in some situations can be difficult and some of the gas units may require wider vents and gas pipes in order to run the meter for the unit which can also increase the installation cost and you should know that having them in a holder home can be hard to do as well. Also, this can take a lot longer for the hot water to reach the remote rooms of the home through the use of the tankless water system.
A great thing when it comes to the tankless water heater is that one doesn’t have water storage tanks and this is why it is quite energy-efficient. There is no standby heat loss as well as no energy is being wasted in the tank like the conventional system. Moreover, they can be point-of-use heaters or a whole-house unit. You have to understand that the point-of-use models just heat where the unit is installed as opposed to the ones which heat in the entire house.
Know that the flow enters the unit and is then being heated by the heat exchanger. The heat exchanger is either electric resistant heating coil or can be a gas fired burner which use propane or natural gas. This is a typical whole-house model and the gas units have more heating capacity unlike the models with electric-resistant heating coils.
When you are going to choose the size of the water heater, there are three factors to consider like the cold temperature entering the unit, the volume of water needed and the hot temperature desired. This would require the size, type and the number of the tankless heaters that need to be used.
You should understand that the point-of-use heaters are made to just heat where they are actually installed. Also, they are actually smaller units that fit under the sink, inside the cabinet or in the closet that serves just one faucet, sink or shower. These are less expensive models that cost only a few hundred dollars before you add the expense of installation.
