Types of 5 GPM Tankless Water Heater And Their Common Features
The 5 gallons-per-minute water heaters are available in various kinds. Below are some of the top kinds and their corresponding top features:
Electric
As the name implies, the electric heater uses mains electricity to supply its heating power. It is quieter, cleaner, and very convenient to mount and engage. On the flip side, this kind of heater is costly to engage in in the long run. That is because it inflicts higher levels of utility bills.
Gas
This one draws its power from liquefied petroleum gas. Its heat output is subsequently higher and hotter. Yet one more advantage is the fact that it is capable of mobile applications. It is hence suitable for remote applications such as picnics and camper water heater. Some degree of care is necessary though as gas is ordinarily dangerous.
Propane
Propane is even hotter than the liquefied petroleum gas. It has the added advantage of being packaged in smaller bottles that are easier to transport out and about the desired area. This is the kind of heater you want to leverage if you are constantly on the move.
Hybrid Electric Water Heaters
These ones derive their heating power from both electricity and ambient temperature. They hence bring along the convenience of being usable all round regardless of the prevailing environmental temperatures. Their energy efficiency is also higher (approximately 60% more than its counterparts.) It is a good one to use in your home.
Solar Water Heaters
Solar water heaters derive their heating power from the sun. They are the most environmentally friendly of all the heaters we have around. Then, their long-term costs of operations are also lower. However, they are only limited in applicability to those times of the year when there is plenty of solar energy like summer.
Condensing Water Heater
The condensing water heater is a special kind of tankless water heater. Unlike your ordinary heaters, this one draws its heating power from the unused gas of your home. It is thus more effective than the many other alternatives. Moreover, it also saves you money by utilizing every drop of gas in your home.
Can I Use a 5 GPM Tankless Water Heater for Whole House Use?
YES, you can! However, there is a catch. It is sufficiently capable of powering only a modest home with no more than four occupants. That is because it does get stretched and overwhelmed when there are more users in the home. Thus, you have to ascertain just how many people might need it in the long run before embarking on a purchase.
Then again you have to consider the structural makeup of the appliances in question. A heater that is used by many people tends to wear out too soon. If you have many people in mind, you have to insist on that one that is strong enough. It has to preferably feature the stainless steel material makeup.
