Here are the tips you should know on getting the perfect heaters based on your customized needs.

1. Flow rate

If picking out the primary essential factor in selecting a water heater, it must be the flow rate. To size the desired flow rate, you should determine the maximum devices runs at the same time, adds up the flow rate of each device and that is the final total flow rate you need.

For example, if you intend to get an electric 110v heater to run two faucets at the same time; the single faucet, let’s say, has the maximum flow rate of 1.5 gallons, then you will need a heater with at least 3 gallons to support enough hot water for your needs.

2. Usages

Where do you intend to use the tankless water heater? Whether for an under sink use or whole house use, for indoor use or use it outdoor as a source for car washing? Determine the usages of the heater is the per-step of calculating the exact flow rate and measuring the sizes.

For under sink use, the small shape is what demands. You won’t want a large point of use heater to occupy much floor space. If you attempt to use it outdoor, then portability is the key one should consider before buying.

3. Temperature rise

The temperature rise determines the maximum flow rate one tankless water heater produces, referring to the difference between the set temperature and that of incoming groundwater.

For instance, if you set the unit temperature to 130° F, and the incoming groundwater being 60° F; then the temperature rise should be 70° F.  This can get tricky, because heaters can say 70 degree rise on 1 GPM, but you need 2, then technically you really only have 35 degree rise.

4. Quality

The quality level of an electrical device is what you should always pay great attention to. It determines not only on the service life of a machine but more importantly on the safety in use. Apart from heavy-duty materials, such as stainless steel or metal, some of the highly advanced machines are equipped with protective devices, like auto-shutoff or freeze protection, to protect the unit from burning unintentionally.

If possible look for a unit that has replacement heater elements available when elements might burn out.
