Whole-house & point-of-use tankless and mini-tank electric hot water heaters in hardwired and plug-in options for a variety of residential and commercial applications.
Types of Electric TWH’s
Whole-house tankless units are intended for whole-house, multi-fixture applications and offer better functionality than their POU counterpart.
Point-Of-Use or "under-the-sink" electric tankless water heaters are compact units designed for single-fixture use, most commonly for a kitchen, laundry, bar or bathroom sink. They are inexpensive and very compact, but often lack advanced functionality, such as temperature adjustment, modulation, etc.
Mini-tank electric water heaters are not considered true "tankless" since they incorporate a small storage tank. However, due to their relatively small size, they are also classified as under-the-sink water heaters and are intended for single fixture applications. Most of these are 120V plug-and-play type, which means no complex wiring or piping is needed.
Sizing an Electric Tankless Water Heater
Sizing for each of the above-mentioned water heaters will differ and we suggest visiting each page for particular details.
In general, all tankless heaters work based on a principle where the unit will add a certain amount of heat to the water flowing through it. The higher it's wattage - the more heat can be added. This number is dependent of two main factors - incoming water temperature (cold/groundwater) and the flow of water through the unit. Some (whole-house) units will prioritize the outgoing water temperature over flow rate, and can limit the flow to meet the desired temperature. Others (many POU's) disregard flow and only add a fixed amount of heat, either requiring a flow limiting device (often included) or leaving calculations fine-tuning of the end user.
Availability (uptime) and abundance of electricity are also important factors, especially for whole-house units, which usually require 208-240V power supply and several dedicated high-amp breakers.

Why don't we show the price?
While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
