Aside from being available at a very good price, the Rheem 240V Residential Tankless Water Heater has a very good flow rate of 4 gallons (15 l) per minute. This means it allows the hot water to run in the corner shower and in the kitchen at the same time. Its dimensions are 9” x 4” x 13” (22.8 cm x 10 cm x 33 cm), so it can be easily mounted in a studio apartment or very crammed spaces. What’s also great about it is that it doesn’t use too much power when on (240V, 13 Kw).

Different from propane water heaters, the Rheem 240V Residential Tankless Water Heater doesn’t need to have any gas pipes or ventilation system connected to it. It allows the adjustment of temperature with 1-degree F increments and has a thermostat with a LED display on the outside for more control and an accurate read. Besides, it has a very interesting and modern design, which means it looks good no matter where it may be mounted.

User-friendly and easy to install, the Rheem 240V Residential Tankless Water Heater has 2 heating elements made from copper, a durable and very strong material. More than this, it’s made by a company that manufactures heating systems ever since 1925.

Rinnai Ruc98in Ultra Series Natural Gas Tankless Water Heater Review

Click Image For Latest Pricing

The Rinnai RUC98iN Ultra Series Natural Gas Tankless Water Heater runs on natural gas, so it cuts down the energy bill by a lot. While natural gas heaters owners complain about ventilation, this unit features 2 venting options: one that’s twin-pipe and another one that’s concentric-PVC so no need for an exhaust fan. The one that’s easier to install can be chosen, and the hot water will start flowing immediately. What’s also great about this water heater is that it can supply a large house, seeing it has a flow rate of 9.8 gallons (37 l) per minute.

Even if it has an impressive flow rate, the Rinnai RUC98iN Ultra Series Tankless Water Heater still doesn’t consume too much gas. As a matter of fact, its gas intake is from 15,200 to 199,000 BTU. The more gas is getting, the more it increases its water flow rate. Besides, it has a 0.95 efficiency rating, which means it doesn’t pollute the air and thus, is environmentally friendly. It should be installed indoors only, as it’s not made to resist harsh weather conditions.

The warranty on the Rinnai RUC98iN Ultra Series Natural Gas Tankless Water Heater is 12-year for the heat exchanger, 5-year for the parts and 1-year labor for residential installations. This means that if one of the parts covered by a warranty breaks in the specified time period, it will be replaced by the company for free.

Pros

Energy efficient
Doesn’t consume too much gas
Environmentally friendly
Suitable for larger houses
Good water flow rate
Heats the water very rapidly
2 venting options
Quiet

12-year warranty on the heat exchanger

When it comes to compactness, ease of use and a satisfying water flow rate, the Atmor Instant Tankless Water Heater is the perfect choice, not to mention that it’s available at a very good price. Another of its great features is its water sensor that registers when hot water is in demand and starts the heater to provide it. This means that as soon as the tap is turned off, the sensor tells the heater to turn off heating, this way bringing down the energy bill by much.

The Atmor Instant Tankless Water Heater comes with only one knob that’s underneath its digital thermostat and very easy to operate. Even children can use it without exposing themselves to any danger. As a matter of fact, the safety level of this heater is quite high, as its components are IPS4 certified. This means they remain dry at all times, so the risk of the unit to become damaged with time is greatly reduced. The heater also has a self-modulating system incorporated, meaning it delivers the recommended flow rate only when needed.

The temperature control on the Atmor Instant Tankless Water Heater is digital and can be set in increments of 1-degree F. This unit must be connected to a 240V power source and indoors only, as it’s not weatherproofed.

Pros

Easy to use
7-year warranty against leakage
Digital temperature control
Self-modulating system
Water sensor
IPS4 certified components
Easy to install
Saves energy
Stainless-steel interior
Durable

First of all, the Eccotemp FVI-12-LP Propane or Gas Tankless Water Heater is very compact. This means it can be installed in the tightest spaces and still look good. Another of its great is its 20 pounds (9 kg) weight, which makes one of the most lightweight tankless water heaters on the market. All this doesn’t mean that its flow rate is low, though.

The temperature is displayed on an LCD screen that doesn’t turn off. It should also be mentioned this heater is designed to be installed outside only.

The Eccotemp FVI-12-LP Propane or Gas Tankless Water Heater is also very easy to install. The 3 openings for the hot water, gas or propane and cold-water inlets on its back are labelled, so there’s no need to call a professional to mount it.
