ELECTRICAL REQUIREMENTS FOR AN ECOSMART ELECTRIC TANKLESS WATER HEATER:

Before purchasing an EcoSmart electric tankless water heater, please make sure that your home has sufficient electrical capacity for your desired model, or that you have taken note of any upgrades that may be required. In order to ensure your safety and qualification for the limited lifetime warranty, a licensed professional must install your system. Please refer to the chart below for electrical requirements: http://www.ecosmartus.com/support/electrical-requirements/ [ecosmartus.com]

ELECTRICAL REQUIREMENTS FOR AN ECOSMART ECO MINI 4 | 4 GALLON ELECTRIC MINITANK: http://www.ecosmartus.com/products/eco-mini/eco-mini-4/ [ecosmartus.com]

ANYONE WITH ANY EXPERIENCE/EXPERTISE REGARDING INSTALLATION OR REQUIRED VENTILATION FOR UNITS PLEASE KINDLY ADD INFORMATION HERE.

If you have hard water, or water scale I recommend installing an Aqua-Pure AP430ss or similar in front of the ecosmart.

Most residential homes will not have the required electrical service to run those 2 whole house water heaters. Check your service before you buy.

Hmm, that little one is tempting, assuming I had the money to spend. Seems like installation would be extremely simple under the kitchen sink. If we were planning to live in this place forever, I'd do it, but the next owners can install it if they want. Smilie

Unless you already have something similar installed, it's probably a safe assumption that anyone will need an electrician to install new breakers and possibly run a 240v line. At least it's a little easier than installing a gas one, since I understand that those require ventilation which can be quite extensive depending on where the unit is located in the house.

I thought about going tankless (I have a new gas water heater sitting in my garage right now), but there's too much downside. If I were to do a new build though, tankless would be my top choice.

Its not just some 240v lines. You're entries service would have to be upgraded.

Wow, you're not kidding.

4, 40amp 240v breakers for the one unit. Very few homes have that much extra capacity.

I have the geospring hybrid water heater. Runs on standard 30 amp 240 volt breaker. It helped that my local utility had a $400 kick back on one. On demand electric water heaters are not any more efficient than a heat pump model.

a lot of incorrect info in these posts. I have an electric tankless so I speak from experience.


the middle one uses 3x double pole breaker (6 breaker spots) and the larger one uses 4 x double pole breaker (8 breaker spots). so you do need to have that many empty spaces in ur box. if not, u can add a sub-panel which is easy and not that expensive (that is what I did). plus if ur box is almost full u should probably be adding in a sub-panel for future use anyway.


the 240v is nothing more than 2 x 120v (hot leads combined) which EVERY HOUSE in the USA has. ur A/C and electric ovens / ranges all use the exact same 240v lines (2 x 120v).

yes there are downsides to going tankless, but in the long run tankless is a much better option. why heat water 24 hours a day when u use it less than 1 hour per day. plus just about any tank u buy from a big box store (GE, Whirlpool etc.) is total crap. Price out a decent tank (Rheem, AO Smith etc.) and the initial price expense is much lower than u would expect, even with the potential extra electrical costs. and yes a gas based system should be done by a pro.


I do recommend adding in a set of water shut off valves at the heater (again very inexpensive). years down the road when it eventually wears out, it would be a really easy DIY job to replace it. just shut off water (using the valves) , turn off power, unplug the old one, put new unit in place, attach wires and water lines, turn power and valves back on. job is done.

the house has it. but are you going to install one in the kitchen and not use the oven?

Also, if you're getting a gas model, there's a good chance you already have a gas furnace. You can tie the exhaust into the furnace exhaust so it's not overly complicated. At least consulting a professional would be worthwhile; or at the least, monitoring for high CO for a bit right after you finish installation.

Any gas lines would need to be run by a licensed plumber, from what I recall in my old house (current house has all electric.....for now).

leave the oven breaker as is. take 2 empty breakers, those leads attached together will make a new 240v breaker.

I already have one of these installed as a whole house heater - does anyone know if we can add another in series (not power, just plumbing) to increase water temp. ?
