   Need more information.Natural gas,Propane,or Electric?New construction or existing building?Older house 100 years old or house 20 years old?Basically electric models take too much electricity to be efficient.They can be used in smaller applications like for one hand sink.Natural gas, Propane models Install like normal tank heaters,But they require larger Vent pipes and larger Gas supply lines.In a new house that is being built these increased sizes can easily be installed.In an existing house it will be much harder and more expensive.Tank less systems use about half the energy normal tank heaters use.They are much more expensive than standard systems.Can take 10 to 15 years to pay for itself.I installed one in a remodel last summer.1,500 to 1,700$ in parts,1,000$ labor.The customer likes it.This model has a .5 gpm minimum.No complaints of no hot water at low levels of use.You do have to run water for 8 to 10 seconds for hot water to come out.This is wasteful but no worse than other systems.If you want to be green and energy efficient get one of these systems.If you want to save money get a standard system

   We had one of these and I did not like it.
   You install just like a normal water heater. Hook up water intake and outlets, and either hook up gas or electric to the tank.
   The thing about these – we had a gas tankless. When the water flows thru the water heater, the gas comes on and the water runs thru copper pipes through the wall of gas flames. In order for the flames to come on, the heater required a certain volume of water flow (like 2 gallons per minute). When my spouse takes a shower, he likes it steaming hot, so he has the hot water running full blast. When I take a shower, I want it barely skin temperature. So, when I turn down the hot water faucet to the minimum, the flow rate is too low to start up the flames. I ended up taking either ice cold showers, or way too hot for me to even stand under the shower head. There was no in between. We even went to the trouble of changing out the shower faucet handles to one hot and one for cold (instead of the one-handle kind you have to move back and forth to regulate the temperature). It still did not work. To get the low flow rate I wanted, the tankless would never come on. We pulled it out and put in a larger normal water heater. It’s sitting in a dusty corner if you want it.

   This is a tough question. There is nothing different or any additional plumbing needed. Just the electric is different. You need 2-40 amp circuits compared to the 30 amp its on. This may take up to 6 hours to run the whole thing. Actually there is not enough info here to make a decision on how long it will take. Check with your local hardware store and/or a plumber/electrician.

   Our hot water has been out in our apt building for 5 days now, so I think someone in a wheelchair is trying to install ours in our case
