Question DetailsAsked on 2/26/2016

I need an experienced installer of electric tankless water heaters--in existing house, not new construction.

I believe I would like to have an AquaPower DHE 12 installed in my one-bathroom home. My existing conventional water heater is run through a double 30 amp breaker. Will this tankless option work for me in South Bend, Indiana? Low-flow shower and hand/dishwashing is all I need; no dishwasher. Who can install it for me (plumber or electrician?), and for what price? I have a Michigan basement with masonry walls.

Heating and A/C would be the normal Search the List category for this - some plumbers also install them but generally would require you get the wiring done by an electrician, whereas a lot of HVAC providers have an electrician either in-house or on-call so can handle it all.

Note a lot of these units take 40 to 60 amp 220V breakers - though for a single-bedroom home with low-flow shower a 30A unit might - just might - suffice. The DHE 12 you are talking about needs a 220V (double) 60A breaker so twice the size of your water heater, and the main panel has to have a minimum capacity of 100A on the main breaker - though if electric range or dryer or electric hot water/steam heated dryer or dishwasher will have to be well above that, so your entire distribution panel size may not be adequate for this unit as is, which of course can crank the cost up a thousand or two (rough ballpark) if your main panel or service needs to be upsized to handle it.

Installation cost should normally run about $1,000-1,500 assuming power and water connections are reasonably nearby, based on labor time involved to typically install one. The unit itself is $400-500 retail cost. Actually commonly bill out at $5-10,000 or even more installed (I have recently seen billed as high as $14,000 for an under $1000 retail price unit) because people have been suckered into believing these units should be expensive because they are supposedly (commonly not so much) very energy efficient.

Check with several vendors who have experience installing this type unit - there is likely to be a WIDE spread in pricing.
