Does this Eccotemp draw much power? My camp is serviced with solar panels so I like to control what electrical appliances I have. Also I should be able to reuse the power vent that I have on my existing BOSCH water heater?

Asked by: billie60
1. The amount of electric power would be negligible. 2. You could reuse the power vent if you can connect it so that it starts when the heater turns on and stops when the heater is off.

Can this be used to replace the gas hot water tank in a mobile home?

Asked by: rick88888
We purchased this unit for a double wide permanent home and its works perfectly. It takes less space than the old hot water tank. Be sure to vent your closet door for sufficient air floor.

what is needed to install it besides z vent kit?

Asked by: Roger212
Save 200$. Don't buy vent kit. I'm used gaz vent pipe. Same like to gas furnace. Gas furnace use 2 inch pipe, and nothing wrong,have more power, like this water heater.Just installed reduser 4 inches to 3 inches. Use fire rated calking to connect to heater.after turn 90' 3 inches, and 3 in. ABC black pipe 2 feet long to go outside home.to end pipe connect turn 90' ABC Whit simple drain cover. Just need install pipe a little down. For protect condensation water doesn't go inside home. In Europe we use metal flexible pipe, little stronger like to dryer. And nothing happened. What is special in North America ? I recommend this water heater for middle size home. I have full bathtub, and shower , 3 sinks and have enough hot water. Good luck!!
