I am considering installing a Tankless Hot water heater here in the next few months and was wondering whether or not I would have to switch part of my lines over to copper. Anybody installed the electric version of a tankless system and have problems? Thanks
First, DakotaWayne I am a bachelor living in a two bedroom, one bath trailer with a dishwasher and sink (neither get much use) and a washer and dryer. So its not like Im living in a 5 bedroom house with 10 kids. Second, I am a little bit old school so I call CPVC "PVC", you go to Lowes they are going to give you CPVC because they know what you mean. Just letting everyone know my living situation.

I am looking to replace my existing hot water heater and I don't want to go tankless.

I have to get a new water heater soon. I saw that their are new tankless water heater, but they seem that they would cost more to run because they are electrical, where a traditional water heater runs on gas.

My oil-fired baseboard heat furnace (I live in CT) also makes the heat for hot water via a domestic coil. To do this, it stays hot all of the time, 24-7 regardless of temp outside. It's 176,000 BTU and ends up using a full 275gal tank of oil (currently at 4.15/gal) during the summer months. I have accidently hit the emergency switch at night to find no heat the next morning for a shower, but after flipping the switch back on, we have hot water in less than 5 minutes. Is there a way, and is it safe, to shut the beast in the basement off during the night hours (say after 9pm) and have it stay off until a set time or possibly until it detects water flow in the hot water pipe? For that matter, would I be able to have it shut off all the time (in summer of course) and fire up only in on-demand hot water situations? Please ONLY answer if you have valid infomation on my question. Thanks!

My only option is electric and was going to use a regular hot water tank but was wondering if it is possible to use an electric on demand water heater?

I can't use Tankless gas so I really want to compare between these two.

My wife and i just bought a house. the bath tub upstairs, when you turn on the hot water it takes a minute to get hot and then quickly runs out and gets cold again. we have an on demand hot water off our hot water furnace. every other faucet in the house runs hot water no problem even the sink faucet in the same bathroom ast the tub. HELP!!! very frustared new homw owner:(
The hot comes from a coil in our hot water boiler...im sorry i m not very handy and i dont know alot out boilers

We have just recently moved and our gas company says it will take a month to hook up a new service line. Can I convert to propane and where do I get the parts at?
Also, what parts do I need to get?

i have 3/4 inch piping about 40 feet from meter. also on gas are furnace and dryer. neither of which are used that often. Currently i have a 50 gallon tank water heater but want to go to tankless because it does not give me enough hot water for my japanese soaking tub.
