I am considering changing out our 10 year old electric hot water heater with an electric tankless system... I don't have access to gas/or lp.

The benefits I see are that you only heat the water when you need it, and it doesn't sit in the tank waiting...

The thing I have trouble wrapping my head around is going from tank electric to tankless electric - it seems like a wash - i.e still using electricity.

Is there a significant savings in going to tankless... even if I select an electric tankless system.

I have the standard electric hot water heater which is pushing 13 years old. I'm noticing that it is not supplying enough hot water when showering, etc. Thinking of going tankless to save electricity and water, but I need to know how well they work. Any comments, suggestions, etc. will be greatly apprececiated.

More of an electrical question. I've got a new tankless electric water heater I installed myself. Being tankless, this uses a lot of power (6 AWG wire with a 70amp breaker 220 monophase). I've got it wired through an AC disconnect near the heater due to the thick cable.

Everything is fine and I'm quite sure I wired it up properly. However, with all that power I just want to be sure on the facts regarding electrocution danger with such a setup. I've got the ground wire properly connected. Not sure if this matters, but the ground wire is in very close proximity (maybe even touching the case) to the wires in the AC disconnect. I have plastic PVC plumbing in the house.

Given this setup, is there any danger that I could ever be electrocuted if this heater were to short out or malfunction or if that ground wire ever touched one of the hot leads? Can water in a plastic pipe even carry that kind of power? Thanks for any information!

I've heard that the On Demand WH will save me money in the long run. What kind of matinence issues would come w/ an On Demand set up? Is there a disivantage to the On Demand, out side of it being more expensive?

We currently have a coil that heats our water...and we take short showers and the kids get half a bath. We were considering adding a tankless hot water heater such as "instant hot" to our gas or a water tank like "super stor ultra" to our oil burner. I'm wondering if a product like instant hot will really give an endless hot shower and fill the tub too. I'd appreciate feedback/experience with this.

Our 17 year old water heater broke. We really want to get a tankless now to replace it. We can't easily run power out to where our water heater is now so we need a new one that does not need power. The Tankless needs to run on propane and be able to be outside in a small shed on the back of our house. We only need one to run 1 shower at a time since we are a small family. Any suggestions? Do you use one and are they are they worth the money?

I have a limited closet space for installation of this unit.
Are there other brands with a similar design?

Sometimes it works and sometimes it doesn't. Have to turn it on and off several times to get hot water. Home depot says mother board. But they don't know how to test it. Unit is Richmond.

have experience with these? Are they worth the extra cost?

I would like to know about them and if they work good or not. I hear the gas ones are great but tell me about the electric ones. we have kids and 2 bathrooms and like hot showers. do they put out hot water? how about your electric bill? what kind do you have? what do you recomend? Thank you

Hi

I was worrying if someone could help with a problem that seems to have foxed a number of plumbers.

I have a Valiant Combi Boiler (VCW T3WF Type C) which is behaving very oddly. The pilot light stays on but once I turn the hot water demand on, I get hot water for approximately a minute or so before the pilot switches off and I have to re-light the pilot.

I've noticed that the time that hot water is delivered is gradually diminshing (quite irritating when in the shower or mid way during a shave!).

I was wondering whether anyone could shed some light on possible causes.

Thanks in advance.

I need a new water heater, I don't feel like giving myself a headache to save bucks. What is a good deal for a hot water heater. I will probably install myself to save 0 unless I get some help. What is the payoff on a tankless water heater, i.e., the difference in price versus the savings on a yearly basis (or a similar ratio). I'd like somthing durable; it seems like I'm always replacing water heaters every time I move.
Lowe's is closer, but I will drive to Home Depot if I think it is worth the trip.
