We have no hot water: help decide what water heater system asap.
Comments (9)I installed it all and plumbed it myself - Not a really difficult job . . . . maybe 3 on a scale of 5 The collector panel was $1K, the tanks were $600 for the pair, the circulator pump was $100, the differential controller was $200 and about another $300 for copper piping, valves, flowmeter and an analog temp guage. $2200 for the total system, give or take $100. We had no hot water heater to begin with, so we would have had to spend $300 anyway, so take away the $300 and the $400 in Tax rebates and the system actually cost us $1500 - I got $300 off my federal income tax and another $100 from the state My 'break even point' is about 3 to 4 years - It would be higher if I had paid another $1500 to $2K for a professional installation We're remodeling an old farmhouse, so we've never lived here with anything but the solar heat but the tag on the side of one of the water heaters says it costs $400 per year to run - It's a very high efficiency unit with 3 inches of polyfoam insulation, so a lesser water heater would cost more to operate. $500 to $600 per year is probably an average cost for domestic water heating per year for a family of four I REALLY don't understand why there isn't a larger push from the government on solar water heating. Unlike solar electric, or hybrid cars, this technology is pretty well perfected right now and the payback is much shorter than for just about any other 'green' energy source. It can be used in most places in the United States. The outside temp isn't a big factor in how well it works . . . . it depends more on how many sunny days you have If more houses had solar domestic hot water systems, we could make a huge dent in the total energy use of the country and just think of how much less fossil fuel we would consume Don...See Morewater heater, tankless vs tank, propane vs electric
Comments (0)I searched GW for this topic, read through pages and pages of threads and I'm still confused. I don't understand the technical talk on the debates for each side and need to decide ASAP what's best for our house. Just when I think I have a decision made, I read something that changes it. From what I'm gathering, many people like tanks because they're simple, easy to repair if needed, and less expensive upfront. People dislike them because they take up a lot of space and can run out of hot water when people are using hot water simultaneously. People seem to like tankless water heaters because the hot water is unlimited, they take up less space, and are the "future" of water heaters. They seem to dislike them because they're more expensive, are complicated to fix, and don't always work out the way people expected them to or how they're used to using a WH. We live in E. Tennessee where the climate is moderate but we tend to have ice storms that cause power outages in winter. We are a family of 4-two adults, a teenager, and a baby. We have relatives come visit often and may soon have a family member or 2 staying with us for an extended period. We have 3 bathrooms with plumbing roughed in for 1 more in the basement. Basement is unfinished but has a large designated mechanical room so space is not an issue. We have a propane tank for the cooktop which is large enough to also use for a WH. Our GC suggested a good ole large capacity tanked electric WH. I trust him but I also realize that he's been doing this for 40 years and he goes with what he knows and trusts. He said if we went tankless we should go propane instead of electric because of how much power it would use. He mentioned putting something under the sink of the 2nd floor bathroom to help the hot water heater distribute water faster/more efficiently from the basement upstairs. He didn't use a name for it but I'm thinking maybe he was talking about a circulator? Anyway, any input would be greatly appreciated!! Need to buy soon so we can move in....See Moretankless water heater--where to hide the "hot button?"
Comments (10)Thanks everyone for your comments. (And thanks Greg for confirming I’m not crazy since I didn’t see a wire and....it just seems odd on the back of a door). Yes, I want to save water. I live in CA and in past years we’ve had water restrictions. I‘ll be waiting for hot water to arrive, whether the tap is running or not. Also, someone I know says she can hear hers when it’s running on schedule. Why listen to it heating water that I don’t need? Plus, as Lawrence pointed out, I‘d save energy vs. the scheduled recirc. FWIW, I had assumed that I could schedule and have these buttons supplement it but when I was researching yesterday, some website said it was an either/or thing. Seems like very poor design. Maybe they fixed that. I guess if I hate the buttons I could always use the schedule feature like normal people. ;) Jake, were you joking about motion detector? I.e. every time I walk into one of those rooms it would kick on, even if I don’t need it? Lawrence, funny you should say “Can you imagine having to find your phone...?” Yes, I did try to imagine it LOL and thought low-tech was the way to go (as long as I could hide these buttons). Another aside: my plumber offered the option of installing a water softener. I don’t like soft water. So I’ve been researching other options to avoid the mineral build up. My thoughts: flush regularly (maybe more often than recommended). Also, use this hot button so I’m only heating the water I actually need to be hot. So I guess I’d be using this as a whole house water-on-demand system. Maybe I’m weird (?)...See MoreWater heaters tank vs tankless
Comments (15)I like tankless heaters, I installed them in the last two houses. But there are things to understand about them: 1. Tankless heaters are very expensive to install when done as a retrofit. 2. They take an extraordinary amount of gas at one time - so you have to have the gas supply. Having the supply to run two of them would be unlikely. 3. They do take longer to supply hot water. 4. they do need regular maintenance So again, let me suggest a hybrid electric heater. These don't require venting at all. They cost less to use than even a tankless heater. They will cost much less than a tankless to install and there are often large rebates from the power company. In addition they will dehumidify your basement. They will give you hot water faster. There is an 80 gal available rather than installing two....See Moredadoes
