/diy/ - Do It Yourself

They're okay. Takes a while to get hot water in the kitchen sink.

apparently in england it's safe to consume heated water. are these units how they get away with it? still seems sketchy

>>2738010
>this scares the boomer
the price maybe.
the electric ones require an ass ton of amps for anything over 4gph.

>>2738010
They also terrify anyone who has hard water. They are much less forgiving of the 30+ gr/gal water around here than a tank water heater with a with a bendy heating element.

>>2738078
That's why you sell a whole house filtration and softener system to go with it. Major dosh.
It's just as easy to plumb for rich folks as it is for poor.

>>2738010
My boomer parents got one, they like it. My house had one which I replaced with a traditional tank style heater that uses a heat pump with a gas backup. Uses fuck all for power and still has hot water when the power is out until the tank is empty.

Riiiiight

You are aware that gas will burn without the presence of electricity, right?

>>2738013
>Takes a while to get hot water in the kitchen sink.
Yeah depending on how far away from the sink the heater is. lmaoeven
>>2738021
I have a 24kW for 2 and a half baths, two can shower in the same time and there is still enough headroom to wash hands.
My 30kW electric furnace and old water heater were right next to each other so I just swapped them around, installed a thankless and a heat pump.
>>2738078
It needs a softener, my first heater element lasted only 2 years, but got a replacement on warranty.
>>2738296
It can but the modern water heater wont start if it doesn't have electricity. Grandma had an old one that would maintain a pilot light and work without power, but the thing was from the 80s.
>picrel, the middle knob is a piezoelectric sparker like one on a gas range

>>2738296
>gas will burn without the presence of electricity
Aren't you going to be surprised during the next winter power outage!
That's not a fireplace you're looking at. It's a spark plug, a bunch of solenoid valves, fans, pumps, all driven by a computer. And if it is running, it fails safe (valves close, flame extinguishes) when power goes byebye.
If you don't want to freeze, I recommend getting yourself a nice little computer UPS and/or a DC power inverter (unless you're smart enough to put volts directly on the other side of the supply -- but based on your conduct thus far, I'd guess "no.")

>>2738238
Anon, it's a 55 gallon tank water heater. That water stays hot even if the power is out for about a day. It's still quite warm after two days.

I thought about replacing my water cyl with one of these, can they been installed outside?

>>2738406
>can they been installed outside?
Yes, but it is not ideal if you live in an area prone to below freezing temperatures.

>>2738360
>>2738335
you people are fucking retards they still water heaters without electrical connections, go outside

>>2738335
My gas water heater is about 10 years old and will run just fine without electricity. It uses a piezo electric lighter to start the pilot and bimetalic strips.

>>2738360
Most fireplaces and gas tank water heaters have a sparking ignititon switch like a gas grill

You are right about a gas tankless that runs 110v needing a power supply when the power's out

>>2738374
I misread that you were describing your tank water heater. Gomen nasai!

>>2738418
I may be a retard. But you're gonna be cold.

>>2738517
what are you even trying to say

>>2738010

maybe, but drilling a 5 inch hole into a joist for venting can clench anyone's balloon knot

>condensing boilers
gl when the electrodes wear out every two years, the plastic pieces wear out every 5, and the whole thing shits the bed after 11 unless you pay a premium for oem parts
just get a normal hot water tank and point the flue upwards, you'd be amazed how long they last

>>2738010
Power hungry shit. I'll take 200 liters + 2 heat exchangers + recirculation instead.
>>2738013
>Takes a while to get hot water in the kitchen sink.
That's cause you obviously can't have a recirculation line without some storage, lmao.

>>2738442
>>2738360
>If you don't want to freeze, I recommend getting yourself a nice little computer UPS and/or a DC power inverter
Most of them detect flame presence through ionization of the igniter electrodes and often require proper Live/Neutral wiring, they wont work if they don't sense the Neutral-earth bonding.

>>2738896
I check back on this thread and just now realize OP's thing runs on gas. Still applies, the heat exchanger can be connected to a gas boiler like the radiators. Recirculation is great.

>>2738908
I don't know about all that gobblygook you wrote but pc power backups from staples or office depot work perfectly well on Rinnai tankless water heaters when the power is out.

>>2738418
>they still water heaters
They do indeed.

>>2740530
lol I think he ment they still MAKE whatever he was talking about

My dad doesn’t want his pipes to freeze but doesn’t want to drip hot water cause he thinks it’ll use too much electricity, would it use a significant amount of energy to keep hot water dripping ?

hope you dont like HOT showers.

These are only capable of raising the water temp 30 degtrees above ambient...

Yeah, I wouldn't trust it for drinking but you can run a toothbrush under it unless you just moved in. Most houses have been retrofitted with these things over the past 20 years. Next scam is replacing them with hydrogen compatible boilers.

>>2738010
I just got pissed at my shop because our old one leaked and we had a tankless boxed up in the closet but the boomers went to home depot and bought a regular replacement unit. Guess you’re right.
