Water heater for Showers

[travajante]

Reviving this thread. Sir, would you recommend to use the PPR pipes (white) for all the house piping system or the blue ones will do for most and just use the PPR for those which will be used for hot and cold water?

Don't rely on pipe color, sir. Different brands can color em differently, some green, some white, gray, yellow, etc. Go into the specs. Seek those that are for hot & cold app. I recall years back the Ph distributor of Polymutan(Germany) carried a budget PPR brand for COLD app ONLY. You'll know by ocular. COLD ONLY pipes are thinner while the thicker Hot&Cold pipes mostly are marked w/ a red line lengthwise. Please note, sir.
Hot&Cold(w/ red) is thicker...

Thanks, sir. Will take note of these indicators.

Anyone familiar with repairing water heaters? Theres a leak coning from the inside of the heater, maybe I can DIY it before calling the service center.

personally,
i'd rather not.
i am wary of DIYing these things, because the water is so very close to the electricity...

Mark where the leak is then remove water heater so you can have a better look at it ... probably just a gasket leak ...

Gud pm guys. Mas matipid ba sa kuryente if tankless shower heaters ang ilagay ko instead sa mga may tank for two bathrooms and for shower lang naman?

pag ang leak ay nasa mga screwed joints lang, just re-tighten those loose connections.
pero pag ang leak ay within the confine of the copper tubing parts, kailangan na ng "expert" dyan. brazing is required, yung mga gumagawa ng aircon o radiatior ang kailangan mo. replacement is the easiest way out

Ayos ma sir. Simple fix lang, less than 5mins nagawa na nung servic center. May lumuwag lang from the plastic part due to high pressure daw. Realign lang and tighten the part ok na ulit

i googled it. you should, too, po.
interesting read.
pros and cons.

He probably googled it already and asked the forum because he wants opinion direct from members as with all other members na nasabihan ng google it.

i recommended he do the googling,
because the google articles were a bit complicated. they presented things that the post-er might have neglected to consider in the decision-making process.
reading his query, he appeared to be homing in onto the cost of electricity alone.
i wanted him to see the possible twists and turns in the decision-making process, that i felt google was better at imparting than i could ever do.
i think you already know how much i love to talk. but as google does it better, i'll give it to google.

however,
my personal opinion is,
"have two independent heaters."
it's simpler, and if one breaks down, you can still get a hot bath in the other 'room.
having only one heater... the heat needs of the two baths may not be the same... at least, not in the short run.

He he he. You got my point sir. I want views/opinions from those who have it here sa forum. Mas better parin talaga actual experience from fellow users.

Yes, having two separate ones would be better

there are heaters with design capability to power more than one gripo.
we have one such.
my problem with this, is that the temperature needs of the two gripos may differ, and the temperature control is not within easy reach from one outlet.
for this type of heater, gripo output temperature depends on flow rate, kasi.

yup. kaya i think it would be better if per shower has its own water heater. adjustments would be per user depende na sa desired temperature and within easy reach. pero what if the two bathrooms paminsan mahina ang water pressure? i read somewhere na its better to have a mechanical type one sa heater kasi hindi pressure dependent. and if this is the case, kelangan ba ng water tank kahit maliit lang to augment the needed water pressure for the heater to function properly?

Re: on demand heaters kung sobrang humina ang pressure di lang gagana yung heating element. Most good brands have that safety measure built in already. Mas matipid yung on demand vs ones with a tank kasi walang heat loss masyado at yung ginagamit na tubig lang ang iniinit vs water in a tank.

One advantage lang na nakikita ko sa heater na may tank is baka mas consistent yung temperature pag pabago bago yung pressure. Unless you have a constant pressure system, yung on demand heater tataas yung init pag may ibang gumamit bigla ng tubig. Pag bumaba masyado yung pressure dahil maraming gumagamit mawawala naman yung init dahil doon sa built in safety.

Power consumption? Realize that on demand, flow controlled heaters are mostly 6-8kw & require good working pressure. Small storage ones like those made by Ariston are mostly 2kw. No pressure required, just water & power. Both types will deteriorate w/ hard water, but the latter, due to its simplicity, will serve relatively longer....much longer.
Having had experience w/ both types, I'd vote individual Storage Type installed on the exterior of bathrooms. Why exterior? Ease of service access. Having them close to hotwater outlets will save both water & power. No hot water wait time. To save more? Have the heaters connected to a relayed switch per bath & w/ an assigned ceiling light as its pilot. One 8gal storage heater can serve 2 adjacent baths & can be lined w/ two 3way relayed switches w/ individual pilot lights each bath. Turn it on 5mins prior to shower, turn switch off right after. Not on demand, but will save you....electricity, heater replacement & maintenance costs.
Long had it w/ OnDemand. Water in our neckodawoods is Chicago hard. Yes, they're pretty, they're compact, but they're no match vs. storage in service life; & for as long as these are switched on only upon use, savings, too.
The fugly loyal(plastic shelled) storageYou can conceal its fugliness in a heater garage. Here, we element-proofed 1 in a shelter w/ aluminum louvred doors. No rust worries.

How long does the 2kw motor run though bro? To keep the water hot. The on demand ones' run time is only a few minutes per shower.

I can't finish a 4gal storage per shower, good brother. My routine? I turn heater on, 1 light goes on w/ it...brush my teeth, shower...I'd already get good heat that soon. 5mins, I'd say. Due to its limited storage, water heats up fast & remains hot even hours after heater has been turned off. My showers are quickies tho...I don't do much else in the shower, but shower.[emoji16] Once done, turn the heater off (pilot goes w/ it). That's it.

A lot more efficient than I thought then. These things are substantially more expensive though. And there are on demand heaters with about the same power consumption already.

If you don't mind bro, do you do a lot of high end projects like hotels? I noticed most of the stuff you recommend are on the higher end of available options.
