Residential water heating systems [Merged]

[shadow]

sino meron o nagpakabit sa bahay??? malakas ba sa kuryente? nakakita kasi ako sa MC homes last sunday... balak ko lagyan kahit yun mga showers lang, kahit hinde na yun mga sink.... kasi parang mas mura siya kesa bumili ako ng individual na water heater for the showers

[BlueBimmer]

kng gs2 mo mas tipid sa kuryente, kuha ka nung Champs or any brand for centralize pero not much bigger than individual shower type heaters. para it will provide heater for all ur bathrooms 1 at a time. tank-type heaters mas lakas kc sa electricity.

[shadow]

how much yun champ? so ibig sabihin bili ako nung regular na shower heater for each of my bathrooms? so 5 bathroom namin bili rin ako ng 5? hind eba pareho lang lalabas ang gastos?

[BlueBimmer]

1 lang po bibilhin, bale same size sya nung mga shower heaters pero for centralized ang function nya, meaning sa kanya dadaan lahat ng HOT lines ng bathrooms mo. for 5 bathrooms i recommend mga 2 units para di mahrapan ung isa. so tankless sya just like the regular single shower heaters. well may tank pero maliit lng sa loob. pwede rin dun dumaan sink lines.

nasa 10k ata un..

cons ng centralize:

1. kahit walang gumagamit ng hot water nag-On yun mag-isa so magastos sa kuryente. may heat losses kasi kahit gaano ang kapal ng insulation ng tank kaya On-Off operation nya.
2. may delay ang dating ng hot water. naka-open na matagl yung faucet/shower mo hindi pa mainit yung tubig so medyo magastos sa water kung aantayin mo uminit ang water.
3. pag may nag-open ng isa pang outlet bigla na lang lalamig yung shower/faucet na naka-open. like say naliligo ka tapos may nag-open sa kitchen, whew, cold water agad yan.
4. hindi continous ang dating ng hot water. ang design kasi nyan pinapainit nya yung water sa tank. so pag may gumamit ng hot water progressively lalamig yung water sa tank as the hot water is used. kung malaki yung tank hindi mo siguro mapapansin, pero pag maliit ang tank or madami gumagamit pansin mo agad yan, panay adjust mo sa hot-cold faucet para makuha mo yung desired temperature mo.
5. pag malapit yung faucet/shower sa tank may tendency na maka-burn. minsan kasi open mo muna yung hot, tapos meron pala kakatapos lang gumamit so very hot water yung nasa pipe at lalabas agad yun. imagine mo nakatapat ka sa shower tapos bigla lalabas 60 degree C water. araaaay!

better yung individual pards. lahat ng 1,2,3,4,5 na yan sa taas wala dun sa individual heaters. medyo mahal innitial investment pero sulit naman. sa bahay namin individual, medyo halo-halo lang nga yung brands at nabili ko kung ano yung naka-sale ehehehe!

mas ok na yun individual heatr for each bathroom, mahal sa kuryente pag centralize but its more convenient like, im picturing it as my uncles home in california, where they have centralize heater for all water supply, tapos yung faucet nila can be hot or cold

[shadow]

thank you sa mga nag reply.... buti na lang meron tsikot, paniwalang paniawala na ako sa salesman doon sa MC eh....

in the long run, individual water heaters are cheaper than centralized water heater. Why? A centralized water heater must get the hot water from the central boiler to the shower and a lot of energy and water is wasted along the way.

my home has individualized water heaters for each bathroom... and a hot/cold water mixing faucets so you can get the water temp just right.

for individual shower heater, maganda yung JOVEN 2000E, maliit lang, cheaper (~P4k)than other brands (~P5k), electronic continuously variable temperature control (triac control), and a pressure switch that turns on/off heater power whenever shower faucet is opened/closed ... it comes with a valve for the inlet to let you adjust shower flow in cases of high-water pressure (the shower faucet will only serve as on/off instead of a flow regulator) ... it has a neon lamp to let you know that power is applied to the heater and its brightness is proportional to set temperature

yes it is more economical to use individual shower heaters ... and for even more savings, use them at lowest flow and lowest temperature settings just enough for a convenient shower bath.

trivia ... although normal body temperature is 37C, a shower (or ambient air) at 30C is already "too warm" for comfort ... shower at 26-27C is the comfort zone for pinoys like me

yes, mas economical in the long run ang individual heaters. and kapag nasira, isa lang ang mawawalan ng hot water, unlike sa centralized, kung nasira, lahat walang hot water.

ang advantage ng centralized is kahit brownout, meron ka pa rin hot water within 24hrs, basta't hindi malakas ang gamit, yung panligo lang.

also, kung talagang malakas kang gumamit ng hot water, like pati sa laundry mo e gumagamit ka ng hot water, and sa paghugas lang ng kamay nagmimix ka rin ng hot water, maaaring mas maging economical ang centralized heater. 3000W ang max electric consumption nito as compared to individual heaters na 6000W.

bakit di ka mag solar heater? it will pay for itself in the long run.mag tanung ka din ive been using it since 2000.

[Doc Diesel]

we have one in our home in pque. electric bills were a bit higher. maganda lang eh you can have heated water anytime even for cooking. our heater has this thermostat installed wherein a certain temp. is set. it only turns on when that temp. is not reached.

[chieffy]

tulad ng sabi nila malakas nga sa kuryente centralized heater...noong una akala namin dahil sa paggamit ng aircon pero di bumaba ang electric bill sa pagtigil ng paggamit ng aircon...nakatipid kami sa apartment ng kuryente noong bumalik kami sa pag iinit ng tubig sa takure...bumababa ang kuryente from 5k to 2.5k nang itigil namin paggamit ng centralized heater...

yup.. solar heater nalang.. kami din.. tagal na solar heater namin.. 1998 pa yata or 99.. pag walang araw.. automatic.. turn sya electric heater... so far ndi naman kami nagkakaproblema... hehehe medyo mahal lang nga initial cost...

solarhart yung pinakanauna and sikat eh.. but saamin solaredward...

but ngayon madami na china brands eh.. panget lang nga hitsura.. but.. so cheap yung mga chinas... ndi ko lang alam kung tatagal.. hehe

one downside with a solar heater. You need to clean it often since the air in the city is relatively dirty.

[AC]

yup.. wipe lang ng maid glass ng solar... mga once a week.. mabilis lang.. takes only like 2min.. at most na 5min

pano kaya yung mga nakalagay sa taas ng roof? dami ko pa naman nakikitang solarhart na nasa taas ng bubong, hirap sigurong linisin yun.

[wildthing]

mahirap lang naman kung 45 degrees and angle of elevation ng roof...

yup I think solar heated water tank would be a good option for you. 24 hrs heating and cheaper electricity cost. Minimal na downside yung problem sa dumi IMO...try applying rainx dun...e di iwas watermarks na....

next best would be the individual water heaters...I also have come across an individual water heater na capable to service 2 water lines...kung merun kang bathrooms na almost adjacent lang, you can buy this instead (tagusan lang sa pader and water line)...lalo na kung shower line lang naman ang gusto mong painitin.

[BlueBimmer]

if u opt for individual shower heaters make sure to get the newer models with ELB (Earth Link Breaker), this feature will detect if there's a ground and immediately shut off the heater..although on some of our old shower heaters wla naman prob even without this feature but its better to have it nalang. avoid old models without ELB.
