Gas water heater

No, that is something you add and as far as I'm concerned, a good addition. At least the float system to refill the tank. I have mine set to when tank is 1/3 empty to refill. I decided I didn't need the pressure pump since my tank is so high and I get great pressure without it. When there is a power outage I know I have plenty of water at my disposal until power comes back on. I see all this new construction outside my perimeter wall of my complex where they are just putting in submerged pumps and every time the power goes out, they have no water. Then, they add gensets. I think the tank system investment would have been cheaper then a genset and then the gas to run it when needed.

Don't they also need the genset for TV, a/c, etc?

Sometimes the need to put in submerged tanks is for space and/or aesthetics. Too may nice villas look ridiculous because they add a concrete water tower or place a tank in full view. It's the same with A/C outdoor units...as soon as I bought our place I had the contractor move all the A/C compressors out of view, and covered from the sun's rays.

Not as bad as they would need water. Don't you think?

Well it depends, some places people live without electricity for a few hours, but some places the a/c runs 24/7. If you live in an a/c on 24/7 house, then you are going to be running the genset so it's irrelevant.

Except with the pump's wattage demands you will probably need a bigger genset.

watt?

A submersible pump is around 250W

http://www.shimizu.co.id/products/sp-310-bit

A regular pump around 125W

http://www.shimizu.co.id/products/PS-135-BIT

A genset in such a house I guess is 5000W or more.

To get the water out of a well using a 125W pump will leave you waiting a long time. An in line pressure pump might be as low as 125W but jetpumps for wells can be closer to 1,000W. Submersible sounds nice until you have to pull everything out of your well to service it. Fast, cheap, and it looks good will only come back and bite you in the ass here.

My well jet-pump uses 250W continuous....http://tokopompaonline.com/pompa-shimizu/pompa-jetpump-shimizu-pc-260-bit/

The well is 30 metres below ground and the tank is on the roof of a 2 story house...worked well for 5 years but needed to empty the tank of silt recently.

I don't use the bladder accumulator tank as I've a 125W pressure pump for the gravity/pressure side to the faucets... so the bladder tank is used on that pump.

So we fitted a Paloma 5l gas water heater. These gas water heaters are rated for minimum 0.2bar pressure.

I'm not sure what pressure we had, but it wasn't good. Maybe our tank was 3m high?

Anyway, the gas water heater worked kinda, but you needed to have it set so the temperature of the output was the temperature you wanted to use. If you mixed it with cold water, the pressure would drop to low and the gas went out. The heater is on the outside wall.

So we now fitted a new tank @ 28m head (net maybe 18m), and there are no problems and it's great.

One thing that is maybe slightly diverting is the question of ignition. The 5 litre models use D batteries, the larger ones mains electricity. Some of the larger models may also preheat the water in the pipes using electricity.

This is what I said in post 4. It is obvious if you open cold water the water pressure for hot water will decrease, wait till you are doing laundry with washing machine, driver is washing car, wife is washing dishes at the same time...... the water pressure will drop significantly. Glad you resolved the problem by raising the water tank.

i also use a gas water heater in my house. it's cheaper and more effective than the electricity one. (i use the electric water heater in the apartment, the problem is gas water heater consume space bigger )

Gas just makes more sense. 1kg LPG = 13.6 kWh, so it's half the price of electricity and doesn't cause the shitty electricity network to meltdown or cost millions in genset & other costs.

You may not seen them in Indonesia because ... it would be more dangerous to use them. Not only you have to worry about gas leaks but also fumes going out from burning gas CO2 and the deadly CO (working chimney/ventilation shaft is a must). How many houses do have those chimneys or ventilation shafts, who and how is checking if they are working?

Please remember you have to provide min water pressure if you use boiler. If your water pressure sucks (remember you want 30 ltr/min) and it does in many urban areas in Indonesia then it would be not appropriate to have boiler heater (damaging boiler). They also consume/burn a lot of gas. The more powerful boiler the more gas they burn. It is not about end bill each month but a bit of "inconvenience" of getting new gas tanks every few days. At least this is how I see it.

My options would go to:

1. Electrically heated water in a tank isolated with mineral wool.
2. Using ordinary kompor for cooking to heat a bucket of hot water heater brands list and then while taking shower mixing cold and hot water with gayung.
3. Solar heated water on the roof.

Hello. I’m a home owner who buys rheem electric water heaters for the past 15 years and they don’t last. Recently after 5 years. They leak from the sides. Most of my installations use city water. What water heater brand do you recommend? I’m looking for reliable electric water heater. Tankless water heater is not an option for me due to the setup. Thanks

How about a Dutch brand, like https://images.app.goo.gl/nYVKQSFg374yhK5WA

If the bathroom is vented, ie. ventilation blocks or slated windows then modern gas heaters don't require chimneys. The exhaust, if we call it that, is not even hot enough to blacken the ceiling.
That being said if I were to add one to my house , yes, I would probably stick it on the outside of the bathroom wall to save knocking an extra hole for the gas pipe.
