A note to the OP. Take no heed of all this pontificator about pumping water. Whichever shower heater you find with an internal booster pump will work just fine.

A lot of you guys are not thinking this through or maybe not thinking just reacting. May I explain for the technically challenged???? Many houses in Thailand have shower heaters. If you turn off the water supply to the house and open the valve to the shower heater it will not switch on. Why? The shower heater requires positive pressure in the supply line before it switches on. If the shower heater in question has a booster pump to give an adequate flow at the shower head, it still requires a positive pressure at the inlet before it will switch on.. Thus the pressure in the line supplying the shower heater must always be positive, about 1 psi. There is no suction taking place so there will be no potential for ingress of germs into the supply pipe.

No. Not if the potential water supply to the shower heater is greater than the shower head flow. A 1" pipe under gravity will supply 16 gpm (3/4 pipe 11 gpm) and the shower unit requires a minimum of 1 psi of positive pressure to operate.

You are thinking too much????

Remember the sign in that Soi Soweto bar???? "We do not serve Africa Man" A man of unknown nationality a Mr. Ramjam Full reputedly had his gold chain stolen on Beach Road in Pattaya. (EDIT:) Added after Nigelforbes reacted

I believe it is just another name for a (Panasonic) Jet Pump. Which may not actually be a Jet Pump. Just called that. A shower heater only provides about 6l a minute. I hardly think that will produce any negative pressure in, say, a 1" supply pipe running at the minimum 1 PSI.

I think there are very few. I have a Panasonic DH-3NDP1MS unit bought in from Malaysia which works well. I think on Lazada there is only one.

Democracy only works if the losers accept they have lost.

Well you know the answer then.???? ✈️

^ They are all 565. Cost difference is likely tube size and whether it is here or from overseas. Seems 600B -ish for 50ml for local suppliers???? There is one at 134Baht from Chiang Mai might be worth a punt.

600 baht a day is 13,200 a month for a 5-day week. Maybe the push back is coming from sweat shops that work 6 or 6 1/2 days a week???? Like the Tesco jeans place in Mae Sot.

I'm not a manufacturer of cable. It depends a lot on the construction and materials of the cable. Japanese info ranges from 7A to 15A depending on cable construction. Then there is usage. Unless you intend to plug in your shower heater, most domestic users will be less than, say, 1500W. So nearer to the 7A end of the scale.

Why? Would you expect a Chinese clinical psychologist to speak English.

..and you might notice here then,???? that 7-Elevens at petrol stations don't sell alcohol.

No news of the Bukkake Bank then????

Is cheating corruption???? Maybe just doing what is needed to get a better salary. What some consider cheating, others may call using the system.
