Use the instant water heaters. There are even good local brands - for eg I have used Joven for more than 10 years with no complaints. I am not advertising for Joven - it is just that I have not tried other Malaysian designs.

I don't recommend the separate water heaters unless you have a passion for hot baths or jacuzzis. These water heaters are greedy for electricity.

I have no experience with solar-heaters but in the past they produce trickles of water. Current technology have probably overcome that defect. But beware of those that have electrical heaters as backups - this means the designers are not confident of the performance of their own designs.

If you can afford it, get a water pump for the upper floor water network. That is because the gravitational feed to the taps in the upper floor is very weak due to the short difference in height from the water tank. Ask your plumber on this - I don't think a DIY can handle this easily.

If you don't want the complications regarding a water pump, just get instant shower heaters that come with a built-in pump. These pumps are small but sufficient to give some sting to the showers.

using one of those named "alpha", not the cheapest, not the highest price.
pump is sufficient and heater i can use max. 25% in order not to suffer any burns :D

Electric storage water heater is the type which has a tank to hold the water while it gets heated. This is the type which I feel is heavy on the electric bills.

Joven and Alpha are Malaysian instant water heaters - there is no storage as the water is heated while it flows to the shower head. I believe this is more economical and practical if all you need is a hot water shower.

Grundfos seems to be the de facto household water pump. I have used one which supports 2 bathrooms for almost 2 years and have no complaints except for some pump noise when it is operating.

sorry guys,

you are talking about those lebih-kurang little pumps in the main supply to get better water pressure, aren't you??

i was informed by a neighbourhood friend that those pumps are "illegal" as you suck the little pressure of the syabas pipes and dry up the following houses even more.
is that information correct ??
coz i wanted to get one of those pumps but cancelled this plan allready :confused:

Sorry expat - you did not read my contribution earlier on. I am talking of installing a pump for the upper floor plumbing - ie between the water storage tank and the faucets in your bathrooms on the upper floor. Nothing about pumps attached to the mains.

while we are on the subject of pumps and heaters - has anyone used a water pump to increase output from the solar heater? I was told by a shop that it can be done, but i am sceptical. Was looking at my heater and it appears that the water output is dependant on a small holding tank being filled with cold water - this flows into the bottom of the heater and allows hot water to flow out the top. My concern is that the pump would suck water out faster than the holding tank can fill - then the flow would dry up!

I am interested in enquiring about instant water heaters, the pressure in my bathroom is rubbish, and I would like to change my shower unit, whats the best brand of instand shower unit to use, and would I have to put a pump in to increase or cope with the pressure, that the water flow is good or even reasonable?

How easy is it to do this, does this involve great renovation in the bathroom?
