don't mind me asking GibsonBFG - which shop is selling hitachi/panasonic water pump below RM500? went to HLK and they quoted Hitachi WM-P180GX for RM650 (exclude installation)

CH2-50PC is sufficient for 4-5 bathrooms. You cant hear the pump's sound but you might hear the vibration noise. If ur ceiling is high and the base for the pump is solid, you could hardly hear the vibration.

What is a reliable water heater brand/model? Has anybody had bad experiences with cheap Chinese products?

if i were to use a water pump, would my electricity usage increase for my standard water heater because i will have to increase the temperature to the highest to make the water hot due to the pressure of the water is high? pls explain coz quite blur on this.

currently my house with no pump n the water heater temp is onli half way so consumption is based on this but pressure not so canggih

You need to increase the heat if your water flow/pressure increase. The water cannot get enough hot when it flow fast from point a to point b inside the heating element

Of course your bill will increase too.

if install a water pump + using instant water heater w/o pump will the water get enough hot?

Depend on your instant heater wattage. Normally 3.2kw is enough hot.

CH2-50PC is sufficient upto 5 bathrooms. Grundfos pumps are silent, whether u can hear the noise or not depends on how u install it and also the structure of ur house. You definitely wanna get an anti-vibration pad to reduce the vibration noise.
