PV solar only generates electricity, so for hot water u will need to buy storage heaters. if 1 - 2 bathroom & low usage of water water, storage will be better but if more bathrooms then solar better.
1) 1 bathroom one storage heater, so if u have many rooms then cost of installation not cheap
2) If storage heater spoils or leaks, to replace not easy and may damage your plaster ceiling
3) if you did not boil the water after showering, then the next time u shower, need to wait 30 min to boil. Solar is automatic, daily heat up by the sun
Thanks. So weighing cost wise:
1) Solar heater would be good option, free heating power except rainmy day need to run electricity to heat up large storage tank. Initial cost ard rm6-7k, plus installation cost of concealed stainless steel pipes from rooftop to 3 bathrooms.
2) storage heater would be lower upfront cost, as 30L/50L cost less than rm1k each nowadays. Installation cost for more units but offset by shorter distance to lay concealed stainless steel
pipes. Future maintenance not a problem as i am inclining to get get ACP ceiling instead of plaster for bathrooms. Long run electricity consumption cost savings could go for Solaris but then no guarantee no guarantee on the scheme lifetine and rebate structure.
Dilemma......
