Dear Sifus, im having a mini dilemma here. What I intend to do is to have a medium sized (10"-12") rain shower connected to my soon to purchase water heater                                            
                                            
My current method is to purchase a water heater with pump and rain shower, and purchase a new shower head seperately to fit to replace the default shower head (as the one provided with the heater is small)                                            
Approximate cost would be                                            
Water heater with rain shower- RM700-RM800
10-12" Shower head - RM300-RM400                                            


The heater model im planning to get (joven i70p)
                                       
Question 1                                            
My question is, do I have any alternative way to get a rain shower setup with my heater since from what I checked                                            
the rain shower column itself can cost between RM500-RM1000                                            
                                            
Question 2                                            
Will my water heater with pump be able to produce enough presure to push the water up to the rain shower?                                            
Current built in shower head has decent water pressure. (any idea how I can quickly check the pressure readings?)                                            
                                            
Question (slightly off topic)
Why is the water pressure in my 2nd bathroom stronger than the one in the master bedroom?

Question 4
Are the shower head fittings standard?

Thanks in advance!

Thanks Lee for the detailed reply!

Regarding the centralized heater, i dont think thats an option for now due to budget constraints and that im currently living in a two bathroom condo with only two occupants. Might consider in the future though. Will the centralized system come with a dedicated water pump?

Was a bit sceptical on the ability of the heater to cope with a different shower head and theres no way for me to 'tryand error' in this case. I guess better not take the risk

Is there a quick way for me to detect the current water pressure by DIY?

Thanks for the reply kimsim. Took a look at rinnai website, is this the one u meant?



Tried looking for the spec details of the shower head but couldnt find any on the website. Any suggestions on where to get the unit?seldom see rinnai heaters so far in kl

Looks like ill have to settle for the default rain showers from heaters for now. Ill go for the biggest one i guess..
Rinnai looks good

Oh and thanks for sharing ur bathroom setup! Looks great with the centralized water system u have there. I could only dream of having that for now.hehe.

Went to senq a few days back and all they had were the alpha rain shower series which were the weird bended small rain shower. Didnt really like it. I think ill try to take a look at another outlet.

I was initially planning to get a setup like yours the 'budget' way but i guess you get what you pay for applies well here..

Thought of getting any instant heaters with rain shower and refitting the head with something like this for an additional rm400.is it advisable?So heater plus shower combo might cost me around 1000-1200. With that budget i guess that might be the best choice i have. For the centralized system i might consider it 4-5 years down the road when i renovate my bathroom.

thanks for the input guys

i guess having a 10-12" rain shower is out of the question for now due to budget constraints as well as risk from issues related to water pressure. Maybe i will reconsider when i intend to renovate my bathroom.

Currently im stuck between the two choices below which is the same price

Not sure which one has the bigger shower head and if theres any difference feature wise. i know that the i70p has an on off button for the pump. unsure about the rinnai one though

Hi there ozak,

I bought my unit also yesterday and wikl be installing today.
You mind sharing how much you bought it for?
Got it at rm750 without installation from a bath and kitchen shop in shah alam.
Agree with you,Really tired looking around for this particular model

Wow u got it cheap!!where did u buy it from?i have yet to find a decent shop to regularly get my stuffs from.

By the way, i noticed that even at the highest setting the water is not even close to scalding hot, i mean i dont intend to scald myself, but it is only warm at most even at the highest setting, even worse when using the rain shower mode. Is it considered normal? Or is my water pressure too strong?

Seems like the heater runs fine even with the pump turned off as my water pressure is considered quite high even on normal days. Should i regret buying a pump unit?hehe

I too am uncomfortable with the wiring setup done by my installer, worse is he charged me rm100 for installation..
Will consider using the silicone gel like u did with yours

I remembered the heater in my parents home were the type that hurts you if you set it too high, but then again the water pressure there was quite bad due to it being an old apartment.

Tried playing around with the settings today, guess i cant get both high water pressure and high temperature at the same time on a budget.

Seems like the best result is with halfway open valve and with pump turned off. Rain shower mode with pump on, the water is just slightly warm at best. A bit disappointed.
