Hi, if currently i install storage water heater and later in 5 years i want to change to solar water heater, do i need to redo the piping? can i reuse piping from storage heater?

safer get 300L, many solar claim better heating, temperature upto 90 degree bla bla bla, tested in bathroom it is impossible to get 90. So, they will say, no no cant measure in bathroom, we nd to measure directly in the solar, ok fine, but cant be solar 90 degree but comes down to bathroom only get 60 degree or 70 degree.

So, if a solar company claims they can do 90 degree celcius, hence u use less hot water, so u no need a big tank, ask them pls write black and white on the receipt, if cant achieve 90 degree demand full refund

To share, i used both evaquated tubes and flat panel, both +- max heat, dont feel a big difference. What i can honestly tell u and accurately inform is that my flat panel aquasolar can achieve a max of 68 degree celcius, measure in my top floor bathroom (max hot) 68 degree is already smoking hot, if really a solar can go upto 90 degree in bathroom, u might accidentally get scalding, imagine pouring boiling water on yourself

Comfortable shower temperature ard 38 - 42 degree +- so with 68degree, mix cold water, u get a nice shower
Bigger Better as u STORE more HOT WATER, in case rainy season.

if u have several storage heaters connected to several bathrooms then u need to join all the hot water pipes before connecting to the solar.

if u have only 1 big storage tank located at the top floor then can jus change to solar without any modifications

I always like the water pressure from rain wash of the hotels. It’s a double storey house with 3 bathroom (2 upstairs 1 downstairs). How much is a healthy budget should I prepare for a decent one?

It doesn’t come with hot and cold pipe unfortunately... only 1 for the rain shower and 1 for instant hot water.

estimated plumbing cost
hacking and install hot water piping @ rm 900 per bathroo

estimated rain shower n mixer cost rm 400 - 800+-

Solar system depending brand average ard rm 4k

I see, I'm keen on this! How does the Aqua Solar L66 performs and what are its competitors in terms of price/performance and more importantly the after sales? Developer provided water pump, I haven't exactly turned it on cause waiting to install my outdoor filter before letting the water up. Do I need additional pump for the solar heater itself?

How it looked like, well its a photo from a drone... (got some defects on the roof).


Side note, got any recommended contacts for plumbers in Melaka?

Wonder any chance to repair when the solar panel (copper pipe inside?) leaking?
