Need Help! How Big A Storage Heater Do I Need?

[Chivalry 0]

Hello all!

I'm at a loss right now, and hope all out there can share your experience please.

I have two toilets, and in one of them I'm installing a 1.8m bath. I also run hot water piping to all the sinks, bathrooms' and kitchen's.

Question 1: How much storage should I get? I'm currently looking at a 68L Joven heater. Is that enough? Should I get a 91L instead or would that be an overkill?

Question 2: Should I install 1 or 2 storage heater? Will I suffer from a substantially lowered pressure if both bathrooms shower at the same time? If I get 2 (1 to master bathroom, 1 to common bathroom and kitchen), what kind of capacity combo should I be looking at?

Thank you!

Dear Chivalry,

If yours is a new house under construction, then the questions are best for the architect to deal with.

If yours is an existing house/flat, then very often the question of storage capacity is secondary to whether:

- how the hot water piping could be installed (look out for the beams & columns),

- how much space there is above the false ceiling to house the storage heater, how to divert the water from the main in, how to run the power to that area, if the ceiling opening to access the storage heater would get in the way of any lighting, where the on-off switch(es) could be placed etc.

Start with a plumbe?

Just my two-cents worth.

Cheers!

Hi there

Thanks for the reply. It's a resale HDB EA and I'm currently doing the renovation now. Piping and wiring wise no problem, so renovation contractor told me it's a matter of choice to go with one or two water heater.

One bath tub supplier told me having one or two heaters will not affect the water pressure at all, or the water pressure loss of having only one storage heater is so small that you won't feel the difference. Another supplier told me to get two heater (2x heater = 2x installation costs + 2x wiring cost for bath tub switch + slightly more costs in terms of piping)

So.. hehe.. I still blur..

1) one or two bath tub?

2) How big capacity should I get to service two bathrooms (one with bath tub)...

Any light to be shed on this would be deeply appreciated!

Thank you! =)
