So you're thinking of installing one of the larger 20 or 26
continuous flow hot water systems at your place
Now it's important that you set it up correctly
so you can use it to its maximum potential
In this video we'll show you how it's done
and tell you about some of the future benefits
that you'll receive
G'day, I'm Ben from Beautiful Plumbing
Before you watch this video
it's important that you watch a video
entitled "How to Choose the Correct Size of
Your Continuous Flow Hot Water System"
Now if you've already watched it, good
so let's get stuck into it
First of all, you need to make sure
that you can get a water supply
to your hot water system
that is not the usual 15 mil but the 20 mil
You can see the difference
Better flow
And also out of the hot water system
you need a hot main this larger pipe also
All right now I'll try and explain about the manifold system
I'll tell you the truth
Probably easier if I draw it for you
So you have an existing house
or building a new house
and have made the decision to install
a 20 or 26 continuous flow hot water system
I'm guessing you'll need to supply hot water
to your kitchen, laundry, main bathroom
and of course your ensuite
Now your gas continuous flow hot water system
will need to have a larger 20 mil diameter
water pipes supplying it
so it makes sense that you'll also need
a larger diameter pipe
exiting your hot water system
to pipe the hot water to all the fixtures
Your plumber will usually run a larger hot main
throughout your whole house
then branch off in smaller pipes
to feed your kitchen, laundry,
main bathroom, and your ensuite
which will work great and ensure minimal pressure loss
when two taps are used at the same time
except there's one big problem
Just say you wanted to wash your face with hot water
you would have to flush out the cool water
from the entire large hot main
before any lovely warm water touches your face
Wouldn't it be better if you only had to flush out
the cold water from the smaller diameter pipe?
Yes, but then they would have some pressure loss
when using two taps at the same time
Here's a solution
Still have a larger diameter pipe
coming out of your hot water system
but keep it as short as possible
and then run smaller diameter pipe
individually to each area
Now you will enjoy great water pressure
and will be only flushing out a small amount
of cooled water
before the tap will run nice and warm
So now we'll show you
how we retrofitted a 26 continuous flow hot water system
to these three bathrooms
in this beautiful Italian mansion
I mean check out those pillars and arches
Just gorgeous
So this is the hot water system they have at the moment
It's a 170 litre highly inefficient gas storage
Check this out
They obviously had a Temp Valve installed before
but they got rid of that
cos I suppose they weren't too concerned
about having scolding hot water
So I suppose the original plumber was told to
put in the biggest hot water system possible
and never gave the owners
the option of maybe putting in a continuous flow hot water system
and it would have been so easy
because the gas meter is just
on the other side of this fence
So this entire mansion has a 15 mil diameter hot main
going throughout the whole mansion
going to all the bathrooms
so would have been fine to put in, say,
a little 16 in this situation
but you would have caught a little bit of a pressure loss
when two taps are turned on at the same time
So we installed a 26 continuous flow hot water system
at this owner's last house and they loved it
so they've asked us back to the install a 26 here
retrofitted, installing new manifold
and also some temperature controllers
so they can use the hot water system to its full potential
First of all we need to test the gas main
then we need to disconnect the old hot water system
trying to find the 20 mm cold main underneath
so we can run up the 20 mil main
straight up into the inlet
Then we need to supply a new 20 mil gas main
just cut under here under the meter
go through the wall and then have a direct line
straight up to supply to the new hot water system
Next we just need to pull up this paving here
and find where the hot water main
going through the bathroom
the bathroom upstairs, the laundry
and around to the kitchen
and then we can install a manifold system
and then run separate lines to each one of these bathrooms,
laundry, and kitchen
So now we've found each individual main
that goes into the house from the kitchen, the laundry,
each one of the bathrooms
and then we've run separate individual mains
all the way up to the new hot water system
As you can see we've run a new gas and water mains
both the large size up to the new hot water system
Now why we installed it so high
because there's an aircon unit going underneath it
So here is a manifold
As you can see all the separate lines from the bathroom,
and the laundry, and the kitchen
all run off this larger pipe here
Now this is a fantastic set up
to minimize the pressure drop
So yeah you'll be able to run two showers
at the same time with this set up
So now the only thing left to do
is set up the transmitter
and get these wireless controllers connected
and she'll be up and running
but we'll do that on another video
You can check that out on our website
So if you're building a new house
or thinking of retrofitting your existing house
with a continuous flow hot water system
with a manifold system
and you live in or near the Shire of Kalamunda
give us a call
We'll be happy to help
