Hot Water Tank

[regedit]

Looking to have one fitted in a 2 storey house to serve kitchen, upstairs bathroom and downstairs bathroom. Need to add all the hot water piping. Need to decide where to locate to run electric supply. Does it make any difference if the HW tank is located at ground level or upper level ? I guess should be close to main point of use? Thanks.

Yes, put it near to the biggest user (shower?) so you don't waste hot water waiting for it to arrive at the tap.

Assuming the tank is rated for the pressure of your pump it can go up or down stairs.

in the flood repair, just realised that my hot water pipes were not thermal sealed. I lost kW of energy through the wall.

make it as an explicit requirement to the installation guys, especially if you have long service points.

Or a possible consideration that goes against that a little bit, is although the showers use the most water, by far, most folks tend to have 2 a day, but how many times do you want some warm water in the sink, particularly if you don't have a dish washer and have a secret desire compete with my in laws for growing bacteria !!!!, hence regularly rinsing & washing is the order of the day?

What I am getting at is the wait for the heated water to come to many little uses.

Have just put a multi point for the kitchen thus instant hot water, hot water tank for bathrooms so therefore in really hot periods can turn the temp down and doesn't affect Kitchen hot water.

my hot water pipes were not thermal sealed.

Good tip. How do they do that exactly ? I've only seen the metal connectors which have some kind of locking/sealing mechanism.

mine is a bare copper pipe and fixed below the flooring, and no isolation on the pipe. water from the heater is about 50-60-deg C and the floor is about 30-deg C, can imagine this is exactually the floor heater in principle.

if I could do it again, plan the pipe over the ceiling ( check water presssure first ) and free it from any contact point ( free from thermal transfer ). seal the pipe with thermal tape.

AC pipe insulation works great

piping over ceiling, not in floor

wrap insulation in chicken net when installed in walls as "rebars" for plastering

and water leaving tank should be at least 80C

did anyone mention a hotwatertank should have a one way valve on out pipe, to avoid draining tank and thus burning heater if a tap is left open and no water supply

I am clearly missing something with the comment above, can you please explain?
