water heat

[Jordan]

My bathroom is so far away from the water heater, it takes ages to get
hot water there. Is there an electric heater that can be fitted near the
tap to quickly heat up the initial flow, then turn itself off when it
senses the incoming water temperature is high enough?

This is what you want:

Thanks for that.
Interesting, but I'm not sure it's really what I want, because there
still wouldn't be any hot water available for some time. In my case it's
about 30 seconds in this weather. It'd be good for saving water though.

I'd prefer the "luxury" of instant hot water. A separate, automatic
switching heater, rather than a pump, could provide this. I don't think
the extra power needed for short term heating would be excessive.

I wonder if anyone sells these?

yeah, any of those on-demand heaters would do the trick, they all have
thermostats.

you may need to have the house supply upgraded to 2 phase though.

1) you could try lagging all the pipework from the heater tothe taps.
2) ou could install a HW recticulation system that pumps HW through a
loop to warm up the pipes before openig the taps.

Maybe the hot water unit for a shower - it probably has its own built in
thermostat if the water exceeds a certain temperature.

I know someone who had this problem in their kitchen. They installed a
small electric hot water on demand unit under the sink, fed from the
main HW system. Worked just fine.

These guys have one:

http://www.stiebel.com.au/water-heating/products/dhc-instantaneous-single-phase-water-hea/

Several power ranges: 2.4kW to 9.6kW, the higher wattage units would
probably require upgrading the mains wiring.

It's meant to be fed with cold water so you'd have to check if it stops
heating once the incoming water warmed up, or conversely if it has a
limit to the output temperature (which is quite likely in these days of
safety consciousness).

As a guess, his curren tank is off peak and the heater would have to be
on standard power. Might just need an extra circuit solely for the
instant heater.

** Tough.

** Nope.

The electrical power requirements for such a heater ( about 6 kW ) is
prohibitive, not to mention the high cost.

Could be.

Could be. Main heater is gas instantaneous.

1) It'd still be very cold a lot of the time, so delay will still happen
even if lagged. Pipes are plastic.

2) That sounds wasteful. I think it's what they have in hospitals etc.

Worth checking, thanks.

specific heat of water

times

flow rate

times

temperature difference needed to be heated


you can look the fist value up, the other two will need to be measured

** Go get fucked you pig ignorant wog cunt.


FYI and others:

The once popular " instantaneous " type electric water heaters ran on
three phase power and consumed over 10kW.

They were good for one shower head at a time.

They were banned from domestic installation decades ago by state energy
authorities.


BTW:

The OP is a fucking nut case moron.

** That is a very neat idea !!

The low capacity unit supplies hot water for only a few minutes, then when
it would otherwise run cold - it simply does not as the in-coming water is
already H O T hot !!

A plug-in, 2kW rated, 10 litre unit would be fine.

I wonder if it is 100% legal under plumbing rules......

I'd sugest the "lagging" trick first.
clack rubber has tubes you can split and cable tie around the pipes to
slow down the thermal loss.
