HOTWAT SYSTEM
HOTWAT system provides instant hot water by single
pipe hot water temperature maintenance. HOTWAT systems
are available for installation in all buildings
provided with hot water
services - from private dwelling houses, sheltered
housing, offices, apartment blocks,
commercial buildings, government centres, hotels
and hospitals. |

The
Problem: Modern living dictates that buildings
shall have hot water available whenever and wherever
needed – and preferably instantaneously. Hot
water is normally provided by a boiler in a centralised
or localised heating system
After draw off of hot water at a supply point, the
pipe feeding that supply point remains full of hot
water which, under static conditions, cools to ambient
conditions.
When demand resumes, there is a delay period whilst
the now cold water is replaced by water heated from
the boiler. The delay is both frustrating and costly,
as the volume of the static head of water must effectively
be heated each time a tap or valve is opened.
Virtual instant hot water at taps was provided by
a twin flow and return re-circulation system. The
length of dead-legs was minimised so that hot water
flowed soon after opening the tap, and so wastage
was reduced.

HOTWAT
Instant hot water by single pipe hot water
temperature maintenance. |
|
| This system has numerous shortcomings:
|
- the flow/return re-circulating pipework and
thermal insulation has twice the capital and
insulation costs compared with a single pipe
system.
- heat losses from the flow/return re-circulation
system are twice those of a single pipe system.
- maintenance costs are incurred with the introduction
of pumps and other items having moving parts.
- dual pipe systems require twice the space.
- the system must be balanced.
|
The Solution: The
HOTWAT single pipe temperature maintenance system
overcomes ALL of the shortcomings of the re-circulation
system.
The HOTWAT self-regulating heating cable is fitted
to a single hot water supply pipe to maintain the
hot water temperature by compensating for heat losses
under no-flow conditions. Compared with a re-circulation
system, this results in:
|
- Reduced Capital Costs
- Reduced Operating Costs
|
Greater system flexibility is provided by the addition of variable system temperature settings. Where required, different parts of the building can be programmed to maintain different temperatures. Control is provided by a technique known as Powertrimming.
The HOTWAT system can also be provided with D-BUG, a pasteurisation process whereby the static pipework system is periodically raised in temperature to disinfect the system.
