- Water tight control box in impact resistant plastic - can be
located for safe convenient operation up to 30 metres away from
- With the exception of the drawing off of the hot water for the
washing operation, all other operations, including filling,
heating, temperature control, prevention of cold water backfill
during hot water draw off and dual wash operations, are totally
- These heaters offer automatic filling, temperature control and
prevention of cold water contamination during hot water draw off.
Drawing off the hot water and switching the elements are manual
operations. (The element may be left on continuously as the
thermostat will maintain the set temperature without overheating).
Manual - Water
temperature is automatically controlled by the thermostat, all
other operations need to be performed manually.
Single and three
phase power -
Standard 240v single phase power
supply is sufficient to operate 3kW and 4kW elements (up to and
including 225 litre models).
6kW, 9kW and 12kW elements (295 litre
models and larger) require 400v 3-phase power supply
For exceptional circumstances a 6kW
240v single phase element is available, on request.
3kW elements are also available in
3-phase- 380v for export requirements.
Copper / Aluzinc - Loheat's
tough 20 gauge roll top copper cylinder and aluzinc outer casing are ideal for most water conditions.
Aluzinc is tough and highly corrosion resistant , and gives the
look of stainless steel.
Stainless steel - Stainless
steel water heaters are recommended in areas of highly acidic
water, where corrosion of the copper cylinder can occur, or in
very hard water areas where frequent descaling may cause damage to
copper cylinders. Stainless steel cylinders and tanks are
manufactured in 316 grade stainless steel, and have proved to
offer exceptional resistance in acidic and hard water areas.
In hard water areas it is strongly
recommended that a water conditioner / water strainer be installed
alongside the water heater. We offer two systems for scale control
which can be seen here.

Dual Wash - This is a standard
feature on Loheat Dairy Water Heaters of 160 litres and larger.
Simply heat the full capacity of the water heater during the off
peak period (typically midnight to 7am) and use half for morning
cleaning and half for the evening cleaning and then refill. The
total capacity of the heater must be sufficient to supply water
for the accumulated total requirement of both washes. Savings of
about 70% are available during off peak period. A time clock is
necessary to ensure that after the evening milking, the element
does not switch on until the off peak period is reached. Note:-
you must have an off peak electric meter and be on an Economy
7 type tariff with your electric supplier to make this saving.
Time clock - Where economy 7 or
low tariff electricity is to be taken advantage of, a timer is
essential to optimise effective energy saving. When power is used
at standard rates it will ensure the element is not turned on
until such time as required, resulting in energy cost savings and
an extended element life.
Use of stands - A range of easy assembly galvanised stands is
available in three heights for each size of water heater. Wall
mounting is possible for all sizes below 225 litres. It is however
highly recommended that stand mounting be used for all larger
capacity heaters. Under no circumstances should the
retaining brackets or side strips that are fitted to models 225
and above be used for wall mounting. These brackets are provided
for security to tie stand / floor mounted heaters to the wall for
Float / solenoid
fill - A safe and low maintenance electrical float system
employing a wide angle anti-limescale float switch operating a
solenoid valve through a low voltage safety relay.
Vacuum required - If you choose
to have the vac-pac as an optional extra, this requires direct
connection to the milking parlour vacuum system, to ensure correct
operation of the heater.
